Test cab and crossover for my new speakers all done - time for testing, measuring and EQ.

Sloppy paint job, but nice sound! The bass on those must be crazy IRL.

How do they measure on and off axis? Using DSP for flat FR in room?
post #437 of 498
Here are the initial in room measurements @ 1m, I have not done any off axis yet.

I have been adjusting the levels on the cross over to get as flat as possible. I expect the lumps in the bottom end are due room modes and limitations in my measuring equipement.



No DSP - will correct with analouge circuits.

Yes, below 200hz is difficult to measure due to room nodes and floor bounce. Do you have any bass traps?

Other than level matching, the only other thing that would concern me is the blip of distortion at 600hz. What are your crossover points?

It must be cone breakup on the seas(edit: cone breakup is over 1K so cause is still unknown). The x-over points are 300Hz and 2kHz. There was a rattle while testing - this may have been at 600hz. I may need to tighten the screw for my next test smile.gif

The green plot is the current setting, it has a little higher gain on the mid and tweet.

No bass traps.

CD22RN4X? You'll either need a steeper slope or a notch for the breakup.
