Title: Subwoofer Buying Advice
Post by: Sam Lightfoot on March 21, 2013, 06:26:43 pm
Hi,

I am looking for a pair of subwoofers to go with my JBL PRX-635 tops (I have two).  I was tempted to go for the JBL PRX618-XLF's but the overall opinion on the reliability of the 600 series is not good, with many thermal issues and power supplies being damaged.

I have around 2000/$3000 to spend, and this can be stretched if needs be.

I'm not strictly looking for an active setup, so passive is an option.  I'd just like to get the best for my money.

Thanks.

Start at the beginning and work your way to the end. What do you actually need? What can you physically move around? What are your venues like for loading in/out? Are you happy with JBL product? Matched stacks are more pleasing to look at and easier to sell to clients......

I have no issues with transport and logistics.  Venues are always different so I imagine they can't be huge.  Yeah for me the 635's are top notch.  I'm very tempted to go for a pair of XLF's.

Here's what a 535 looks like over 2 K-subs.

I think the XLF's are the perfect match for 635's.  I've done a couple of gigs with that exact rig and was quite pleased with the results.

You are already kinda knee deep in PRX, might as well go all the way and get matching subs or get out altogether IMHO. While PRX 'issues' do seem to be quite talked about, I can't help but suspect that this is just a small group of problems 'going viral'. There's tons of PRX out there in the wild running awesome for a long time, and it's ways been good to me when I've mixed on it.

You could also get VRX918SP, more expensive but an industry standard and goes lower. I can't throw a stone without hitting VRX in my city.

Yes. I am very impressed with the marketing gurus at JBL.  They nailed it on several fronts with that series.

Well I can't afford the VRX subs, they are 2000 each in the UK, whereas the XLF's are 1150 each.  I am probably going to go for the XLF's.

Unlike many other components in the PRX 600 series line, the 618s XLF cabinets have generally gotten quite good reviews.  I've had problems with the 635 units you like so much (problem with the midrange horn's resonant frequency, which JBL fixed by gluing on a gasket), so YMMV (obviously).  I had problems with three of the four 625 cabinets I bought (blown amps), but they've worked fine since JBL repaired them.  Will definitely be looking at four 618s XLF cabinets and four 615 wedges later this year to complete my B rig.  My experiences haven't completely scared me away. :)
Cheers,

In the US those are the list price in dollars - $1150 and $2000. You should be able to get away with 2 of them from a professional dealer for about $3000 here, I thought it might be the same there. All good though - I think you'll be fine with the PRX.
