Here is one of mine.
Pay no attention to the Vas in my post, looks like I clicked the wrong thing.
Measurements Iâve gathered for the 55-5670 over the years from a few folks seem to either follow closer to factory specs or tune higher. Makes me wonder if that is the difference between before and after breakin.
What do you mean by this?
You can over excurt them a bunch and their voice coil doesnât slam into the back plate, making that horrendous popping sound.

⌠like the rs225 when the bass line hits. ![]()
So not more ârealâ xmax, just safer. The RS has plenty of xmax. Dayton/PE should update them with a bumped back plate or a bumper for the VC to hit.
I ordered a pair of those Wavecor from Cinergy, I think I will be doing either a large MTM or a TMM using these Multicomp 8" and that tweeter. Might be able to talk Nick Claus into building a pair, as well.
Only 96 left, great job guys!
I agree on the Reference woofers lacking bump protection. I smoked a RS180 when it jumped the gap and destroyed itself against the back plate. Better soft parts or a bumped back plate would help tremendously.
My MCM 8âs arrived today, that was quick. Peeked then stashed in basement shelf. Cone has sim look to wavecor fiber paper.
Also, hereâs a snapshot of those 22mm wavecors ($15) at CinergyAudio in the augerpro elliptical waveguide intended for css ld22 - used fuzzy surface.
I would like to see some measurements of that tweeter in that guide. Looks fantastic.

Almost there!
Damn! Hittinâ hard fellows!
Received 2/3 of my order today the rest should be here tomorrow. ![]()
Down to 44 and I have 8 in my cart. Do I really need these?
I think I have to get 4 more. I was debating on 4 or 8 for an ISO setup. With one pair per tower I will have a 4 ohm load. Two pairs per side, back to 8 ohms. Still should have decent sensitivity with one pair per side.
I just ordered a dozen because with eight I donât get free shipping and 10 is a âweirdâ number. My thought process should be analyzed by a professional.
sigh
I have a pair on the shelf. I really want to buy 2 more but I think Iâll wait and pick up a pair for like $10 off the back table at InDIYana in a year or two when one of you guys realize youâre not going to use them. ![]()

This is the long play. I donât like how accurate it is.
yeah.. I probably should have just ordered 8 instead of 6.. since JR announced his plan for MTM. I have a friend who is teetering on trying a build. If I already have the drivers for him to use that might get him to follow through.
