Barking Bed

beamnet · 24th December 2006, 02:27 PM

I have a problem and two possible solutions lying around in the form of 2 dynaudio 24w100 drivers.

Problem: I live in a student room, 3,50m x 4,50 m and my roommates are still not annoyed enough by me tinkering with audio. So after a dac, cd player and beefy tube amp, now its time for some woof-woof.

But, as i said, i have a very little room.

Looking for a possible place to fit a subwoofer, i noticed i did not use the room under my bed very effeciently. My bed is incredibly ugly too.

Here's the idea: Build a 110 x 210 woofer, about 30-50 cm tall, put a matress on it and have a barking bed

As i have 2 woofers, no intend or use for stereo subs and lots of volume. I was thinking of maybe making a TL and closed box sub in one. Best of both worlds?

Any thoughts or help?

You may want to make it as 2 seperate enclosures so it will be easier to move.

I had the same idea and made my HideAway sub, which was published in Ax July.

I have made a second one with Peerless 10", which will be published in Ax some time in the future.

I like the hidaway sub, but i have much more volume for the enclosure. Couldn't i get a benefit out of that?

I was thinking of an l-shaped tl, with a big (vented) box to fill up the extra room in the"l"

Perhaps you'd like to take a look at the Daline concept. What you do is design a sealed enclosure for your drivers, and then add a quarter-wave line tuned anywhere between (1*Fs)>Fb>(0.707*Fs). One of these things is capable of moving a ton of air. I've built a Daline using a 5.25" high-excursion woofer, and I'd swear it was a 10" driver in there. It's also a surprisingly musical-sounding bass.
