I have measured hundreds, yes I mean that, of those old mylars and almost every one is high ESR.
I am going to pull xover tomorrow, once out I may some more advice. I real don't want to replace all caps unless absolutely necessary.

In my experience if the drivers and diaphragms are in good shape the culprit is a crossover that needs recapping. While I have never worked on CF-4's I have worked on a number of Chorus I's and II's. Some were really sour sounding until recapped and then they sounded great. Here is a thread that may help.
Drivers are in good shape, guess I may have to look into xovers after all. Thanks Dave, I think😁🤔

Polyfill won't do anything to lessen the shrill sound you're experiencing.
How are they set up in your room? Do you have hard floors or carpet? How close are they to side walls? Do you have them toed in or pointing straight ahead?
Was reading thur epic thread and read where wvu80 had harshness in upper frequency and did poly fill and dampen horn with silicon and shrillness disappeared. I realize his speakers where cf4's and my are cf2's but it's cheap and easy to do so thought I'd try it.
Figured since I am going remove the horn it won't be that much more work to put in a brace. Also plan on running a bead of pl premium on inside edges just to make sure cabinet is sealed.
Room is not conditioned but I am presently building diffusers and sound panels. Cf2's are in front of my chorus II's that are angled out 45 degrees and tucked hard into corners. After mods the chorus II's sound amazing. I realize the CF'2s are not placed perfectly but they sound good except for shrillness, clean, clear decent bass but that shrillness I was listening to some classic rock on fm and they sounded so bad I thought speakers where bad. Switch station to a different type of music and they sounded much better.
I am not ready to give up my chorus II speakers but I think the cf2's have potential, would love to hear some cf4's. Bought these because I heard so much good about epic, cf line never planned on keeping them, curious.
Are there other mods I could do to improve overall sound without rebuilding xovers or replacing drivers? Thanks!

If you're going to sell them, don't do anything to them that cant be easily undone. What amp or receiver are you using?
Using a martanz 5004 preouts first tried Carver m t 01 and now running off a Wharfedale pro mp 1200.
Only want to do cheap easy upgrades, in others experience is it worth bracing the cabinet? Really have no issues with bass.

Been listening to my cf2" s for a week or so and find too them to shrill for my liking. Going to rope clauk and poly fill the cabinets. ( what is the best way to keep poly fill in place, spray glue? )
Are there any other cheap upgrades I can do to help? Don't want to spend much as I do planning on selling soon, just bought as I was curiousity. Thanks!

There are a few stations around here that charge more for using a CC, but they're always marked well. It's usually less than $.10.....We are $2.70 currently.

Looked at stations today, yeap .10 to .20 increase. Most stations here post one price and don't even said it's cash price. A few do show both cash and cc/debit price but not many.

Just curious as to whether or not this is a nationwide thing. With gas prices raising about a dime a day (it seems) I've been watching the price signs at gas stations to see who has the cheapest prices. It seems the common ploy around here is to advertise a really low price on the electronic display. When you get to the pump you see that it's a "cash only" price. Credit card can be as much as 20 cents a gallon more and that's normally how I pay as it's faster than going inside. It started out as one or two stations doing it but the practice is spreading vaster than the Wuhan around here. I'm not a fan.
Interesting, I will check here on Atlanta.

Thank you man I appreciate it.
I am going to experiment with fixing my speakers, mine are old and finish is not perfect anyway. I will post my results good or bad.
Strange thing is even at close examination I can't tell what the exact problem is.

I contacted the dealer I bought my rf-7 iii’s from. We will see how it goes, just a hassle...
Yea but should be worth it once done and you still have some nice speakers to listen to. Good luck with the dealer!

Yeah it’s pretty unfortunate. I’m sure I’ll have to learn to live with it I guess...
My are used so I didn't expect them to be perfect. You should on the other hand should have some recourse with the speakers being new. My speakers are cherry veneered also I wonder if this is a common problem with just cherry or other veneers also?

The pictures don’t do it justice, in person it’s very noticeable. I don’t care so much about the backs, but the distinct lines on the sides and tops of the cabinets bothers me.
I just bought some cf2's that have the same problem, edges are loose also. Not sure how to fix without put on new veneer, going to try and iron it with a towel Sunday. Don't expect much but I guess its worth a try.

You’re gonna love ‘em. They sound great.
I’d probably pay $250 for the tweeter drivers alone if I were desperate. You did well here IMO.
Listen to them a little today, not perfectly set up just set in front of my chorus II. Tomorrow I hope to dampen the horn and. check for any cabinet leaks possible change/add poly fill. Will add my lil Mike's sub's to the mix tomorrow. Think I need to start a new thread.

I used Roxul Safe & Sound for the insulation, 4" thick for the walls and 2" thick for the ceiling. 1x4" pine frames. Acoustic fabric from Guilford of Maine. The wall panels are 2'x4'. The ceiling "clouds" are 4'x8'.
Ok thanks, I am going to do a little more research but I think I can make HD roxul work. I have a different idea for frames pine/lumber is getting expensive.
Might be interesting to see the link you used to build your diffusers. I don't think most people realize what's involved.

Perfect, It now makes sense. I want to make sure I can get all the hardware first before I pull the trigger on everything. Home Depot has Birch Ply with my name on it
If you haven't bought your BB plywood I would look for another sourse. HD BB plywood or there MDF is not very good quality. I recently bought BB from rockler wood supply for a good price, they are a national chain.
Do a search for BB plywood for sale in your area. Read up on MDF there are different grades, if HD MDF gets near water it absorbs it like a sponge. Then it gets black mold spots, not good. If you do use HD MDF seal it to help keep water out.

Looks great. Would like to hear your system!
Sorry to get off topic but what did you use for acoustic material in your sound panels. What size are they, I am looking at roxul from HD - 12 pieces 3,"by 151/4" by 47". Is 3" thick enough?

Sorry I was talking about pl premium on the inside edge's of cabinet not the drivers and such. With drivers I use frost king foam tape, worked good for me in past and easy to remove speakers.
Yes source may have been part of the problem ( FM radio). Still even with cd's harshness is still there just not as bad.
