"Equalised plot". Does that mean averaged by software, or you flattened manually? |

I haven't PD1850 but you can put TS parameters to my MG218v2 hornresp model and try... V3 has ~2.7 compression ratio (same as in WSX).. so drivers must have same parameters...

I see that single MG218 v2 has too small mouth area for double 18" to be excellent choice for outdoors standing... It must be 2 cabs per side
But indoors it would be very powerful decision!

I guess compression ration is Sd/S1 ? Any numerical equations to match qts/Vas to compression ratio? Edited by levyte357 - 20 September 2009 at 1:49am |

Ok i know that this is slightly off topic but since its allready been brought up in this thread i find its as good a place as any to ask. As per phantom horn length is concerned i absolutely see how the physics of that work when the horn is standing up. however its my position that if you were to say lay that bin on its side or put it up on bricks you loose that additional length of horn. ok so am i pretty close here or am i totaly off point?
