Re: Monitor 7A Resurrection - Advice Needed

So I mentioned earlier that I ordered a lot of MW6502 drivers, SL2500 tweets and crossovers from a pair of 7C's. That was a misnomer on my end.
Gardenstater, you were correct in that because of the SL2500 tweeters, the parts must have actually been pulled from a pair of Monitor 7 Series 2 speakers. After comparing pictures from the listing and pictures of known components from some M7 Series 2's, I can indeed confirm that that's what I have on order. I'm still getting to know all of the different flavors of the vintage Monitor speakers here so forgive me.
The funny thing here is that I am only one pair of passive radiators away from essentially having all of the components needed to put together a pair of Monitor 7 Series 2 speakers. Heck, I've even got some old Polk badges kicking around and some grill pegs I 3D printed some years ago when I restored a pair of Monitor 5JR's for someone.
If I'm correct, the SW105 is the part number of the passive radiator that was used in the Monitor 7 Series 2 speakers, no? That is what I have concluded after a bit of research but I could be wrong.
I have been a hobbyist woodworker for some years now, so I'm not afraid to take on the challenge of building some cabinets and grill frames, provided I have accurate dimensions/models to go off of.
What I'm suggesting is there are two ways I could proceed from here:
Option 1 - If internal cabinet dimensions between M7A & M7 Series 2's are the same, I could replace the baffle of the M7A cabinets I have in the garage, and use all of the components from M7 Series 2 speakers to create what would essentially be a pair of FrankenPolks. M7 Series 2 guts in M7A cabinets.
Option 2 (and I am much preferring this option) - Acquire plans for M7 Series 2 cabinets. Build cabinets. Source passive radiators and RDO-198 tweets. Put all components together and essentially create a pair of M7 Series 2's from the ground up. Let that scratch the itch for the time being while I patiently wait for a nice pair of Peerless tweets to pop up on eBay for the right price, buy them and stick them into the M7A cabinets. Rebuild baffle for M7A's. This way the M7A's stay original, minus the new baffle, and more true to what they were originally intended to be. This option of course would net me two different flavors of M7's in the end.
So, I guess with all that being said, does anyone know of a reliable resource for cabinet plans? I would need to fabricate the Series 2 grill frames as well. Apologies if I may have glossed right over dimensions/plans available at Club Polk, I will look around to see what I can find right after posting this.
Thanks everyone!
Fully modded 7C's with 198's are the best Polk monitors I've heard to date. You have to keep in mind that the original Peerless tweeters are aged (they are proteinaceous dome material BTW). It would be nice to see someone build both and do a full side-by-side review.

Re: What did you do to your stereo rig today?
It's certainly a different presentation than my EL34 and KT88 tube amps. I hesitate to call one tube/amp "better" than another, they're all just different and have their own character and performance attributes.
The 300b has more midrange "bloom" and greater realism with vocals and instruments, in my limited experience. The mids are expansive and deep, with plenty of motion. Just about perfect tonality too. Really nice stuff.

Re: Appliance Motor Repair?
I have a Stihl 026 I got in the very early 90’s and I’ve worked the living shite out of it. It’s a great saw. The cylinders and compression are still good after more than 30 years of hard work. I just used it today.
You know, I was wrong on mine, I went and checked and it is an 026 model as well, not 027.
It was/is a great saw. I had to change the clutch on mine and it needed a new bar because the old one got warped, by me, from using a dull chain and letting things overheat...that's about it.

Re: What did you do to your stereo rig today?
I dipped my foot into the world of SET amplifiers. I've been enjoying 8 glorious watts of 300b power. No problem at all driving my 87db sensitivity Usher bookshelf speakers.
It's a one of five of these particular 300b amplifiers designed and built by Sean Casper.
"NOS Tango XE-20 OPTs, Takman, Kiwame, and Carbon Comps resistors, Miflex copper PIO coupling caps. TJ FullMusic 300b, NOS 5Z3 rectifier, Siemens C3M drivers"
Really digging it so far!

Re: Just signed up for the SVS event at World Wide Stereo
SO I went to the even and the new Ultra Speakers are impressive. beautiful in design, very wide sound stage and super clean smooth from top to bottom.
I'd like to give them a run.
