Some may remember I long ago cut down the BatSpeakers
and installed the 15" Dayton Classics with mis-matched plate amps.
Last year one amp quit and I hadn't been happy with the other from the start so left the subs out of the system 'til now.
With all the rain we've had this year I've spent a lot of time listening and thinking...thinking about what to do with the Adcom 545 I picked up cheap as a "Summer amp" but really didn't enjoy listening to. Then...(envision light bulb)
...acquired a cheapo 130Hz Dayton dual coil subwoofer crossover, cut it in half, installed each half in a sub, buttoned up the plate amp hole and installed a terminal.
Figuring there might be a SLIGHT mis-match between the 1.8 Watt 45 Amp and the 150 Watt Adcom ,
I built a level control with a pair of Alpha 10K mono pots and a $4 Radio Shack project box.
Subs are playing nicely with the 4Pis which is especially gratifying 'cause my "pre-amp" is passive; the level controls make the combo work.
A new pair of plate amps would have been $250 and hum is always an issue with them. I spent less than $50 bucks over what I already had in the Adcom and parts drawer RCAs, etc.
Let it rain. Well...not really...I do hate having that 150MM travel bike parked so many days
but it's great getting all the notes down to 27Hz or so.
