I am running FLAC files to an M-Audio Audiophile to a Rotel amplifier (gutted and wiring replaced with CAT5) to the B20's and Piezo, with a side of an AR subwoofer. (the subwoofer was free and it honestly sounds good at low volume levels)

I have had these things playing for less than an hour and they already sound better or as good, as many speakers at a local Audiophile place. I am excited for when they brake in more. Tuesday is going to be a party night and we will see what they can do... I am going to leave them on until then.

I over-judged the box height a little or the B20's would be a bit lower. The Piezo's are on the back. This was done ON THE CHEAP. You can see the in-can filler stuff I used to seal all the speakers, well until I clean it better. The inside is Vinyl Latex caulked. The material is MDF. The wiring is CAT5 (I am so cheap using only stuff I have for free).

Right now according to them a deaf blind and dumb kid plays a mean pinball.

Oh yeah ignore the skateboard it belongs to a roommate who never uses it now... You can see the TB's on the ground, one of which a roommate blew out.

Good- you had me worried!

Hurdy Gurdy Dave (who posts on the open baffle forum) built a pair of TWQP speakers using that exact driver complement a few years ago, and put the piezo on the back too.

I believe he also cut the whizzer on the B20 down significantly.

Good cheap fun.

Wonder how something like this would compare to the Best Buys Insignia 2-way speakers ($48/pair) that recently caught the ear of folks:

Flip them upside down. If that's too low, you could tilt them back, or put short stands under them.

Better yet, cut the backs off those cabinets, you'd have Nearfield Open Baffles...

I re-arranged a little and tilted the back and now they are pretty good. The height really is not an issue now. They just get better and better sounding!

I DOUBT that the Best Buy ones could even get near these in anyway. These make the TBs on the floor sound like flapping assholes.

I am afraid to cut the whizzer cone. I also have the crossover setup for the Piezo so that it is not very loud, it does what it needs too.

I am sticking with closed I believe for now... These are computer/party speakers and I do not want them getting blown out.

I highly recommend these as a fun project or even as your main speakers if you took it really seriously. They are easily good enough to be main speakers in sub two thousand dollar systems or so.
