Have any of you heard of this cabinet? I went to hartke's site and saw it, it seems like a realtively nice cabinet, as I like the intimate tone of 15"'s and the clear yet punchy sound of 8"'s. It says it's rated at 8Ohms, which is the downfall of the cab. However, where I've seen it listed at, it's only listed as selling for $350, which sounds quite odd to me. Any thoughts?
