Actually, I'm not seeing this. In 4 speaker mode, the rear speakers have no bass, just the fronts. In 5.1 and 7.1 modes, no speakers have bass, except the sub channel. The speaker equalizer makes it look like you can control this crossover for each speaker, but boosting the bass on the rear channels has no effect. This may be OK for a car environment, but I would prefer getting full frequency response from each speaker.- The Roadie, when in 4 speaker mode sends equal signal to all four speakers.
Also, WAV's (windows sounds) and synthesized voice play on the front channels only. This might be a nice feature, actually, but it would be nice to have control.
Also, WinAmp 2.9.5 (the recommended one for RR) only plays music out the front channels, when in 4 speaker mode. Windows Media Player, iTunes, and the latest version of WinAmp make use of all 4 channels, but without bass to the rear.
This is in contrast to my ALC650 AC97 onboard sound which does play full range out of each speaker. However, the onboard sound system has weak mic inbput. A powered mic would be needed. And this leads me to the reason why I'm still keeping the roadie... it has a +20db booster for the mic input, and passive mics work great.
I'm also keeping it for the S/PDIF input for use with the Sirius tuner.
Note the Roadie doesn't come with any kind of AC3 encoding software, so the S/PDIF output is only 2-channel.
