Only someone who doesn't play out much, would think about bridging 4x CS1000x into 4x boxes.

Who said 4050HD, has enough power to power 4x cabs !?
Maybe if in a wine bar, maybe.

Get another 4050HD, bridge 2x cabs per amp, and then you have just started to hear sub.

I have a QSC 5050 for sale, that will sound much better than your 4050HD, on 4x subs.

PM me, if interested.

You can't bridge two double 18" subs on an RMX4050HD, my subs are rated at 1,600 watts RMS and are 4 ohms.

I'd not hear a difference because the RMX5050 specs stated it only outputs 200 watts RMS more per channel and that would yield an extra 0.4db output not even anywhere near noticeable.

Just noticed your post said 2x 4050HD driving 4x 2x18s.

Pair of 5050 amps, driving pair of cabs each, would definitely do all you need.

But the audible difference would be barely noticeable and so it's no way near worth the cost.

Which drivers do you have in the cabs?

They're custom EV QRX218 style subs loaded with RCF L18P300 drivers, i've had them a few years now. I've spoken to a few people on other pro sound forums and they're coming to the same conclusion that the difference between the RMX4050HD and the RMX5050 in terms of capable spl from the subs is amazingly minimal, in theory less than 1db more spl.

I basically don't rate 2x18 reflex, as it's always the same story, people needing more and more power to drive them, due to very low efficiency.

Get yourself a Powersoft K20 or MC2 E90, and your problems are solved, 2x 2x18 cabs per channel no sweat.

However if you don't often play in venues with proper mains supply, you will suffer.

You might be able to afford a K20 but I can't, it took me two years to save up enough money to build my system that I have, then I got laid off from work and have started on Universal Credit which is piss all money to live on. So now i'll be lucky if I can afford £350 for an amp. But i'm not selling my system no way i've got the amps to power it all still but i'm wondering whether it'd be an advantage in terms of low frequency output changing from two RMX4050HD amps to power my subs to four Peavey CS1000x bridged.
