Foster tweeter

[Godzilla]

What would you match with this Foster tweeter that's on sale at Parts Express?

Foster 025N03 Cast Aluminum Horn Tweeter 3" x 7-1/4" 279-102

I bought a pair and am stumped.

I have used them with Gauss and EV 12" back in the 1970s and 1980s.
Almost felt like buying a pair for nostalgia.

They would work well above a pair of Eminence Alpha 8" or an Alpha 10.

Klipsch people will be happy!

How about something like this and an L-pad on the tweeter?

10" Square Frame Paper Cone Woofer White 290-910

I'm trying to avoid the use of a subwoofer. The Eminence drivers above would be great but i'm concerned they won't provided enough bass in bookshelf sized speakers. I do agree the Alpha 8 and 10 were my first logical choices... i may end up with one of them but wanted to explore other drivers that might be less expensive.

Kinda pricely for the perfoemance -- even thou i did oay more for my new pair. That is evolved from a 1950s Jensen horn, it is OK but not a brilliant performer.

I'm sure they are not the best performing tweeters but they look interesting and i would like to use them for something.

How about something like this?

Jensen duette horn speakers 1956

I can use them with the 6" Dayton i have...

Dayton Audio PA165-8 6" PA Driver Speaker 295-015

Thanks for your suggestions!

I have one of those.

Foster builds a smaller tweeter with the same driver that is better -- doesn't go quite as low thou.

They look like (these could well be OEM units from Foster)

An externally hosted image should be here but it was not working when we last tested it.

3-3/8" Bullet Tweeter 270-055
3-3/8" Bullet Tweeter 270-055

The alnico versions are even better (but less efficient)

>>> I have one of those.

Cool! Dave, when you get a chance, if they are not packed away somewhere, could you give me the outside measurements? I see it uses an 8" woofer... i may have a few old 8" drivers floating around (rather than the 6" dayton i mentioned above).

Although at "bookshelf" SPL level you could get away crossing lower than 3.5K, the horn does not sound particularly good down low.
The driver you list has an upper response of 3.5K, it may have "problems" in that area.
Getting a speaker that plays well from 30-40 Hz to around 3.5K usually is pretty expensive.
I recommended the Alphas because I use a lot of them, the midrange is good sounding and they are smooth down to the low rolloff, an Alpha 6 would get you down to the 100 Hz range.
I'd be inclined to go with a known good sounding mid cone and a cheap sub below the pair.

Easy to spend someone else's money😀.
