You had the 15's in 2.5 cubes a piece, did you not?
With single 4" aeroports?
Tuned to 40hz?
Those speakers will not only fail to operate to anywhere near their full potential installed like that, but will actually DAMAGE themselves in that small an enclosure.
I don't understand how you can keep making these absurd threads, and honestly expecting sincere well-thought responses.
You make threads asking whether or not equipment is any good that you've already purchased, and when nobody responds to the thread, you immediately post up a classified and try to dump it on someone else for more than you ever paid for it.
Why don't you chill the **** out with this incessant circle of impulse purchases and buyers' remorse driven pawn-offs, and give the equipment you already own a half way decent install.
And if you absolutely INSIST on throwing money at your crappy system and driving yourself apeshit around in circles looking for a system that's going to install itself, hit 20hz, 194dB, and look show quality, then you're probably asking the wrong group of people, because i don't know anyone on this board who has a system that actually sounds the way they initially wanted it to without some actual research, and a whole hell of a lot of money, hard work, or both.
