The only way to know for sure is with real measuring equipment and software. You can pick up a mic and mic preamp for under $200 and software like Arta you can grab for free.

crossover

Hi there

I'm stuck with one basic crossover question

I'm using an (http://www.parts-express.com/pdf/290-407s.pdf ) and use a first order crossover.

Coil is 9.6 mH, looks like 135 hz crossover point

So at the first 6 db down , I subtract 6 db from 95 db at the 270 hz point ((89 hz ) , 12 db from from 94 hz at the 540 hz point ( 82hz ),18 db from from 96hz at 1080hz ( 78hz ) and 24 db from 105 db at the 2160hz point on the hz scale ( 81 hz ) so the crossover curve goes horizontal at that point ,rather then down thanks to that awful hump at 2000 hz

So all the smooth crossover lines you see drawn , assume that the driver's output is absolutely flat?????????Thanks for your help
