Well thought I would just start a new thread. I have finished my crossovers for my 7B's and M10's, I decided not to use sonicaps for my upgrade as I am not sure how long I will keep these and I would rather the extra funds go to my 1C's as I know they are not going anywhere.
So I used solens instead,and for the price you can't go wrong. well upgrading the crossovers really brought these polks back to life and I am on the fence as to which ones I like better. I know before the 7Bs sounded bad and I sat there thinking the peerless tweets had to be over rated, not the case now as they sound very clean and detailed smooth and laid back.
As for the M10's they needed work when I got them so I did not get the chance to hear what they sounded like before hand as I had them gutted and saw no reason to put them back together just to see what they sounded like. they needed a new driver which Kevin hooked me up with for a great price. I am amazed at the lower end in these and in time I am sure they will even sound better, as for the SL2500 tweeters I find them a little on the bright side compaired to the peerless, so far not sure if that will change as the caps break in a little, time will tell.
I still have the grill cloth to redo, other then that they are clean, and I used dynamat and mortite on the drivers and passives
I had a lot of fun in doing the crossovers and I am looking forward to moving on to the 1C's as I want to go all out on these I figure $800 to $900 should really bring them to a brand new sound and look. thats the budget I would like to stay in anyways.
Well here are some pics and thanks to the guys that helped me out.

Good job Larry. Nice work. Fun stuff.

Really nice job there Larry!
Although, when I had put estimates together for my 1C's when I had them (for x-over upgrade and binding posts) it came out to around 450-500 using multicaps and mills resistors, b. posts from partsconnexion.Truck setup

Very nice! I'm going to be doing the same thing to my 7A's sometime soon. They've got the same XO's as yours.
I love these Peerless tweets! I think I'm gonna end up going with Sonicaps though. I'm planning on keeping these speakers for a long time, so in my case it's worth it. I'm gonna do the dynamat/mortite mods...upgraded binding posts/internal wiring, the whole works. I can't wait to see how much better they can sound.The nirvana inducer-

The resistors are MOX resistors, relabeled by Eagle, Mundorf, and a few other companies. They're not bad at all."He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you." Friedrich Nietzsche

Well if you do not decide to keep them,I hope you put them up here,I'd love to have a pair of 7's w/peerless.Could you briefly describe the difference in sound between the 7's and 10's,,preferences?JC approves....he told me so. (F-1 nut)
