No P&P at cost has to applied as I hope some / most can be collected. Packing safely is a pain, even more so with tweeters after mods.
Unfortunately collection is not an option for me. How much would P&P be?

I'm still not sure whether to go for Doc Mod drivers for the JPWs or just go for Cubettes. One of the things putting me off Cubettes is that I would probably need new stands to get the tweeters at a similar height as they are now unless I was to put something between them and my current stands. Approx. £200 for Doc Mod mid/bass drivers and tweeters versus £330 for Cubettes :-?

Cubettes are £350 now.

Drivers £170

£10 would cover the sending for drivers.

Sorry, I think I have confused matters, I was trying to get an idea of how the total costs compared.

I am just looking to buy the mid/bass drivers at the moment, which according to the link would be £120 + £10 P&P as you have said above, if that is correct I will send payment tonight.

Hi Doc, payment sent via PPG for a pair of the 8 inch mid bass Doc Mod drivers.

I've got a couple of pairs of soft dome tweeters that were previously in other speaker projects that I am thinking of trying, a pair of Morel DMS20 and an unbranded pair that I purchased several years ago but do sound quite good in the current speaker.

Tweeters arrived yesterday. Much appreciated that doc :clap:

Fitted . They look much better imo.

Fitted with clarity caps 4.7 uf caps measured to % tolerance and 15 ohm resistor. Far to dull . Removed the resistor so now just a cap on postive terminal. That's much better. Now undecided on some records sounds fine. Some two much especially if volume is increased , more experimenting needed.

Try dropping the cap value to 3.3uF. Crossover point is probably too low. 3.3uF willl raise it a bit.

About 10 ohm probably best. Also they are unused tweeters which are now doped so will need a couple of days run in and for the doping to loosen up.
