4ohm or 8ohm?


Recommended Posts

I have a bass player who has (finally) blown up his 1x15 cab - open circuit 400W 15" 8ohm speaker. Would I be better replacing this with a 4 ohm speaker? Would this be more or less likely to fail?


He's driving this with a Peavey PV 1500, so (allegedly) 300W per channel at 8 ohms; or 500 watts at 4 ohms. The amp has (DDT) soft limiter switched on, which I suspect is having to work overtime.


Finally, is there any harm in driving on side of the amp in to 4ohms and the other side in to 8ohms? Thanks!

If you go 4 ohms, your bassist will gain headroom and maybe less likely to drive the cab hard?


No problem with a 4 and 8 ohm impedance difference, though I'd be inclined to bridge the pv1500 and use solely for the bass player.

You will notice the red led on all of the time if the ddt is working overtime.

And/or noticeable distortion.
