Aperion Audio Intimus 533-T loudspeakers and Intimus S8-APR subwoofer


(Here's another Aperion review that got canned when they replaced these with a new model. Aperion Audio is an interesting company...they're based in Utah, but their stuff is manufactured in China. Still, they offer huge bang for the buck, a great return policy, free shipping, etc.)

If you're like me, you have a lot of non-audiophile friends who are constantly asking you for audio recommendations. This is especially true of loudspeakers. Being an audiophile apparently means that you not only know which speakers are the best, but the best ones for them. And that can be quite difficult, because your buddy is looking for something that really rocks, pumps out the bass, and looks bitchin' as well. Oh, yeah...and they can't cost a lot of money, either, or their significant other will skin them alive. In other words, they want it all, they want it now, and they want it for five or six hundred dollars max. They can maybe push it to a grand or so if they brown bag it for the next month or two, and buy the significant other something nice and sparkly.

I've always balked when making such recommendations. For a grand, I'd lean toward a nice set of small but high quality bookshelf monitors. And while my buddy might learn a thing or two about midrange purity and superb imaging, he is still going to ask a lot of questions about bass output. He has non-audiophile buddies, too, and he needs to impress them as well. And what about the babes? Babes love bass!

Eventually, this conversation will turn toward subwoofers, and while there are many three-piece speaker systems that can be purchased for well under one thousand dollars, I'm not about to recommend any of them. Almost every one I've heard had a big problem with low frequency integration, meaning that there was a stunning lack of seamlessness between the sub and the satellites. In order to get seamlessness, you usually have to spend more money. A lot more, in fact.

To be specific, you have to spend $1149. So you may have to brown bag it for three months instead of two...

Aperion Audio saves the day (and my reputation)!
We've covered Aperion Audio speakers previously in these pages, specifically the 632-LR monitors and 633-T floorstanding speakers. If you've already checked those reviews, you'll know that Aperion is a little different than the majority of audio companies out there. Based here in Portland, Aperion designs their gear here, but manufactures it in China. Okay, that may not be so different in this day and age, but Aperion also sells directly to the customer, ships for free, charges no sales tax, and gives you a 30-day no-hassle money-back guarantee. Even the shipping materials reek of incredible value. All Aperion products are shipped in solid double boxes, and every speaker is nestled in a comfy midnight blue velvet sack. Even the drawstrings are classy.

I received a pair of the Intimus 533-Ts, which are the middle model of their floorstanding line of speakers, along with the Intimus S8-APR subwoofer, which is yet another middle child. The 533-Ts retail for $375 each (a hint that these can be used for home theater applications), and the sub goes for just $399. All three enclosures were finished in cherry and were quite attractive, although one of the 533-Ts appeared to be lighter in color than the other speaker and the sub. It was slight, but noticeable. Considering Aperion's excellent reputation for customer service, I'm sure they would take care of something like this immediately.

Intimus 533-T tower loudspeakers
I started off by plugging the 533-Ts into my reference system without the sub. A relatively tall, slim design, the 533-T consists of two 5.25” woofers and a silk-dome tweeter in a ported enclosure. With a 89 dB sensitivity and a steady 8 ohm impedance, the 533-Ts should be fairly easy to drive, even though Aperion recommends at least 50 watts per channel to drive them. I used both a Nagra PSA (100wpc) and a McIntosh 275 (75wpc) just to be safe.

I immediately liked the sound of the 533-Ts, noting their smooth and warm demeanor. If I could describe them in one word, it would be clear. I'm not talking razor-clear or ultra-detailed, but free of edginess and distortion and other artifacts that can get in the way of the music. They might have been lacking in that organic, natural, I-can-hear-you-breathing sonic presentation that more expensive loudspeakers manage, and I found the soundstage to be slightly narrow as well, but for $750, the overall sound quality was nothing short of amazing.

The one thing they didn't do was deep bass. Aperion claims that the 533-Ts only go down to about 65 hz, which sounds about right. I guess that's why they sent me the sub!

Intimus S8-APR subwoofer
The S8-APR sub is powered with a built-in 150 watt amplifier, and allows you to get down to about 35hz. With its active 8” woofer and its two 8” passive radiators, the S8-APR is described as a sealed passive radiating design. It's a busy-looking little cube, with only the top and bottom unfettered by drivers, connections and controls.

The rear control panel contains for pairs of binding posts for a speaker level connection, and two pairs of RCA jacks if your preamp has a sub out feature (my ModWright 36.5 line stage doesn't, so I went the former route). In addition, you can invert phase, switch from 120V to 240V, and choose between three power options (on, off and auto). Finally, there are two knobs for level and crossover frequency. Aperion suggests you turn both of these knobs to the 12 o'clock position, and start your fine adjustments from there.

