Bybees for just mid/highs and also Bass???

I have the bybees filters on my midranges of my speakers and they defintely work great. I am looking to put them on the tweeters and the (4) woofers but do not know if it is worth the money to spend on the bass region?

Do they make a considerable difference on the + terminal of the bass drivers???

I have had excellent results w/bybees at the positive terminals of all drivers. I would spend the money for the bass driver. The effects on the bass driver would be the same as on the others: lower noise level, more articulation and detail.
I have been thinking of installing the Bybee oem filters in my N801's. I am not sure how this may be done. Perhaps I will only be able to install them at the crossover. Any tips for me?
I bought the Rosinante Dulcinea monitors, which have built-in Bybee Technology filters by Ric Cummins in all tweeters and woofers. And I agree with Rlxl that lower noise level, more articulation, detail and musical. PS: I also use the Bybee Signature PC, which is the best I have ever owned.
The best results would come from installing a purifier at the positive terminal of each driver. This is fairly easy to do: unscrew the front mounting screws that attach the driver to the speaker box and carefully lift them out and then unsolder the positive lead and place the bybee at the positive and resolder. Be careful to cover the speaker cone in the area near the terminal where you will be soldering with a sheet of paper or something similar to prevent possible splatter from hot solder as you solder from landing on the speaker cone.

Good luck!!

BTW: Installing the bybees has been the most effective tweak that I have done---and I'm a habitual tweaker. I have installed them in all of my electronics, pwr supplies, digital out of dac, and audio out terminals, but the most effective placement has been at the positive terminal of each driver.
I am definitely going to try this tweak. I think I have someone in my area that can help me out. Thanks.

It sounds easy enough, but what about with my KEF Q5s that have the tweeter and mid mounted together concentrically? I guess I would have to take it out to see if there is a single + lead or not.

Also, I'm not entirely clear on your instruction to solder the Bybee. Presumably, one end of the Bybee is soldered to the + lead and the other end to the + terminal on the driver??? Sorry about the dumb questions, but just want to be certain I understand.
