Default Ikea Blanda speaker, driver?

Hi,
I just stumbled over a few picture of ikea blanda speakers and got very interested in building a pair of my own. But what FR-driver a suited for the new bamboo "blanda" bowls (12cm and 20cm)?

A few drivers I looked at:

for 12 cm:
Faital pro 3fe20
Scan speak 10F?
Tangband W3?

for 20 cm:
Markaudio alpair7
Tangband W4?


I have a (sub)woofer for the bass frequencies.

These have a cheap Visaton 3.3". Please note that Blanda bowls are not perfect matches, and not quite hemispherical. You can deal with both these issues by using an insert between the bowls. This insert can help you to make a stand, furnish ports etc.

Note superb cabinet work - but you get the idea.

Cheers Steve

I was planning to use a TangBand W5-1611SA in the larger bowl. That should be about right. However my plans changed, so now I have a pair of W5-1611SAs sitting around. PM me if you're interested.

Dear Mad Max - Can't remember I worked out the dimensions with an on line port calculator. Seems to work OK. I was limited by the thickness of the spacer, and availability of pipe. A more elegant solution is to use thin ply, and build the port(s) into the spacer.

Cheers Steve

Mine were sealed. I like sealed speakers, and I like MarkAudio, although haven't tried this combination together. If you can augment the lowest frequencies with subs/woofers, then all the better.

Here's my version of the Blanda speaker. I settled to CHR-70 instead of Alpair 7 due to the price, but seeing that the enclosure works quite well, I'll probably do the next build with Alpairs.

Mayuri: Which bowls are those? They don't look like the IKEA Blanda series.

They are the IKEA Blanda Matt 28cm diameter bowl. I made a 2 cm thick spacer ring between them because the bowls aren't perfect semi-circles, they are only 13cm high.
