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 1508-4/8sps:
1. Small Vented Box
Excellent performance of compact, general purpose use. Warm mid-bass response.
F3 is 51Hz
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 73Hz
For 1508-8cu:
1. Small Vented Box
An incredibly small enclosure with outstanding bass performance for its size. F3 is 53 Hz
2. Medium Vented Box
Small box with powerful bass and predictable, flat response down to an F3 is 45 Hz
3. Large Vented Box
Strong, flat response with bass extension to an F3 is 41 Hz. Deep, predictable bass quality for great subwoofer and multi-
way system performance.
For 1508-8he:
1. Small Vented Box
Small box, big voice. Very high efficiency and good bass performance in a small enclosure.
F3 is 60 Hz
2. Medium Vented Box
Super-high efficiency in a popular enclosure size. F3 is 55 Hz. Great choice for use in a full range system.
3. Large Vented Box
Big and loud! Super efficiency and strong bass performance to an F3 is 50 Hz. However, for subwoofer only use the sps
and cu versions which are better performers.
For 1208-4/8sps:
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.
