Hi Tom,

Measured and calculated 40Hz
Just imagine that the first biggest problem in trial listening was to get the volume down
Had to get my old 2xEL84 15W and even convert that to triode to be able to adjust the volume within an acceptable range.
Next and initial challenge was to "calm" the bumps that a DX4 does have...and with minor filtering it sounds fantastic (still thinking about flatening the impedance curve though)

(In Dutch but enough pics over here: http://www.htforum.nl/yabbse/index.php?topic=112675.0 )

Arno

Arno,

Thanks for the measurement and the link. They're very nice looking and I'll wager nice sounding as well. I'm sure you'll be getting hours of enjoyment from them...

Hello Clk230. I'm curious, what type of beautiful striped wood are you using on the front & top of these speakers?

Looks to be plywood ends to me. Does have an interesting appeal.
