haha, semi recent vernacular. Its all 'wha guan blood' and 'chillaxin' round here.
Look what I read in another thread ( about OB/planars---in the multi-way forum)
The BMR drivers sounded pretty bad tbh. I wasn't expecting a great deal from them at £10 each but they sound really nasal despite the frequency plot suggesting they are good
Happens that the nasalis placed right where the frequency dip ( and impedance peak) is, even if it's a 2" driver instead of the bigger Hi-Wave that you choose.
I think that a 0,5-1 mH coil might work to let the speaker only play the bass.
Maybe you have around some old paper cone tweeters around, and you can play with caps ( capacitors) with them, also some waveguides, if you happen to have some old woofer cones, about 5-6" in diameter for a Frequency Cut at about 2 KHz ...
I would have suggested to look into the Visaton brand on RS_components, but they display only some models.

So I went for the BMR 3 inch drivers, despite the possibility of them being rubbish, as they were cheap and seemed perfect for my needs and enclosure....
I must admit when I first wired them up they sounded pretty bad sitting on the worktop, but as soon as I tried one in a bowl and sealed it in, they came alive!
Very impressed with the bass response out of these little things, and an excellent off axis response - you can walk around them, and have them pointing upright (as pictured) with very little frequency change.
The gold fish bowls were actually transparent, and I didn't want the poly-fill and wire showing, so I have sprayed the two I will be using for the final enclosures silver inside. I am now waiting on the sticky backed car sound deadening stuff and I will line them, stuff them, then glue them up.
I am thinking I will actually sit them on wide low tubes, as that way you can change the angle they point at just by moving the ball on the tube.....
Here are a few pics so far:

So they are all finished!
The tar foil sound deadening stuff worked brilliantly to make the bowls very 'dead'.
I am amazed by the SQ of these - I think helped by being placed against a wall and not far from the ceiling (firing downwards into the kitchen) so the bass is reinforced.
I had a pair of monitor audio BR2 which these have replaced and to be honest, my wife and I think they sound better!
So goodbye big MDF boxes, and hello funky, petite, black globes!

Splendid bit of lateral thinking on these enclosures. Well done.
Looking at the listings, they even do a set just for the home theatre crowd with a free centre speaker …

What specifically did you use to damp the walls?

I got it from a local garage, but basically it is a thick gooey adhesive then a 3mm layer of tar like goo, then foil (apparently designed to deaden car panels in car doors etc.). I stuck it in strips on the interior overlapping them to give a good covering.
It weighs quite a lot (presumably fairly dense stuff) so the enclosures got a lot heavier, but after doing one bowl, and knocking on the side of them both, the difference was enormous - the dampened bowl was just a dull 'thunk' like it was full of sand.

Similar to this stuff - but mine was a little thicker:
