Default Nightclub speaker

I am thinking about building my own speakers, these would be high power and used in a nightclub. I was thinking about using two B&C 15NW76 drivers for the lows, two B&C 10NW64 drivers for the mids, and a B&C DE250 mounted to a QSC 152i wave guide for the highs. I am figuring on porting the 15's and the 10's would be sealed. The layout of the drivers would be similar to this Speakerplans.com


My questions are as follows:

Would this combination of drivers work well together?
What would the box volume have to be for the lows?
Port dimensions for the lows?
Box volume for the mids?
What would be the calculated continuous SPL?

I know some of you guys have the fancy software that will tell you all this stuff based on the parameters of the drivers, unfortunately I don't have any software so your help would be much appreciated.

If anybody has better suggestions, please share. I want something with a lot of output and above average sound quality as far as PA goes.

Thanks, Shaun

(I didn't look at your system). Do you have the xover (main brain) for your system? Have any idea, or developing from scratch.

You should have better drivers (not that it can't work, only more complex if possible because of B&C 10NW64) for the 2K region unless the "DE250 mounted to a QSC 152i wave guide" covers it with good integration. You should have tested setup or it will take you a long time. Look, for what to expect.

Nobody's going to come up with an optimum design without interest in building these themselves, as there is considerable time, effort, and expertise involved in modeling them.

I suggest you build a known entity suited to your application....

I second that when you want to use it professional and not have all the tools to optimize your design.

Here a nice link to 18 sound Eighteen Sound - professional loudspeakers

Hello.

I know the B&C 15NW76, good driver, well designed neoymium motor, well build... but it can't go low, only high spl, notice that real Xmax is only +/-4mm.

18sound are good drivers too, if you go with their kit, go for the neodymium, it's really lighter and roadies will appreciate.


EDIT : to go in the way of Elmuth, ARTA is a really powerful software with a well wrote tutorial.

To your qeustion of high output and high qaulity I suggest a line array.

Make a good sub with two 102dB drivers and you shout get 105dB and use a series of 6" or 8" drivers vertical above each other this will increase the sensitivity and good of axes behaivour. And use a line array horn driver.
like this http://profesional.beyma.com/ingles/pdf/WL3.pdf

Read this paper.

Thanks for the replies. Are there any other designs out there for high power speakers?

This idea always crosses my mind (to make things worse).
JBL 4350B

EconoWave Deluxe with subs, DE250 & 152i waveguide, 90 x 50 directivity.

EconoWave HP is on the drawing board and should be posted in ~60 days. It'll be rated for 600W, 95 db sensitivity, 123 dB max continuous SPL, 129 dB peak.

+/- 3 dB 42 Hz - 18 kHz, it'll probably want LF augmentation, also....
