I'd like to know the specs too.About 120 pounds. Twin dB12 Plus drivers, downward firing. Three 4" flared vents. 850 watts continuous power from the Indigo BASH amp.
Stock tune with all ports open will be 25 Hz. Tune options will be 20 Hz and 16 Hz. To lower the tune to 20 Hz, simply plug a port and alter the SS filter/EQ switch to the 20 Hz setting. Ditto for the 16 hz tune, except it will require plugging two ports. Each SS filter/EQ switch setting is assigned a specific EQ curve, designed to work either with all three ports open, one port plugged, or two ports plugged, respectively.
I would imagine the most popular tune for the PB2+ will be the stock 25 Hz tune, or the 20 Hz tune with one port plugged. If you really want a 16 Hz tune all the time, you would have been better off with the 16-46 PC+ in the first place.
However, there comes a time when you just have to say...we might have enough subwoofers.Tom, I think you're quickly approaching the point of saturation. You've already got so many subs that I can hardly tell what the differences are between various models. At some point your potential customers will have so many choices that many will suffer from "analysis paralysis" and will be incapable of making any decision. I imagine you'll begin to receive so many "what subwoofer should I buy" emails that you'll find it hard to keep up.
I guess there are worse problems for a business to have though!
