Title: Lightweight active 12 subs. FBT Subline 112sa vs RCF 702asII or other?
Post by: Richard Penrose on April 29, 2021, 02:40:34 am
Hi,

Im interested in getting some lightweight active 12 subs and the FBT Subline 112sa and RCF702asII are top of my list under 800.
The RCF has a max spl of 129dB and the FBT goes to 133dB but I dont know how this was measured.

Has anyone heard both of these subs?
If there anything else you could recommend around this price that weighs around 22kg or less?

What drivers do they use?

Max SPL numbers are pretty much meaningless.

What do the frequency response graphs look like?  Sometimes you get more bass from the main speakers than a baby "subwoofer". 

Why a 12" driver?  Driver diameter doesn't equal performance level.

Hi,

Im not sure what the models of the drivers are in these.

I specified a 12 because of size and weight. Ive been using a pair of QSC KW181s with a pair of Yamaha DXR15s but I dont really need a pa this size anymore as Im mostly doing acoustic gigs.
I just use the DXR15s by themselves these days and Ive been able to put a little kick and bass through them. Ive even run a fully miked kit through them on a few occasions and the DXR15s did a surprisingly good job.

I was considering getting a small system like the FBT VN2000 or a pair of RCF HD10s over the 702asII subs as I would expect this to outperform a single pair of DXR15s whilst keeping the weight and size down?

I bought a pair of SUB 702-AS II last year to use with the wedding band I run sound for. Have been using SUB-905AS MKII and very happy with them, but in some venues they are overkill and we don't have the space for both of them. I've been very impressed with the 702's, and while they certainly don't thump like the 905's, they are so small and so light that I can overlook the lack of whack. Granted, I'm doing mostly weddings, and this isn't a concert. But for smaller rooms they are awesome. I'm running a pair of EAW RS123's on top and the rig can get fairly loud.

Nice looking rig.   I personally would have my tops on tripods and use scrim for the wedding look.     Those tops look a bit large to be supported by such a small base.  I've done some high wind events where that would scare me... not to mention the occasional drunk-fest (um, enthusiastic drinking) wedding...

I understand the scrim comment, but I hate those things.
As long as the person paying me (band leader) is okay without them, I certainly am.
The tops are surprisingly light and the whole shebang is pretty stable. I do keep my eyes peeled for drunken Uncles and such and shoo them away as much as possible.
We are never outside, always in a tent or indoors. That's in the contract.

Thanks for sharing this  :)

I noticed that RCF released a new 9-Series plus NX-9 series and have updated their D-Line series and am now wondering if RCF will also be updating their Sub series soon? It would make sense for them to update the Sub range with the improved amp modules dsp and drivers along with the new RCF logo. I'm going to wait to see if there will be a new improved 12" sub.
