Fix for Bass Redirection issue in sig

Question

Hi everybody,
I have just ordered a Teufel Concept E 5. Speaker System. For that reason I'm now also dealing with the purchse of a 5. sound card. At first my favourite was the Audigy 2 ZS, but now I'm hesitating because I've read on several forums that the Teufel System also suffers from the Audigy series' malfunctioning driver-implemented Bass Redirection (an issue firstly reported 3 years ago, January 2002!!!) when it comes to upmix a stereo source to 5..
Just to remember: If Bass Redirection is unchecked in the drivers, the whole frequency spectrum of the stereo source will be directly sent to the front left/right channels (and no other channels), and the connected speaker system will have to split the frequency bands and feed its subwoofer with low-pass signals and the sats with high-pass signals (For example this is the case with Creative's own speaker systems which have internal crossovers). But most non-Creative 5. Systems don't have this internal functionality of mixing a stereo input up to subwoofer and sats. For such systems Creative implemented the "Bass Redirection" in their drivers: sub frequencies of the stereo source are low-pass filtered and sent to the discrete subwoofer output of the sound card. The issue is that this signal from the subwoofer output is too weak, forcing users to find workarounds to get bass when they're listening to stereo sources (such as Music in Winamp).
This issue, although known for 3 (three!!!) years now, has not yet been fixed by Creative. In late November 2004, Cat has replied to the Monster thread dealing with this issue on the old forums (http://uk.europe.creative.com/support/forums/thread.asp?thre=396&foru=5&page=34) (scroll down), promising to forward the issue to the driver dev team, but since that day nothing has happened anymore.
My question to the mods: is there a chance that this driver issue will be fixed in the near future? Otherwise I'll have to reconsider my options concerning my sound card purchase.

Answer 1

I have the same thing with this option -and I asking for fix (again....)
I have Audigy 2 ZS OEM, Yamaha RXV-440 Home Cinema Recei'ver and big 5. home cinema speakers. Audigy 2 ZS is connected to Yamaha by 3 analog outputs (connecting it by spdif cause no CMSS stereo to surround upmix and only stereo sound for all none DD/DTS sound sources like MP3, games, mpg/DivX/XviD films...thats why I must connect them by annalog outputs/inputs).
When I disable bass redirection then speakers have full frequency response (20Hz - 20kHz) but there is no any signal on sub output (when I play stereo sound with CMSS Stereo Surround enabled).
When I enable bass redirection and set cutoff frequency to 70Hz then there is signal on analog sub out but speakers have bass cutted off (20Hz - 70Hz) and playing only frequencies from 70Hz to 20kHz
This option causing waste of basse from speakers (they have beatyful basse but no with this drivers).
Even when bass redirection is enabled, signal from sub output is very weak - I don't have so high sub volume regulation to turn it sound loud enough
I have this problems on SB Li've, I have this problem on Audigy 2 ZS and this problem still exist on Audigy 4 !!! (I'am using now modded Audigy 4 drivers to work on all Audigy series but there is the same problem as in orginal A2 ZS drivers).
I'am requesting only 2 fixes in drivers that is satisfy me completly (not only me - many people have the same problem):
. Add an option that will disable bass cutting from speakers when bass redirection is enabled or make bass redirection working only for subwoofer without any speakers frequency cutting.
2. Make signal from analog sub out louder because this volume level is not acceptable !!!
Please...
This problems causing that I starting to think about some other sound card from other producent...because that can't be Message Edited by FPPfan on 02-0-2005 08:52 PM
