Yes, sure is a nice old driver. Probably go for another 40 years.
I was offered a pair of old cabs today. A label on the back said Toshiba SSW120 8" 2-way. I need them like a hole in the head. However thought another pair of 8 inchers to try on an OB. Cutting the cotton type grill cloth revealed a 10" plus a Motorola horn. Forget about the plastic horn.

The working side. Looks a bit like an old CTS.

Mounted in about 25L cabs, they're a bit bass shy, also the suspension is very stiff.

These may end up on OBs. They go quite high. The horns aren't needed. That's a silk dust-cap.

Not the biggest alnico magnet in the stable, but a reasonable slug.

No date stamp. Any clues?

Heh, other than the seamless cone, it sure does!

A driver like that should have excellent low-end if driven in a critically damped or even slightly under-damped situation.

My experience with transconductance (current output) amplifiers shows this.

Westwell. I've had a few smaller with that name pass thru. In this case, i'm going to guess a Pioneer OEM.

Looks like a nice driver. Can you run an impedance curve -- that will tell us a lot.

Yeah, I'll get round to a z curve. Still re-breaking in. They have been idle for a number of years. The previous owner painted the gaskets matt black along with the baffles, and included the outer roll of the surround!!. I have treated that with mineral turps, which is helping. I'll do the entire surround with bitumen once broken in.

8 hours ago, need full bass boost, now bass control at 2 o'clock. Very promising though. Nice accurate mids, fast transients, sweet top end if directional, a bit peaky on female vocal up high, and a bit sibalent. guessing about 93 - 94 db/w compared to the modded Wharfedales.

I don't know why the unfiltered Motorola's were there, maybe he was deaf.
