Cam - I know what you mean, it could be a little nerve-racking with all your amplifier eggs in one basket (so to speak). I personally run a pair of the passive 15-3's with passive 18 subs bi-amped with LX3000's and a DSP-244 processor (thank God for employee discounts!). Really I only do it this way because I am brain damaged...well, maybe I just like it really, really, really really LOUD!
That being said, in my 5 years with the company I have never seen nor heard of a Powersub 315 failing. I just looked through our system and every single return authorization that we have issued in the U.S. was due to damage that occurred during shipment. The added voice coil tracking protection circuits make it virtually imposssible to blow the woofer and the amp module itself has the same protection package as Dynacord outboard amplifiers have (Audio Limiters, High Temperature, DC, HF, Back-EMF, Peak current Limiters Inrush Current Limiters, and Turn-On delay). I would not hesitate to use this sub myself each and every day...it is more than adequate for the additional satellite speakers as well.
Now as far as the D12 vs. the D12-3, it is all a matter of personal taste. I personally prefer the smoother midrange of the 3-way vs. the "crispy" high end of the 2-way. You really can't go wrong either way, but the 3-way box coupled with the sub will give you a true 4-way system which in turn allows each transducer to work a little easier reproducing a smaller portion of the frequency spectrum.
Just buy it...you'll dig it!
Mike,
I will say that I can tell a very noticeable difference with my D12-3 tops. The true 4-way system sure brings out parts of the music I have never heard before. Did you know that they use cowbells in so many songs? I would have never guessed until I had heard it for myself! Another testament to the Dynacord for being a supreme system!!!
SOLD! I always need more cowbell!

Steve, you are right in the sense that you do not have individual level control for each transducer, however there is still a crossover (either active or passive) in the signal path between each driver, therefore reducing the workload each is asked to support.
Call it "Quasi", "Pseudo", "Semi", or anything you'd like...bottom line is I would put it up against any system on the market at this price point.
Steve, with my two active tops and one active sub, I have a three-way system. Each driver is being powered by a separate amp and crossed over at a predetermined frequency. In my system it breaks down like this: below 100Hz to the sub, 100-1800Hz to the 12" woofer in the 2-way box and above 1800Hz to the horn. I have the option of setting my sub-woofer crossover frequency to 80 or 100 or 120Hz. That's uning a pair of FBT 4a's and an RCF 705AS sub.
If I add the 18" RCF 8001AS sub, then I can set it to take everything below 80Hz, send 80-120Hz to the 705AS, leaving 120-1800Hz going to the woofer in the 4a and 1800Hz and up to the horn. I would then have a 4-way system!
Why are we debating crossovers, amps, passive v active, and everything else that has nothing to do with Keith's thoughts on a new sound system?
