  • JBL SRX set VS KV2 EX set

    I know that passive and active speakers are 2 different worlds, but just based on quality and volume, how would you compare the two following setups. Also how big of a crowd do you think each setup should be able to handle?

    1. 2 JBL SRX728's powered by a Crown I-Tech6000 in stereo(3000watt/box)
    2 JBL SRX722's bi-amp's(I-Tech4000 in stereo for bottoms, xti-1000 in stereo for highs)
    A dbx driverack for all the processing


    2. 2 KV2 EX2.5's for subs
    2 KV2 EX12's for mains
    dbx active speaker driverack for all processing

    Well I can compare 4 SRX718S's powered by and Itech6K and 2 SRX715's powered by and Itech4K with 2 EX2.2's.

    We (band) greatly prefer the EX2.2's over the SRX718S's. The sound better, provide more punch and are a much more flexible option. Do a search you will find the review in this forum.

    BTW- for both setups you listed neither one needs a Driverack. And certainly not the KV2 setup. The SRX rig has the processing in the amp so the drive rack is redundant and the KV2's have the processing built in.

      Ned is spot on. The KV2 system will simply out perform the SRX system.

      If you're looking for an esoteric sound quality that is plug and play there are few more capable systems available.

          While KV2 certainly has a good reputation, the EX 2.2 won't "out perform" the SRX if extended low frequency is needed.

            Actually both JBL and Crown call for 1600 into each cone.

            For my 3 piece coverband, the EX2.2's definitely out perform my SRX, especially with the kick drum and bass.

              well the 2.5's go lower than the 2.2's. Any online dealers for KV2? i'm having a hard time finding any so I can't guesstimate prices.

              also, would that amp be a poor match for 2 srx728's? what would you recommend?

                In looking at the EX2.2 specs on KV2's website, I see two very different numbers for its response. Their webpage says, -3dB at 45hz but their PDF file says -3dB at 38hz. do any of you guy's know which is right? Seems like the first one is and the other is a misprint from the 2.5, but what do I know?

                  I'd go by the web site, the PDF is listed as preliminary.

                    I believe BillESC is one.

                      I would say that 1 SRX722 over 1 SRX728 should cover 300-400 people indoor with rock music. Also get your horns in the air, I would put the center of the horn up at 7' and add a set of front fills to cover the first few rows.

                      SRX728s does hit lower and hard than a KV2 EX2.2.

                        A dual 18" weighing in at 167 pounds that requires a very large amplifier ought to hit lower/louder than a self powered dual 12" that weighs a hundred pounds.

                        However the EX2.2 comes very very close in performance and I'd much rather move it around than the JBL. Space is also another consideration, the SRX728 takes up 19.25 cubic feet of space vs. the EX2.2's 6.36 cubic feet.

                            IME, I have seen a lot more damaged JBL product powered this way. Even they don't powere their own powered speakers this way... they power much closer to the RMS rating because they are more obligated to honor warranties on a self powered product.

                            IME, around 800-1000 watts per driver is just about the point of diminishing returns. Power compression begins eating up the SPL gains anyway, while the potential for damage gets much greater.

                              (I don't know how to do 2 quotes in one post)

                              I have a small bit on contention when I see someone who does sell KVaudio stuff do these types of comparisons as if to sell right here at the forum. Literally this isn't happening but the line between advice and sales pitch starts to blur. Sorry bill, just my observation. I am not in retail, however I remember those days and did a lot of selling 10 years ago. Back then what we sold were the best thing in it's class too, and our competitors didn't hold a candle to what we were doing.

                              So comparing a passive sub with no power to an active sub is basically impossible. Crown recommends one thing, crown dealers another, JBL another, QSC would like a say, so would everyone else too. And processing? Too many variables.

                              Let me phrase it like this. What gear I have right now is not a variable, it's what I got (different than what most people have). The OP has a certain setup as well and hopefully for everyone has correct power, processing, gain structure AND can mix.

                              All that being said, in my circumstance: I'd pick the SRX728s (again, I have 1 pair). Yes you have to put wheels on the back, yes put 4" rubber feet on the bottom (er side). Who takes these out of the box and takes them to the gig? It's not practicle, certain things have to be done to these to make them more person freindly (not a knock on this product but many speakers etc need a few tweeks before heading out to a gig, ergonomic usually).

                              sorry for the long post
