I know the topic of bass management comes up quite often, but I was reading a thread on bi-wiring yesterday and HTF member Nick G provided a link to a thread in the AVS forum concerning bass management:
http://www.avsforum.com/ubb/Forum3/HTML/003524.html
It is a very informative and enlightening read on the proper subwoofer use, setup, and management, but something that was stated in that thread (and has been stated in this forum as well) concerns the subwoofer's crossover level.
I realize most receivers have a crossover set at somewhere around 80 Hz, which (correct me if I'm wrong) normally will send all above-80 Hz material to the speakers and below-80 Hz material to the sub.
The AVS forum stated that since Dolby Digital and DTS 5.1 encoded DVDs have a dedicated LFE channel, then you should set the sub's crossover to MAXIMUM. The rationale behind this is that in the LFE channel, there is bass mixed at above 80 Hz levels meant to be sent to your subwoofer as it is a dedicated LFE channel. In theory, then, if you set the sub's crossover at 80 Hz (or whatever level below maximum you set), you will lose low frequencies (above the crossover level you have selected) that were intended for the LFE channel.
I'm sure this is true, but if the receiver's crossover is still fixed at 80 Hz, shouldn't your mains still be getting frequencies down to 80 Hz? And if your mains can handle these frequencies, why wouldn't you want THEM, rather than the sub, to produce these frequencies. It would seem, in theory, to be a better balance if the mains were able to handle some of the bass. I guess the flip side of this theory is that, since the sub is designed to handle strictly LFE, why shouldn't it produce ALL of the LFE?
I have tried setting my sub at the higher crossover level (120 Hz) and the bass just feels TOO MUCH. Not too deep, but just too much. It doesn't sound as balanced as it did before (when I had the crossover set at around 90 Hz). I love bass, don't get me wrong, and I like it loud, but with the crossover set to max it seems like there is an omnipresent level of bass that, to me, makes the soundtrack sound a bit unnatural. The AVS forum expert (Brian Florian, I believe) would say that I need a better sub if this is the case. I have a Paradigm PW-2200, and, while not the best sub, is quite a capable performer. So I don't think I need a new sub....yet...
I know that many people will say, "whatever sounds best to you, then do it," which I agree with. But I just was wondering if it is inherently UNACCURATE (with respect to the filmmakers'intent and the DVD sound mastering intent) to NOT set the crossover to a maximum level.
Just curious...
