removing tweeter

[origami]

i just got a pre-fender swr henry 8x8. haven't giged with it yet, but so far it rocks. a bit heavy, but a nice alternative to an 8x10.

the hank has a totally unexpected sound. the cab is actually very vintage sounding and not modern, you would think it'd be hi-fi considering its 8" speakers and made by SWR.

the only thing i hate is the tweeter. it is hate at first hiss. i don't like tweeters anyway, so question about removing (not replacing) the tweeter/crossover:

when i turn the tweeter down, the tweeter is technically off, but still all the frequencies above 5k are not going to the 8" speakers, correct?

if so. is there a way to easily and totally remove the tweeter and the crossover so that all frequences go to the 8" spaekers? i don't know what the 8" can handle (maybe 7k tops?), but it'd be way better than just nothing above 5k or a hissy tweeter.

You can take the inputs and wire them directly to the woofers, bypassing the tweeter. This will send all frequencies to the woofers and take the crossover and tweeter out of the chain.

It should be a very easy modification.

Like most bass cabs, all that the "crossover" consists of is really a high-pass filter. The woofers get the full signal, but the tweeter only gets those frequencies that the high-pass filter does not attenuate.

You will find the high pass filter is just connected in parallel to the woofers at the input. Remove those two wires, and your tweeter is disconnected.

Don't run long-term with the tweeter attenuator all the way off. It is now dissipating the power that the tweeter would otherwise be using and can fail. It's not common, but it's happened.

I agree in most cases, but the SWR manual goes out of its way to say the crossover in the Henry the 8x8 actually splits the signal and sends the >5kHz to the tweeter and the <5kHz to the woofers. It would be interesting to know what actually does happen inside that cabinet.

+1. (I made this mistake)

My Goliath II(s) attenuator literally burst into flames, after setting it fully off for about 8 years.

Neat - good to know!
