Well that is something to be figured out.. Any ideas..
This is what i thought i'll do..
but now i am a bit sceptic about the ports at the bottom.
So might move them to somewhere along the middle of teh length of the tube and put a granite slab base for mounting the unit...
Still thinking...

any suggestions..?

Thanx for the links. Yup, I had read these before, just did'nt remember them by name. The state variable is a little complicated & I'm not sure I want variable filters. I've been trying out different values for the baffle diffraction & have the various pairs of resistors in hand for testing.

Regarding the crossover freq. from woofer to mid, I want all the baffle diffraction correction to happen in one unit, the mid, rather than spread it over the woofer as well. Right now the diffraction is spread from around 210hz to just above 3000. The crossover for the woofer to mid is 200hz & mid to tweeter is 3100hz.

BTW I'm using BB2134 for the opamps. Guess what NE5532's are available in SP road for Rs. 15/- a piece.

I will drop in some day to listen to them..

Can some one suggest a compound(may be rubber based and inexpensive) that i can use to coat the inside of these enclosures to deaden it. It should be pretty safe, both to me and the drivers.

Thanks
ajju.
