Review: Axiom Audio DSP EP400 Subwoofer - Small but Deadly
August 2007 By Marshal M. RosenthalRubber feet in place (no need for the included spikes), I push it in a corner out of the way - although the Boston Cherry finish looks good enough to be shown off. I go with the RCA input, rather than using the Balanced XLR connector, and those without a dedicated sub output can use the 5-way binding post connectors (i.e., High Level Input). There’s also a connector for a second subwoofer should you really need your teeth chattering. Axiom suggests setting the sub manually, so I give it a go and find this lets me tweak the sub a bit more intimately than using my amp’s bass management controls. Try it both ways and see which sounds better to you.
There are just two more settings to take care of. The first is the position of the Phase switch. Flip it back and forth a few times and listen to how the other settings respond in comparison (the idea is to get a “smoother” bass response and your ears are the best tools for this); if you don’t hear any difference, then just leave it at zero and forget about it as I did. Then set the Trim based on room size - smaller spaces can benefit from the partially increased frequencies if set to Half or Full, while left at Flat is best suited for larger spaces (Half does it for me). Ignore Load (accessing the internal microprocessor) and Remote since there’s no remote-controlled devices as yet to use with this. And while the USB port is primarily for future software upgrades, Axiom makes a nifty powered light that can be plugged in to make viewing the controls on the back easier when the sub’s placed in a cramped, dark space. Oh and trust me on this, don’t set the bass volume beyond halfway to start.
