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.

2. Medium Vented Box

Excellent compromise between bass extension and size. F3 is 42 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. 

For 1508 8 SPS WR:

1. Small Vented Box

Excellent performance of compact, general purpose use. Warm mid-bass response. F3 is 51 Hz.

2. Medium Vented Box

Terrific compromise of bass performance and enclosure size. Warm mid-bass response. F3 is 45 Hz.

3. Large Vented Box 

Big box, big bass! Great as a subwoofer or the bottom end of a large multi-way enclosure design. F3 is 41 Hz.

4. Single Reflex Bandpass enclosure

Special enclosure design that uses the enclosure as an acoustic filter for shaped response. Great choice for a compact 

subwoofer system. Response is 48 Hz – 138 Hz.

5. Sealed Box 

May be preferred for stage monitors to control boominess and low frequency feedback on stage. F3 is 73 Hz.

For 1208 8 SPS WR:

1. Small Vented Box

Very small system with excellent voice range performance. Great choice as the mid-range of a sub/satellite system. F3 is 

79 Hz. Also good for use in a stage monitor.

2. Sealed Box 

Excellent choice for a dedicated mid-bass/mid-range in a multiway system, or stage monitor. F3 is 105Hz.

3. Large Vented Box

Still not all that large, with very usable bass response. Great for a compact, 2-way box. F3 is 61 Hz. 

For 1008 8 HE WR:

1. Small Vented Enclosure

Very small enclosure with super efficiency – works well with a subwoofer.

2. Medium Vented Enclosure

Small system with high efficiency, good voice range and limited bass response – great with a sub.

3. Large Vented Enclosure

Usable bass performance and high efficiency from a compact enclosure – also excellent with a subwoofer.
