Quite. I cross over to my dual Submersive F2s at 100Hz (mains) and 110Hz (surrounds) and I am totally awestruck by the quality of the SubMs.
One Submersive is sublime. Two is divine.
True, but only XT32 does a *really* good job on the bass and the entry level price for that is the Onkyo 818 which is around $1,000 - way more than an AntiMode, which may well outperform lesser versions of MultEQ. But he has a couple of options on the table now thanks to me and you spending his money for him LOL :)
That is true, I think. I say 'I think' because I observed huge differences between XT and XT32 when going from one to the other. If I had an AVR that had less than XT32, and didn’t want to upgrade it, I'd try to find a secondhand SVS AS-EQ1 and, failing that, I'd get an AntiMode.
:) Sorry, Jerry. I am a Submersevangelist and am bound by my terms of membership to such an exclusive club to remind the less well-endowed of what they are missing :)
Incidentally, anyone with any sort of decent sub setup, that can dig low and go loud should listen to the first 5 minutes of the Bluray of 'Dredd'. OMG. I thought my house was in danger of auto-demolition - I had to turn the MV down by 5dB!! The movie looks like mindless cr&p though - but when the soundtrack is as good as that, I can forgive it. And my bass is calibrated of course and I am only running the dual Submersives hot by 2dB currently.
Yes, XT32 is a very significant step up, as you are finding. Kudos to you for treating the room and measuring...
Assuming you ran the Audyssey calibration, I would trust the speaker trim levels that were set by Audyssey and not change anything by measuring with an SPL. The SPL will not be as accurate. I would also raise the crossover to 80Hz. Your sub was designed to handle the low frequencies--let it do its job. Then I would sit back and enjoy the system for a while!
If you have a competent sub I would try raising the XO to 80Hz or even higher. You will be sending the bass to the speaker specially designed to handle it (the sub) and relieving strain on your main speakers and your amplifiers. I have very good speakers and subs and I cross over at 100Hz. Read this FAQ answer for some background info...
It's been a long time since I played drums - I just played that track on my Mac (it does have reasonably good speakers attached) and they sound like toms to me. Congas are usually struck with the fingers or palms of the hand, not with sticks. I'd have to play it on the main system to be 100% sure what I'm hearing though. Incidentally, congas aren't going to be much use for evaluating proper bass - they are pitched way too high - I'd guess they don't get below 120Hz or so. Not that the OP said he was using the congas/toms for bass evaluation - we got sidetracked into a bass discussion I think. Floor toms will go much lower (about 60Hz) though. Mounted toms will depend on the tuning - say 80Hz and up. I'm guessing these frequencies BTW.
One of the problems of setting up by ear is when congas sound like toms! ;) I think the only way to really set up subs (especially dual or multiple subs) is with measuring gear. But once they are measuring well, my final test is by ear using some of my favourite bass guitarists - Clarke, Pastorius etc - or my favourite double bass players - eg Mingus, Ray Brown etc. This works well down to about 40Hz (open E) but of course if we want to evaluate lower, then it has to be a movie track or a test disc track. BYAKT.
