crossover rig question

[iamdenialNJ]

Hello amp forum. Here's my situation. I am running a 4 ohm ampeg 410hlf and planning to run either a 8ohm or 4 ohm 1x18 cab, it all depends what I find (let me know if there are advantages to each). I would like to run all the low freq's into the 1x18 and all the mids and highs on my 410hlf. How can I do this? I am currently running a shuttle 6.0 as a head. Thanks!

You're looking at biamping, which your Shuttle can't do.

You either need to split the signal before amplifying it then run two amps, (biamp enabled heads do this) or crossover the high power output of the amp (not advised unless you really know what you're doing, impedance issues, etc).

If you try to parallel another 4ohm cab you're going to risk nuking your shuttle.

Why would you even want to try ?

The HLF puts out plenty of lows, and would most likely suck at being the mid/high section of a bi-amped rig.

[BassmanPaul]

The average 15 or 18 single cabinet will not give you any more lows than the HLF. With what you currently have there is no way of driving another cabinet aside from using a second amp.

[BassmanPaul]

Another thought if I may. Buying a cabinet, or anything else, that becomes available is a waste of time and money unless you consider what you want that item to work with. For you even looking for another cabinet is pointless as you can't safely connect it.

[iamdenialNJ]

Hmm... ok. Yeah, the hlf pushes loads of lows but I'm running an octave down pedal for all my songs at at times the hlf farts out. That's why I want to run a 1x18. I just don't want to blow up my hlf. So klocwerk, should I find an amp that does enable biamping like say GK amp? What would you advise. I definitely want to run a 1x18 with my hlf.

You could get a power amp and hook it up to the direct out on the shuttle.
Just toss a crossover after the shuttle and before the power amp. Ashly xr series are pretty cheap on ebay.

Shuttle direct out -> Ashly xr crossover -> power amp -> 1x18

It would probably be cheaper than getting a new head.

Most 18 bass cabs aren't going to do anything the hlf can't do. You're already at your minimum ohms so you can't just chain along another cabs without getting another amp.

I'd just quit using the octaver thing, there aren't many cabs that can truly reproduce it anyway. That thing is a guitar effect.

This sounds like a possibility and then the hlf goes connected like normal right??

will33 I cannot quit the octaver thing. If that means I might have to sell my shuttle then so be it.

[iamdenialNJ]

Would it be easier if I just ditch the shuttle completely and then get a power amp + pre? or a amp that has biamp like a GK?

EDIT: THanks for all the responses for far. I appreciate it.

Yup.
But to completely eliminate lows going to the 4x10 a full byamp'ed setup might be the only answer. Eg, killing the lows via the shuttle will also kill the lows going to the direct out.

You would be using your shuttle as the pre. err well depending how you set the Pre/Post switch on the direct out of the shuttle.

If its easier to just get a new head go for it. ) I would totally understand. Dragging a rack around can get old.
I run a bi-amp setup and love it. But its really not for everyone. I get 99% of my sound from pedals so it works great for me.

Amp wise you could prolly find a cheap QSC rmx 850 on ebay. Bridged they put out 600 watts @ 8ohms -> $100-$200

An 18" cab is not going to help you. In fact, unless you want to start over with the entire rig, this is just an excersise in wheel spinning.
