subs for Sonus Faber Cremona M floor standing

Dear Johnnyb53: +++++ " A lot of people are finding that running the mains full range helps get a good blend in many cases. " +++++

absolutely right but all those people have that kind of set up because that was they learned through the AHEE and that's the old and IMHO wrong way to set up subs for a two channels system when you have passive speakers that crossover 100hz and up.

You posted you already know everything I posted so please think on what you are saying because seems to me that as in the Analog forum you are biased " against " not what I post but against " me ", I don't care but this can't make a good thing for you.

Johnny, maybe I'm wrong about that " biased against... " but if not : how could you explain that in the longest and dedicated Agon thread about MM/MI cartridges you almost don't posted when you are an avid fan of MM cartridges. Even that I invite you to share your value experiences about and help all the other people that need does experiences?

Anyway, this is a free forum and as always my posts are always trying to help other persons and not the: who win attitude so often in these kind of forums.

Raul, IMHO, a sub that matches well with SF Cremona M's is going to be a sub that is suitable for Erictye's room. Whatever sub that he ends up with will have to be fairly quick and easy to 'blend' with the Cremona's. In my system, the answer was the Rel T5, because a) I have a very small room and anything larger will overload it and 2) my mains (SF GH's) are lighting fast and I know of no large driver ( we're talking 10" and above) subs that are quick enough to match these mains, so the REl was the answer . If one is looking for more extension and they have a larger room than I along with slower mains, then i suspect that most if not all of the larger Velodyn'e would be fine, just IMO.

One other thing that I forgot to mention in the Rel's favor....the hook-up scheme is IMO better than competing designs. The Neutrik connector allows a hi-level connection directly at the amp terminals, which allows the signal to be more precise to what the speakers are seeing at the amp terminals. I do think that this leads to a more "accurate" reproduction than taking the signal from the preamp, as in all other models that i am aware of......again, IMHO.

He's my dilemma: I already have one REL 505, and I can find another on 'Gon for about $1000. If I switch to the Velodyne DD12 (same piston size as the 505)I will want/need 2 and the cost will run to $3000+ if I buy them used.

My question is, will 2 DD15's truly outperform 2 505's? I mean hands down, no questions asked undeniably better?

Thanks,
Mike

Okay - just back from the Velodyne website where I found the Optimum 12. The Optimum 12 is a bit more than half the price of the DD12 plus - so what would I give up if I go with the Optimum 12 over the DD12? And is there any experience with the Opti 12?

Would the Opti 12 be considered better than the REL505?
