View Full Version : Would this work?

Hey guys,
I think I may have blown one of my midbass for my speakers today (6.5 Alpine type-E components). It makes a popping sound when anything under 120hz is played through it.

I had been looking to upgrade anyway. I was looking at the Selenium 6W4P's and they look quite nice. I was wondering if it was possible to buy the Selenium's or something similar, and buy a separate 2-way cross over and hook it up together with the Alpine tweeters. I cant use the Alpine crossover as it is some funky inline thing. I know the Selenium's are 8ohms but I am not sure what the Alpine tweeters are. I have around 150 rms to work with, but I am worried the amp would send 75 watts to the mid bass and 75 to the tweeter.

Would using a kind of mix and match front stage work? If so can some one link me to a decent crossover? Does this make any sense?

Thanks guys!

If you are going to be mix and matching different kinds of speakers I suggest checking out the crossover building @ partsexpress.com. You can order the necessary parts and assemble a crossover that will work for you

Thanks I will check that out. Do you think what I have listed would work with the correct crossover?

Ugh I checked out how to build a crossover, and I really don't think I want to do that. Can any one suggest some pre-made crossovers that would fill my needs?

No pre made that are for different impedance values unless you buy the separate in-line crossovers from Parts Express for the respective impedance values.

Building a crossover is easy.

You can still use the alpine crossovers for the tweeters, good to keep that the same.

LOW/HIGH/BAND PASS CROSSOVERS from Parts Express ship same day and come with 45 day money back guarantee. Free Shipping Available. Order free 10,000 product catalog. (http://www.parts-express.com/wizards/searchResults.cfm?srchExt=CAT&srchCat=977&CFID=11561504&CFTOKEN=48905005)

You can get these individually. Saves building one and let's you mix and match drivers.

I really don't think I can keep the Alpine crossover, they are really pretty weird. Crutchfield says:

Crossovers: The Alpine SPS-610C features low-pass crossovers attached to each woofer's input terminal and high-pass crossovers in-line with the tweeters' speaker wires.

So the tweeter crossovers are just mounted to the woofer, simply remove the crossover and wire it in-line with the tweeter.you'll need to desolder it.

I am very sorry but I am a little confused...

Should I desolder the terminal on the woofer?

The crossover is mounted to the woofers, correct? And the tweeter wires from the woofer mounted crossovers? When did you buy them? What exact model number? Te Type-E have changed over the years.

Sorry it is not the type-E but the type-S. I am very sorry about that.

The model number is Alpine SPS-600C. I tried posting a link to sonic electronix, but it said a mod has to approve it first.

Basically there are two sets of terminals on the woofer. one for the speaker wire from the amp, and another that wires to what Alpine calls an "inline crossover". That then wires to the tweeter.

by your description it sounds like the xo for the tweeter is in the wire going to the tweeter. if that is true, then you just need to use the tweeter's wire to use its xo.

So how would I go about connecting that to the Selenium?

just connect it before the mids xo.

Look at the back of the old woofer, the wire coming from the amp should be electricly connected to the tweeters wires. post a pic if you can. if you can't pm me so I can get a pic directly.

So you are saying get another cross over, a more typical one, where it says woofer connect it to the midbass, and where it says tweeter, connect that to the alpine crossover, and then from that to the tweeter?

I will post pictures in the morning. Its 3 am here in central Florida haha.

by the way, making this sound really good is kind of a shot in the dark. Unless you know the frequency response/spl of the tweeter, and the xo point. You don't happen to live by me do you? I can measure this.

Notice how many people that mix and match component sets are using active crossovers? They can tune until it sounds right, plus the drivers impedence doesn't affect the crossover.

Yeah going active may be the way to go. How is this accomplished? From what i understand it involves amping the tweeters and midbass separately?

Yes, and the xo goes before the amps. it is a whole new animal. I will do this someday, when I have the money.

(fwiw getting a active hu (radio) seems to be the best way to do this.

Yeah after all this it might be best just to go with a whole new component set.
