Peak co-axials

Cloth Ears · 15th October 2008, 01:57 AM

I was wondering if there is a magical place where I can learn about Peak drivers. I picked up 4 of these co-axials (OK, not strictly fullrange) from the 'bay recently and there seems to be a decided lack of history on the Web about drivers or speakers from this maker. The baskets look the same as a lot of Japanese drivers from this era (I'm assuming 70's-80's).

Front:

Back:

I'll play with them anyway, but I'd like to know who Peak were and where they went...

Try searching for coral 6CX-1

I've had a single similar 8" thru here

Thanks as usual, Dave.

I'll have to try at home - work doesn't let me in to those sites...

I haven't received them yet, so I'm not sure whether they need a crossover or not. From the pictures, it looks like they only have the one pair of inputs. If this is so, then tweeter must roll-off using the induction of the woofer's voice-coil - does that sound right? Or would the tweeter crossover be internal?

Maybe it will be obvious when I look at them.

Peak 8CX-50's have actual XO's ... hidden behind the tweeter.
I suspect yours will also have something.
They look like Coral OEM's.

cheers

Thanks guys.

I had a search for them but there wasn't much that hadn't been deleted (Yahoo auctions). But, as you say, when I take the back off there might be a whole different set of numbers to look for.

Can't wait...

As mentioned they are re-branded Coral's.

The 8" version has a 2MF cap on the tweeter and that's it.

Never seen the 6", but the 8" is approx. 96dB-97dB @ 1 watt/1 meter and I'd guess the QTS to be @ .4 (or a bit less).

The paper surrounds will not take a lot of movement, so avoid high SPL's and/or boosting the lows/mids with EQ.

I like mine.

Much appreciated, Mr DeKay (or is your moniker a play on words?

)!

DeKay · 19th October 2008, 04:32 AM

You are welcome.

My moniker is based upon my first/last intitials, which has also been a nickname (pronounced DeKay for "DK) much of my life by various people.

Seemed like a good choice @ the time (latest 1900's:-) when I was registering @ few WWW forums.

I'm DeKay @AA & A'Gon as well.

Same, CE on various other sites (AK, MAC, Stereonet, Head-fi, Single Driver, ESP) just to be consistant. I'll be interested to see how they sound. I figure a couple of pairs of 'computer speakers' in sealed boxes (plus a 'subby' if necessary). would be what I'm looking for. If they're better than that, then... we'll see.
