Trouble with crossover RCF Event 6000

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have came across some old RCF Event 6000 Fullrange 3-way cabs.

They are 2x 15"+1x8"+1".

In one of thecabs the high-mid sounds more harsh then in the other cab.

I have a photo of the crossover. Is it possible some component in crossover is broken?

Previous owner said that I should change all the resistors? What you guys say? What is likely to be the problem?

The speaker dont sound terrible its just one cab is smoother sounding then the other.

I really appreciate your help

	first step in fault finding here would be to swap the high drivers from one cab to the other, to see does the problem move. if not, then the mid drivers..

	Also check the board for dry / fractured solder joints and also lead out wires for breaks. Edited by fatfreddiescat - 11 November 2018 at 2:51pm

	When further investigating this I saw one of the midrange was wired out of phase. When I now listen the sound is better can this really be it? Next problem I have is 1 of the 15" woofers are loosing inte foam surrounding att one place. Is there any cheap solution for this without recone the whole woofer yet? I also wonder which RCF model is it? On tag it says 15 530 can it really be rcf 15 lp 530? Then its still available right?

	Pic of foam surround? Shouldn't be foam, spec says polycotton.

	I would take picture later tonight. How about the out of phase wired midrange can this really affect overall sound very much?

	Out of phase midrange will make a big difference. Edited by Pinyorouk - 11 November 2018 at 6:30pm

	Am I crazy when I felt that the out of phase 8” midrange was playing ”smoother” then the correct wired 8” that sounded little bit ”harder”?

	Polycotton it is sorry not foam. Has anyone repaired something like this with any success?

	Going to need a recone, kit at Blue Aran is £101, new driver is probs best bet at £134.

	Is it even wort it to just try some fiberglass net and then some kind of rubberpaint over it just so I can test the speakers properly before buy new driver?

	Worth a go, find some fabric as similar as you can, then stick to the surround with PVA glue, leave to dry then peel back the gasket and glue to the frame with contact adhesive.
