Speaker Asylum General speaker questions for audio and home theater. |

I've been experimenting with supplementing the LF output of a pair of active Tannoy nearfield monitors (model AMS-12A) with a pair of TAD TL-1601b in 8.5 cu.ft. cabs tuned to 32 Hz, crossed over at various frequencies from 80 to 200 Hz. Crossover is an Ashly XR-1001 that uses 24 dB/oct. Linkwitz-Riley slopes.
My first surprise is that while the higher crossover point sounded better, all configurations produced very muddy and confused lower frequencies. In fact, while the LF output was much lower without the TADs-no surprise-it was much more articulate and coherent.
Then it occurred to me that what I was hearing was very much like what I hear when accidentally hooking up speakers with the polarity reversed. So I reversed the polarity on the TADs and the system sounds much more natural and coherent. Is there some way, other than my perhaps hooking up the drivers with reversed polarity-don't think I did, but I'll check-that the polarity of the two pairs of speakers don't match and therefore require one to have the Plus and Minus reversed?
Doesn't make sense to me, but I can't argue with what my ears are hearing. Any suggestions, comments appreciated!
