Infinity RSII....??? Any one had ears on them?

As im looking at all these parts, I have to admit, I'm a little overwhelmed and intimidated by it all.
I keep finding other things to do before tearing into these. Not sure if it's subconscious or not!! -
Good sound is a journey.Don't take experimental gene therapies from known eugenicists.

As it's said...a journey starts with just the one first step.
Good luck and have fun.
I'm going out now and hooking up that ADS L810 cross-over I bought off of eBay.
I have to hot glue a core back to the board first though.Most people just listen to music and watch movies. I EXPERIENCE them. -
I've got a line on a pair of RS-IIb's......looks like the mids are planars instead of cone on the RS-II's. Pictures look good (but don't they always?) They are a couple hours away from here. Seller is asking 1500....which for the RS-IIb's looks to be full retail, however, that seems to be in the ball park for ones that have sold elsewhere. So, will see how much wiggle room there may be.
I'm intrigued by them to be sure......I plan for the future. - F1Nut -

I almost bought a pair of IIb's in very very good condition locally to me last summer. But kept telling myself I already have too many speakers. Seller was asking $1300 but think they sold for $1100.

Those planar mids are called EMIM like the EMIT tweeter. Just to help with research you might do on them. I've heard very good things about them.

a grand is about my comfort level on these....so we'll see...I plan for the future. - F1Nut

Any of you guys want my pair of Kappa 8’s let me know, I’m going to put them up for sale soon.

I'm sure someone will scoop them up. Those have servo controlled woofers don't they? -
I got one out today so I could remove the drivers and crossover. I cleaned the pots then got thier range of resistance. Then took a center line measurement for both the tweeter and mid pots. Got 2.6 and 2.4 respectively. Now I can order the last resistors I need. I'll see what available for 2.1 to 2.8 or so. No need to be exact I don't think. Right??
All the mids were great for ohms. All three ran 3.4 to 3.5.
Easy to forget how dang heavy these speakers are.

Any plans to dynamat those or is it less necessary with cast frames vs stamped ones? I just dynamatted a set of Altec Lansing computer speakers. I feel like I just crossed over some sort of line.George / NJ

They are pretty stout frams for a 5.5 inch mid. I think I'll pass. But the woofers are a thin stamped frame. I will probably do them with dynomat.

The guy who has them popped positive for Covid 19.....so, we are on hold for the time being. I'm going to be gone for the first two weeks of October so it may be a minute before we get together on them....I plan for the future. - F1Nut

If they are functioning properly, maybe run them a while to determine what setting best suits your ears and room. Then take a reading. I know as resistors go, especially on tweeters, a couple of tenths can be quite noticable. Also this way you can dial them in to match L/R.Gustard X26 Pro DAC

Thanks. When I had them playing, I had them at the 50% mark and I took that as my measurement.

Anyone have experience with Humble Homemade Hifi and crossovers?
I sat down today after getting a nice birch 1/4 plywood to map out where the parts will go. The deeper I get the more I feel I'm way out of my league.

No experience except with breadboarding simple experimental circuits. Perhaps you could look at some of these links?:

I’m sorry for being “late to the party” on this: consider pipe wrap for the magnets.They are pretty stout frams for a 5.5 inch mid. I think I'll pass. But the woofers are a thin stamped frame. I will probably do them with dynomat.

They are dipole or bipolar or octopole or something like that. Its greek to me. But they are open back and thats part of thier design as is the rear facing tweeter. I think if I put pipe wrap on the mids it would interfere.
Like I said, the mids frames are very solid and stout. When I tap on them there is no ring or resonance at all. -

I know this is an old thread that has been revived, so here goes. These are FS on another forum for information only. No affiliation. These are in Canton, Ohio.
Infinity RS-II and RS-5b $600
All are typical Infinity oak finish. All drivers work. Woofers have all been re-foamed.
RS-II cabs are presentable and still have both original grills, front and back, and the foam that goes around the back of the mid-range drivers is still in place (this is usually missing). I have not touched or even looked at the crossovers.
The RS-5b are also presentable and have the original grills and cloth. The crossovers are original and they used all film caps, so no need for a re-cap.
Prefer to sell as a set. The RS-5b are basically spare woofers and tweeters for the RS-II.
I have an additional pair of tweeters, a re-foamed woofer (clear-poly, bullet phase plug), and a woofer that needs re-foamed (a later grey-cone woofer, no phase plug) that will go with the package.

Maybe Danny Richie/GR Research would be willing to take on the crossover build project?

No, he said he would need the speakers there to fix other issues with a faulty crossover design.
-
Oh, that's too bad. I would have thought he'd be willing to construct them to the original specifications, even if there were "flaws" from the factory.

Maybe ill reach back out and make sure he understands what I was looking for. I felt my email was pretty clear. But maybe we have a miss communication 🤔 -
Yeah just let him know that you have all the components all ready to go as well.
-
Ok now..... I finally have EVERYTHING I need to start the build.
Got these last parts I today. Changed the plan a few times.
