I was talking about >100hz frequencies.

Either way; It's not really made of a material that is going to be very effective at sound wave absorption.

When the deadener absorbs the sound, you lose SPL (cabin pressure), but gain Sound Quality. Correct?

The ability to control the reflective surfaces and tactile transmission of frequencies aswell as block road/engine/wind noise greatly increases the "sound quality" of the system and lowers the noise floor by a good margin.

But there's no noticeable decrease in output level from the stereo as a result of using deadening.

To actually absorb subbass frequencies, foam needs to be multiple feet thick. So SPL wise your not loosing much of anything there either.

We know Deadener stops rattles and such, but if too much is used, then it starts to absorb the SPL you are wanting. That would be my guess.

That still makes little sense.

Maybe some hardcore SPL-only competitors notice a small change in their score for whatever reason. I don't know there...not my thing nor do I care.

But for the daily driving or sound quality oriented system......the more sound deadening, the better. There will come a point where the additional cost is not worth the marginal benefit. But that's a completely different subject.

I see what your saying. I agree.

The other main thing I was trying to say was that, the first layer of deadener, wherever you use it on your Car, Trunk or SUV, is the most important. So make sure you tuck it in the crevas's(sp?) and such. Learned that the hard way, the REALLY hard way.

orly? what happened?

if deadener mat and liquids hurt spl then spl people wouldnt use it...fact that spl people use a great deal of it and in classes are limited to the amount that they use.... basically they use it to make for better rigidity

is edead v1se2 good at all though? if your on a budget for deadener?

I would say it is a decent budget deadener.
