Wow, Thanks for the graphs. Is the sensitivity in db/w or at 2.83v?

Good question... i didn't run these, a friend with LMS did. If i had to guess i'd say 2.83 V (so dB/2W)

Something like the Fostex Heil above? What are you thinking of for mid-bass? Active or passive?

I bought 4 Klipsch 1089-av 10" mid-woofs that klipsch uses in the RF-7 and run up to 2200Hz. They are good for 96 db at 1 watt and use 90 oz magnets with ceramic-aluminum cones. I am thinking of placing one on the front and rear in a bipolar arrangement for baffle step correction, and using a 1st order series crossover of the proper Z to get a 12db/octave rolloff around 1000Hz. Hope to get pretty efficient speakers and good sound. I heard the woofers in the RF-7 and they are pretty darned good. Klipsch tries to run them too high and I don't like the sound of the Klipsch tweeter as much as I will like the Heil. This two way should be extremely transparent. I'll have to spend time tinkering with the crossover but that is always the case.
Any comments or suggestions are appreciated.

Those are pretty woofers, haven't heard them. have heard comments that maybe Klipch is a little optimiistic with efficiency. Will be very interesting...

at a 1k XO you may need to be a bit steeper than 2nd order.

Default Tweeters?

Hi, Dave!

Any good (super)tweeters in stock?
I have seen the Ess AMT/Heil on ebay:
http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WDVW
(are they the "real" thing?)
Do you have anything like them, or Raven, or suggestions?

Some relatively good budget ones... another set of the Coral alnicos coming up (if they test fine)

That looks like new from the ESS factory... they have bumped the price abit, but i figure they are still VERY good value.

These go really low for a super-tweeter (i've heard of people getting as low as 700-800 hz)

Nothing used, and so far i've only picked up a single new driver for resale -- the CSS WR125. I am a Solen dealer, so can special order any of the drivers they sell (mostly Fostex to this point)

I have a pr of the Arum Cantus 2Gsi i picked up from Bob at CSS. I figure these are probably best value for a ribbon SuperT. At this point i'm likely to mate them with a pr of Jordan JX150 i have (active XO at 6-8k)
