Looking to replace the 8" woofers in some Bose 601's I have. It looks like the depth and diameter will work but it looks like it is 1/8" too large on the inside. Could someone confirm this and if so, is there a replacement woofer you would suggest?
The best choice for this replacement would actually be our Dayton Classic 8" woofer below. This woofer requires a cutout diameter of 7.2" however. Modifications may be required for the proper fit.http://www.parts-express.com/dayton-audio-dc200-8-8-classic-woofer--295-310

Do you need to filter out the low end?
Do you need to filter out the low end below 50 Hz for this speaker to keep it from distorting?And what would be the high frequency crossover point?
Yes a HPF is recommended in order to get the most output from these drivers, something closer to 80 Hz will be better depending on application. These will play as high as 3.5kHz smoothly.

What crossover to use
On the Eminence tech sheet they recommend a high pass filter at 55Hz for this driver has any one ever used this setup?I was going to use a 1st order high pass at 55Hz and a second order low pass at 3Khz for this driver.
Unless you have a lot of "basshead" music going to it, just run full range. 3khz is too high for an 8" for a hifi application, I'm running mine at 2khz. You're limited to 50W mechanically on this woofer when used as a midbass.
