Push the center of the cone and listen for a metallic noise. If the metallic noise is present then the driver is bad. Also, if you can, make a recording of the rattling noise and send it to me and Brian so we can listen to it and find out what the problem is.

Just a Yamaha HTIB sub which I actually never used - just left it off.

Normally I'd say I'd be suprised if you could hurt that sub but with that stupid scene/intro anything is possible.

It's kinda cool I guess to demo but that intro is just plain stupid and dangerous.

Completely agree! Like why the heck would they put that stupid tone in there when it can ruin expensive equipment?! Maybe I shouldn't have been running the sub as hot as i was, but I had watched a whole bunch of movies known for LFE up until that point with no problem, so how would I know that some random tone that plays, before the movie even starts mind you, would blow a fuse and damage my sub. Not 100% at this point whether it's damaged, but I am thinking it is. The rattles its making were NOT there before this happened. https://1drv.ms/u/s!AqCwvEUzj5tPn2oZ6-DggICC5QIY"]Listen here.

Ya if I'm hearing that correctly something definatly sounds off.

That's another problem with that scene is that it's right at the beginning with no warning of how loud it will be.

Don't blame it on the lv12r as it is one heck of a sub! Could happen to any subwoofer.

I played my lv12r a couple weeks ago pretty hard. All the sudden I heard a bunch of rattling and thought something blew. Turns out an old popcorn kernel got in there somehow.

Anyway it might sound silly and idk if you have kids but make sure nothing got into the port

I listened to it, same for Brian and we agree that it could be also the amp. The fact that the amp blew a fuse during that scene is an indication that something went wrong with the amp. If you push the driver cone and there is no rattling noise then most probably is the amp. You can also check inside to see if there is a loose wire touching the braces. We cover the wires with polyfill but sometimes the polyfill get loose and the wires touch the braces or even the back of the cone making that kind of weird noises, most after a scene like the one from EOT. Feel free to take the driver out of the box and check inside. You can also test the driver with your front speakers wires and if you get sound with no rattling then the driver is fine.

I'll do this as soon as I get home. The Amp didn't blow a fuse, the subwoofer did. Where you plug the power into the back of the subwoofer, I found that little compartment under it and when i pulled it out I saw that it was that Fuse that was blown. I noticed this yesterday as I was about to take the back off to look at the driver. I had a bunch of screws out at this point. I actually never took the back off because I noticed this compartment and the blown fuse before I got all the screws out. Come to think of it, a couple of the smaller middle screws did not "catch" when i tried to put them back in, the ones around the outside of the back plate definitely did, so the plate is definitely secure. Any idea why those middle screws felt like they were just turning in place when I tried to screw them back in?

He's referring to the sub plate amp, not the amps in your AVR. The AVR sub pre-out doesn't power the subwoofer cone, the sub plate amp does.

Nothing wrong with updating us of the situation here, but be sure to talk directly to Brian and Enrico so you can get this issue sorted out.

Also this happened to be and it turned out to be the mental spike feets which are a pain in the butt because they rattle out of place if not screwed in with the strength of the hulk😂 so if anything check that to make sure.

Just talked to Brian who was very helpful - we have an action plan now - seems I may have loosened a screw or two from the middle of the amp plate not realizing it wasn't holding the amp on (sub amp, got it, duh on me). That screw has a nut on the other side which may have fallen into the woofer. When I get home I'll be trying to take the amp out, find the nuts, remount, and see how we do.

Those middle screws hold the big transformer and they have nuts on the inside so either a nut went inside the driver basket or the transformer is loose and causing the rattling noise.

I thought something sounded like a rattle rather then a blown driver or anything.

Let's hope it's just a nut! Shouldn't be to hard to track down

Good luck, sounds like something easy to fix.

Rythmik Setup Guides

Well, I've taken the plunge - I'm joining team Rythmik. I have a sub (FV15HP) on the way, my old sub has been sold, and I'm looking ahead to the set up process.

I've been looking for all the Rythmik specific setup documentation that I can find in this thread and on the Rythmik site. So far I've found, in addition to various posts I've bookmarked over the last month or two of watching the thread, the following guides:

laulau's guide
Guides from Enrico/Rythmik here

Are there any other Rythmik specific setup docs that anyone would recommend?

I think laulau's guide is all you need. It covers basically all Rythmik models, Audyssey and REW as well. One of the most important parts is the subwoofer crawl. There is no external DSP or room correction system capable to fix a bad subwoofer location.

Nice to see the limiter is now separate from the power switch.

By the way, that's a lot of knobs and switches. The compact amp is much simpler.

By the way, that's a lot of knobs and switches. The compact amp is much simpler.
The Limiter is in a separate switch only on XLR2 and XLR3 amps. PEQ3 amp still has the Limiter on the Power switch.

Nice, I didn't even notice that. I like seeing the limiter separate as well

In an attempt to "fix it" yesterday since it wouldn't even turn on I started unscrewing ALL the screws on the back not realizing only the ones around the perimeter were needed to remove to get the amp plate out. I loosened 4 perimeter screws and the two screws you see in the above photo before noticing the compartment under the power input which holds the fuse (shown below for anyone interested).






Once I realized it was just a blown fuse in secured the 4 or so perimeter screws I had removed and tried to secure the 2 in this photo but they just spin in place once all the way in. I was told today they might be screws with nuts on the other side so I took the amp plate completely off to see if I could find the nuts (which I thought might be causing my rattle). Turns out they don't look like but screws but are holding on the pictured component (transformer?) They won't tighten though still. That's what I need help with.

Use two philips screwdrivers. One inside and one outside. It is like tightening a nut and bolt with two wrenches.
