PEAVEY PRECISION TRANSDUCER SP1, 100W/150W RMS 104dB 1W/1m
The old stuff as it does more!
Contact me if you want the technical documentation.
This material is currently rare, if you are in good condition with the HPs of origin:
15 "Peavey 1504-4 Black Window and Driver Peavey 22XT or 22A, please, it's great background music for an external event (but for big arms (68Kg/pièce, casters must!)
Leaner the SP3 the same type are also interesting 103.5 db 1W/1m.
Equalizer necessary to correct a hole in the middle of the band, but for purists, of course.
