live sound subwoofers anybody?

[viseral audio]

anybody out there use live music speakers for home theatre, interested in turbo sound TCS-b218 double 18" specs down to 25hz +- 3db with output of up to 140db, I figure with room gain will be useable down to little below 20 hz and will have plenty of headroom.

thinking of using turbo sound TCS-b218 double 18" subwoofer specs to 25hz +- 3 db, -10db at 20 hz but output at 140db. the extra headroom would be great but not sure how good quality of sound would be. anybody else use something similar?

Unless you need 140 dB for some reason (or anything close to it), or have a living room the size of a small auditorium, you can get a home audio sub that will get below 25 Hz for less than $600.

wouldn't a higher output allow a more dynamic live feel ? thanks

A more dynamic feel than what? You doing a concert?

no but is not uncommon to listen to levels of110db not counting peaks, worried others might be pushed beyond limits.

The size of bass waves compared to the size of your room means that sound pressure is going to have an uneven distribution within the room, causing you to only be able to hear certain frequencies, at certain times, in certain places.

The only way to influence that is to add enough pressure sources (subs) to ensure all seats hear all of the bass.

One extremely powerful subwoofer will not change that!

The sub isn’t going to output any more than the program material demands. Up your budget to $1500 or so and you should be able to get as much output as home program material can generate. Again, unless you have an unusually large room.

Well THX spec would have the sub(s) be able to handle 115dB peaks for LFE plus any redirected bass....but 140 is well beyond that....you listen at average 110dB? Yow. What are the dims of your room? Might be better off with multiple less potent subs...

Yes, it is uncommon to be listening at levels of 110dB not counting peaks. If you listen at those output levels, you will have hearing damage very quickly. If that is what you want, have at it. Using live sound reinforcement loudspeaker equipment in a domestic environment is a great way to achieve that though, no arguments there.
