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.

[Happy Jack]

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.

[Happy Jack]

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.

 

[Phil Starr]

I think you will be fine. Our ears aren't great at hearing sub 120Hz so the quality of the subs is going to be less than crucial. I've done gigs at excruciating sound levels with some ancient JBL 125W subs and they did add something and spared the tops a little too, so job done. If you bought these online then you've got a return period to reject it and a chance to try it out at home so the risks are almost zero.

 

Is Sylvie able to record some of the gig? it would be great to know how you get on with the sub, on spec it is the bargain of the moment. It might be a great cab to mod too. For well under £100 you could put in a reasonable neo driver and maybe save a kilo or two whilst improving the performance. Anyway I'd love to know how you get on with it. Hope it works out

Appreciate that @Happy Jack was already sorted before I happened on his thread, however also an ongoing topic of interest for me! I've come across 3 subs which could also tick the box, which may be of wider interest:

 

Behringer B1200D Pro - 500 W RMS 19.5kg / 43 lbs £239

Subzero 2 x 10 - 600W RMS (I've asked G4M for the weight) - normally £500, currently on sale at £380

dB Tech 612 - 600W 19.8kg / 44 lbs £395

 

No idea how decent any of these are, so if anyone has had experience of any of these, I'd be very interested to know?

@Silvia Bluejay won't be at the next Load Of Hay gig but she will be at the one I mentioned and she will be recording it, so that should be very doable.

Pretty sure that's 21Kg.

Thanks - doesn't seem to be any info online? But, if that's the case, that could make it a serious contender with 2 speakers each delivering 600W RMS.

 

Scrap that, apparently the power module delivers 600W RMS so that will be split between the two speakers, and its claim of 2,400W peak is pretty far-fetched.

Bit of a misleading question then, asking us "does such a thing as a decent, lightweight sub-woofer actually exist?". I took "decent" to mean "capable" (not an unreasonable assumption), but it turns out you don't actually need 'capable'. Silly me, eh?

 

I'm impressed that you posted yesterday, then managed to do "a lot of research" and also buy a sub, all in the space of 24 hours. Why bother asking on here in that case?

 

Had you told us you already had a MarkAudio sub', we'd have likely suggested sticking with that (I would). 23kg is hardly a behemoth. I'm 72 and have no trouble schlepping my Fohhn XS22, at 25kg.
