Need speakers that can rock with just one watt? You found da place.

Re: Karlson-coupler aspect - what might be juggled for aspect & performance?

hi GM - very nice program (WinISD won't work for me anymore and AJ seems to not have series BP capability) - IIRC, that particular coupler above exhibited a bit of rise and its curved reflector made for rougher graph with mic at ground perspective than another coupler variant wihc was ~32" tall (and around 190Hz 3rd Z peak - - from these programs it appears tuning F would be described a bit lower than that Z peak)

re:"extra" chamber - are you referring to the partitioning of K's back chamber with the rear lowpass shelf?


re: 1/4 wave damping - lets say one wants the front tuned in 120-135Hz range --- what might be the effective height of the slotted coupler and what might be practical crossectional area vs Sd? - it has some building constaints.

re:"BP"-ha- CN wouldn't like that :^)

these things could/can be made to perform pretty well.

Best,
FI
