Powersoft 30 inch sub seen in the wild!!
This one is not commercially available yet, AFAIK, but may ultimately prove to be the future of high powered subs.

I've played with the models for the 21's. They still require a large box to be at their best - larger than one required for the 18's. They're still subject to the same size/wattage/frequency tradeoffs as anything else. And I don't see any provision for LN2 cooling yet.
othorn is a contender imo. SMALL box for the solid 29hz it puts out (8cubic feet smaller than a labhorn!). massive powerhandling...
the Gjallerhorn would be the king if it played nice above 50hz, alas, tapped horns have their flaws.

You can use the gjallerhorn above 50hz....? Josh's measured results show that it's more than adequate.
It exhibits a 10 db peak at 63 hz, and a 10 db peak at 95hz. as power is applied, you can see the area between 70 and 80 starts to droop even more (resulting in almost a 13 db difference between 78 and 95 (minus the peak at 73). The peaks and droops are actually worse than the ones in the sim (below 100hz). Ricci also notes that distortion gets a bit out of hand above 63hz.
There's a reason why people are using gjallerhorns AND othorns in the same room.

Es-15bhl ?
Tengo 6 T48 DE 24" Con eminence kapa lite 3015lf y no estoy contento, solo que tengo mis dudas al construir el modelo de Staiper Es-15bhl "MICRO-HOG" o el SS15, jBELL tiene usted alguna sugerencia al respecto ?.

Is it possible to use jbell ss15 loaded with 3012LF small weddings with a smallish 8" Beta A woofer and use a passive crossover for the lows? Tops will be passive crossover for smallish DJ wedding venues less than 100 people indoors and where can I find the latest ss15 plans? Was thinking the Fusion 8 diy sound group? Thanks!
1. The SS15 was designed around a larger driver. I wouldn't suggest using it for the 3012LF. Look around for one specifically designed for that driver, or just design your own, based around one of the existing designs for 12" drivers. Using HornResp and the appropriate spreadsheet from the "Spreadsheet for Folded Horn Layouts" thread, you should be able to come up with something pretty easy that fits your requirements.
2. I don't recommend the use of passive filtering like you suggested. Active filtering (DSP) is the way to go, as you'll need to use EQ, delay and x-over features to get the best results. The lucky thing is that you can get all of that and amplification too for at pretty cheap price if you opt for one of the Behringer iNuke amps to drive your system.
3. My small PA system uses Beta 8A drivers for the tops and at 12" TH for the sub. I've used it for background music and it works quite well. For an indoors wedding reception with 100+ people that are likely to get a bit "loud"? I'd probably opt for something a bit larger 🙂.
