IB upgrade

My tempests went belly-up. Maybe because they were being over-driven, but I never heard the "you'll know when you hear!" sounds of impending doom.

One thing would be to replace them with 4x15s instead of the pair of them. Thing about that- my manifold location- the proper location of being centered and in the front of the room- is limited for room. For me to crawl past the speakers, I would have to move it to a non-ideal location.

So, the other option is to go bigger. I like the sound of that. Using a spreadsheet listed on the Cult's website, there is a rating of cost-per-liter of air. I'm leaning towards the Ficaraudio.com Q18s, because the winner- the Chinese-made Mach5s are still unproven (and not much better priced).