With my new, smaller listening room, I had to back off quite a bit from this position in order to avoid whumpy, one-note bass. In fact, when I first inserted the S8-APR into my system, the output and crossover controls were just a bit to the right, and my first musical selection (“King of the Mountain” from Kate Bush's Aerial CD) caused my next door neighbors to run over and see if everything was okay. (“All we heard was a big thump, like a sonic boom!”) I eventually set the crossover frequency just a bit above the 65hz mark, to mate properly with the low-frequency limitations of the 533-Ts, and the output level somewhere around 10 o'clock to reduce the effects of the sonic boom.

So happy together...
Once everything was hooked up for a while, I sat down for some serious listening. (Well, duh.) I took a while for me to stop thinking “$1149...$1149...$1149.” That's what I kept thinking about while listening to the Aperion system, whether or not I could come up with a loudspeaker that would sound better for that kind of money. Of course this depends upon your priorities when it comes to a speaker. I'm sure there are a variety of somewhat small yet well-built monitors that could better the Aperion in terms of midrange clarity or imaging or even the size of the soundstage. But will they hit 35hz with aplomb? It's doubtful.

The Intimus system didn't prove to be outstanding in one specific parameter or another. It was simply well-rounded, and it offered a level of sound quality that easily surpassed its modest price. And once I could get all of those monetary qualifiers out of my head, I simply relaxed and enjoyed some of the richest, deepest bass I've experienced, coupled with very smooth upper frequencies. And while the soundstage was relatively narrow, it was deep, subjectively extending behind the back wall of my listening room.

Did this combination achieve that aforementioned seamlessness? I have to admit that it did take some work. At first I recognize that the sub did sound detached from main speakers. Fiddling with the crossover frequency did make a difference, but I had even more success by experimenting with placement. The S8-APR isn't a wallflower, happy to be stuffed in convenient nooks and crannies. It likes to be the center of attention, which mean placed midway between the 533-Ts. Only then did I experience a cohesive, balanced sound.

So at last I've found an affordable loudspeaker to recommend to my non-audiophile buddies, and some of my audiophile ones as well. Aperion Audio has created quite a bit of buzz of late, and after spending some time with one of their middle systems, I can easily understand why. I'd love to hear some of their more ambitious designs, as well as maybe one or two of their small monitors. I know that they tend to stick to the same basic drivers throughout most of their designs, so that means there is a definite Aperion “sound.” And that, my audiophile and non-audiophile friends, is a good thing.

Aperion Audio Intimus 5B loudspeakers


(This was written in June 2009.)

It was the proverbial dark and stormy night here in the Pacific Northwest, and I had my reference system ripped apart and spread all over the floor of my listening room. I had old stuff going out and new stuff coming in, and I was making room, dusting shelves and cleaning jacks in preparation for the new set-up. Suddenly, I had a hankering to listen to my UK pressing of XTC's English Settlement (more specifically, “No Thugs In Our House), and I glanced around for a quick solution. I saw an unopened box containing a pair of Aperion Audio Intimus 5B mini-monitors. I thought to myself, “I can get these up in running in a couple of minutes,” so I grabbed a box cutter and got to work.

In no time I had the 5Bs sitting on the floor, hooked up to a SimAudio I-7 integrated amp via a pair of Audience Maestro speaker cables. I hadn't received a pair of stands yet, so I figured I'd at least get them broken in a little beforehand. Then a funny thing happened. These tiny little Aperions sounded really good just sitting there on the carpet while playing “Runaways” and “Ball and Chain” and “Senses Working Overtime.” Sure, the soundstaging and imaging were slightly askew and earthbound due to this haphazard arrangement, but these speakers sounded full and detailed and pleasant. I was able to get through all four sides of the LP easily and even moved onto a couple more LPs.

“I can't wait to get these set-up properly,” I thought.

Coming back to earth...
After getting these broken in and positioned on Sound Anchor stands, the hyperbole lessened just a little bit. These little speakers aren't quite the Second Coming, but they still offer plenty of value and performance for their size. The Aperion Intimus 5B, the “middle child” in the Intimus bookshelf range, takes advantage of Aperion's new 1” silk dome tweeter and redesigned 5.25” woven Fiberglas woofer as well as their custom HD-X3 crossover. My pair arrived with the “furniture grade” cherry finish that looks like it was carved from the same log as every other Aperion speaker I've seen. The veneer is real wood, however, which is becoming rarer at this price point. (Glossy black is also available for the same price.)

