Great work and looks fabulous. You may have to consider strengthening the walls, foundation, joists and windows of your home now! What's the story on where and how you acquired the 2nd B460, did you get as good a deal, and what refurbishment did you do, any veneer work? Did you OCD and put the two sequentially numbered 2245H's in and add the sequentially numbered foilcals? Does this mean you have an extra 2245H, plus original foilcal now? One thing I've really learned is I don't like any "music" with these artificially created low bass or tones that seem to be produced. IMO, for car audio systems, and the constant "brrrrrrrppp, brrrrrrrppp" utterrings of that music and systems. There's no musicality, no reality, and no acoustic reason for it other than for the sake of blaring it out to others. Whenever I hear that music in a passing car, I so wish I could remotely force their windows up and push their audio system to at least 3-6db higher with them in the car. I really don't need to hear that crap. IMO, the use of 18" subs in a home environment enhances the low frequencies in a realistic way assuming no major overkill on the low freq EQ if used. The 2245H has an effortless sound to it when driven properly and is plenty for most homes and reasonably large spaces. I suppose if you're listening area is a small auditorium or a large 20 seat home theater you might need more. It would be curious to try some of the 18" Vertec subwoofer drivers in this configuration, especially when considering there are dual 18" rigged subwoofers available in Vertec systems using the 2269G or 225818" Neodynium drivers. The JBL VT4880ADP powered or VT4880 passive subwooferIs there any reason the forum software isn't accepting carriage returns and paragraph breaks? It's condensing my reply into one long paragraph which isn't particularly easy to read. I'm on my home computer using latest Chrome browser. I'll try to edit from my iPhone in few minutes.)
