The B4 subwoofer

B4 subwoofer

The B4-SUB is an actively driven cardioid subwoofer powered

by a single amplifier channel. It houses two long excursion

neodymium drivers in an integrated cardioid setup: a 15“ driver

in a bass-reflex design facing to the front and a 12” driver in a

two chamber bandpass design radiating to the rear. The cardioid

dispersion pattern resulting from this arrangement unwanted

energy behind the system that greatly reduces the excitation of

the reverberant field at low frequencies and provides the greatest

accuracy of low frequency reproduction. The B4 subwoofer can

only be used in a ground stacked configuration.

The B4-SUB cabinet is constructed from marine plywood and has

an impact and weather resistant paint finish and a pair of handles.

An M20 threaded flange in the top panel accepts the d&b

Loudspeaker stand winder M20. The front of the loudspeaker

cabinet is protected by a rigid metal grill backed by an acoustically

transparent foam. Two runners extend from the rear to the front

panel of the cabinet protecting the bottom panel against scratching.

Two correspondingly shaped recesses are incorporated in the top

panel of each cabinet that accept these runners to prevent cabinet

movement when stacked.

E15X subwoofer

The E15X-SUB is a compact, light weight, high performance

subwoofer for use with d&b E-Series loudspeakers. It employs a

long excursion 15“ neodymium driver in a bass-reflex enclosure.

The built in passive crossover network allows the E15X-SUB to be

connected in parallel to E12 or E12-D loudspeakers on the same

amplifier channel, greatly extending the low frequency headroom

and bandwidth of the systems. As an alternative it can be operated

actively, driven by its own amplifier channel without the need for

any changes to the cabinet. In active mode the E15X-SUB can be

used to supplement any of the E-Series cabinets.

The E15X-SUB cabinet is constructed from marine plywood and

has an impact resistant paint finish, a pair of handles and an M20

threaded flange on the top to accept the d&b Loudspeaker stand

winder M20. The front of the loudspeaker cabinet is protected by

a rigid metal grill backed by an acoustically transparent foam.

Four rubber feet prevent cabinet movement and protect the bottom

panel against scratching. Correspondingly shaped recesses are

incorporated in the top panel of each cabinet to accept these

and to prevent cabinet movement when stacked.
