RT800i problem - *noobie*

[ffej0872]

Yes, noobie - be gentle.

I have a pair of RT800i that I am having problems with.

I've had these for a few years (i'm sure I'm up against an expiring warranty) and only had one problem previous to today. I had a warranty replacement of a driver whose cone had separated. Now the same speaker has a roasted tweeter (OEM tri lam).

Should I replace with silk dome?

Might there be a crossover issue?

Aside, thinking of picking up RTi4 as rear surround, thoughts?

What are you using for power and how loud do you play it?

[ben62670]

Your crossover is not to blame. I can almost guaranty that you are trying to play them to loud without enough power. Not enough power frys tweeters way more than lots of clean power. RTi4's should work fine. Call Polk customer service and they might send you another replacement.

Oops! I guess I did forget to mention:

I'm running a Yamaha RXV2500. And I do like it loud. But not enough power?

[F1nut]

But not enough power?

Right. Clipping is your word for today.

Right. Clipping is your word for today.


Thanks. After a bit of research <shame>, I don't like that word. (will now refer to it as the 'C'-word.)

Now that the yammie, that I thought was quality, has been identified as shite, how do I determine when the 'C'-word initiates?

No one said it was shit, just that you're pushing it into clipping. There are few amps (not AVR's, they all clip) that can't be pushed into clipping. Think of it like the redline limit of an engine. Some redline at 6K and others like F1 engines redline at 19K. Go past the limit and you've got trouble.

Anyway, some signs of clipping would be a noticeable compression of the music, highs that hurt your ears, loss of bass control, etc.

A general guideline, near and over halfway on the volume control will get you into clipping.
