Default Request: Peerless driver specs

Can't seem to find any specs or references to a Peerless driver.

Catalog number: 831864, 8", poly cone, stamped metal basket, 4 ohm

Looks like an old CSX to me...

Any help appreciated.

Just a hunch, but I think it is a CC line (not CSX line) woofer.

The CC range used 831xxx whereas the CSX line were 850xxx. The CSX line also had an inverted dustcap whereas the CC had a covex dustcap (as per your photo).

Hi Mos you might try "Wescomponents" (Sydney) site they usually have good spec's for Peerless drivers.

Hi Mos

Had a look through my old WES catalogues and nothing.

All I can find is some info in the original WinISD database for 831864.

Qts 0.26
Vas 51L
Fs 35Hz
Z 4R
SPL 93dB
Pe 200W
D 205mm

That's it.

I checked all my old Peerless literature, and nothing. Agree it is probably CC line, and I had really excellent results with those in the past.

Thanks all, but Rabz wins the cigar. I never thought of looking in WinISD's database.

Brilliant. Thanks, mate.

Don't light that cigar just yet.



Even though WinISD has the driver listed, it seems to have too few params to calc the port dimensions.

I transferred the params to LspCAD but as per usual, it says "too few parameters defined". Even using the crosscalc feature doesn't help.

Anyone know how to work out the qes/qms from the given data, which is, at the bare minimum, what WinISD needs. I just need a good working box volume and port data.

Thanks.

assuming that 93dB is at 2.8V, BB6 calculates Qms = 0.69 and Qes = 0.416

hope that helps.

Thanks, Andy.

At least that gives me an acceptable box and port size.

Default me too! need peerless driver specs

I have some 6 1/2 inch peerless drivers that look just like the 8 inchers on this post

the numbers on the back are

Cat no 031732

I have emailed Peerless and got no reply.

They are brand new and I would really like to use them.
Thanks
