Seriously budget subs

Recommended Posts

Does anyone have any recommendations please for seriously budget subwoofers - these are for school discos essentially, we have EV ZLX12 tops, and currently we pair them up with some HK subs off a L5 system, but need something dedicated to use with these.

 

The matching ELX118 are £500 a piece, whereas things like the Thomann Box stuff can be as little as £210. Skytec have active 15s for as little as £85 a piece(!) but they surely must be shocking.

 

Need to be able to pole mount the 12" tops over them, and they are more for stands and look than sound. I'm guessing used off eBay might be better for this one as it'll stretch the money a little further.

How noisy are the fans in the alto subs? It's not a major issue for disco but I spotted a pair of do Opera subs for cheap but thought the fans seemed unusual.

 

That said, we used power amps with fans in the room for years and never gave it a second thought.

Can't hear them at all. No issue.

I've got a pair of TS Sub15s now - the fans seem to be temperature controlled, which I hadn't assumed they'd be at the price point.

 

Only weird thing is the castor mountings are on the bottom - I know they're only small subs but we'll still castor them - is that standard? These were a 'lightly' used pair (they must have been taken to a lot of gigs they weren't used on!) so it's possible someone's fitted those nuts afterwards but it doesn't look like it.

Managed to fit some castors on the back, although it's very tight as the active plate is quite wide, so it forces the castor so close to the vertical edge that the castor hole pretty much touches the side wall - so you won't get a T-nut on - but can get a normal nut on (just) if you gouge into the side a bit.

 

Subs have good output (once I'd realised the SIGNAL LIMIT led turns green with signal and turns red with limit - rather than just illuminating for limit - I though they were running into limit really low but that's just signal indication.)

The only thing is they need a reasonable input signal to drive them - a lot of our setups are small active systems played directly from laptops and phones - which doesn't have quite enough output to drive them properly - at maximum input sensitivity you still seem to run out of input signal before you've managed to really push them. I'll have a look into this but one cheeky suggestion I found online so far is just to link from the link output from the first channel back into the 2nd input - should buy 3db at least.

 

Oh - I also swapped the pole mounts for M20 screw style - but that's just a personal preference. I never seem to get on with straight socket type as there are a few variations in size so they seem to get stuck. Was a straight swap for the Pulse branded ones from CPC for less than about £3 each.
