About the Edge EDBX12ADSP-E3
From our tech experts at CEN
An Edge 12 inch subwoofer in an active sealed bass box, with the amplifier built in, 400w RMS.
Who it suits
Drivers who want bass without building a system around it. An active box means one unit, one power feed and no separate amplifier to hide.
Our tech experts advise
It still needs a fused feed from the battery and a signal source. Secure the enclosure properly: an unrestrained box is dangerous in a crash. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: How is the EDBX12ADSP-E3 tuned?
A: Through a smartphone app, which gives control over the 8 band parametric EQ, subsonic filter, low pass filter, phase and time delay. A remote bass level control is also listed in the features.
Q: How big is the EDBX12ADSP-E3?
A: It measures 375 x 500 x 298mm (H x W x D). Check this against your boot space before ordering.