When I removed the Intimus 5Bs out of their very thorough packaging (which includes the ubiquitous Aperion purple velvet bag with yellow drawstrings, a nice touch), I truly wondered how much was left for the drivers, crossovers and cabinet. Manufacturing these speakers in China and selling them directly certainly saves a few bucks, but Aperion also offers free shipping, a 30-day money back guarantee (including return shipping), a 10-year warranty and excellent customer support. Considering that these speakers cost only $450 a pair, you may start to wonder how this Portland-based company makes a profit.

Feeling the Illinoise
The Intimus 5Bs wound up performing their best with a little bit of power behind them. These speakers are relatively inefficient (84 dB) and have a steady 6-ohm impedance. While I started with the 150wpc solid-state SimAudio I-7 on that fateful, inclement night, I eventually tried the new conrad-johnson LP66S tube amplifier which offers 60wpc. The 5Bs sounded a little more soft and indistinct with the CJ, and dynamic contrasts seemed to retreat into similar shades of gray. Aperion recommends at least 25 wpc for the 5Bs, but I'd go a lot higher just to preserve that full sound. The I-7, therefore, stayed in the system for the remainder of the review.

After extended listening sessions with the I-7 at the helm, I still felt that the bass performance of the 5B was genuinely impressive considering the size of the enclosure. According to the specs, the 5Bs are down 3 dB at 75 Hz and down 6 dB at 62 Hz. I felt, however, that the added body in the lower frequencies was due to a bump in the mid-bass response, not unlike a classic LS3/5a. While I'm not a fan of added colorations, I do prefer this type of sound to some modern mini-monitors that cut off suddenly under 60 or 70 Hz and remove the foundation completely. (In most cases this presupposes the addition of a subwoofer.) The soundstage was surprisingly large as well, extending well beyond the boundaries of my listening room. Again, I had to shake my head in disbelief that a speaker so small and inexpensive could get these fundamentals right.

The 5Bs ultimately came up short in the delivery of inner detail. I imagined a child coloring with crayons, getting all of the borders and lines perfect but becoming suddenly uneven and shaky when it came to shading the interiors of those shapes. On Sufjan Stevens' Illinois, for example, I couldn't hear as much air and separation between instruments during complex and busy songs as “Come on! Feel the Illinoise!” or “Decatur, or, Round of Applause for Your Stepmother!” (Yes, those are real song titles.) These instruments would blend together as if the musicians were sitting in each other's laps, especially if I turned the volume up a bit. More intimate and streamlined selections such as “John Wayne Gacy, Jr.” and “Jacksonville” fared much better, with Stevens' voice sounding appropriately breathy and fragile.

One more caveat involves the grille covers. It's been a while since I've heard a grille cloth alter the overall sound of a speaker this drastically. With the grilles in place, the treble became excessively grainy and harsh, and I thought I had finally found the Achilles' Heel of these little speakers. Once these were removed, the upper frequencies smoothed out considerable and even took on a slightly liquid and warm character. Finally, there's the standard disclaimer that accompanies most mini-monitors...don't turn them up too loud, and don't think you're going to impress your buddies when you play the new albums from AC/DC, Metallica and Guns 'N' Roses.

But did I mention the price?
It seems kind of silly to nitpick about dynamics and loudness with a $450 pair of speakers that are just slightly larger than the aforementioned LS3/5a. As good as these are as stand-alone speakers, I'm sure that they realize their potential when mated with one of Aperion's subwoofers. (I've used one of these in the past and found it to be another outstanding bargain.) I also discovered that the 5Bs are excellent near-field monitors and might be the perfect speakers to hook up to your computer. Aperion recommends them as an excellent solution for gaming as well. In this type of application, the 5Bs will allow you to hear deep into a recording while retaining the same sense of scale as in a normal configuration.

The repeated use of terms such as “near-field monitor” and “LS3/5a” and “mid-bass bump” in this review may be a clue to my true feelings about the Aperion Intimus 5Bs. Are they a poor man's LS3/5a? I was able to hear the Stirling Broadcast update of that venerable BBC monitor for a couple of months earlier in the year, and I was constantly reminded of them during my time with the Aperions. I think the Stirlings possessed that inner detail that the 5Bs lack, but at nearly four times the price. If I needed a small speaker for a small price, however, I'd probably choose the Aperions. If I needed a small speaker that sounds good while lying surreptitiously on the carpet, the choice is even more obvious.
