Single vs Dual Subs

Didn't this issue come up in a series of posts a short while ago? One of the posters cited the Harmon web site. Their expert advice based on psychoacoustic research differs from that given in these posts. Given that LF has little or no directional information, a high quality sub well placed is usually sufficient except for very large spaces. Well placed is often in a corner. You might Goggle harmon, where you will find a series of technical papers dealing with various aspects of audio, including LF reproduction.

db,

I don't know the paper in question, but IME 2 subs vastly simplify the task of achieving smooth response. In room, you WILL get peaks and valleys which can be smoothed (to an extent) by varying the location of your sub. When you have the option of varying the location of 2 subs (and their phase/polarity), the chance of significantly mitigating all major anomalies is much greater. Again, IME.

The actual performance of the sub itself may also benefit significantly from the addition of a companion, depending on room size and placement (as you noted), as well as desired spl and program material.

Most subs are crossed oved at a point high enough where the sound is directional.
