MOSFET... i wanted to ask you....
i just noticed your amp ratings for your Midbass....
JL VR series( i read from their site) is capable of 60W RMS and your
driving these with almost the double the power.... (112W RMS).... so is
other speakers... (Kenwood X168 6.5" capable of 50W RMS and driving
them at 90W RMS)
wouldnt this fry your speakers??

Just to elaborate a little more on your question...

I frankly would be perfectly comfortable using a 200 watt RMS amp for my
JL's or my Kenwoods. I remember (like it was yesterday) 16 years ago when I
was buying my first system and asked the salesman that very same question.
I'll never forget what he said: "don't worry, your speakers will cry for
help before they are damaged". In other words, your speakers will begin to
distort BEFORE they reach their breaking point. I am careful NOT to let my
speakers distort because as you correctly pointed out, I COULD destroy those
speakers with the amps that I have connected to them. Of course, this is
not difficult as distortion sounds TERRIBLE and if I hear it I QUICKLY turn
something down.

I purposefully choose a very powerful amp to drive my front midbass
speakers. And no, it was not just about being able to play them really
loud. Having lots of power on tap can give your music dynamic punch (no pun
intended). Even though those speakers are rated at 60 watts RMS, they can
take MUCH more in very short bursts. These short bursts are what can give
your music that extra kick. This is ESPECIALLY true in the midbass region
where you have the snare-drum and the higher harmonics of the bass drum.
Having LOTS of power on tap helps create a much more realistic sound
impression, and I'm not just talking about high volumes, even at moderate
volume levels, these large power reserves can make a difference in the
dynamic nature of your music. It is dynamics, IMHO, not just basic high
SPL's, that separate the good systems from the great systems. REALLY GOOD
DYNAMICS (the difference between loud and quite parts of a song) are what
helps create the impression of a live performance.

I guess what I'm trying to say is that, IMHO, there is no such thing as too
much power. If I were shopping for an amp to power my speakers, I wouldn't
care about the speaker manufacturer's power rating. The exception to this
rule might be with subwoofers, however. It is much more difficult to hear
when subwoofers are distorting (especially if they are in a bandpass type
enclosure). I guess when it comes to subs, I DO make sure my amp power does
not exceed the rated subwoofer power (at least not by much). But with other
speakers, your ears will let you know if you are driving them too hard.
