10" for 3 way

[dusty]

guys,

I have 4" flex unit from skaaning and I'm looking for a 10" woofer for a 3 ways design... can you guy suggest some thing... I original intention is to use eton 11" to cross at 300 .. however .. lost all the money in the subprime market (it is not a joke).... $150 would be maximum.... no aluminum cone... hivi is what I have in mind now but I afraid the flex will not do well to cut at 200 hz.... thanks!

Considering budget and no aluminum, Peerless SLS 830668.

What about the new SB 12'' driver from Madisound?

Why 12" not 10"... I know the 12" has higher spl which matchs with my mid ... but..... is it O.K to bring the 12 up to 200 or 250hz...

I don't know if anyone has explained the FR blip at about 130Hz, but otherwise it looks fine. Maybe a little larger box (didn't model it).

Consider using a pairs of 8" woofers instead of a single 10" in each loudspeaker. (for examples of good implementations, look at the Wilson Puppy, or the lower half of the Joseph Audio Pearl) The smaller woofers would be better behaved in the upper prortion of their range. And good ones will not suffer much in the lwoer end of the range. The pair would spread the range of frequencies affected by interference from the floor reflection, softening that problem. And you can use a narrower baffle.

If you really want to avoid aluminum, take a look at the 8" Peerless Exclusive 830884, $326 for four.

That said, I would suggest rethinking the aluminum if you are willing to go to pairs of 8" woofers (pushing the characteristic breakup resonances deep into the stop band). If the breakups are trapped, and well down in the stop band, the aluminum will not present any problem. You can get four RS225-8 8" 8_Ohm Dayton Reference Series woofers for $182.52 Be sure to look at the response curve of the breakup before dismissing the idea.
