Enclosure: RBS-1

2 x Black Widow 15" Subs.

500/800 rating at 4 Ohms.

RBS 1 can be used as a subwoofer (40 - 200 Hz) in P.A. situations;

it is equally well suited to be used as the low end

portion of a bi-amp system for electric

bass.

The RBS-1 is a unique, low

frequency enclosure which combines

the best features of current vented box

and closed box technology-

The enclosure is constructed of sturdy

plywood and covered with Peavey’s

rugged carpet/tolex® material. Black,

steel handles and corners are used for

ease of transport and enclosure

protection.

The enclosure creates

sound by way of two 15" BW speakers,

each of which is side loaded into a

compression chamber and an

optimally tuned resonant volume.

The compression chamber limits extreme low end speaker excursion while the resonant volume limits excursion at higher frequencies and enhances low

end response.

The advantages of this

configuration include lowered

distortion, enhanced SPL at prominent

bass frequencies, compact size and

speaker protection.
