A little off topic, maybe, but maybe not too far.
When I built my vertical stack of three 12" servos per side to supplement my LS-9's (fan-TAS-tic speakers, BTW), I put them into separate cabinets and bolted the cabinets together. I did it that way mainly to save my back. Them suckers is heavy! All the woofers are facing out at the moment, but it would be fairly easy to rotate the middle one (say) to the rear and do a little rewiring to keep the proper phase alignment. The question is: would it be worth it? Theoretically, this arrangement should reduce 2nd harmonic distortion. But I would love to hear from someone who has tried it both ways. I saw Danny (Hi, Danny) at RMAF but forgot to ask him this question. OTOH it would be good to get input from some of you as well.
Thanks.
