Hi guys
I'm planning on building another pair of Cornus. Gave away the little 8" ones to a friend. The new ones will be 12-13". I'm guessing that a 1.5" driver would be about right. Is that correct? So far I have not had any luck a the thrift stores so may have to buy some new drivers. What would be a good inexpensive speaker?
Love to see all the creative designs on this thread!

Prezden,
I saw some of your nice amps in the class D forum. Looks like you like to use the TPA3122 chip and 8 watts power is what you have. I don't know how good this one is but it looks like the ideal driver at 1.8 in and is rated at 8 watts from Visaton.

The frame mount may be a problem. Otherwise you will have to go up to 2 inches and use something like Visaton FRS5.

Thanks xrk- I'm not sure what amp I will be using with them. I also have a couple modified Sure 2024 amps and a Gain Clone 1875 in the works. Do you think a 2" drive would be ok for a 12" Cornu- not too big? I suppose I could make them a bit larger- maybe 14".

cheers!

Default 1" Tangband Speakers

Rebuilt my earlier attempt at using commercial floor tiles for speaker enclosures. This one has the 1" Tangband full range drivers. I used 1/32" fiber gasket material from the auto parts store for the baffles in the 4-horn true spiral layout. Legs are cut from a 3" length of 6" heavy duty plastic water pipe. Still looks nicer than it sounds. May make one more attempt before moving onto another project (which will probably be a 20" circular 6-horn design for 3" NS speakers).

Ya, you hafta think a 1" driver would benefit the most from wall loading. Is it the bass that's lacking?

What am I saying? It's a 1" driver. That's smaller than some tweeters I know.

Lot's of fun in the 'other' thread. The latest from me is more than I'd hoped.
