As most of us know, unless cutoff is up around 400hz small drivers have difficulty with 87db+ from experience. Here's an excellent Forum discussion concerning this!

Default Dayton PS220

Alpairs, especially Dave's modded versions are a very nice choice. Very refined.
An interesting alternative is the Dayton PS220... requires a fair amount of fine-tuning and eq'ing but once that's done it is a superlative driver with astonishing impact. When properly eq'd it has a lot of refinement as well. Have a look at what I've done with my TimePulse Lambda speaker using this driver. (On my website, ref'd below). This one WILL play loud (and clean) if and when it is required to do so.

BTW, PartsExpress ships to Canada also.

One of these days I'll get around to having Dave mod a pair of these for me, I think it would really be a great option.

By far the best way to get PE stiff into Canada is to order it from Bob @ CreativeSound

On an OB with no load maybe. Other than electronics failures (a pair of FE126 & FE127, and an FF85k) i have not killed any FR in use.

I have given up (actually i have one more build to try) on OB so it is not an issue. I like to keep XOs <350 Hz, lower if the rest of the design suits.

actually your personal responsibility there is less than the quantity listed

does the builder have your drawings yet, or is it still brewing along with your morning Turkish?

No drawings at all -- still just in my head. This is one Bernie & i discussed building in cedar to use up 4 of those lovely 10" dipole woofers we have (the other 4 i want to put into Demetri's system -- that will likely be a low rectangular H-Frame)

I'm guessing that for some examples, 2 is a sufficient number. I suppose 1 is the minimum when not adequately supervised

if other audiophools present in the room qualifies as "supervision", then it's still no guarantee (or perhaps it's an excuse ) poor gentleman will not live that down for a while yet

As far as im aware, Solen and CSS are the only places to purchase these speakers, if others options are out there, im all ears. I would prefer to buy from a Canadian company however.
The two drivers ive been looking at are the Fostex 206EN and the Alpair 12P. But I'm open to just about anything that fits the bill.

Thank you,

The best advise is to let your ears be the judge. Your the only and final person who has to live with the drivers you buy. The Alpair is more of a 6 inch I was told with a big cast frame? The fostex's hummm? The older fe206e has a peakness problem I don't know about the new one. Heres a idea? I saw these on audiogon? Its fostexs top of the line 8 inch fullrange drivers for sale Half the price.I meet a guy at the A.K. fest in march that bought these drivers new. He told me he had dave from planet 10 do his mods to the drivers because he wanted the best out of his drivers he told me and he really enjoys them. Here is a link cheers.jm
