it has less SPL than BPH. It sounds flater , goes deeper but doesn't have that bump on Kick zone , like BPH. Overall, i am more satisfied with this cab instead of BPH. My near future plan is to build another SB15 , loaded with the same SD15 driver. Than i will eclipse an BPH, in every aspects. This 2 cabs will be more portable( beeing 2 subs instead of 1 ) and it will have a lower cutoff. Sounds more linear.

RCF L15P200AK is only 13.5cm high, and so are enough others. rcf l15s801, lf15g401 is 15.8 as well as L15P400 and MB15H401. And those are only RCF. Btw, the RCF MB15H401 sims very good with this design Edited by Teunos - 28 August 2009 at 3:58pm |

One Member mentionend the ARLS (Advanced Reflex Loaded System) in the first Thread.
If you like a clean and very well performing Reflex Sub, that matches easy with nearly all kind of Tops from 38 - 150Hz and a very handy shape, then this Version 2 of the ARLS could be interesting. https://aw-audio.de/boxenbauplaene/PS-Bass%20MK2_.pdf Edited by aw-audio84 - 22 September 2020 at 11:09am |

Now that is interesting -about 5 years ago, I designed and made a set of 15" bass bins that ended up being almost exactly like that plan. I had internal volume of 87 litres and a tuning frequency of 55Hz not 42Hz, but otherwise the layout was nearly identical, with a big shelf port at the bottom and minimum-width baffle. With Fane Colossus 15XB's in them, they performed extremely well. Undistorted deep bass to 40Hz and good cone control. A pair in a corner, seemed at least equal to a 2x18 bin (although no comparative testing was done).
Perhaps it is one of those magic formulas that works with lots of different 15" drivers! It's a convenient size for putting in small vans or cars too.
