He's referring to my tag line - "I can quite DIY audio anytime..."

Default Cardboard Martello

Well, I've decided to put my little fountek drivers to use thanks to this great thread. I live in an apartment and have no woodworking skills whatsoever, even making open baffles is a big hassle. Working with cardboard, however, shouldn't be a problem. The 'build' is stalled for the moment because I can't seem to locate my glue gun, but I will post pictures as things progress.

A couple of questions:

Is felt lining sufficient or does this speaker also require stuffing?

I'm considering adding the Aurasound 3/4" Titanium Dome Tweeter.
Think it's worth it? I have some 2.2uf caps and .15mh inductors,
which I could probably wire up as a first order crossover. If anyone
has thoughts on whether or not that would work, I would appreciate
it.

I don't think this is going to work if you build it with cardboard, but heck, it's DIY and who am I to say what you can and can't do !

I wouldn't worry about using a tweeter at this point, I never found the high end lacking (although I can't hear past 13kHz myself).

I believe Felt lining is sufficient without stuffing.

Thanks for the reply. We'll see how the carboard works out. If nothing else it will pass the time.

I'm looking forward to some photos - you may start a new craze here, just imagine how little it could cost, in principle, to have cardboard flat packs !

Default Flat Pack

This will be interesting to see, there was a company a couple of years ago that did a set of cardboard speakers for computer enthusiasts that folded up so they could be carried. Though i believe they were based on a planar design.

You could double up on cardboard in places leaving an air gap in between to improve the properties, even better you could corrugate thin card board in the gap to break up the sound. Or if you have some cotton wool insulate the gap with that.

I can't wait to see hows these turn out.

You never know iKea will be selling them next

Default mules

Greetings!

There is nothing wrong with using cardboard for starting purposes. Open baffle mules have been made out of cardboard for years.

I'm not sure I would recommend it for permanent install, but for just layout, experimentation, and such it works great.
