"Old-school" bass

The BRX840 8" subwoofer sports a reinforced high-density paper cone that lays down warm, "old school" bass that'll have your vehicle rocking. The double-stitched surround helps this sub handle up to 250 watts RMS, so you can feed it plenty of power. Just add an amp and an enclosure, and you've got the makings of a real bass party.

Product Research

Features

Woofer Terminals: The woofer has spring post wire terminals. They will accommodate bare speaker wire up to 10 gauge.

Sealed Enclosures: Sealed enclosures provide the most control over a woofer and provide accurate sonic reproduction, making them suitable to all types of music. Memphis Audio recommends a sealed enclosure of 0.6 ft.

Vented Enclosures: Vented (or ported) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power. Memphis Audio recommends a ported enclosure of 1.0 ft³ with a 9" x 1" x 12-1/2" slot port, yielding a tuning frequency of 40 Hz.

Q
Box type recomended?
[ Douglas  Jun 21, 2019 ]

A
It will work in either a sealed or ported box - but it needs a relatively small one. The recommended airspace for a sealed box is 0.6 cubic feet and 1.0 cubic feet for ported. The ported will likely give you more bass output (especially with less power) whereas the sealed will give you tighter, more controlled bass. We don't currently sell a prefabricated box that would be suitable for that sub.
