Adding filter caps to DR250s

Hi all.
I have an older pair of DR250s that I'm refurbishing.
I don't have crossovers in my cabs, the piezzos and the drivers are all wired together.
I've seen mention of adding filter caps to the later version of these cabs in for better efficiency, and I'd loke to add them to my cabs, but can't find any details on how or what is needed.
Can anybody supply that info please?
Regards
Monck

Order a plans update.

Thanks.
I'm happy to pay for that.
But I can't find a "build update".
Do you mean the full build plans or is there an update I can buy separately?
Thanks.

Thanks Bill.
Your link states that updates are only provided to those with receipts for the original plans.
I did not build these cabinets, I bought them, so have no original plans for them.
I guess I'll drop the plan to upgrade.
Thanks for all your help.

I can provide just the pages that cover the crossover, since it does no good to anyone who doesn't have the rest of the plans. Send a request to fiztmauricebill at gmail.com
