Lab Sub Vs EAW KF940
Todd Anisman:
The word is that the Lab beats a KF940... but I think the KF goes lower, yes? According to specs & whatnot... Who's heard both?
There are good deals on the Labs & KF's right now...
Silas Pradetto:
No chance is the KF940 going to beat a LAB. And no, it doesn't go lower.
KF940 is a bit less than 100dB at 30Hz, let's say 98dB. The LAB, IIRC, is about 103dB at 30Hz. That's a 5dB advantage for LAB sub.
I don't know where the KF940 unloads, but it certainly looks like crap on the graph. EAW only gets it's flat response from a heavily EQ'd preset. The LAB unloads at about 30Hz, and in sufficient quantity could be used into the mid-20s.
Todd Anisman:
Interesting... I know you own Labs... Have you heard the KF's in a comparative fashion? Both are heavy ass beasts...
would you say that 2 Labs per side would be enough Boom to cover 3-400 outdoors, at about 110dBa @ 75'?
I'm not great at the spec reading, and I find most of them to be somewhat misleading... so i ask these question from a real world & experience perspective..

Two LABs = about 3-4 double 18s, so would do the job. Four is way overkill; you could do at least 1000 outside with four.
And we don't use the A weighting to measure subs, we use C.
Two LABs should be able to do 118dB at 105 feet, given each sub gets 2000 watts.

Hey Silas,
The thing that might shift things a touch is that that KF940 graph is in whole space according to the title at the top.
But if I had the choice I would most probably for with LABs.
Take Care,
Phil
