Old Coral kit speakers

[Brisso57]

The vertical brace will improve your box significantly, as well as some dynamat type of sound deadener for car to put on the Coral's stamped steel frame

Thanks. Good idea about damping the frame. I'll also glue a small circle of carpet underlay to the rear of the magnet.

[Brisso57]

Check the surrounds on the mids as they seem to be the ones that disintegrate first.

 

I have - ahem - a stock of drivers from which to select the best.

The only one I have that I can identify visually as damaged appears to have been taste-tested by ... silverfish? I'm thinking I'll try gluing a small piece of (aero-)modelling tissue as a repair.

mention is made a while back on Coral full range speakers, there's basically two ranges

the Flat series: Flat 5, Flat 8 and Flat 10 inch (rare but can still be found 2ndh)

the Beta series: Beta 8 and Beta 10 (very rare $1k, $1k5+, 2ndh if you're lucky)

the Betas were an all out design similar to Lowthers, they have a cult following and are beautifully made,

in the right box or back loaded horn they sound excellent

It's more complicated than that. There are other well-regarded Coral FR drivers, e.g. the 4A-70 and so on.

Then there are the Coral coaxials, in 6", 8" 10" and I think 12" sizes. Add to the mix the drivers sold under the "Peak" name.

Tony have you had a play with yours recently ?

 

Hi Grumps

 

No, I haven't blown the cobwebs out of them for a while.  I probably should unscrew a bass diver and check the condition of the surrounds.  The sounded very good last time I listened to them, but IIRC didn't have the immediacy I like in speakers like the Yamahas and Wharfedales.  Then again, few speakers do, even including Gales, which however excel in other areas.

The Corals are stored side by side with a huge ( about 175 litre internal volume) old pair of bass reflex speakers in which the only drive units are 10" "Peak" coaxials, which are of course rebadged Corals.  On the right material, they can sound quite impressive, but I always preferred the very similar Pioneer PAX25b drivers. When I get time I'd like to substitute the Pioneers into the same cabinets as a comparison - I have a pair somewhere, I think.    

[Grumpy]

The surrounds on the woofers are a material type of thing which doesn't seem to disintegrate like the papery surrounds on the Mids

[Brisso57]

I have a pair of Peak 10" coaxials and also a pair of Peak 8" coaxials.

Of the two, my preference is the 8" alone on OB. I did build one sealed cab for the 10CX50, but the sound was disappointing, so I shelved the project.

D'oh! Forgot to mention the Sony & Sanyo "Holey Basket" 4" full-rangers.

I have a pair of the lighter colour Sony's playing in Zigmahornets. Nice.

Interestingly, a pair of the 12SA-1 kit speakers has just appeared on fleaBay, but the seller is apparently unaware that they are a kit. If there's anyone local to the seller looking for something to suit a low power valve amp, then go for it. The rated sensitivity is 95dB.

PS If anyone who is an SNA-er buys them, stay in touch please, it'll be good to swap notes as we renovate.

[Tony M]

They're a bit of a bargain IMO.  Perfect for the low cost BFYB system that was being discussed in another thread.  I'm sorely tempted to adopt them as they are local to me and look like they deserve a good home.  But, I don't use the ones I have so it seems silly to add more.  Surely someone will snap them up soon?   It certainly underlines the fact that good sound on a budget is totally achievable.  These would pair happily with a range of low budget vintage amplifiers.

I was just mentioning the top of the pile Corals, That's a great Coral archive page, very informative. I have the Beta and general  Coral brochures. Bought a pair of Beta 10's back in the late 70's, just $230 the pair new, had the five port boxes made for them at an extra $300. Sob..... sold them, before I knew better! Yep, Peak were made by Coral, the 8 inch coax's pop up from time to time, not expensive. Also of note are the early Pioneer PAX full ranges, they had a weird phase plug that looked like a light bulb.

The Pioneer PAX range had the tweeter in the middle in a co-axial arrangement - no special phase plug. 

 

 

I suspect you are thinking of some of the Lowther range, which had some very bizarre-looking phase plugs, some in the shape of a lightbulb.

I recently saw a pair of vintage National 8'' speakers at Garry Cawseys' factory that had  an intricate double diaphragm cone  arrangement with a bulb style plug.The type No. is either 8P-WI or EAS 20 PWO9.They were mounted in enclosures,so I could not indentify the  actual version used.

[Be Quiet...Listen]

I recently came into possession of the 12SA-1 kit. It's complete, with manual, in it's original box. Not sure whether to attack the project or not.

They do sound interesting...

Does the kit include TKD cabinets?

Ah, dad (skippy124) has a pair of speakers featuring those type of drivers - possibly the Technics SB-65? Edited October 9, 2014 by pete_mac

Brisso57 - not sure. I havent really gotten it all out of the box yet. If they came with them then I'd say yes.

Hi all,

 

Again dragging up an old thread!

 

I pulled apart an old bar which had these attached in the arch above the bar. They’re in great nick because they’ve been enclosed for so long. I’d generally just like to know if they’re worth much and if anyone could give any advice that would be amazing. 

 

Cheers!
