Hardware store, socket wrenches, not entirely kidding here. planet 10 hi-fi offers 33mm phase plugs for Fostex FE206 and 207 drivers.

I'm using a pair of Dave's phase plugs on my "full-tweek" Radio Shack 1197's and they sure helped the sound a lot.
I liked them before and they measured (in room) plus/minus 3dB from 65Hz to 15kHz. Dan Wiggins used Praxis to measure them at the last "Puget Sound!" speaker contest. I haven't had them measured after the phase plugs were installed, so maybe the FR got worse, but they really sound so much better I don't care

BTW: They are very well made and really look spiffy, so if you run your speakers without grills it's probably worth it even if they didn't make a difference.
Best Regards,
TerryO

Default Where have all the wooden door knobs gone?

Here in Mongkok I'm in the heart of the hardware/building supply district of Hong Kong. Just searched through dozens of stores and thousands of door knobs; couldn't find one suitable solid wood knob. Didn't every kid used to have a wooden door knob to play with? What a world we've become!
OK I may have to resort to the Craftsman section of the tool shop. We want 3/8" drive regular or long reach socket?
I did get a length of 30mm solid wood dowel.

Thanks all and Cheers
Brian

Honestly, the first thing that came to my mind was a 30mm canon round, like this one.

Stick a metal screw in the bottom of your dowel, carve to taste, drop in voice coil.

Default 1812

Thanx. A little spark during the 1812 overture could get the neighbors riled and start a war.
Did the ball on dowel last night and definitely improved things.
