Here's my raw tweeter response. It drowns out the furnace. I didn't use earplugs, but I wouldn't do lots of sweeps at this level without them. The blue response is padded about 8dB, that's why the dial setting is different. I usually use -33 on my preamp dial for measuring.Attached FilesComment

Keep in mind that you can do a trial and error x-over for the tweeter since you can measure the results. That's what I do most of the time anyway, but I have lots of parts on hand. Your mid roll off is 2nd order. (Based on post #186) It may be that 2nd, or 3rd order on the tweeter will be needed. A 4th order filter might not be suitable. I can't predict anything for sure. A good sim should. Trial and error is kinda fun anyway I think.Comment

big 'ole bag of resistors arrived this morning , Thanks John ! i also see 4.5 uF caps , do you think those will be better than the 3.3 , 4.7 's that i have ?Comment

and i warned ya the 225 was 6db hotter in the graphs .... i made some pretty big padding swings but wanted to see what changes you want to try . i did put the series mid resistor before the first cap and glad i did .Originally posted by jhollander View PostComment

1/2" ply 13 x 5 x 4 .... it looks a lil weird cause its been redesigned .... take 6 outta the 225 then worry about BSC . it will put you real close to measurements .Comment
