250-350 per side would be a good amount of headroom for the LS. I used to use the 300's, but we were actively biamping the industrial LS, double stacked.

You sure don't want to try rocking with 100 watts per channel. first few clips and it would all be over. Worst thing you can do is have too little power and let the amp go into distortion. That's what blows up drivers, NOT having too much power.

I'd do the K2, as you get bigger, the $/watt is much less and the amp tends to never overheat. Just do it.

I hate to say it, but the Tapco J1400 is a pretty well performing amp & I've found it to sound good where I've encountered them. For this use, you definitely want to avoid clippingaabove almost all else. What crossovers are in the Las? Higher order networks would be a good idea IMO. 24dB or higher. Multiamping really starts to make sense in these scenarios, I think.

Btw, the K2 is a great amp for playing back recorded music....and is a

workhorse in the PA realm. Heck, they're even used in the studio [;)]

Btw, every doubling of power results in a 3dB increase in volume. So a

200 watt amp would only go 3dB past the "rating" on the lascalas. Btw,

that is a thermal rating...which means it can only handle no more than

100 watts for like 10 hours straight or watever the test measures. You

could probably get away with 500 and 1000 watt spikes (like with a kick

drum) and not have unbearable clipping or distortion. I wouldn't

suggest doing this, but you might be surprised how quickly a kick/bass

guitar will use up watts.

In your room you'll probably be running at around 25 watts if you like

it loud....you can expect the kick to be a good 10dB louder than

everything else at the lower frequencies which will have you pushing a

good 250 watts. If you clip your amp at these levels you'll fry the

speakers, but your speakers should be able to handle a non-clipping amp

at these levels no problem.

I agree with Indy. Go with a small Mackie like a 1202VLZ. More than enough for what you need. Reliable. Impeccably quite preamps, and no one is going to hear the "tube difference" in this sort of application. You can pick up a used 1202VLZ on ebay for a song. I have two. Might even be willing to let go of one.

My room is about 25' by 25'. We have acoustic (egg crate) treatment on the ceiling and front and back walls for sound reflection.

Surely you're kidding. NOT EGG CRATES! I sure hope you're just referring to the "design" surface. Egg cartons are one of the worse acoustical treatments you could possibly apply. And the rubber floor ain't far behind!

seem to have a very smooth frequency response with a controlled dispersion

Whoa ....Who ....!

it seems you have never seen the Frequency Plot for the 'Scala .....

talk about Spikes ......[:^)]

No I haven't actually....but it can't be much worse than other PA speakers, or is it? I know Colter has a bunch of those old frequency response plots for cornwalls and fortes and I bet he has one for lascalas. Going back there this weekend so I'll give them a look.

Btw, raw frequency response isn't everything...resonations are a big concern too (in fact, probably a bigger one).

Hey guys, I have been peekin around ebay and there seems to be some good mackie powered mixers. Would it be much of a compromise to buy a Mackie powered mixer oppose to the Mackie 1202 and than a Crown? Thanks, GUy

YES, HUGE COMPROMISE...but go ahead and buy it if your heart is set...

or just get the 1202 and a crown and be done with it
