Do you buy tweeters and swap out tweeters regularly? Do you want a way to be able to easily mount tweeters on-axis and make them look nice? Do you want to mount tweeters up on your A-pillars to avoid as many diffracting surfaces as possible?

If you answered yes to any one of these questions, I have just the solution for you!! My friend Glenn (GLN305), has come up with a very inexpensive solution for tweeter mounting that allows for easy swapping out of tweeters, makes it easy to mount tweeters on-axis, provides a certain degree of adjustability, and makes the mounting look nice. Glenn was kind enough to install a pair of Scanspeak Illuminator 2004-6020 tweeters in the A-pillars of my Mazdaspeed 3 and so I took pictures so that I could share his very innovative design with others on the forum.

Parts: (1) 2 x PVC end caps (find ones that fit your tweeters, the ones in the picture are 1.5" diameter; some tweeters may need bigger end caps), (2) threaded pipes (in Home Depot these are called steel nipples. Yes, the jokes about nuts and nipples are endless) these are threaded and used in lamps to thread the power cord through), (3) hex nuts, a (4) a can of bed liner to create texture, and (5) optionally, a can of spray paint in a color that matches your car.

Next, sand down any imperfections on the end caps. Then drill a hole at the desired mounting angle where the base and the sides of the end cap meet. These have an approximate 45 degree angle for on-axis mounting.

Spray the end caps with two coats of bedliner. In this picture, Glenn stuck screwdrivers into the holes and then put a wire tie on either side to prevent the end cap from sliding off the end cap so that he could spray paint the end caps and then leave them out to dry. The bedliner provides texture to the end cap. After the bedliner, optionally, spray the caps with a color suited for your car. For example, you can use a can of touch-up paint to match the paint to your car's exterior paint.

Thread a threaded pipe into the drilled holes. They look like little ack ack guns. They appear grey in this picture due to the flash but they are in fact black, as you can see in other pictures. Use a grinder or pipe cutter to cut the length of the threaded pipes to slightly more than the thickness of your A-pillars.

Remove the A-pillars in your car, drill a hole in the A-pillars, and then fasten the tweeter pods to the A-pillars by pushing the threaded pipe through the A-pillar and tightening a hex nut on to the threaded pipe. Thread your speaker cable through the threaded pipe and connect to your tweeter. The picture shows that Glenn soldered and put heat shrink around it but you can also use quick connectors.

This is a really simple and elegant design, I like it a lot. I wish I would have seen this before my tweeter pod debacle.

Yeah, looks like a good result/effort ratio. Any finalized pics?

Slide the tweeter into the end cap. If the tweeter fits loosely into the end cap, determine what the difference is and wrap some material around the tweeter so that the tweeter fits snugly into the end cap. For example, use some electrical tape around the side of the tweeter (near the top) if there is a very small gap, use velcro if there is a slightly bigger gap, and use weather stripping if the gap is fairly big.

The mounted tweeter looks like this:

Note that the tweeters can be swiveled if you don't over-tighten the hex nuts.

Total cost was under $20 for both. Total time spent was less than 3 hours. We did it over 2 evenings because it was humid here in Austin and we had to wait for the bed liner to dry.

those look really familiar...

The real question is how do the scans sound?

 

[boogeyman]

looks great very creative

 

[SSCustoms]

That's thinking outside the box! Well done!!!

After looking at about a hundred nearly impossible (for my minimal [read--non-existent] skill level) insyalls on a=pillars, this looks AMAZING. Will be using this in the coming months. Now if it was only this easy for woofers in a 2007 VW GTI...

My tweets may not go in the kicks after all...........................

It is a brilliant idea. Simple, functional, and looks good. James (SublimeZ) had his tweeters mounted in the same way and the improvement was dramatic.

 

[rockinridgeline]

Not bad. Great way to get them mounted without spending a fortune. Necessity is the mother of invention...

 

[volker]

Awesome idea, thanks for sharing !

Very nice, I will have to try this sometime. My Blaupunk VC100s are too large to flush in the A pillar so this would work nicely. Thanks.

One of the benefits is that they look nice and provide functionality. Also, you can swap in different size tweeters very easily. For example, I decided against the Morel Piccolos because I was concerned about mounting. With this method, it is very easy to mount even large format tweeters like the Hiquphones very easily.

 

[Maddman]

nice write-up and simple! well done.

 

[shadowfactory]

I thought large format tweets were not doable in my car without some fancy glassin, but this is much better/cheaper/easier/awesomer! I am totally doing this when I upgrade my tweets many millennia from now.

gonna go to menards with my speakers tomorrow and try to do something like this with a mid and tweet
