Hi everyone!

I've done a LOT of reading on this forum, specifically around how to improve the sound and kill the vibration in the soundbar. There is a lot of conflicting advice , so I'm asking for clarification from those in the know. The way I read it is that people have "fixed" their soundbar in any one of the following ways:

1. Dynamat the whole bar
2. Stuff the bar with polyfill
3. Fill the bar with expanding foam (ala "Great Stuff")
4. Drill venting holes to aleviate the sound pressure causing the vibration

I'm looking for the right one. Do I want to take the whole bar apart and Dynamat it? No, but if it's the right way to solve the issue I will.

Looking forward to your sage advice...

Start with good speakers...a lot of people stuff the soundbar pretty tight with polyfill

I did it on one side and I can't tell the difference

I put some marine Polk audio in the sound bar and it still sounds like poop.. I need a fix for this as well?

 

JBL GTO628's are on standby awaiting the soundbar fix answer.

 

last weekend I put a large piece of dynamatt behind each speaker and stuffed the bar with polyfil... I did hear an improvement, but nothing mind blowing. At this point, I could add more dynamatt and poly, but if I decide I need more from the speakers, I'm just going to replace them. For the $30 I spent on polyfil and quick roof, I'd say it was worth the money and my time to do the sound bar and Sub enclosure.

 

I grabbed an old pillow, ripped it apart, pulled the speakers out of the soundbar, and stuffed it to the brim with the stuffing. Sounds great and the vibration is gone. It helps to have small hands pack in the polyfil near the domelight.

 

I thought the soundbar was pretty worthless myself so I dropped in a pair of focal 6.5's and I still wasn't impressed. Took some polyfill and loosely stuffed the bar. Slight difference but nothing to write home about. Worth the $5 i guess. Anyway It wasn't untill I popped in a new Pioneer Head Unit (AVH-P4300) did it really shine. From what I've read on this forum the factory limits the power to the soundbar from the head unit and there's no fix but to replace it. Supposedly it was to prevent complaints of soundbar rattling (instead of actually making a better soundbar). I don't really crank it until the doors and roof are off and by that time there's no way I could tell if the soundbar is rattling anyway.

By the way, the focals do not fit the soundbar. Too deep. Had to build an adapter plate. Downside is I now have much better sound coming from behind me and will now have to invest in components for the front which I had hoped to avoid.

 

Don't be scared to do the front because of what you read on this forum. I did the front with no problem just remember on the drivers side the plastic dash is very very bendable. I would definitely suggest changeling them huge improvement.

 

Another pair of GTO628's are arriving for the fronts. I'll do those next weekend. I already have a Pioneer AVH-P3300BT installed. I'm putting in the GTO's to see how sound improves to determine if I get a mono sub amp for a 10" sub or if I get a 5-channel amp to drive everything.

So far, two votes for poly....

 

I think I'm planning on dynamat and then some fill. I have Focal 165V2 components I'm putting in the front, and need a pair of coaxials for the sound bar. was thinking of the Focal's, or maybe just get a pair of GTO's
