How to stop Amp Head bouncing around

[steven_awc]

This weekend I finally got to test my new Redsub 500W 4x10" cab and head. After a while I started to get the hang of how to set it up and despite being a pretty much unheard of make, it sounds quite.

I have two questions, the head was moving around sometimes if there was too much bass coming from the cab so how do I stop this from happening. I obviously don't want to be keeping it still when I play at live gigs all the time.

Second question, the power light is usually green until I seemingly turn the gain up too high and it turns red. What does this indicate?

Thanks everyone, Steve

Try placing a small piece of foam between the cab and head.

The rolls of kitchen drawer liner work well too.

Or get a properly designed and built cab, short of that brace the cab you have and add batting. Energy from the speakers is wasted when the cab vibrates like that.

Duct tape.

My Barefaced Big Twin is impressive - even the little GK MB800 sits perfectly still on top of it, no matter how loud I play. So +1.

Or Velcro?

Brace the cab effectively on the inside.

I just took a look at your units using the power of the internet. I assume you have the 410 cab?

Few dumb things going on with this product. First, the cab is 500w at 4 to pair with a 500w head. That's borderline grim. It's a pity they didn't engineer that cab with a bit of extra power handling behind it. Be careful what you throw at that. If you're aggressive you're liable to pop speakers. That's probably why it's vibrating so hard. You're quite possibly giving it all it can handle which is a poor design decision.

Second, and most importantly, the head has a smooth surface and the cab appears to be standard ratfur. There's no feet on the head and so clearly it's not got enough friction to stop it from sliding away. Equally dumb is that they don't seem to sell rack ears for that amp so you can't even put it in a rack unit easily. That would turn me off it immediately.

I would suggest you send an email to the supplier and ask what rack ears (if any) fit the head. Then you should order them out and get a cheap rack unit on the second hand market. This will stop your head sliding off (because most racks have non slip feet) and it will also protect the head from stupid accidents. Heads of that design style belong in rack units. It will probably all up cost you an extra 100 but the alternative is far worse; trust me, I've done that.

I'm assuming because you went for a budget line amp setup that you're probably not in the market for a new boutique level cab right now.

I throw a car mat between the head and cab.

Hi.

OP, as You can see, there's two schools of thought at play here.

One is to ignore the flaw in the cab design and just band-aid the cause.

The other is to adress the cause and make Your rig louder and more efficient.

Take Your pick .

Boom. Peel and stick on the bottom of the head.

Use a folded towell between the head and the cab. Another option would be to buy an expensive doormat and cut it down to size. I've seen another bassplayer use a piece of doormat.

That light turning red is probably the limiter coming
on when the amp starts clipping.

Don't do that!!! Back off!!! If the amp is actually
pushing 500 watts, it could damage a cab that is
only rated at 500 watts.

Don't mind these guys. They may think if it's got
the wrong name on it, there has to be something
wrong with it.

Mat that head and back off a little. Maybe just use
less bass. The rest; if it ain't broke, don't fix it,

I'd suggest that the red light is a limiter too. Read the owners manual OP and then you tell us.

I believe the only way for the Amp to put out a true 500w would be for the OP to turn up every knob to full and push up all the sliders to the top. It's unlikely that anyone with the slightest shred of sense would do this but stranger things have still happened. While I think it was a dull thing for this company to do the 500w cab is theoretically pretty safe. If it does turn out that the red light is a limiter that's probably the exact reason it's there: to guard against people who turn the bass sliders up too high and/or run hot preamps in their instrument.

But seeing what price point these things are selling for, you got what you paid for. Is there time left to return it for a refund?

 

[steven_awc]

Thanks for the feedback everyone, I have asked to return the cab and head because I dont know how to avoid hitting the limiter so frequently. The amp isnt loud enough to be heard over drums without hitting the limiter. The big problem I have is that someone chose to through away the packaging for my amp and Im probably not going to be able to return it now.

Can anyone lend some advice on how to set the head up better to avoid blowing the cab while still getting a loud enough sound?

Lower the bass and punch tha mid range,

Place the cab on top of the head.
