Building Subs
« on: February 03, 2010, 12:18:56 pm »

I currently have an opurtunity to have some sub enclosures built. I have some trees that I am trading for these services. I was thinking of getting him to build me (4) Lab Subs. Are there any other sub enclosures out there that will do what the Lab Subs will?

He has a 65,000 square foot shop that he builds speakers boxes, that he sells nationwide. They are enclosures for cars, trucks, boats, and all terrain vehicles. He also builds what is called Extreme Houses, and uses trees for this.

Would (4) Lab Subs walk all over my (4) LS808's?

If there are any other boxes to build please let me know.

Thanks,
Rusty Irby

Yes.

And, at 4x the size too. FWIW

Four will walk over 16 of your LS808s...

Actually, only about double the space- four LS808 (without wheels) take up 46.84 cubic feet, four Lab subs take up 105 cubic feet.

The 45 inch depth is a no go for me, and if you are going two or more high, the width could be a problem in small venues too.


I'll repeat something I wrote about before, even though I know 650Ps are not that loud:

Got to do a side by side gig with my system ground stacked onext to a flown Vertec 4889 system, 8 per side with 4 Meyers 650P subs per side.
16) 18” cones, 9920 watts ”burst capability”,140 cubic feet of truck space, 1768 LBS.

Headliner frequently pushed the  650P subs into TPL (TruPower limiting) and Excursion limit. The spectrum was 60 HZ boom boom, about 6 dB more 60 than 40 HZ, which corresponds with the cabinet’s continuous rating and spectrum.
At FOH, about 125 ft out, the system was hitting 108 dBC, the hard limit, no extra VU swing resulted in any more output, though it did sound crunchier..

My stage was doing dance groups with recorded music and one live act. On the last dance group, with some fairly heavy LF  content, my 4) 2xLab 12” front loaded subs were hitting 104 dB, spectrum looking pretty equal from 40-80 HZ.
8)12” cones, 3600 watts, 31 cubic feet of truck space, 400 LBS.

+2 dB at 40 HZ, -4 dB at 60 HZ compared to the sixteen 18".

Not bad for something smaller than what Rusty currently uses.
And unlike a LS808, they sound really accurate.

How much do the Meyer 650P's cost, compared to the 808's?

Pete,

MSRP on the LS808 is around $1200, 650P would probably be about three times that. Meyers does not post prices, that's just a guess on my part.


Why do you ask?

I wasn't sure why the sound comparison to a sub that lists at $6260.00 a box.

The OP could get rid of the crap neo 18's they put in the current 808's since 2005, and put original ceramic magnet B&C 18 063 drivers in the box.
From personal experience...it is night and day.
The neo's sound boomy as hell, no definition, honky, hollow...and lack any tight punch.
Just like everyone says.
The ceramics sound WAY tighter, pound hard, and generally sound like a different animal altogether.
They are available, and B&C, Yorkville, and US Speaker, all concur with that. The ceramic 18 063 is a 1200 watt driver, and the parameters fit the box really well.
For $250 a box, it would be a viable option to try, anyway...
unless the OP has $25-50K to spend.

So why dont you just build 12 double 18s with good drivers and get on with it.
The other option will be to find 12 used JBL SRX728. They will give those 650 a run for the money Smile

Pete,

If you read my post again, I got a chance to compare four  of my small ported cabinets using Lab 12 speakers to eight Meyers 650P. My cabinets produced about 4 dB less at 60 HZ, but 2 dB more at 40 HZ than the 650P, using a small fraction of the power. In fact, my whole PA was running off two twenty amp circuits.

I did not compare the 650P to the cabinets the OP is currently dissatisfied with.
Changing cones in the LS808 certainly may help, but it does not change the cabinet design, different animal in the same cage.

For the price of eight Lab 12 cones (about $1250), he can get more LF output than eight 650P cabinets, in a package that is smaller than he currently has.

This is the response curve of my 2x12" cabinet:

How much and what type of power are you driving those subs with Art?  And how big are the cabinets?

I might consider building one if it fits the bill.
