I did end up making some Keystone subs. I have two built so far, and two more cut up and ready to assemble. I don't have a lot to compare them to, but when I cranked em up in the shop last weekend, they made lots of noise...  :)

Thanks for the recommendation.


You are welcome!
I think you will find as well as making a lot of noise, they sound quite good if you delay the tops to align with them at the crossover frequency.

Have fun as part of the growing Keystone Kommunity!

2 x Lab subs a side does not work that well, you need 3 or more before the horn mouth is big enough. 4 per side would work well.

For general purpose applications a good double 18 with some of the latest drivers and a big amp is hard to beat, its also relatively easy to build and will work without any DSP correction.

For 2 x 850s a side you will need at least 2 good double 18s a side, 3 would be a better match for most applications.

You also need to consider that the 850 is 26.4 wide at the front and 29.5 deep. Whatever you select will need to be big enough to stack the 850s on safely.

DIY cost effective solution -

Better (joint two of these together) -

or these look great but need a bit more bracing.

Edit - I would also suggest using the UX8800 as your crossover.

Interesting, that b&c BR design must be rather new on their site for the 18sw 115?

I thought that driver were less optimal for BR designs but the simulated graph looks rather impressive for ~200 liter net. I wonder how it compares to a box with similar size with either bms 18s450 or eighteen sound 18nlw9000 and low 30's extension which are more BR oriented drivers.

I am not working for P.A.P. I am the proud father of Paul Pierce who is the founder/owner/operator of said company since 05.

Papa was a rolling troll, wherever he laid his hat was his home.

I know this post is old but if you are going to troll at least make sure you have the right audience.

The professional sales trollers on LinkedIn make me insane.
