On a flat surface, rotate it against a pencil in a height guage.

Good to see... i've been contemplating such a build ever since i saw others using the blanda bowls... the MA Alpair 7 is a good fit with 9.1 litre. Make the slot port act as a stand.

I'm doing my painful salad bowl sanding process.
Mind is a Alpair6 sealed, 3 litre. I'm building a 6" subwoofer to go with it.
We have another version with a ring installed at the parting line.

Ditto. I have a pair of the Jordans which would fit very nicely in some of those. 7-8 litres sealed is ideal for use with a sub and no need for a reflex port.

Pity the nearest Ikea is a three hour round trip. Hm. Some plotting needed ...

MarkLai, those look excellent. What is the aluminum ring and How do they sound?

Have you thought about using twin subs, push pull, isobarik like the link in the next post to cancel out the forces?

The sanding is a bit of a nightmare, i went over every square inch but its creates some much fine white dust its hard to see what your doing. Did you find that it left a dusty/cloudy residue on yours? I ended up putting some natural oil on to help to get rid of it.

Its a shame Ikea don't make the wooden blanda bowls in a 36cm version like the aluminium ones. I would love to make a isobarik sub like TNT on this forum, just my metal working skills are appalling.

I just finish my sanding today. I'll try to wax them first. If not good, I'll lacquar them.
I don't hear them yet. I've a Alpair6 base reflex, 7L, from EUVL which I like them very much.
The silver color AL ring is just an adaptor ring glued to the salad bowl. I find that it is too thin to drill screw holes onto the salad bowl, which is 8mm thickness only.
Single subwoofer is good enough for a small room which is typical in Hong Kong. Mark Fanlon knows that.. haha.

very inspiring idea!

MarkLai,
I highly recommend reconsidering waxing first. although lovely as a finish, it is a nightmare to get off perfectly, and it must be perfectly removed if you want to lacquer them, or else the lacquer will come off where there is residual wax.
