Replacement horn for SWR Goliath III 4x10

[Raph]

I've been given an SWR 4x10 with some blown drivers - one of them being the horn - I tried the horn from my ampeg 4x10 in it (looks identical) and it works fine. So I'm wondering where I can get it as a spare, or if there's anything commonly available that would fit.

In another bass speaker that didn't originally have a horn I fitted an APT150 - works superbly but in the SWR there isn't space for the large rectangular horn. I could fit an APT80 in there (same driver) but I think the dispersion probably isn't as good, and the flare is a bit too small so I'd have to make up a plate for it to go on.

The best solution is if I can find the correct horn - any ideas?


PS - the flare is 110mm square, the hole the driver fits through is a 95mm circle.

I don't know which exact cab (are we talking original SWR or newer model?) you are talking about but it sounds like you may need the Foster 25H273.

Hey thanks for the reply! 25H273 - yes that's the one. The cab looks fairly old, it's a Goliath III and the horn looks the same as the one I had in a Goliath 2x10 I bought in 2004. Also the same as I have in an Ampeg 410HE I bought in about 1992!

I found a replacement at Thomann, and a couple of suppliers in the US - but knowing what happens when customs get hold of a package from the US, I'm not keen on that option, especially as Parcelforce add another £8 charge for what they call "handling".

What I might do is get a replacement diaphragm - e.g. [url="http://speaker-repairs.co.uk/shop/diaphragm/n30.html"]http://speaker-repairs.co.uk/shop/diaphragm/n30.html[/url] - unless someone tells me it's a risky thing to get into. I've done many speaker repairs, including the odd re-cone and re-foam, all successful I hasten to add, but never done a tweeter yet. It's £15 rather than about £40+post from Thomann.

A replacement could be the way to go. If something was to break under operation, that would be your first port of call. Let us know how you get on!

Those Foster horns are great. A very nice sounding top end - not overly harsh.

Got the replacement diaphragm as mentioned above for £15, fitting it is as easy as something unimaginably easy, and hey presto, working tweeter.

Thanks for the replies!

Glad to be able to help! The diaphragm replacements aren't too hard are they?!
