In reply to:
Is there any other sub that is comparable to the EP500? I'd like to consider all the options.
Of course there is . You might check out the
SVS PB12 Ultra, the
SVS PB12 Plus/2, the brand new HSU VTF-3 HO Turbo (I can't find it on their web site. I believe there is a slight delay while a minor driver problem is addressed), the
Rocket UFW-12, or the beautiful
ACI Titan XL. All are competent subwoofers, and each has advantages and disadvantages relative to the others. I happen to prefer the EP500 because of the DSP technology, it's linear frequency response, and it's relatively compact, unobtrusive footprint. YMMV.
