Slightly larger than the B10, yet still compact, the B15 is every bit as adaptable as its smaller sibling, especially when used with the optional PWB15 passive crossover. The 1 × 15" bass reflex system can be used simply as a passive bass extension or in switchable bi-amp mode in conjunction with TW AUDiO M- and C-series loudspeakers.

The optional PWB15 passive crossover has a satellite output with a switchable high pass filter enabling it to be used with various 8 Ω loudspeakers and one standard amplifier, without the need for additional system controllers.

B15 Format with functionality.
