PSI-8
subwoofers are available directly on our website with ratings of 400 or 600 watts rms power handling.They are built with high quality 2″ dual voice coils(flatwound in the high performance version), stitched 3 mm interwoven leadwires, 10gauge direct connect leads, 8″ pulp cone with wide roll rubber surround, and rubber mounting gasket.

The versions offered on our website are designed to be used in daily systems where good sound quality and high outputis required. The PSI-8 offers excellent sound quality and can provide exceptional levels of output considering its small size.

PSI-8 subwoofers are also available to be custom built with power ratings from 250-750 watts rms in varying applications from sealed, to ported, infinite baffle, or bandpass in daily systems or for competition systems.

The PSI-8 is designed to use a choice parts selection that offers an incredibly strong, long throw design with exceptional power handling. Other 8″ subwoofers do not offer the same combination of stroke and power handling that the PSI-8 does.

In terms of output, reliability, and quality, these small subwoofers can be compared to subwoofers in a much higher price range. They offer top quality components, adhesives, and assembly. This series sells at roughly the same cost as many imported, low quality subwoofers with weaker, smaller internal parts. Do not be misled by the price; the PSI-8 series subwoofers offer outstanding performance at an extreme value. These are hand assembled at our shop in the USA.

Standard features include:
Dual stacked 6″ x 1″ Y35 ceramic slugs
Chrome top and bottom plates
FEA optimized motor assembly
6 spoke aluminum cast frame – Black
10ga CCA direct connect
Standard 4 layer aluminum roundwire voice coil
Dual 2 and Dual 4 ohm standard impedances
Dual 6.5″  linear roll poly-cotton spiders

Kevlar impregnated pulp cone body
1.1″ wide roll rubber surround
6″ polypropylene dome dustcap
