Lightweight Sub-Woofers

[Happy Jack]

OK, OK, I realise that this is pretty much a contradiction in terms, but does such a thing as a decent, lightweight sub-woofer actually exist?

 

I am NOT interested in sooper-dooper FRFR systems ... I am after a sub that I can use with a pair of QSC CP8s in small pubs & clubs, something that weighs less than 40lbs, something that will not be used at very high volumes but needs to cope with a low B without blinking (or melting).

Wharfedale Pro T-Sub AX12 21Kgs or 46lbs. They are made to match their Typhon 8AXF which has a similar spec to your QSCs.

How much do you want to spend? The rule is light, capable, cheap - pick any two. QSC, RCF, Yamaha and others offer quality lightweight subs, but they aren't cheap.

After a lot of research, I went uber-cheap.

I don't actually need 'capable' and I already own more high-quality PA kit than is good for a man; what I need is 'suitable for tiny playing areas, usually in venues with lousy acoustics' where all that matters is form factor and (above all) light weight.

 

I'd never take a Citronic 1x10 sub to a serious gig, given that I already own two 2x10 subs and a 1x15 sub, and more importantly most of my gigs have no need for a sub-woofer at all. But I always have a benchmark tiny pub in mind, the sort of place where there's nowhere near enough room for the band / there's a 5'7" ceiling / the bar is five feet in front of the band / the load-in is a complete nightmare. My benchmark used to be The Red Lion in Leighton Buzzard, then it was The White Hart in Chalfont St Peter, and now it's The Load Of Hay in Bushey Heath.

 

Places like this need tiny speakers for all sorts of reasons, so I can use my QSC CP8 monitor wedges as PA tops instead but obvs they really don't handle bass very well. A tiny, lightweight, lowish-quality sub is exactly what I need to re-balance the system. @Chienmortbb suggested the Wharfdale and I'm actually a fan of their stuff but it weighs 21Kg so is only marginally lighter than the 23Kg MarkAudio units I already have.

 

Where the Citronix scores is that it weighs just over 16Kg. Because of the handle placement it's still a 2-handed lift, but a very easy one. I can still manage the Mark Audio units but it's getting harder every year to lift those buggers into the back of the car and then manoevre them around. 🙄

Have you already bought? If so it's too late but looking at this makes me ask the question is a cheap 10" speaker actually going to be 'better' than the two good quality 8's you have in the QSC's?

 

My thinking is that this cab is made of MDF which is excellent for cabs but just about the heaviest material you could use so that it means the speaker has a reasonably lightweight magnet. To get decent efficiency and low frequency extension you kind of need a big magnet. I haven't got time at the moment but could look at the QSC's to see if they might not do the job alone without the subs. I've used them at open mics for bass and been surprised at how capable they are. My thinking is that these tiny pubs (and I have my own in mind, The Green Dragon) often are pretty awful spaces and deep bass is unwanted. Cramped spaces means you are up against walls and low ceilings which reinforce the bass as well as turning it to mush.

 

Basically I can put in some specs for a decent 8 and a cheap 10 into winISD and speculate upon which might do best with bass. If you've already bought then just trying them out would be better of course.

Already bought Phil, and with my eyes wide open. If I've screwed up then at least I can't lose too much money on a £200 sub. 😉

 

We've used the CP8s at The Load Of Hay once already and it's pretty clear that they're on the lightweight side ... not a criticism, just recognition that we're deliberately 'mis-using' them.

 

We have a gig next weekend at a much larger pub but one where the space allotted to the band is about as big as your dining table, so I really wanted to get the sub on board in time for that gig.
