A safe general rule of thumb for an unknown driver is to keep it below 3:1 with what you consider a stout driver, and around 2-2.5:1 for a regular driver. navigate here

I'd like the CD to get down around 1k, a little lower would be nice. http://www.diyaudio.com/forums/attac...amp=1208804423 Let's see how many more compression driver parameters can be found. Peaks are a little bit shorter with a throat chamber. Tapped horn design is tricky, but McBean gave us a wizard that helps visualize things while designing.

To be safe one usually considers the beginning of the horn to be past where the cone exposure lies, except in a tapped horn. Again, it would be great to know which parameters could use actual values. | AkAbak script - DE250 Compression driver | Parameters preceeded by ...... good god, you would only need 5 watts to run those, lol. 08-11-2011 #5 thehatedguy Diyma Ninja Join Date: May 2007 Location: Nowhere, overthere Posts: 11,261 Thanks: 4 Kind regards, David Thank you David.

At what cost? (because nothing is ever free.....) Well, the box is 149 L larger, the fold is more difficult, and the simulation takes more time.
I typically use the area of the driver cutout and several thicknesses of material to allow for cone excursion, unless a large chamber is called for, where I just make a check over here Hoerninger06-16-2010, 08:40 AMThe directivity of a horn is dependant on the layout(circular, square, bi-radial...). Seems like more uniform dispersion would be the right way to go with the subsequent adjustment to the X-O to address the sensitivity change. They were upside-down drivers with metal cones.
But you get the point. You can measure the actual resistance if you have an accurate meter. The actual figures used by P.Audio in their Hornresp simulations were: Sd = 34.00 sq cm Bl = 8.00 tesla.m Cms = 6.20E-05 m/newton Rms = 0.74 newton.sec/m Mmd = 2.77 http://fallbrookpcusersgroup.org/compression-driver/compression-driver-wharfedale.html Review: Behringer Ultracurve DEQ2496 EQ processor Sub amp options Are sealed subs faster than vented?
Sure they get larger as they taper but that's at a fixed rate determined by the type of horn and flare rate equations. soho54 put together some great graphics, here's what we're talking about: So - does the CinemaHorn have a throat chamber, is it an offset driver horn, or is it a hybrid? If you want to get low take a look at the DE950TN or DE1050, they seem like interesting drivers.
I find that very small throat areas work well for good top end response in midrange horns, but I don't go too small in bass horns due to cone pressures. I admit that I have difficulties to like people who design horns in Hornresp but… for whatever it worth… It is not that I hate the software itself bit I hate If you make it to small overall efficiency will go down, and low frequency response will taper off, and get very ripply. The front and back chambers?

Hi JLH, The only input parameter values I have are for the 120 watt PA-D120N compression driver. Having all the information in one place should help.
