With that in mind would the jump to the ultra provide more enjoyable low end experience even at those low levels or am I wasting my money? Also I should note that I have found dynamic volume and eq impact what master volume I use. For music I turn dynamic volume off and I then have to bump up master volume significantly higher. I use the "evening" setting most of the time for movies which helps when we are are listening at lower volumes with the surround and lfe channels but then need lower volume settings as above.
You are very welcome! Just as there is a relationship between DEQ and MV, so there is a relationship between the amount of sub boost you employ, and how much low bass you hear, even at fairly modest master volume levels. Someone on the Nearfield Ported MBM thread asked at what listening volumes people could feel tactile bass sensations. I replied that I could feel tactile mid-bass (chest pressure or punch, from about 50Hz to 100Hz) at much more moderate volumes, and with much less bass boost, than I could with ULF frequencies. Much less!
So, when you boosted you sub by about 8db, post-Audyssey, you started to hear more of the deep bass, characterized as a rumbling sound, than you did when you were using less sub boost. It would be the same thing with the Ultra. If you boosted your sub, more than you have in the past, you would be able to hear, and feel, more low bass sounds and sensations than you would be able to with your PC2000, at comparable MV and sub levels. And, that's because the Ultra can play lower frequencies, louder than the PC2000 can. But, it would still be contingent on using enough sub boost to engage those low frequencies. I hope that all makes sense.
I honestly don't know whether buying an Ultra would make a significant difference in your listening experience, or not. But, I do know that the question of whether you might be missing something, and whether you should upgrade in order to find out, has been bugging you for a while now. So, if you don't mind a suggestion, this is mine. If your credit card will stand it, I would suggest that you buy a PC13, with the understanding that you may, or may not, trade-in your PC2000.
I feel sure that SVS will work with you on that. Put the PC2000 away for a while, and experiment with the PC13. If you like the additional low frequency extension it provides, keep it and send the PC2000 back. If you don't feel that it is a worthwhile upgrade, considering either the size, or cost difference, just send the PC13 back. Again, SVS won't object to that. The Customer Bill of Rights is there to be used, and the SVS customer service is outstanding.
