2 way speaker in theory. What would you mate this tweeter with ?

Mattias S · 3rd December 2003, 08:04 PM

Peerless has many fine looking ( and sounding ) tweeters but this one has caught my attention. http://www.d-s-t.com/peerless/data/801730.htm

It measures quite good and what i´ve been told by carlssonenthusiasts, it also sounds excellent for its price. Now, what would you have me consider regarding a suitable bas/mid driver for a 2 way solution using this tweeter ?

Vifas logic series seems to be a interresting choise. Or perhaps a driver from peerless would be a nice ? Please offer me some suggestions and i would´nt mind a explenation why that perticular driver would be a good choise.

Mattias:

Well, I wonder if that tweeter needs a crossover for protection. Because if it does not, I would be inclined to stick a CSX 10" in a 2 fT³, (56 L), box, get bass extension down to 32 Hz, (F3), and possibly get away with using no crossover at all, on either woofer or tweeter. The rolloffs of the woofer and tweeter seem to naturally meet at 1500 Hz.

How's that for quick, fast, and cheap?

Over here, the CSX is about $62.

PS: One modification. Because the tweeter is slightly more efficient than the CSX 10", you will probably want to stick a single capacitor in series with it, perhaps something like a 17 uF or so.

It absolutely needs a crossover for protection
- otherwise one extremely dead tweeter.

For a first order crossover I'd say 8 to 10 uF is
more sensible as a minimum than 17uF.

Its a good cheap tweeter, emphasis on cheap
then good in context.

This type of tweeter still finds favour for use
in dipole surround rears for some reason ?

IMO designing a speaker from the tweeter down is
utterly pointless - unless you must have some exotic
treble driver.

It will mate with any good cheap mid / driver ,
again emphasis on cheap then good in context.

But if you don't get the crossover right results
will not be pleasant - try and find a design that
uses it - or adapt a design that allready has a
simple tweeter crossover and pad any differences
in the impedances and sensitivities of the tweeters.
