Well the bigger enclosure does mean better efficiency for the power supply however those BASH amps can be finicky if the impedance does not match up well with the driver. In demanding passages impedance moves all over the place and the risk of overheating and clipping becomes a serious issue at high SPLs. Those cheap BASH amps which lack dynamic headroom, can't touch the performance of Axiom's DSP controlled amps which are designed in house by Tom and Ian.

While most people will fawn over the drivers or enclosure, its the hidden electronics and amp which are just if not more important. That's what makes these small EP400s with 8" drivers perform so well. Everyone who has heard them at my house has said the same thing, "I can't believe the bass from that small box!"
