I have 2 of the XLF's with 2 PRX615m's and love them! I want to get 2 more XLF's and 2 PRX625's or 635's for large rooms. You mentioned in the video that 4 XLF's and 2 625's would sound fantastic. What I was thinking is using that set up, and putting my 615's on the far sides. Would that be too much top end for 4 XLF's and drown out the bass? Also, for that set up, do you guys recommend the 625 or 635?

@noodlecake71240 We think that would be a great setup. We'd lean towards the 625 for you vs the 635.

Because the JBL PRX618S-XLF is so tall, can you lay it on it's side to make it fit under a table without distorting the sound? Great video.

[agiprodj]

@missle25 Definitely worth a try!

I'm torn between the QSC KW series and JBL PRX series. I love them both, but I heard multiple reports of the PRX's over-heating and shutting down. Is that really a common problem with these? Any chance that this problem will be fixed? Is there anything I can do to keep the subs cooler like maybe a small fan blowing on the amp in the back? If that would even make a difference, I don't know

@noodlecake71240 We've asked JBL that question as well. The overheating reports are accurate, but not to the extent the forums would have you believe. There have been isolated PRX600 series speakers that have overheated, shut down, etc. One nice thing about JBL is they'll take care of you if something like this happens. QSC's by comparison are fan cooled, which could of course also fail at any given time. Either are great choices. Feel free to reach us directly for more information. Thanks!

Very well said at the end of the video, I made that mistake of buying for less when i should have waited to get the best'

I'm getting 2 KW181 next week for my K12s. The Ksubs are not enough to handle the power of the K12s in an open area. I will test the two KW181 with my DAS Avant 215a while waiting for the 4 DAS Avant 118a that will be in by end of January yet.

@agiprodj I'd like to bounce off of this thread a little bit. The 635 is a 3-way, so it's supposedly better at reproducing the full spectrum better than the 2-way 615. However, when you look at their frequency sweeps, the 615 is flatter than the 635. Why is that?

[Martmank]

Thansk Guys, beneficial info!

[Kcducttaper1]

You gentlemen do a wonderful job of explaining the techy bits of comparing speakers, but it would be nice to hear them as well. Perhaps just rig them up in stereo and pan left (JBL) and right (QSC) so we could hear the tonal differences. Granted our computer speakers or headphones will make a difference as well, but it would give us an idea of how they compare as far as tone goes.

[noodlecake71240]

@agiprodj Ok awesome, thanks! You think 4 XLF's would be enough with 2 625's and 2 615's? One of the larger room I remember is about 70 buy 95 with high ceilings, about 18 feet or so
