Possible components issues?

Recommended Posts

So I was looking at my new Crescendo Audio CCX65's and I noticed 2 possible issues I'd like feedback on.

Issue 1.

One of the crossovers is loose in its case and rattles around and can be moved around inside the case by pushing or pulling on the block. The other one is rock solid. Will this cause any issues other then an annoying rattle? If not I will just open the case and adhere it down like the solid one.

Issue 2.

One of the mids is not centered. I am not sure if this will rub or not during use since its not like these things have subwoofer excursion levels. I pushed the cone up and down a bit and didn't see or hear it rub. But I have a damping factor of about -6. So I could have been subconsciously biased and pushing away from the tight gap so it wouldn't rub. lol Aesthetically this one looks like ass. But I don't care as it will be behind the door panel. See photos below.

Perfectly centered mid. Note the nice even gap as it wraps around.

Mid that is way off center. Note how tight the gap is closest to the front. There is still a gap, but its a VERY small gap. Seems like the center piece is mounted crooked.

Extreme close up of the tight gap. Still looks like enough room to freely move.?

The exact opposite side of the tight gap. HUGE gap on this side.

And here is a shot of the full set just for fun.

First impressions are the build quality is pretty good. My only gripe so far, which isn't major, is the spring terminals are connected to the basket via a very narrow and thin piece of metal. I have seen numerous people say they busted it off the basket pushing them in to insert the speaker wire. So I'll be careful when wiring them up. I lightly tried pushing the spring up and the metal started to twist and bend a bit.

Paper thin metal holding it on. Looks a lot thicker via the camera because of the extreme close up.

Looking forward to installing them once I get my amp purchased. But for now, what say you about the issues?

Pretty sure that phase plug in the center is screwed in there maybe it is just bent. Email Crescendo and ask maybe you could just take it out and bend it slightly.

Open up the crossover and put some silicone to hold the card in place. (hope I understood that right that its lose in the case?)

Hot glue should be more than sufficient ;)

So, you come here and ask two questions that directly relate to build quality (one of which potentially impacts performance)....and then go on to say that build quality is good? You're much nicer than myself......LOL....strike one, maybe an oversight.....two strikes in the same set of speakers? -1 on QC IMO.

As to your questions;

1) Yes, I would recommend finding a way to secure the xover board. Help safeguard the components from being rattling loose a connection or solder joint.

2) If there is no obstruction to the cone movement, it won't pose an actual problem. However, you may be able to recenter it yourself if you know how they are attached. IIRC aren't those supposed to be able to converted into coaxials? If so, it should be pretty easy to remove the phase plug and recenter it if that's the issue. The other issue may be a mis-centered backplate which is throwing off the centering of the entire pole piece.....in which case, I'd be sending an email to the company about supplying a replacement driver.

Better idea.

LOL There is always a lemon in every group. I'm just luck enough to get 2. But the board could have been knocked loose via a clumsy fedex driver dropping the box. I'm a pretty mellow and laid back guy so everyone gets the same benefit of doubt. Intentionally screw me and I start breaking kneecaps. The build seems pretty beefy for a $100 bucks. I was honestly expecting much less.

So I'll shoot them an email and see what he says. They are convertible to coaxials so they do have a screw dead center on the motor. So hopefully its just a quick fix. As long as it functions properly and it doesn't rub, the phase plug could be upside down for all I care. lol

Thanks all for the recommendations! :drink40:

I wouldn't be worried about it being tight on my Bravox Mids the gap is just as tight as your first one. but... the one with the larger gap is odd... Is it that loose around the entire gold piece? or is it slightly closer to one side than the other?

First mid shown is fine. The second mid is tight on one side ( Pic 3 )and has a huge gap on the other side ( Pic 4 ). Messed with it a bit more and couldn't get it to rub. I think it will be fine but I'm shooting him an email anyways just to double check.

Seems like manufacturer error.

I am not a fan of the spring terminals on such a small speaker. I could see where it could get snapped off easily.

I would see what Crecsendo says about the phase plug issue. I know they have good customer service from reading on the company on another forum.
