Hi everyone,
I am building a 12V P.A System for 100 people outdoor parties. I'm aiming to build two THAM 15" for the subs. I have just analysed three Drivers on Hornresp for the THAM 15", but it's my first time using Hornresp so in do not guarantee the exactitude of the results (see images below), i still hope it can help anyone in the same situation ! But i might need your help to decide. The three speakers that i have selected are the BEYMA 15MC700 Fs41.00Hz Re5,9Ω Qms4,8 Qes0,38 Qts0,35 Vas153L Cms140.0μm/N Rms5,7kg/s η02,7% Sd0,088m2. Xmax9,8mm Vd880cm3 Le1mH Precision Devices PD.156 Fs50.25Hz Re5.69Ω Qms7.45 Qes0.5 Qts0.47 Vas93.4L Cms80.83μm/N η03.63% Sd907.92 cm2 Xmax8.1mm Vd0.648L Le1mH FaitalPRO 15HP1010 Fs40.00Hz Re5,3Ω Qms10 Qes0,38 Qts0,37 Vas93L Cms140μm/N Rms5,7kg/s η02% Sd759cm² . Xmax9,8mm Le1.8mH Each Sub will be individually powered with Pioneer GM-D9701 class D amp (500W RMS at 4Ohm, so i guess 250W RMS since speakers are 8Ohm). I know that for Tapped Horn i should head to large Xmax. I also know i should seek for efficient driver, that have good sensitivity. I also don't want a driver that would cost more than ~200€ That being said, i'm still struggling to make my decision (its my first time buying a speaker) Do you have any advice on which one to pick (or on any other appropriate speaker for this purpouse) I am also open to other sub plan if you have any suggestions ! thanks in advance, Lola |

well from your sims the faital looks best and has good xmax, at the power your going to use you shouldn't be getting near xmax anyway. Greg

All right, but they are the least efficient (2%) and least sensible (96dB),
the two other one are rated 3% efficient and 98dB sensitive (BEYMA) and 3.63 % efficient and 97dB sensitive (PRECISION DEVICES) So in a 12V rigs i must say i don't know wich parameters to take in account the most, i'm still pretty newbie in these terms ! Thanks for the advice anyhow Greg ! |

They will all be very similar efficiency under 100hz. Efficiency is not usually measured down that low
