Ikea bass traps

[sergioplanet]

I was inspired by a previous post
using Ikea Kilby bookshelf. I filled my traps
with a double layer of 4" mineral rock wool.

I use these traps as a room divider to hide my gear
when not in session and turn them around during a session
with drums, or to make 3 sides around a vocalist or acoustic guitar
works really well.

Thanks
Sergio

God bless IKEA

Does leaving the board on the back of the bookcase affect the bass absorption?
Wonder if it would work differently if there were some holes in it (the back).

Looks good...and inexpensive!

[cynic one]

crafty! next set of traps i do i'm gonna go that route.

This is great! I may very well do this in the coming weeks. Expect a message if I do.

Sergio, nice work -- these look excellent... especially the portability of the design!

I also looked at the Billy bookcases when coming up with my Ikea bass trap design (DIY Ultratouch Cotton Bass Traps / Broadband Absorbers) but decided to go with the IVAR system. I think your setup could be really great to line the walls of a control room with while providing a nice aesthetically pleasing and professional look (in addition to their use as a room divider trap).

Beautiful. Great idea!

Hi
no the fabric is not from Ikea
it's some inexpensive burlap
I bought at a local craft store here
in Austin, Texas called Hobby Lobby

Thanks

Is there anything specific I should look at when buying the burlap?

Burlap is a very simple fabric...it's pretty much the same wherever you buy it.

I thought so. Thanks

Hi,

very cool design, congrats!
I'm considering doing the same thing..
Question: Shouldn't the bass trap be "open" also on the back for optimal bass absorption?

Thanks,
a.

Typically, yes. But if there's airspace behind the insulation inside the trap, then the hard backing is acting just like the wall would anyway.

Frank, thanks for your answer! I believed that having the back "open"
would help since people around here is actually making traps with holes cut
in the framing on the sides to maximize the exposure of absortive material...

Let me be clear...for most bass trap builds the back should definitely be open. It's just in *this* case that it doesn't really matter.

In this case the construction of the box leaves (or looks to leave) plenty of airspace between the insulation and the hard back. If it were stuffed front to back with insulation, leaving no airspace, then that would not be good. Alternately one could build a panel like we build ours...with airspace between the layer of insulation and the wall you mount it on.

Yo! I just came from Emeryville. The kilby was $40 bucks so I got two flarke's $19 each. I had to steal this from dude. I finished one. I had some bonded logic left over from my booth build. I do the 2nd one tomorrow. I'll do two more this weekend.

This idea was genius. Glad I peeped it!

Sorry the picture is real wack.... iPhone

I'm working on this right now, and what Sergio basically told me was that he had 2 4" layers of rockwool stacked vertically in the shelf which is 9" deep. This leaves very little room inside when you have the frame on in the front, so I'm going to carve some holes in the back. I'll post pics when I'm done.
