SUGGESTED ENCLOSURES
For those who want to build their own enclosures but don't want to go through the design process using driver
parameters, Peavey provides the following optimized designs:
For 1808 8 SPS WR:
1. Small Vented Box
Powerful bass performance in a compact enclosure. F3 is 45 Hz.

3. Large Vented Box
Rock solid sub woofer choice for permanent installation or extremely low bass. F3 is 37 Hz.
4. Single Reflex Bandpass
Special enclosure design that uses the enclosure as an acoustic filter for shaped response. Great choice for a compact
sub woofer system. Response is 43 Hz – 120 Hz.

1. Small Vented Box
Excellent performance of compact, general purpose use. Warm mid-bass response. F3 is 51 Hz.
2. Medium Vented Box
