I have a ported 410 , but on certain notes the crossover will vibrate so bad it overpowers the cab's sound, :scowl:

Does anyone know what i can do to stop this? The cab already has internal bracing and padding (RBH410)
And it only does it when i have it cranked

This thing sounds awsome otherwise, once I fix this issue i will be a happy camper :help:

Hot glue gun all the components down to the board - except resistors [make sure these are mechanically secure] - then a few dabs of hot glue on the backside of the board and then fix it in place with new screws one size larger in diameter [or toothpick shafts and a dab of carpentry glue in the old holes].

It could be a cracked track or wire, or a dry (cold) solder joint that is loosing contact when it vibrates.

As Bill says, take it back if it is a new cab, otherwise if none of the other suggestions work then get lots of light on the crossover and see if you can see anything wrong with the tracks (if a PCB), component leads, wiring and solder joints.

I have speakers patched with automotive silicone gasket maker stuff (RTV) years ago that are still in regular use. Maybe it does eventually deteriorate the paper but it must take a long time.


OP, plastic jackplate with a heavy board hanging off the back of it? May just not be mechanically strong enough, or cracked around a screw hole. If the cab is older/out of warranry, find a metal jackplate for it, or take the x-over board off the jack plate, screw it to the cab wall close to a brace, and run some wire from it to some new jacks you put in the jackplate.

I have used liquid neoprene rubber sealant for this kind of thing, a mercury marine product.
Used for sealing and encapsulation of Outboard motor and Z drive wiring looms, ignition systems and alternators, its very quick drying and so leaves very little residual solvent when dry, almost as heat resistant as Isobutylene-isoprene.

Its not a new cab- so i cant take it back, its not the components on the jackplate vibrating, its the entire thing rattling when i hit certain notes, i just need to figure out some way to stop the Crossover/jackplate from recieving so much vibration , i figure either a thick rubber seal might help or maybe some extra bracing around the crossover, but i didn't know if this has been done before or if someone has had this problem and did an easy fix
