Like most enthusiasts, I am forever on the hunt for cost effective, easy to implement, system improvements that can coax more performance from my home theater gear. The biggest roadblock is separating true game changers from snake oil prior to opening the wallet – after all, who wants to spend valuable coin on a product that simply exists within a system without any appreciable impact? If you’ve been in the home theater or two-channel game for a while, then you probably can jot down a laundry list of products that simply do not (and never will) live up to claims. That’s what makes the subject of today’s review a breath of fresh air.

Great review Todd. They really do make a difference in the demo videos I watched. I have the HPS SR70 speakers which are really commercial grade Heresy's. I sent them the dimensions to see if they have something that would work for me instead of the normal risers that come with the Heresy's that I was going to order. I have my speakers on carpet now so if they do make stands I can use I will have to put some wood or stone underneath the speaker for the stands to sit on. Thanks again. TC.

Thanks, TC.

They definitely have a product that will fit your needs - most likely a custom cut modular model. Based on the Weight of your speakers and the potential size of your speaker stands, you most likely won't need to put anything over your carpet. The folks at IsoAcoustics are very customer friendly...

The stands are the real deal. Very cool stuff.

Sounds great, I will ask them about being on carpet when they get back to me. Hopefully tomorrow. I have been putting off ordering the risers because I really just don't like the look of them. Maybe this was why...:T

Of course it was why! :sn: Let us know what they say (and recommend). I'm sure there are others in your shoes...

Excellent review Todd, thank you very much.

My friend and I were just talking about a good way to raise and decouple the subwoofers from the floor. He noted that by raising his Velodyne off the floor a bit tended to tighten the bottom end and as such I was going to build something as well. This appears to be a good way to handle this situation and we wont have to construct anything.
Again, thank you.

Todd,

You should contact mapleshades and see if you can demo their products and do the same exact testing. They offer returns on purchased products so I'd assume you could do a demo for a review.

I'd be curious to see if you note any differences in their products as well. As we all know there is many many products available.

Definitely! Just to note, the Modular stands lifted my subs 5-inches off the floor. The sub is completely decoupled... It's a great option.

I'll check their products out...if something can be arranged, I'd be happy to write a review!

I think your main difference in the audible differences will be heard over the 2 channel listening due to the stereo imaging. The decoupling/isolation provides less lateral movement keeping the voice coils/cones more inline than if they were just sitting on the floor/carpet. One key point I read in your review is by using this product you then can fine tune the alignment of the speaker and I'm assuming much finer/precision than just using spikes under a speaker which are rudimentary in their ability to achieve perfect alignment. Could this better alignment attribute more to the audible differences than the isolation itself?

I suppose what I'm saying is... do we need isolation on the speakers as much as we need critical alignment... so if we had a stand that would allow easy precision adjustments on 5 axis (front/rear, side/side, up/down, tilt forward/reverse, tilt left/right) Something much easier to dial in than adjusting 4 spikes to get this accuracy.... which is why my uncle also says using the maple blocks aids in the fine tuning due to providing a hard surface vs. carpet to work with.

There are lots of critical adjustments that can be made to speakers, each one bringing out better sound. Obviously, alignment is key. Getting speakers away from boundaries is another. Most HTS members, including yourself, are probably well aware of these various factors...so, I agree with you that positioning is a big deal. What the isolation stands introduce, more than anything, is managing the response of the speaker in the fore and aft direction, while resisting lateral movement which can cause a bobble-head like movement and lost focus.

I did touch on positioning in the review. These stands can be ordered to be much taller than the ones I reviewed (and can be adjusted to tilt)...so, technically, you place them on speaker stands, a desktop, etc, and truly align tweeter levels with ear level (if that's what you're aiming for).

I agree. Would you be willing to run Room EQ Wizard with and without one of these stands in place? I suppose the easiest test for you is with just one speaker playing, and the center makes sense because it's full range rather than just bass (subwoofer). You'll need a block of wood or a few books the same height as the isolating stand, because speaker height affects the response. A test like this would be much more valuable to me than subjective assessment, and I presume more valuable to others too.

Thanks!

Hi Ethan,

I did take measurements...with speakers height adjusted to keep it an even playing ground. Below are images (1/3 smoothing) of subwoofer only, two-channel (full range), and two-channel with subs.

Regards, Todd

Excellent! Thanks Todd. But now you got me really curious. :D

Since you have the data, can you post the same with no smoothing, and also hi-res waterfalls? Or better still, would you be willing to post the mdat files? This is something I've always been curious about, and nobody that I know of has ever measured isolation type speaker stands.

Shoot me a PM with your email address and I'll send the files to you...would be great to have your expert eyes look them over...perhaps you can post some of the results you find interesting?

I'll get those to you later today!

As for the room...it's a 12X17X8 dedicated room, carpeted with pad.

Front wall corner traps: 54" tall and 24" wide - 8" thick absorption
Two front wall panels: 48"X24" - 4" thick absorption
Rear wall corner traps: 54" tall and 24" wide - 8" thick absorption, FRK facing
Rear wall binary slat diffuser - 6-feet wide, 5-feet high, with 2" thick absorption. centered on wall (1-ft from wall)
First Reflection points on walls treated with 2" absorption panels.

The room is completely blacked out, with minimal lighting, so pictures really are tough...but here are some images of the kinds corner traps and the rear wall diffuser/absorption panel after they were made...
