Wow....disappointing results from the dual XV15s...that is surprising to say the least.

Are you absolutely certain you did your best setting them up? Did you do the sub crawl for each sub and did...

OK, after living with the dual T-18s for a couple days now, I've got a couple observations:

The subs are more "subtle" than my previous quad XS15s....they don't draw attention to themselves as...

Lowell,

The trace should be the same regardless of the MV level (unless you are high enough to start compressing, and -20 is certainly not loud enough for that). Something else had to change...

If so, that is strange.......

I said that because when you output to CH4 (LFE) with REW, it's 10db louder than all the other channels. Is my thinking wrong here?



Anyways, new compression sweeps! Audyssey on, MV0.

OK, with just a quick listen, I think they are sounding better without the DSP.

I seem to have more tactile feedback and even more headroom (will do some compression sweeps in a bit).

Sweet! That sounds like the easiest way to go about it....but wouldn't the db level be off then?? I suppose you just subtract the 10db then? But wouldn't you end up at the same place?

I can't believe you don't know about the MiniDSP yet....it's a very useful tool, especially if you use REW.

I had the level at -3db and the MV at 0 and REW complained at me. I'll have to try the mic lvl trick tomorrow.

Should I measure just the LFE while doing this (CH4)?

I did some today, but I didn't run out of headroom before REW refused to measure any higher (~115db).

Anyone know how to get REW to measure higher??
