Request: Peerless driver specs

[Mos Fetish]

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.

 

[Dave Bullet]

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.

 

[Mos Fetish]

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.

 

[Mos Fetish]

Thanks, Andy.

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

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
QC 910304
Cat no 031732

I have emailed Peerless and got no reply.

Where should I look?
They are brand new and I would really like to use them.
Thanks

Sure that's not 831732 , in which case

Fs = 40
Qms = 1.7
Vas = 24L
xmax = 5.5
Sd = 130cm2
Qes =.47
Re = 6 ohms
Le = .5mH
Z = 8 ohms
Pe = 90w

I found the right number

I found the right number thanks to you!!
Its 8317320

Are the specs similar?

 

[heretohelp]
