Subwoofer: should we even use them at all?


Dear Community,

For years, I looked forward to purchasing a subwoofer. However, I recently became friends with someone in this field who is much more knowledgable than me. His system sounds amazing. He told me that subwoofers should be avoided because of the lack of coherence that inheres in adding a subwoofer. What do you guys think? I currently use Verity Parsifol Ovations.

My mains in my main rig are rated -3db 55Hz, while my office monitors to 44Hz. In either case, I can listen to a lot of music and be mostly satisfied without a sub for acoustic, vocals, jazz, blues, etc., even some rock. But there are times I do not want to be MOSTLY satisfied. And for those times, and when I wish to crank it, I employ a pair of 12" powered subs in my main rig.

The deep, visceral, gut-wrenching, grunt of those subs can fill in the missing parts, transporting me to musical Nirvana and change my MOSTLY satisfied experience to COMPLETELY satisfied. I'll never live without a sub (and preferrably at least two) regardless of how wonderful my mains are.
Elegal,

Ideal placement of a subwoofer is most often far from ideal placement of mid/tweeters. If you put a sub in the same cabinet as the other drivers, you'll end up with (pardon the pun) suboptimal placement of one or the other.
I love the pun! And thank you for a great answer. Perhaps they could design systems with a separate sub with suggestions on placement?
Elegal,

Those do exist. Duke at Audiokinesis makes a really interesting speaker system with your choice of two different subwoofer arrays, one sealed the other ported. There are four subs with four channels of amplification in either array. I think it's worth visiting his web site to check out.

There are also traditional 2.1 systems out there, tho not as many as there once were.
