I just wanted to keep this project as simple as possible. I'm going to try the Bamboo drivers next due to their much better treble extension.

Thanks guys.

The inner walls in my apartment have no insulation in them and the elderly upstairs neighbor stays up late reading. In previous apartments I've had inconsiderate neighbors watching movies with their sub turned on keep me up late on work nights. I don't want to one of "those" guys.

I've been looking at both of those drivers too. The FE 107E looks like it's more controlled in the treble range than the FE127E. I've been debating between the 107 and the Bamboo since they're around the same price. It's a shame places don't have loaner drivers to lend out to potential customers to see if they like the sound before buying. But at only $40 each I wouldn't mind getting a pair of both for comparison.

I assume the amp that powers the little cubes is in the subwoofer unit? If so then you'd probably be better off just building new cabinets for some new drivers and then using the amp in the sub to power them.

Wow....DIY speakers have really inspired me....I'm going to do some more research and find out whats a good combo for me...

Ill probally post a thread when I wake up...but these look really nice...just clean up the edges, and throw on a coat of finish?

Where....do you find stuff like this...to learn?...is there a forum?

heatmizer · 06-20-2007, 04:04 PM

diyaudio and parts express have a decent speaker building forum

If you are thinking about using the Fostex FE107E take a look at:

That’s where I started and ended up with my version

I think it's a great little speaker. You won't rock the paint off the walls but, for a small speaker, it really does the job. Add a sub and you have a system that can rock with the best of them.

Have fun,

Pete.

All speakers pictured in this thread look awesome!

I've been meaning to post this for a while now, but a while back I built an alternate box for one of my TB drivers. I decided to use 4" PVC to make it easy and quick to make changes in volume and configurations. The volume is close to that of the wood enclosure so they have similar frequency responses but there are definitely differences in the sound presentation. I imagine this is due to a number of things such as plastic vs wood, different internal standing waves and reflections, different dispersion properties, etc.

Recently I tried something that I've been thinking about for a while now. I love the tight bass of sealed boxes but I also love the deep extension of ported designs, so I've been pondering possible ways of getting more efficient bass coupling from a sealed design. Basically I'm using a thin plastic membrane (currently saran wrap) to keep the internal volume sealed but also allowing the bass energy inside a low resistance path outside. So far it's been pretty successful, the bass from this speaker is more pronounced and a bit deeper than from the other box. If you get close to the membrane you here very deep and tight bass. Now I'm thinking about ways to improve the coupling to the room, without using a massive horn, to get that same level of deep bass at the listening position. Anyways, I just wanted to share this ongoing experiment.

From the XS to the Sonic amps and thiese, u are amazing dude..

I know I said I didn't want to add a tweeter to keep it simple, but I've been experimenting with with one for a few weeks now and there's no way I can go back. I'm using my BG Neo3-PDR planar tweeter from another project crossed in with a simple single film cap and I've been trying out various different crossover frequencies, tuning it by ear. These tweeters go up 28kHz and it's painfully obvious how limited the top end of the W4-1052 is when I disconnect them.

Since I'm pretty satisfied with this combo I'm going to build some new enclosures to make them look nicer.
