Our take on the Sound Ordnance™ B-8PT

by Dominic Devito
Sound Ordnance

Who needs a powered subwoofer?

To produce bass, you need a sub, an enclosure, and an amplifier, and it can be little tricky to match them all up. A powered sub eliminates all the hassle, as the manufacturer designs the enclosure to house the sub and amp together. This all-in-one solution is especially useful in smaller vehicles, where there's no room to mount a separate amp, or in any vehicle where you need every bit of cargo space. Powered subs range from small, flat boxes that fit under your seat to larger boxes that go in your trunk.

The Sound Ordnance B-8PT powered subwoofer turns the hard-to-fit spots in your vehicle into potent bass bastions, adding warmth and punch to your favorite music. You can fit this compact low-frequency factory under your car seat or in an out-of-the-way location in the cab of your truck. Preamp- and speaker-level inputs allow convenient connection to just about any system, plus you can tweak the phase control, bass boost, and low-pass crossover for maximum firepower in your vehicle. A wired remote lets you take command of your bass from the driver's seat.

The B-8PT's built-in amplifier sends 120 watts RMS to the 8" subwoofer, adding high-impact low notes that'll fortify your music. The Sound Ordnance logo means you'll get more than tremendous value and reliable performance — the B-8PT is reinforced with a 3-year warranty so you can add it to your system with confidence.

Comment by Robert Ferency-Viars Staff Writer - Creative,

Added much-needed bass to my daily commute!

Written by Robert Ferency-Viars, Staff Writer - Creative, on 12/21/2011 12:41:00 PM

I recently added the Sound Ordnance B-8PT powered sub to the back of my car, a Nissan Versa, and I'm very happy with it. It's just the right amount of bass for me, and I immediately started hearing notes that I'd never heard in my car before. If I turn up the sub, it booms really well - it's not shy! But I like my bass tighter and more focused, so I have the gain set about midway to keep it under control. It's great! The remote control knob lets me turn it down when my sons are in the car, so they don't have to put up with the pounding bass.
