What's the consensus on using wood blocks under speakers to improve sound? My Mirage M5si speakers are on a carpeted concrete floor and I've read that can degrade the sound. Wood blocks/cutting boards made of maple are expensive but bamboo is quite a bit cheaper. I've read pros and cons elsewhere and would like to hear AVS Forum members views on this topic.

Not sure what your goal or logic might be, exactly, but marble or granite tiles can work well, too, if you are just trying to get a hard surface beneath the speakers.

Also, consider spikes.

As long as the wooden blocks are covered with carpet, they should work fine-ish.

The idea is to de-couple the speaker from the hard floor surface.

To do this, you would:

A) Rise the speaker off of the floor, giving the sound more room before deflecting off of the floor.

2) Use a dampener such as carpeted wood, or any manufactured dampening material.

III) Mount the speaker on legs, such as small table legs available at any home improvement store.

The reason to de-couple is to stop the speaker cabinet from interacting with the hard floor.

I know that I have seen threads where people have made there own, using 1x1's, plywood, and carpet remnants.

Alternatively, some people just use small carpets under their speakers.

I currently, have been unable to locate any of these threads, but I know I have seen them somewhere, either here or over at Bluray.com.

Maybe someone else can link to them and/or provide pix.

To the OP, are you experiencing sound issues? What prompted your inquiry?

I enquired because I've read that a carpeted concrete floor versus, I guess, a suspended wood floor is the worst place to put a speaker. I have the M5's spiked down to the concrete but was wondering if the over-all sound could be improved by using a 2" thick rectangular block of wood under the speakers. Does anyone have experience with this tweak?

No, actually the usual idea is to couple the speakers to a hard surface.

I don't think that it'll matter much.

Now, if you only had the speakers sitting on bare concrete, then you would hear a BIG difference by de-coupling the speaker from the floor.

But since, you say the floor is already carpeted, then you probably would not see much improvement by adding a riser of some sort.

That is not how I understood it, but hey, who knows.

It has always been my understanding that some speakers interact poorly with hard surfaces. To to overcome this, you would want to de-couple it, by raising the speaker in space, giving the sound more room before it starts to interact with the hard surface areas.

I gathered most of this idea from some subwoofer forums.

But I may be off base, so if someone else is in the know, then I defer...

For the record, I have never raised my speakers, and can neither attest to or deny the reality of said application(s).

Since, more often than not, we aren't really able to trully 100% couple a speaker to the floor, decoupling is neccessary.

Take spikes for instance. Some say they decouple, I say used properly they couple the speaker to the floor. The weight of the speaker is transferred to the floor through 4 tiny points as opposed to the entire bottom of the speaker. That, IMHO, couples it.

Since the OP has concrete iunderneath his carpet, he cannot couple the speaker to the floor. I don't think anything he does is going to make much of a difference.

One thing that may have an effect would be a couple of those subdudes or something similar. They may offer isolation as well as still providing a study base.

Yeah, on carpet, if it were me, I would just put marble or granite tiles (or wood) underneath the speaker with some sort of bumpers on each of the corners of the speaker's base. You can stick the bumpers to the tiles/blocks if you want to avoid sticking them to the speakers.

I didn't read the whole thing, but did not see any mention of wood blocks.

To the OP, If you want to experiment with wood blocks I encourage you to. I'm frugal, so I'd start with 2x4 or 4x4 available at lumber store. If I noticed a difference, I might experiment with other woods - No doubt each wood has different characteristics. And each concrete floor is unique. It is an area worth experimenting in. Especially since you are interested and curious.

If you put wooden blocks under the speakers, do you also have to wear Dutch wooden clogs?

That's optional, but a Dutch wooden codpiece is recommended. I can source one if you'd like.

Depends on the speaker, really. Up until a few years ago, I had a pair of Pioneer HPM-100 speakers hanging from the ceiling. The bottom of each speaker was about 3-feet off of the ground. Got rid of a touch of "boomy" bass.

Placement of the speakers in your room will mean more to the response curve and the spatial attainment than any relationship the speaker cab has with the floor. Contacting or NOT contacting the floor is unimportant in perceived sound quality.
Equidistant placement from walls AND ceiling will yield optimum soundstage. However furniture placement and room shape generally impede on best auditory practices.
You seldom see subs hanging midway between floor and ceiling . . . . because they're big . . . and because they're heavy . . . . NOT because they don't sound great.

My fading memory says Genisis "was" Arnie Nudell. As to what the author who now "is" Genisis, my take is that it's like listening to a Scientology pitch or Kevin Trudeau on an infomercial.

This reminds me of the vendor at a CES that was selling twist-ties and assorted bits of junk that he claimed would improve the sound. Many people swore they heard a marked improvement, and sales of $50 ea. twist ties were brisk.

True story.

equidistant placement yields maximum SBIR. are you insisting that is a good thing?

I've purchased some cheap but solid bamboo cutting boards that the M5's will fit on nicely. I will try them out this weekend.
