question for those who have changed speakers in boxes

[tshorba]

I have noticed a lot of people who change there speaker in boxes use coaxial car speakers and my question is. Have you made any changes to the tweeter of the box or the coaxial speaker.
I might have missed it but there seems to be no mention of this in the posts and I was thinking why not mod the x-over to run the coaxial as
bass driver
coaxial tweeter acting as upper midrange
original box tweeter as high frequency

The specs of the drivers would need to be factored of course for optimal x-over points.

What are your thoughts?

I don't think that hard - if it fits, I stick it in

I try to go for component speakers - separate woofer and tweeter. Most come with factory crossovers already tuned for performance. However, tuning the coaxials to make them a woofer and mid is a pretty good idea.

I pull a lot of speakers from old dead radio's. I try to keep them original because i'll get more output from a BBX speaker than I would an aftermarket coaxial or component set up. I have my SHARP HK-9000 with aftermarket speakers intended for a car and it sounds pretty good but that's because it has a decent amplifier in it. But the smaller BBX's wouldn't be able to push those same speakers as hard. Here's my HK:

I think that crossing one set of tweets as midranges would be a big mistake. A tweeter is a tweeter not simply in name, but also in it's ability to reproduce the limited frequency range of a tweeter. Crossing it over as a midrange makes zero sense and will result in either a poor sounding (at best) or damaged (worse) tweeter . Most boombox speakers would normally be used as midranges when installed in home systems.

Totally agree.
If you're gonna swap, two important things to consider.
1. Speaker depth / clearance issues.
2. Ohms. close to or the same impedance driver is usually best.
You want to avoid possible amp damage by over drawing
from improperly rated drivers.
BTW this thread should be in the tech section of the site.

You should probably also consider the weight of the new drivers. New speakers (especially bass ones) tend to have bigger magnets than the older drivers. The caseings if our beloved boomers are not really designed to carry that weight.

with these Superduper words, they are the first thoughts that crossed my mind as well.
