thanks CZ, i used the Audyssey mic that came with my Integra.

glad to know that your CV is also rolling off around the same freq.

did you take close mic (1m) measurement on them?

well, remeasured the speakers at 3ft and FR seems a bit better. it now falls off around 14-15k. i think i can live with that. i guess i can't expect to get roll off at 19-20khz, according to specs.

I wouldn't be too concerned about the fall off on top. How about those swings from 500 to 800hz and 1500 to 2300hz roughly. Looks like this cross over could be imporved a little. Also looks like it smooths over a bit at the LP.

Can you post the XO schematic? Possibly the tweeter could use some additional padding.

Nice work BTW. I'm impressed with the Baltic Birch finishing. The chip in the wood wouldn't bother me too much. It could have been worse. Like on the front baffle near the top or something

Your impressions match the frequency response.

I looked at the picture of the XO and I don't see a resistor for the tweeter, but that is just me looking at a picture. Can you check on that?

Oh, and I'm probably going to build cabs for Baltic Birch next. Possibly Maple plywood. Would you use the Shellac again? I think they look pretty good.

i don't have the x-over schematic, it was built by the desinger.

also, the 1m graphs were focused on the tweeter so the mic was aimed directly at the horn and probably missed out on the mid bass.

i would definitely use shellac. it shows the natural feel of woods very well. easy to apply, and dry up very quickly so you don't have to wait days/weeks to install your components and have a listen.

and from what i've read, baltic is a pain to stain and doesn't take stain very well.

just make sure you get nice quality 13 ply baltic.

Ah, ok. Makes sense why the 3m is a little flatter. If you find it's a bit to trebly, add a 2 or 3 ohm resister in front of the tweeter.

Enjoy your speakers
