I thought the co-ax 2" was the B&C, not the BMS???

Has to be the BMS since the diaphragm sizes dont line up with the b&c. Also, i remember seeing some pictures somewhere showing the BMS but i cant seem to find them..
Edit: Link confirming a user they contain the 4590. Edited by Teunos - 01 April 2017 at 6:32pm |

"Mayb I'm doing something wrong hahha"
How narrow is that slot? (quack, quack, frying-bacon-sounds, etc.) |

Tbh i don't really understand the physics behind theese boxes. They use some pretty entensive EQ to mess with phase and response like -15db at 1.4 khz with a Q of 5. Looking at available plots and data they are very liniar and they sound really really good in a subjective listening test. The 12" section runs out of steam before the horn. Some users use additional 2x12" boxes to et the full grunt out of the system.

Yeah had a feeling it would be the 12's , anyone know which 12" driver there loosely based on .. What wattage is the cab and what's there minus 10 db frequency on the low end ? I'm thinking they've probably gone for a bit of an inbetweener , not really a mid but not a sub !
That's the trouble with big horns , u probably need 4 12's to match efficiency but then there's a fairly large distance from the lower positioned 12 and the comps axis ! Could use four tens which would bring them closer together and just except that it isn't gonna go very low ! @ djk have you actually heard the m200 on the 2360 , I presume u have as I seem to remember you stating you once used to sell people the m200 to swap out there jbl comps ! Anyhow , the m200 is actually a much nicer compliment to the 2360 ! The m200's somewhat smooth relaxed sound balances out the big efficient dynamics of the 2360 horns and Iv allwAys thought that they need a really high q attenuation around 2.4 ish .. Seems to be coming from the horn !! I did consider the idea of inserting a ring of sound absorption on the inside of the slot from top to bottom at the point that the throats width correlates to the problem frequency but havnt got round to trying it yet ! Anyway sorry went a bit off topic there lol |

But nowadays we have FIR crossovers that can do extremely steep phase coherent crossover. Jumping from 12" to a big horn auddenly is not a problem anymore at that point since there is a near perfect seperarion of source material across the two sources. That way you will never get any kind of lobing in the vertical plane. Whether or not you want extremely steep crossovers when the two different sources are physically large and the source material is a whole different discussion, but in my two years of experience dealing with mainly FIR on my main pa, i would definitely pick extremely steep phase coherent without vertical lobing over shallow crossovers and overlap between sources. Just my 2p. |

Most of the M200 I sold ended up on the 2350 horn, which does not have the narrow slot.
It kind of depends on how loud you need it to play (before it quacks). |
