Have fun with the speakers, Scott! From my experiments, I offer these three recommendations:

Full range open baffle. I can never go back to boxes.

Heil AMT tweeters. Spendy, but worth it.

Dayton RS series drivers. Like the poly/foil caps, superb quality at affordable prices.

IMHO, nothing else comes close. YMMV.

thanks
Paul-it's 11.25PM but the beer's still good and the music is great.
PS: Isn't bloody amazing;you're in Iceland and I'm in Australia and some fools want to control the internet.When I was younger you would have had to be a penpal-weeks between replies.

It is amazing Cheers to Australia. There's always something that Icelanders recognise in the general mood in South Africa, Holland and Australia. Funny stuff.

And re. the speakers - yup, I agree, the 15 Ohm load won't break anything, it looks like. But you'll get some high-frequency peaking, which will be noticeable. So you'd have to adjust the output filter or do some EQ-ing. And you'll get less power out into such a high impedance of course.

Look at these Wurth coils:

20 Ampere high permeability.
They are pricey but worth a try I think.

does anyone know what is the difference between this amp and the other 2*100w from sure. the one that looks like the 4*100w?

I think they made a mistake and used the wrong picture.

They take the 4*100 board and use only 2 channels.

[ddashk]

they have two different 2* 100w amps on the website. i got the one which looks like the 4*100w but i ordered the other one. the one which now comes with a fan. my question is how much of a difference is there? al the reviews i have read are on the 2*100w with the fan. is the one that looks lie the 4* 100w worse in sound quality?

The 4 channel amp is worse in reliability because the heat sink doesn't contact the chips well and the dc off set adjustment circuit doesn't give enough range of adjustment without a mod to jump some resistors. I would rather have the other, 2 channel board without the crazy piggyback output board but it looks like Sure is determined to get rid of the 4 channel boards. If the dc can't be adjusted to less than 5mv per leg, tell Sure you demand the other board.

I wasn't aware that Sure was using their 4* 100w boards for the 2* 100w boards, thanks for that info.

[ddashk]

they still have to 2*100w which has its own board but also the one based on the 48100w

does anyone if there is a difference in sound. the heatsinks and insulation on mine are perfect so i won't sent it back and deal with all that hassle unless the normal one sounds nicer. has anyone compared the two?
