And your thoughts on the 15's vs the XR model? I only had the later and enjoyed them very much, kinda regretfully sold them as they were 100% mint, very rare in this neck of the woods...

Well the 15's are a little muffled but they do respond really well to being recapped. I found that they produced a nice wide soundstage with some depth. They sound especially good with rock and arn't that bad with Jazz either. They are not my favourite pair of 70's speakers, this falls to my JR149's. The bass is a little limited but overall the speakers are very enjoyable.
I'm going to restart this thread again and hopefully do some more mods to the speakers. The whole project is just to how each mod affects the sound of the speaker. The 15's are great because they are so simple. It should be quite easy to see how changing one variable affects the sound. I've only added a small amount of additional of internal damping to the base of the speaker. I've already learned that trying to dampen these speakers too much has a very poor affect in that the output just sounds lazy and muffled. I've been reading with some interest the designs of Jeff Day's reference level Tannoy XO's and I'm hoping that lessons learned from this project will hopefully enable another step up in my already stellar performing external RFC Reference XO's on my 15" MG's. I'm already looking at several new replacement caps for the XO's and shall be trying the following

These have been shortlisted (and it's not complete) and over time will be compared to see what they offer. Should be fun!
Hi Andy
Superb thread just wondering what size are the binding posts as want to put some in my 15's?
Cheers
