Axiom EP500 Subwoofer Introduction
This is a review of the Axiom EP500 500 watt powered subwoofer featuring an aluminum 12" driver in a ported enclosure.
If you haven't heard of Axiom Audio by now, you're probably not in touch with the home theater scene as much as you think or you don't spend a lot of time online researching products (perhaps a little of both).
Axiom Audio's loudspeaker design philosophies adhere to their rigid scientific measurement standards and the psychoacoustical testing protocols of the National Research Council (NRC). Axiom's founder, Ian Colquhoun, is a firm believer of the principles established by the NRC and is dedicated to adhering to these principles in all Axiom loudspeaker products.
The goal of the NRC Research, is to have manufacturers adhere to loudspeaker design practices that measure with a flat on-axis response and with an even but constantly declining (or tilting) polar response. The polar response curve is the summed and weighted average of many curves taken from either a 180 degree or 360 degree family of curves which are usually either at 10 degree or 15 degree increments through the entire measurement range.
Last fall when Axiom Audio invited us all the way to Canada to take a factory tour, I had no idea they had a couple aces in their sleeve with their new DSP driven EP500 and EP600 subwoofers. We walked away from the tour with a very positive first look into the capabilities of these new super subs. In fact, based on the performance measurements we conducted and our extensive listening tests, we awarded the EP500 our 2004 Product of the Year for the subwoofer category. Despite our very positive experiences with these subwoofers during our tour, being the Audioholics we are, we thirsted to learn how they would perform in the most critical of listening environments – our own sound labs. With that, we requested review samples of the EP600 (review forthcoming) and EP500 (my personal favorite, mostly due to its more compact size). These subs dazzled us at the Colquhoun labs, but did they do the same in our own?
