Is there anyway you can get the bass to support the 15-20hz range? I own a high end sound system with an Elemental Designs custom built 190v2 diy kit subwoofer which they no longer offer but you can ask about. It's a big 18" subwoofer that is 3 ft tall 2 ft wide and 2 ft deep. My subwoofer can go down to the 18hz range. I own the X-fi forte and I read of its frequency limitations. I tried the Asus xonar essence st but that was garbage. It crashed all the time and BF3 wouldnt work and it didn't sound as good as the hype has been giving it. I preferred the sound of my Forte. To give you an idea of my system I run Mirage OMD-28, OMD-15, OMD-5, and OMD-C2. I also have an Emotiva XPA-5, UPA-2, and Integra DTC-9.8 pre/pro. I love my Forte and really want it to sound better but I fear I'm being limited with the frequency range. The following is a real big long shot but I thought I'd ask: Is it possible to get the Xonar H6 or the HT Omega XT card to work with the Forte or the titanium HD? I love Auzentech/xfi cards and I'm loyal for life to them I just want the ability to upgrade my opamps on my card to different ones and they don't have that ability with the x-fi/auzentech cards, only the front channels.
