Question Cab Question

[Mogee]

If I want to run two speaker cabs eventually, does that mean I will need two 4ohm cabs?

 

[maddog]

depends on the amp and how they are wired.

Usually hooked up in parallel. 2 4ohm cabs in parallel would be 2ohms, a hefty load for most any amp.

Best bet is to get 2 8 ohm cabs which would present a 4ohm load to the amp.

The Shuttle output is 375 watts at 8 ohms and 600 watts at 4 ohms, so you've got two ways to extract the full 600 watts - a single 4 ohm cab, or two 8 ohm cabs. With two 8 ohm cabs (of the same efficiency), each cab will pull 300 watts (ie. the 600 watt total will be split between the two cabs).

if youre planning to use 2 cabinets and not blowing your amp you should get 8ohm versions

Thanks a ton, I get that confused in my head. So, loudest would be a single 8 ohm cab? What would be the difference in sound from say a 4ohm 4x10 vs 2 8ohm 2x10s. I am a newb at bass rigs, so thanks for any input.

Almost...
As AussieMark wrote.

Generally speaking:
Loudest would be 4 ohm total because this brings the full 600W out of your Shuttle. If you achieve these 4 Ohms by connecting one 4 Ohm cabinet. or combining two 8Ohm cabs doesn't make a big deal of difference.

But: If you connect just one 8 Ohm cab your shuttle pumps "just" 375W into that cab.

Sound difference depends on a lot of things.
Due to the bigger housing 4x10s tend to pump out slightly more bottom end than two 2x10s, but thats very generally speaking and you shouldn't overestimate that.
It really depends on the specific cabs you're using.

I find having 2 smaller cabs simply gives you greater versatility. Leave one in the rehearsal room leave the other at home and so on...

So, I would probably get a lot more out of a 2x10 with a 1x12, then with just a 4x10 figuratively speaking.

Depends. Let's say your 2X10 8 Ohm cab can handle 300 watts, and the 1X12 8 Ohm cab handles 250 watts then your cabs combined can handle 550 watts; at 4 ohm the shuttle is capable of delivering 600 watts. My Bergantino AE 410 is a single 4 Ohm cabinet that can handle 800 watts.

The nice thing about having two cabs though, is that you can use a single one for practices and two for gigs (if required).

Assuming the cabs have similar specs, the 4x10 would be louder than running a 2x10 with a 1x12, because more air is being pushed. With the same amp at the same volume, the 4x10 would seem louder for that reason. A 4x10 vs a pair of 2x10 cabs, on the other hand, would be pushing the same amount of air.

I know some of you guys with the Shuttle 6.0 run a couple of 1x12 cabs, what about some of you markbass guys? The Littlemark is very similar. Have any of you experimented with anything other than a 4x10? Thanks for the help.

But how many watts a cab can handle doesn't say much about its efficency.

In fact. I always felt its quite the reverse. I always felt that I had to crank the Amp Volume on my former 700W 4x10 higher than on my 500W 4x10 to achieve to the same volume.

My experience:
Modern cabs that can handle a lot of power also need a fair bit of power to get the speakers moving.

Best thing to try a few different brands.
Reading specs is one thing. But hearing is just a lot better.

I'm running the Genz Uber 4 x 10 4 ohm cabinet with my Shuttle 6.0. Killer combination, IMO.

With my Little Mark II I run either 1 or 2 2x10 cabs. Sounds great.

Always good advice. I've played a LMII through the AE410 and I thought it had enough power to drive the cab, I haven't tried it with shuttle so I can't speak to that amp.
