I want to seperate a pair of Polk Momo 6 1/2in. coaxials and install them like a component in the doors and run it off the head unit (Alpine 9887) instead of severely underpowering components off the head unit or spending alot of money to get components and an amp. I have read in a review of that particular speaker that it has been done by somebody previously. The coaxial speakers do come with a seperate adjustable crossover as well. I know this is not going to sound as good as a pair of amped components but what do you guys think of this as a very affordable option??? Do you think seperating the coaxial would sound better than leaving them as a coaxial speaker??

 

it will make absolutely no improvement. in fact, when people are installing their components, they try to put the tweeter as close as possible to the mid to improve stereo imaging (usually). placing the tweeter closer to the listener's ear can make your music easier to hear with the top down, obviously, but won't sound as good as keeping them together.

not to mention that i'm not familiar with those speakers and don't know what's involved in separating them... surgery? if so, just don't.

 

Bi-amping? I'm sure it is possible, but I don't think that it is really worth it. Will info is really good. Most car tweeters are incredible efficent, so splitting the outputs from the head unit. Front outputs for tweeter and rear outputs for mid-woofers may not gain you the sound efficency and volume you are looking for.

A second set of speakers for the rear channels (lucid style panels) is the way to go in my opinion. I tried this modification first with the stock head unit and the sound was much better.

Then I added an amp and a sub to my Alpine head unit. To save money initially. I moved the blue stock speakers to cutouts I made in the rear panels. These speakers are very efficient probably around 91 to 92db.

Good luck.

 

I forgot to mention, the main reason components exist is so manufacturers can offer higher quality speakers. higher quality usually means bigger magnets, more excursion, etc.. they could make a coaxial speaker with those features, but it would be pretty big, and not fit behind many speaker grilles. So they separate the components out of necessity(initially), not necessarily to improve sound quality. Over time, component speakers became associated with higher sound quality, so that's why most people think that separating the tweeter and the mid equals higher sound quality. but this is not always so.

 

Didn't know that. Thanks for the history. I do recall really deep 6x9 co-ax's being the hot ticket many years ago.

 

I recall one Polk system where the tweeters could be mounted stand alone, or attached to the mid in a coaxial arrangement. I'm pretty sure a/d/s also offered something like this. Is that the set you're describing? Or actually disasembling a coax to remove the tweeter? If the latter it's a bad idea, because a coax mid cone is designed around having the tweeter assembly in place, and a component mid would have a dust cone, or phase plug, in that spot. If it's the system designed to be modular, then it's up to you.

 

Not much benefit separating the tweeter from the woofer a coaxial system. In most cases, it'll sound worse than before.

 

That depends on how you have the system set up.

If you go with an active crossover system, you can adjust the time alignment/gain all the way around to compensate for the tweeter being placed in a different location from the woofers.
