replacement speaker cone for RCF 905

[sweetie]

One of my RCF 905s stopped working a couple of weeks ago and as I had no warranty I gave it to an RCF dealer here in Ireland who
gave me a great deal on my HD12s in late 2012. He rang me on wednesday to say it was fixed, he had put a new speaker cone in as
the other was destroyed. I don't know how this happened as I'm careful with my levels and keep an eye on the limit lights and bring
two subs for the larger gigs instead of just the single one. Anyway I collected it yesterday and he tells me he put a different cone in
and not an RCF one as he it was in stock and more powerful and he also was saving me money. The part and labour inc vat came to
€380 (£330). Here's the part (http://www.bluearan.co.uk/index.php?id=BAC15PZB100). So my questions are i) is this technically ok to do this ii) would the proper cone be more expensive and
iii) will it still sound ok with my other 905 sub?
Appreciate any comments as usual!

I may not know the ins and outs but the replacement cone is a 700 watt but the original is a 2000watt or 1000rms cone.
Does this make it less powerful. Maybe someone will come along in a bit and say different

I think the RCF specs refer to the digital amp so if its anything like with passive systems the amp is more powerful than the speaker?

It's a bit late now that they have done the work, but I think they should have asked if you wanted an alternative speaker fitted.

The rcf cabs may well have a speaker designed specifically for that box, and amplifier combination. You now have two odd speakers.

While this may not make much difference if you are running cheap speakers, you have paid a lot of money for good quality branded speakers. Which in my opinion should be loaded with the correct drivers, otherwise you are just paying for the badge on the front of them.

Don't get me wrong, B and C make fantastic drivers for a lot of the top companies, but I think you rcf repair man should have put a genuine rcf replacement in for you.
