    0.60 cubic feet7.080"7 5/64"3.4"
    ** Tailor this to your needs. For ported enclosures add ~20% volume and tune accordingly *** Speakers with vented pole need at least 1" clearance for cooling

    For those wanting to use the LP8.0 as a subwoofer; we offer them as single drivers in either 4 or 8 ohm. The woofer is exactly the same woofer you would buy in the LP8.0C component set.

    The LP8.0 has an Fs of 29Hz and a usable frequency response of 20Hz to 4kHz. We recommend a minimum of .65³ feet for sealed applications. Moving to 1.25³ feet will improve output and further smooth the enclosures response curve.

    All Linear Power™ woofers can be used in sealed or ported enclosures. Ported enclosures need to have 20% more air space plus the port. This can be adjusted based on your needs.

    All Linear Power™ woofers have a bumped backplate and an extended pole piece. The "bump" allows more room for voicecoil travel. The extended pole piece improves magnetic force and reduces distortion when the motor assembly nears the limit of linear exursion.

    The additional material adds more heat sink for the voicecoil. The backplate and pole are one piece which provides better heat transfer than cheaper two piece units. Even the black paint is designed to improve heat transfer. The LP65© pole piece has a 5/8" vent in the center to move enough air to cool the voicecoil.

    Like all Linear Power™ woofers the LP8 has an inner dustcap to seal the voicecoil hole. The Rubatex gasket ensures a positive seal for those wanting to mount the woofer from the front.

    A butyl surround guarantees you won't ever have to worry about it rotting away. The outer dustcap is rigid and sized so that it becomes a structural element to provide strength to the speaker cone.

    A push button terminal allows easy hookup while keeping a strong connection to your speaker wire. Easily accepts up to 8 awg wire.
