Horrible crossover attempt.

[Netlist]

Got this in today, hooked it up and understood immediately why it came in.
Bass speakers are slightly playing, tweeters are much too pronounced
Attached a drawing of the reconstruction of what I found. Second tweeter isn’t connected.
Any ideas how to make this “thing” sound more or less correct?

You have a 15mfd in series with the woofer, cutting out all the bass. If anything is supposed to be in series with the woofer, it would be a coil.

Other than that, we don't know what it's supposed to be so it's hard to tell. Light bulbs in series with the tweeter are long out of fashion.

Looks like the coil is there and attached to the board. Check under the board and see if the lead from the W input + goes directly to the coil.

The whizzered woofers (wideband) are probably crossed up high to the twin tweeter, like 4 or 5K Hz, possibly higher.

The light bulb is pretty bizarre. I'd scrap that and used fixed resistors. They probably used two tweeters to match impedence with the woofers, unless they were of unusually low sensitivity.
If all the drivers are 8 ohm, the parallel units, low and high, each form a 4 ohm circuit.
Just one tweeter is 8 ohm, like the drawing, but why mount both then not use it?
One blown?

Why not use some jumpers and bypass the xover boards on the woofers and see what they sound like without anything in the circuit. This will not hurt them so long as excursion is kept down. BTW, you won't develop any bass without sealing them back into the box.

The tweeters will need at least one of the caps in series for protection, and probably the resistor to pad them down.

The crossover isn't the only problem. Depending on how you stand the box either the tweeters or the midbasses are going to be horizontally placed, and that's going to cause comb filtering on the horizontal plane big time. All elements should be placed vertically to prevent this problem.

[Tim Moorman]

Agree. Too many problems, too little time, eh?

Stood on end with one tweeter working, they might be OK. Not so sure with both whizzers going what the outcome might be, but you could de-whizzer one woofer if the comb effects are noticeable.

Looks like a home-built PA cab or something.

Had another look and the cabs look pretty nice actually. The drivers look like Pioneer or the equivalent. Twin Bullet tweets are
more for looks/sales than fidelity.

Thanks guys, I'll have a more in-dept look at your comments tomorrow. Been out, too much wine for now.

The tweeters seem to be Beyma CP16:s. IIRC they have a sensitivity of 105 dB but you could look it up on the Beyma site.
