hi
the mid is ATC sm75-150
i have chosen 3500HZ because it is optimal for the mid
and for my taste

Do you have any measurement equipment? If not, you might want to have a look at FRD Consortium for some free tools....
Which Fx and slope?
Hi all,
http://www.scan-speak.dk/datasheet/pdf/d3004-660000.pdf
I will soon develop a big 3-way for a friend of mine, using an 8" eighteensound (16 ohms version) as upper-bass/mid driver:
8NMB420 - High Output MB Neodymium Driver
I wish to use the tweeter as low as possible as to reduce the 8" directivities problems.
At first view I thought 1.4Khz 4th order acoustic should be OK but any input would be appreciated.
😉

Hi, 2khz seems better. This tweeter is not done to support high level below 2khz.
😉
Is this tweeter can fit with a 95db midrange ? Is the tweeter sonically marry the 8" ?
I think it is better to use less expensive driver but in a more linear range (e.g. 5"+1"). The result is almost good.
Have fun.

Hi jerome69,
drivers are still at my friend's home. I selected an 8" because I will use a side-firing 15" woofer, so Fx woofer/mid has to be low (100 to 150Hz max); that's the reason I needed a large cone area for the upper-bass/low-mid range; also I didn't want to build a 4-ways speaker, so no high-mid driver.
That been said I guess ending up with a 91dbs/1 watt/ 1 M global efficiency. Theorically the 6600 should be able to handle 111 dbs at 1600Hz half space with its 0.8mm one way max mechanical excursion. With the slight roll-off begining a bit sooner I thought 1400Hz should be safe enough (100watts)...Distorsions on Zaph's site seem to be low even at this fr...
