So, I got both of my volt 8s wired up last night. I've experimented with 2 types of sound damping material. I've got some flat foam, about 1 inch thick, and some mattress topper egg crate foam (all I could find at the stores) which is about 2 inches thick.

In both instances, I connected the speaker to my center channel to see how they sound. Everything is great until I get some of the male vocals and low female vocals, and some explosions. I'm guessing this is in the 250hz range. The sound is a bit echoey... kind of a hollow, tinny sound. It's not very much, but I can slightly notice it.

So, should I change to some other sort of sound damping material, or am I just expecting too much from these speakers..

Thanks!

I would try eq first. Add a 2db boost at 300 and maybe 1db at 400hz. So many factors with room being biggest culprit. I have a few demo tracks I use for voices. I know them well and rely on them more then measurements. Measurements can help isolate the frequency. I find with most minor issues eq works great . big issues need room treatments.

I don't have a mic that is specifically designed for making response measurements, but I do have some PC mics for voice chat. Would that work, or do I need a special mic like a Dayton EMM-6?

Yes I did have Audyssey active, but it was configured for my other speakers. I didn't think that would make that big of a difference, but I'll try running Audyssey with the Volts.

I'll have to see if my receiver offers the ability to set gains at selectable frequency ranges. I think the only option is Audyssey or a flat DB boost. It's a Marantz SR5007.

Thanks everyone!!!

I had the same thing happen to me when I added my Finalist Center Channel. I left the previous audessy cal on and the sound was very tinny. Once I recalced with audessy the speakers sounded worlds better. I would think that breaking the volts in would help also.

You can use the Audyssey mic.

Every time you move furniture, move speakers, or change speakers, Audyssey needs to be re-run. It makes a big difference.

Did you use any poly fill in the speaker boxes?

I agree with the others though, it is unfair to the speakers, and actually useless to listen to speakers using the calibration from a different speaker.

Turning Audyssey off complete and listening would be better if you don't have the time for a full calibration.

Thanks for all the suggestions :) I will run the Audyssey and re-eval later today.

As for the poly fill, no I did not use any. I just used the egg crate foam on the inside. I do have a bunch leftover from my ultimax build that I could try out after I re-test with a calibration.

If your old speaker had a peak at 1000hz audyssey would cut it down. If the new speaker has a dip at 1000hz that old audyssey calibration would cut that dip ever further. All it knows is cut x db at x hz (or boost of course).

Ok, so I hooked up the volts in 2.1 config, ran the Audyssey, and did some more testing. Wow, what a difference that made. I wasn't giving Audyssey enough credit, it really does a drastic change on your speakers. The hollow sound is gone, and these things sound great! I dare say they give my mains a run for their money. The lows are a bit weaker, but still nice and smooth until the sub picks up. The detail in the mids and highs are wonderful.

After I was pleased with they way the volts performed, I hooked up the mains and got the volts on the wall, and performed a 5.1 calibration. After a little more tweaking, I had everything dialed in just right. Ran a few more tests and was very impressed by the results. I was hearing far more ambient sounds than before. It's not really a volume thing, but a detail thing. Things like water dripping, echos, distinct voices behind me, where all clear as day where before it was just a muddy mess (not that I should expect anything different from my old surrounds).

Thanks everyone!
