PL6.0's are a very good starting point - I use the PL380 on my labs (driving 2 cabinets a side) and i have plenty of breathing room running the rig hard. A very important thing I don't see anyone else mentioning here. To get the maximum LF response out of LABS you need to group them together in large numbers. The magic number being 6.  So a build of 12 Lab subs (2 blocks of 6 on each side) would probably be your best bet. If you decide to center cluster them.. which is a good way to go.. well you start putting 8 labs together you really need to arc them, or use some sort of delay (read horizontal bass  array) I don't think you need that many at all. I've done a 2500 person show with NAS in a large gym with 8 LABs and it was 120dB C at FOH 75 feet back with 10dB left on the rig. I'd confidently say 8 LABs can do 5000 people.

Silas,
If you brought 8 LABs to a 5,000 cap show of mine, I'd either ask you to:

1. Bring in at least 4 more.
2. Call your local recone shop now.

I did a show last year with 4 LABs a side for 2,000 people. I was into limit with the kick drum, and the 808 was bottoming them out. The LAB subs are great and all, but they, like any other sub, have their limits.

jeffhtg (Jeff Kenney) wrote on Wed, 13 January 2010 08:09 Silas.. I've been using 8 Labs (center cluster) in an indoor 1200 person venue for 5 + years now.. 1/2 of the nights are dirty south/freestyle/hiphop.. It is good for the room - but not overkill for these types of shows. (PL380 power). 9 times out of 10 when people say hip hop they mean Rap / Dirty South.. which is pretty much the crappiest music you could ever play on a P.A. system - and its usually played at "10". I wonder then if your LABs are built right, processed right, or if some room mode is messing with the bass. I can assure you, 8 LABs for 1200 people for any type of music is completely and totally overkill.

I would agree with Jeff, for this type of music 8 is about right for 1200 people, any less and they will be over driven. It is overkill, but that is what the kids want, the feeling, and when it's clean like the Lab, it needs to be even louder. They are not happy until they are shell shocked and confused from excessive spl.

Evan,

can you make a short comparison between labs and your b2's?
