Cabs for 2 ohm amp - a dilemma....

I think people are trying to give you input, and from a perspective of a lot of experience. The answer to your original question is that yes you can use two 4ohm cabs with a 2ohm capable amp without problems.

Whether that is a sensible thing to do is another question. Intuitively more watts means more volume but that isn't always what you'll find in practice. The second part of your question is how to sensibly go about getting more headroom for undistorted sound at high levels. The most reliable way of doing this is to look at doubling your speakers up. Adding a 2x10 to an existing 2x10 at the same amp power will give you an extra 3dB, that's exactly like doubling the amp power. Adding a 4x10 to another 4x10 will add 3db, also the same as doubling the power so an 8x10 is going to be 6dB louder than a 2x10 using the same speakers. That's the equivalent of moving from a 300W amp to a 1200W amp. Go on adding 8x10's and your amp will eventually fill any space

The other thing is that the power supply in your amp isn't up to running at 2ohms. The power should double when you halve the ohms but in your amp it won't because it's 'engine' isn't big enough. In practice if you drive it hard at 2ohms it will heat up and become less efficient, it'll slow down on the hills to extend the car analogy.

The other thing is that volume isn't everything, it still has to sound good.

All people are trying to say is that 300W should be enough, not all speakers are equally loud but choosing wisely and doubling up is the way to go. Going down to 2ohms is usually a sign that you've started from the wrong place.

Thanks for that ,the quote you gave of mine was specific to one answer .Everyone else has been helpful .I'll just add again my amp is 2ohm ,I run 2 4ohm 2x10 with it 

Great sound just heavy so looking to get decent lightweight options

I think (linked to alexs post) you would be better with say x2 4x10 at 8ohm each, rather than x2 2x10 at 4ohm each.

Even if my amp ran down to 2ohm, i dont think id ever run it at that. 4ohm is plenty.

My car and my back says no to 2 X 410 cabs ! Thanks all the same

Email Alex at Barefaced. If he can't put a smile on your face a mile wide and save your back at the same time you should be playing a flute.

      I have recently acquired a Barefaced 210s and Ashdown ABM Evo iv 600W
      Its plenty loud enough for most situations (I do think its as loud as a good 410 as advertising suggests). On the rare occasions when I have a bigger gig with no PA support I intend to pair it with another cab. I have an ampeg 410 that I can pair it with, but I'm considering replacing that with another Barefaced 210s.
      A Barefaced 210s can run at 4ohms or 12 ohms. The ashdown head can push 600w at 4ohms. So a single cab can potentially receive the the full 600w from the amp.
      If I run 2 cabs, Ill need to switch the cabs to 12ohms, So I'm guessing I could be pushing around 450w split between both cabs at 6ohms. 
      Therefore is the potential volume of a cab on its own is way more than that of a paired cab?
      Would 300w to a single cab, be half as loud as 600w (is it linear)?
      What is potential volume increase as a percentage if I run a second cab?
      Hopefully the above makes sense.
      Thanks

      Barefaced generation 3 big baby 2 for trade.
      very good condition, it’s been my home practice cab- see photos for condition  
      steel grill version.
      Looking to trade for a lightweight 2x10 cab, particularly interested in a barefaced 210s or a berg 210hdn

      Well respected octave pedal.
      couple of marks here and there, all superficial. Seem to have misplaced a couple of the screws that on the bottom but the ones left are more than up to the task.
      That weird foam backing same as all EBS pedals but Velcro seems to stick to it OK.
      £70 delivered or collect from East Herts. Trade for another octave, COG t-16, Boss OC-2, etc.

      We all know how good these are. 🙂
      Excellent condition and comes with a padded cover. Only selling as I'm switching to IEM & preamp pedal for live shows. 
      Collection from South Beds. I'd prefer not to post.
      No trades. 
      Thanks.
