Do you think you need a subwoofer?

Thanks Raul.

Our room is also asymmetric in the L/R direction. The L speaker is a little over 1m from its side wall, the R speaker is over 2m. The furniture in each direction is different too, which should also help break up standing waves.

Both speakers are open to another room behind them. They have nearly 5m behind them and at least 3m in front, plenty of room to breath. I'm sure this contributes to our excellent soundstage depth, imaging and air.

It sounds like side-firing woofers could work very well in this setup, though we'd have to have to have them facing out. (Facing in would aim a woofer directly at the TT and amplifiers, not a good idea!)

Many thanks again for this excellent thread,
Doug

Dear Doug: " +++++(Facing in would aim a woofer directly at the TT and amplifiers, not a good idea!) " +++++

Well, it don't seems like a good idea but in my system both subs are facing my three TT's and I never detect any problem cause by the sub's. You have to try, I'm almost sure that you will not find problems about.

Regards and enjoy the music.

Wow. Like you say, sometimes things that make no sense work fine while other things that make good sense fail. Try everything!

This may not mean much but I thought I'd share abit along this theme about 'tables and LF speakers. My old Aerial 10t's are rear ported and just drip with chest pounding bass, even when pulled out 6 to 7 feet from the back wall. I once used a decibel meter and found that if I pulled the equipment stand out at least 18 inches from the back wall that the LF build up dropped off dramatically. Also, it was best to avoid the area equal distance between the speakers along the back wall.

Dear friends: For almost two years I was running the crossover frequency between my main speakers and the Velodyne's at 85-90 Hz.
It sound very good and let free the main speakers for the low bass reproduction responsibility lowering the Intermodulation Distortions level. The issue with that crossover frequency is that the subwoofers are reproducing frequencies that are not only out of its best frequency range of perfect quality reproduction but that those " high frequencies " are recognizable coming from the subs and " interfering " with the overall quality sound reproduction.

Two weeks ago I begin trying other croosover frequencies and ( today with my ystem ) I find that 60 Hz ( I try down to 40 Hz )is the way to go. This crossover frequency change makes wonders on the quality sound reproduction of my system, specially on transparency ( see through ), detail, immediacy and overall soundstage. Through this change my system is a " new system ", a lot better quality sound reproduction audio system, I'm feeling nearer to the recording, nearer to the live event with an increase of music emotions.

Well, like any of you I'm always looking for a better way to go, fortunately ( till today ) almost always exist that better " road ".

Regards and enjoy the music.
