Default 8" Radio Shack Driver

I have a pair of new Radio Shack drivers catalog #40-1043. Rated at 25 W, 50W peak, 50-18,000hz, 8 oz. magnet, 90db sensitivity, 8ohm impedance. They are a paper cone, foam surround with a whizzer cone.

I am looking for suggestions for enclosures for these speakers. I will probably be using a little T-amp to drive them, with my computer or I-pad as input. Any ideas or suggestions would be appreciated.

Probably the best sound you can get from this driver.

Oh, please! No!

That is a truly awful design, even for the original Lowther drivers. It's been years since I've looked at Radio Shack drivers, but I am sure that someone, probably GM, has a better design. Do some searching.

Sorry, got nothing on this driver, but if it's anything like the 40-1044, it's best suited for use under a vehicle's dash or rear seat deck.

1. It doesn't go a low as a properly designed TQWT can.
2. The huge suck-out 200-300Hz cannot be stuffed out.
3. the FR plot in the upper bass/lower mid is a roller coaster.

Bob,
You have a Voigt pipe design for a RS 1354 driver that looks quite good. Could this be scaled up for the OP's 8 inch driver based on your suggested scaling rule of thumb? Throat set as Sd and mouth area set as 4xSd?

Having no TS parameters available prevents one from simulating this box. But it might not be a bad start? Is the main difference between your Voigt pipe design and one suggested above is the terminus area?

FWIW, I have measured specs of many RS 8" drivers and most of them have a Qts between 1.15-2.45..........
