My Mona-Lisa, SDA-CRS+ Conversion for 4.1 TL mod

[audiocr381ve]

Gentlemen, I've decided to convert my Blade Blade, Dual Crossover, 1986 SDA-CRS+'s to a newer version CRS+. I purchased newer version crossovers from Vr3MxStyler2k3 (single boards) that will enable me to do this. It's the re-wiring and mounting that I will need help with understanding. I'll post tons of pics, ask a lot of questions, and be overly descriptive to help the next guy down the road.

Goal:
I want these to be the best that my budget will allow and the reason for conversion is so I can perform the 4.1 TL mod. I haven't seen anyone perform the 4.1 TL to dual board (aka crossovers), b/b (blade/blade), 1986 CRS+. Their are three versions of the CRS+'s, and this is the only one that, as far as I can tell, can't be "TL'ed". If someone has done this with success, PLEASE share.

First question, with the newer version single boards, which speakers will I need to make these a true newer version CRS+? Currently, they are all 6510's. I should probably put a WTB ad out asap.

Found DK's thread from when he did the 4.1TL Mod to his 1989 version CRS+'s.

Looks like I'll need two 6511's. Please step in if I'm missing something

I do know that the newer version CRS+'s had different PR's (passive radiators). I'll have to look into that.

Inductor upgrade may be your biggest stumbling block, unless you have this covered already.

I'm probably going to use the Erse Super Q 17mh 16awg that I used with my 2B TL's, which are a whole lot smaller than the Solen's. I don't think that's going to be a big issue. Thanks for chiming in.

Does anybody see a problem with what I'm attempting other than the guy who's doing the work?

The point of no return... lol
