Old Radio Shack Speakers

Nova 6 Front. It isn't totally clear does the woof have an inverted half-roll surround?

Sealed box?

Nova 6 drivers, got a side shot of the bass driver? What is written on the back? From the basket it looks like a Coral OEM -- looks nice. Note that the tweeter is open back -- that is a good thing.

Room for some mods that will make them sound even better.

And the other one ... no pics of the back? Bass reflex and a regular half-roll surround (ie the surround sticks out)?

Yes, it is inverted, I am pretty sure it is foam.

The box is sealed

Can try to get pic of the side tomorrow.
The writing on the back is above in the thread.

The foam surround sticks out. The back is plain. I will try to get pic of that up too.

I couldnt get a good pic of the back plate. It says Cat No. 40-4019A. It has a switch for HF compensation. And says manufactured in Japan for radioshack a division of Tandy.

What does LoEff mean? Low Efficiency?

That would be my guess.

I should have at least one driver with that basket down in the lab. I'll get a picture later. Those drivers also came with alnico magnets -- they are REALLY choice.

I wonder what ever happened to Coral?

Not too bad speakers,as you got them free.Normally you get them for about £5-£10 in a car boot sale,that sort of thing.
But hopefully they work well,and don't distort.
As you don't know how good or badly the have been treated,they are are probably best for background music.
Although 15w rms for an 8 inch woofer is weak,and 45hz-3khz for a 8 inch driver is a poor frequency range,when normally 8 inches go up to 8 khz.
Also check to make sure that the foam surround hasn't perished,you can do this pinching the foam with your fingers[gently],and if you feel stickyness,thiness,or it crumbles;you know you've got some damage.
For a cheap make[Radioshack] the magnet size is pretty large.
Hopefully you can unsrew the speakers from the ported box,and see if they are even better.
