Horn Speaker Recommendations

I think you would be doing yourself a favor if you purchased a moderate size horn and accompanied it with a pair of the Wilson Beseech Torus infrasonic generators. They are breath taking, fast and very deep and extremely musical as well as accurate. To get a horn to go that low and be that fast is really difficult. In addition and it is no small mater with the Torus you will be happy using them with any main speaker you ever buy.

Wilson Benesch Torus retail for $12,900 with the amp/crossover. I am not a dealer the distributor is Aaudio Imports in Colorado. If that is too rich for you blood I would suggest a couple of small diameter subs, say 8" or 10" so they would be fast enough to keep pace with horns.
