one of our DIY midtops. inspired by line array concept. the line array guide published in P Audio website although not about butterfly design, is also helpful.
advantage- has wide coverage & directional, disadvantage-it became totally too bulky and sometimes hard to hit the right balance of the sound between the compression driver and the C12". we hope to have one speaker management audio processor soon. (any recommended brand aside from Driverack PA?)
drivers 1 pc BMD 750, and 2x C12" 300W (but then we run out of budget, so we inserted non P Audio drivers.

Thanks for sharing.
It seems that the Sd18 has a "wider" operating bandwith than the Pd1850. . .
Crown Amps
Which of these Crown amps can Drive 4 pcsof JH181 or jh186 ?
Cs1000
CA850
Crown - The Professional Choice
Thank you very much.

@zrolsky...if i have the money these are the choices.
Dn9848e from Klark Teknik...no.1 choice
DP428 from XTA...no.2 choice
Driverack from DBX...no.3 choice
DCX2496 from Behringer...this is ok, not so pricey, lots of tools including long delays for delayed speaker reinforcement. I dont know if they are as durable vs. the 3 giants. So far 3 of my house of worship installs got these dcx2496 for delays...3 years only one break down PS failure...maybe because of the genset.
Kudos zrolsky for modest and honest sharing...keep it up.
have a nice day

both of them will do...both can handle 2ohms loading...sub woofers are lo freq. radiators thus the lower the freq. the lower the impedance will go. Its good know that crown have a site that post their data...thanks for the link.
But you'll be better-off with the CS1000...got more juice and high damping factor.
thanks for the link again...helps me a lot since i am using a lot of crown products.

BTW, do we have what you call "local produce". sorry, honestly i do not know. how about Crown speakers. I often hear its "local" but who really manufactures these speakers, and pls, perhaps the owner is?
Thanks for sharing.

not only wider, but also "flatter". i mean it is consistent in every frequency. perhaps due to its power, a real 1000W.
void 18 1000 (black) vs PD 1850 (gray). note that the V1000's BL is 34.89 and vs PD1850's 31.57. Void is 1000w and PD is 800W.
but these are only "approximations". we have to take into consideration power compression and excursion (xmax). maybe it is safe to say "the bigger the driver, the better." or the other way around is, tailor the box to fit the driver's parameters.

thanks a lot. it is a good feeling to receive a compliment from masters like you. i also go for DCX ultradrive. btw, the pict that i have shown about the butterfly mids is the 15" version. we made 2 x 12s and 2 x15s.
thanks for sharing the simulation dude.
Awesome! to me the guys at PD really know what they are doing. Looking at the simulation, the pds 1850 shows a peak on the 100Hz region and a dip on the 60-70hz and a peak again near the 40Hz. I believe this done to let the "punch" get through since 60-70Hz are the "hum and booming" frequencies, that gives the bass a muddied quality. The near 40Hz gives as that "phat" low end. however this is just my two cents
and the simulation also shows that the pd has a well damped motor cheers
