Thanks Cal,
I can't stress enough how good these woofers are for the money. Worth grabbing a couple to experiment with (not you Cal, heaven knows you have enough BIG driver already ).

Hi Cal,

Thanks for the link. The 12 in woofer has a Qts of 0.75 so better fit for OB this is probably why the review say that the woofer has no bass.

At an efficiency of 95db i would be better off with my FE206E and these are free since I already have them

BTW, I'm not tired of your idea I appreciate them.

I have surfed quite a bit today and it's amazing that there is barely NO info about DIY with pro drivers. Maybe I haven't search enough...

Regards,
Eric

How do you have everything crossed over? How high do you suppose that 15 could be crossed without issue? What ohm are they? A pair of these push-push under each of my 901's would help where they leave off.

These are actively driven - the crossover points are 350Hz and 3000Hz. I wouldn't cross this woofer much higher, maybe 500 - 600. They are 8 ohm nominal.

Sweet. It is tri-amped or just bi-amped? I noticed they call this a woofer and not a sub-woofer. How much power are you feeding them? Are they as efficient as the mid and tweeter? Your enclosure is sealed and roughly 3 cu.ft. internally? What are you using to actively cross it all over with? Thanks for the info.

Tri amped. 3 LM3886 chipamps on active filter boards. These boards have level controls, to adjust the power output. The power output to the woofer is ~70watts, the mid is turned down to 50% (that driver is VERY efficient) and the tweeter is at about 70%.

The enclosure is small for a driver with these specs (high Q). The idea was to make these acoustic suspension, driving the alpha up to smooth the frequency response. Works very well for this driver as it has great parameters for acoustic suspension. Excellent power handling.

My home brew triple plate amp:

Would be ok to have just a bit higher sensitivity on woofer than on mid, due to BSC issues
Its also ok to pad down a mid
But 95db is a realistic target

You could use your Fostex, but Im sure your son will toast them very quickly

Fore your purpos it would be ok to use adjustable L-pads, but they cost money too

That is RRP, and who pays that? You're going to be hard pressed to DIY anything better than a well haggled deal on these.
