Two 4 ohm cabs.

[MarshallBTB]

I'm after a head that can run two 4ohm cabs, maybe something like the Ashdown LG1000.
I like the specs but keep reading about problems with it. What else does 2x4ohm outputs/goes to 2ohms?

[bassmachine2112]

marshall mb450 head runs 2x4 ohm cabs all day.

[Mr. Foxen]

Plenty of peavey amps do 2 ohm. And plenty of PA type power amps.

[TomTFS]

Most Edens will, plus valve Ampegs (not sure on the SS ones).

[Musicman20]

Genz Shuttle Max 12.0. Two sides minimum 4 ohms.

[xgsjx]

EBS?

[markstuk]

EA's run 2 ohms, as does the TC Blacksmith. Plus any power amp worth it's salt (I've a QSC2402 I use for 2 4 Ohm EBS 410's)...

Get a special cable to run em in series and they will be 8 ohms together which will work through any amp! Then you can get another 2 of the same cabs and build a wall of doom.

What cable would this be?

[TimR]

Indeed. Why do you need to run them in Parallel? Assuming they are identical cabs you can run them in series. If not then you'll need to parallel them up and even then you might not get the results you are after.

Not the SVT.

This.


Plus that parallel cable would be a dodgy cable as you'd need to make a half Y-split kinda affair. So it's going to have 3 ends. I definitely wouldn't trust it with any of my amps, far too easy to short out.

[malcolm.mcintyre]

Running them in series will work with any amp, but be prepared for them to sound significantly quieter than one cab on its own. If you want the two cabs to be louder, you need to run in parallel from a 2 ohm amp. I bought an Aguilar DB751 for that very purpose.

The LG1000 is an okay head, just not great, if you know what I mean. The Superfly is a superb head if you can get one as well. What about the newer MiBass heads from Ashdown, will the bigger one run two four ohm cabs?

[razze06]

Peavey Mark III (or IV) 400.

Not only will it run 2 ohm loads, but it will crack windows 300 yards away at half volume, and cook your breakfast on the heat sink.
All this for less than £100

[MarshallBTB]

Thanks for the replys! Not looked at the Mibass or Superfly stuff. Moneys an issue at the moment, and I've used peavey gear in the past and loved it so I may check that out.
Don't think running them series is a good idea as the cabs are different.

[Krysbass]

The Carvin BX500 also goes down to 2 ohms. I haven't yet tried one myself, but this could well be my next amp, as I want to keep using my existing 4 ohm cabs.

I've been using an Ashdown LG1000 for about 18 months now for all my band rehearsals and gigs and never had any problems with it. I use it with 2 x Yamaha 2x10's (stacked on end of course).

[MoonBassAlpha]

There's a Superfly going for £120 on Oxford's Nightshift message board:

seems a good deal, and exactly what you're after! You might need to read some threads about how to run them without overheating, but still.
Bargain!

why? More air being moved.....

[dudewheresmybass]

The Marshall vba and DBS 7400 will run a 2 ohm load with no issues
I use two 4 ohm Marshall cabs and either a hartke lh500 or Marshall 7200 DBS head (which need a maximum 4 ohm load) with a cable that runs the cabs in what was described to me as series parallel. Apparently the heads 'sees' a load of something around 6 ohms. This is what my amp tech tells me!

Most of the high end SVT's

[Lfalex v1.1]

Hi there, mate!
Power amps. Nearly all will accomodate a 2Ohm load, but not in "bridged mode", so you'll have to run it via just one channel (assuming it's a two channel power amp, which most are)
In Bridged mode, the minimum load most will tolerate is 4Ohm. As for heads, I have no idea!

+1

You'd actually get about 1dB increase in volume, although in the real world that equates to no difference at all.

[ThomBassmonkey]

The GK 2001RB-II is 2ohm per side, so you can run 4 4ohm cabs if you wish..

[Raslee]

As someone mentioned here you can get a series cable to make 2x4ohm cabs become 8ohms, OBBM on here makes these cables - very sturdy too. I can run two 4ohm cabs in series on My Orange Terror bass when it is switched to the 8ohm setting and still get the 500W as the amp runs at 500W both 4ohm & 8ohm settings.

For flexibility i can run just one of my 4ohm cabs on the Orange terror bass in the 4ohm setting at still get the 500W. The Oranges capability of running full power at 8ohms plus a very well made series cable which cost me something like £30 ish give's me great flexibility, portability and most important still get the power.

Having said all that the Terror bass is quite a specific valvey ballsey sound, dare i say 'one trick pony', ...but i really like it for my sound. From the other amps mentioned i highly rate the Eden amps; the Eden WT550 does 2ohms whereas IIRC the WT800 does 2 channels both capable of 4ohms - great sounding amps IMO
