I'm not sure man, I just thought id let you see what an unfiltered 871s looks like. The spaker was measured in a normal room with no room treatments at all. From 150-200hz on down its not going to be that accurate anyway. We did one measurement with the mic about an inch away and it measured ruler flat all the way up. Id say over most of the freqency range it was +/- .5db no peaks or anything like that(lower midrange and up).

How good will these serve as studio monitors?
I have a subwoofer.

I finally hardwired the notch in place after admitting defeat to its necessity: http://www.vikash.info/audio/W3-871S/listening.asp

Adam, I wouldn't have thought these were suitable for studio monitors.

Win some - lose some Vikash! With a bit of luck you will forget it's there after a while and just enjoy the sound!

That's what happened when I added the compensation circuit to my OB's. I didn't like adding something else in the signal path but after a week or two I forget that they were there.

I guess it's because of baffle diffraction? I experienced similar situations until change in baffle shape and driver location.

It may well be. John makes a point of the first design with more effort gone into baffle diffraction so I guess that would be a fair judgement George. I very much would like to compare with John's preferred design to how much all this diffraction malaki actuall makes. (are you reading this John? my postal address is... )

I tried living with them off-axis where IIRC the response is better unfiltered. But wasn't satisfied with that.

It looks like you are using wire wound resistors. I would recommend getting something with at least 25W~100W ratings and thicker leads. Technically this will be more compatible with driver rating. Inductor wires no less than #16 wire. I think you will hear better resolution.
