Axiom EP400 subwoofer
The Epicenter EP400 by Axiom is intended to bring the strength of a home theater subwoofer to smaller environments. While only 10.5 inches wide and 13.8 inches tall, the 400 still packs 500W to produce up to 116dB of sound, and can span frequencies between 23 and 150Hz. Axiom has further equipped the subwoofer with "intelligent" DSP, capable of matching driver response to an exact frequency at any point along the supported spectrum. The driver itself is aluminum and eight inches long, and has a maximum variance of no more than 1.5dB. The 400 is being sold in beech, cherry maple and black oak finishes, for $1,100.
