FOR 1508-8 alcp:
1. Small vented enclosure
Excellent performance for compact, general purpose use. Warm mid-bass response. F 3 is 50 Hz.
2. Medium vented enclosure
Terrific compromise of bass performance and enclosure size. Warm mid-bass response. F 3 is 44 Hz.
3. Large vented enclosure
Big box, big bass! Great as a subwoofer or the bottom end of a large multi-way enclosure design. F 3
is 40 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 47 Hz – 135 Hz.
FOR 1508-8cucp:
1. Small vented enclosure
A small enclosure with outstanding bass performance for its size an F 3 is 61 Hz.
2. Medium vented enclosure
Small box with powerful bass and predictable, flat response down to an F 3 of 50 Hz.
3. Large vented enclosure
Strong, flat reponse with bass extension to an F 3 of 45 Hz. Deep, predictable bass quality for great
subwoofer and multi-way system performance.

The 1508-8 alcp driver is an excellent
choice for general purpose sound

reasonable and its performance from sub-
bass to upper mid-range is strong. Its
versatility includes vented and bandpass
enclosure designs.
The 1508-8 cucp is specifically optimized
for amazing bass performance in very
small vented enclosures, along with flat
mid-bass and mid-range response for an
accurate, clean sound quality. It is an
excellent choice for compact enclosures,
multi-driver subwoofers and monitors
where enclosure size is limited.
Pro Riders can work with crossover
points as high as 2.0 kHz, but work best
below 1.5 kHz. They deliver excellent
performance in both woofer and
subwoofer applications.
