Default 2-way speaker question

Can you disable the tweeter in a 2-way speaker and use it as more of a mid range speaker?

Cut some wires? (easier on some speakers)

They are Polk db675 - 6-3/4" I like the sound, I just don't need another set of tweets in the sails.

I want to try it and see how it sounds, I just dont know if it will even work.

If they get screwed up..oh well, no biggie.

Depends on the crossover. If it's a component set, only running one speaker might screw up the crossover for the other. If it's a coaxial, it won't have a "real" crossover anyway and it'll be fine.

I was hoping you would chime in! Thanks.

It is a coaxial, not a component. So I will be OK? Just cut the wires to the tweeter?

of course it's ok - many do that when treating coaxials as components in Camaro front doors (powering the tweeter and "woofer" separately) -- though the tweeter is still in use in their cases, it is essentially the same thing you are doing.

Yep, you're fine. But keep in mind that when you use a different tweeter, you might make things sound too bright or too laid-back or something because each speaker system needs its own crossover to sound optimal.

But coaxials don't have anything near that anyway, so you may be good enough.

If you want to just try it, feel free and just let us know if you have any other questions/issues. Or, if you want, give us a more detailed description of what you're trying to do and we MIGHT be able to help more beforehand.

If you're putting them in the sail panels and using the original Monsoon amp and wiring then you really don't have to modify them - there's no treble going to those wires anyway.

Good point....depending on the speakers, also remember that the sails receive more power than the other speaker locations - probably between 55-75wRMS (EDIT: though your speakers would reduce this being 4 ohm impedace most likely), so be sure your speakers can handle it if this is in fact where they are going. If they can't, just pull the hatch speaker wires forward.

No, Monsoon most likely has a different crossover point than any pair of aftermarket speakers you get, so don't count on that.

Well. You sure as hell can. If you use the speaker in the back sails, it more then likely won't blow due to having a higher impedence. 4ohm vs 2ohm stock. The frequency cut-off I don't know. But it more then likely will be below the cut-off of the tweeter. Combine that with the small cap used on the tweeter (Which IS A REAL CROSSOVER!! search the web for 1st order) and the output of the tweeter would be almost none.

So, just pop it in and see what it sounds like. You'll be fine and you won't have to cut any wires.

OK, Thanks for all the replies.

I am putting(leaving) them in the sail panels. I already have a set of components up front and these particular speakers in the sails. The highs are too much so I was going to eliminate these altogether until I thought maybe I could just try to cut off the input to the tweeters.

No monsoon in the car, all speakers are driven directly from an amplifier. I also have a BA 10" sub in a Subthump box so maybe these speakers just are not needed at all.

I'm aware of what the capacitor does, I say it's not a real crossover because it's a half-*** POS crossover that only highpasses the tweeter, and it's not good enough. And first-order is almost never good enough in a two-way system.

Edit: also, to add, the crossover frequency CAN'T be low BECAUSE it's a first order crossover. Anyone who used the system would be blowing tweeters left and right, if so.

Richiec77 is correct. The stock Monsoon system has "subs" in the sail panels and the signal from the Monsoon amp is low pass filtered. I don't have the frequency cutoff but as a sub I'm sure it's around 500Hz - certainly it's less than 1000Hz. Either way it's well below the range of a tweeter. All we're concerned about here is keeping the tweeters from adding additional treble to the sound which they obviously can't with the signal they would get. If the tweeters get damaged, so what?...we don't need them in this case.

Sorry XtinctZ28, I realize it's a moot point since you're not using the Monsoon but I just wanted to clarify.
