Don't get me wrong -- that is my preference too... the amp of my dreams (still working towards it, will have 4 - 8 W so efficiency is important to me, and the simpler the path before the amp, the better.

Simple has its benefits. I'm building a Son of Zen, which probably says it all, though I wouldn't want to try using it for every speaker or application. In answer to your question regarding integration, it depends on the drivers respective efficiencies, roll-off characteristics, optimum crossover points and a host of other factors all of which need to be considered. Hense something like the 15" Hawthorn might be a good bet as it removes that worry. As a bonus, like the legendary Tannoy Dual Concentric drivers, it's a co-ax, so imaging, time-alignment and phase should all be first rate.

That SI amp. It'll need tweaking as they cut out pretty quickly under 100Hz as I recall. I think TNT-Audio have a guide to modifying these things, and Hifi World ran an article a few months back. I'm not a fan of either of these in all honesty, but in this case it might be useful.

The most comprehensive guides are actually right here on this forum.

Also, I would just like to add that the SI amp seems to be quite capable all the way down to at least 20Hz, not 100Hz.

The reason I say this is because I just installed a pair of Aura Pro Bass Shakers on the siedes of my couch and I'm powering them with that SI amp. (not very loud of course, but it doesn't need to be either)

I played a couple pipe organ CD's that I know very well and that have true bass down to 16Hz, and I could definately feel all of it.

Now we're going to watch a movie with them.

I believe it. Proves how much attention I pay to amps doesn't it?

If that thing can now hit 20Hz, then they must have changed it. So much the better. it saves getting the soldering iron out and removing a resistor.

Even without mods it can hit 20 Hz, but not flat to 20. The input caps are too small. Chops is using it bass only so has no reference to the higher frequencies.

Speaking of which, we watched "The Italian Job" last night with the SI amp powering those bass shakers. It actually does quite an impressive job. We really like the part towards the end when they blasted that armored truck through the street.

With the sub pounding away and those shakers "shaking" my hiney, it was pretty neat.

Anyway, I think I'm starting to vear off topic. OOPS!
