There are quite a few plate amps at MCM. I put one in a homemade Madisound sub relegated to outdoor duty.
a rumored Allison subwoofer! found and bought now need plate amps ! suggestions please ?
howdy ! in my quest for a different fix for a vintage superlative sub i found and bought TWO of the uber rare Vintage Allison push pull passive subs !
i now own two!
need a electronic subwoofer now ! ( or two ! )
the sealed cabinet is pretty good sounding sub ! quite clear and went clean down to 20Hz as per Roy Allison ! ( no doubt w/ the electronic subwoofer! giving assist ! )
local pick up had to hire a guy on CL to go get them fr seller.
seller ? he refused to ship them tho he has audio business! OK VERY strange ! hopefully they arrive whole and undamaged ! shall i have him ship them w/ the grilles on ? I think so!
An Allison ex-employee had told me : "There was also a really terrific double push-pull passive sealed sub ,same driver as ALl130" oh ?
so yes! we found some ! need some plate amps now ! any suggestions ?
here it is !
turns out they even made 18" version as a commercial product SO
we would consider measuring and upscaling these to 12" ( or larger ) so we can find / use some servo sub drivers!
If you are wondering why ?
the push pull meant 20% less harmonic distortion one was electricly backward but acoustically in phase
These were reviewed in Stereo magazine many moons ago by the infamous Julian Hirsch !
