Wiring for 2 tweeters

[V8 adie]

Hi there
I am building some speakers and want to fit 2 tweeters. I want to keep the cabs 8 ohms to match the bass driver and crossover. The tweeters are 8 ohms each, what would be the best way to wire these? Both tweeters in series with a 16 ohm resister in parallel or both tweeters in parallel and a 4 ohm resister in series? I hope this makes sense. Thanks

The tweeters may be wired as either 4 ohm or 16 ohm as you can design the high pass (treble) section of the crossover to suit either.

You don't use resistors in the way you suggest. Perhaps you need to find out more about crossovers.

It sounds like you may be using an off-the-shelf 8 ohm crossover board.

Supply make and model of drivers and you may get suggestions about a suitable and simple crossover circuit.

Hi thanks for your reply, I was planning on using a stock 8 ohm 2 way crossover and had read somewhere you need to match the impedance of the drivers to the crossover if you can't to use a power resister of the correct resistance?

or both tweeters in parallel and a 4 ohm resister in series?

Of the two suggestions, this would be the better one for use with an 8 ohm commercial crossover.

However, the series resistor will attenuate (make quieter) the tweeters

If the tweeters are more sensitive (louder) than the bass driver, then this may be no bad thing.

Thanks again I will try is the way you suggest. If it does attenuate the tweeters a little that would be bad either as I'm using 2 tweeters for dispersion .

Yes, I would start with how you have suggested and Galu has recommended. Parallel tweeters and a series resistor.
