Compression Driver Hornresp
However CD horns do not have a flat freq respsonse and will require some EQing to boost the high end. I used the CinemaHorn for consistency. This is just so people won't be so afraid of hornresp, and it descibes how I go about screwing around with OD horns.... Since we just entered Sd, it is right (unless you type like I do...), click Yes. http://vocollectapp.com/compression-driver/compression-driver.html
You would want a pretty substantial tweeter though...not just any will do. Work out the folds in CAD, then build it and measure it nearfield in the mouth, see what you learn. Please add to the list if you find one that behaves well.... Hornresp is in a way familiar with front and back chambers, multi-driver chambers and different horn profiles.
they are just over a milimeter or so of each other.....So I consider it a decently fair comparison, hypothetical though it may be.....and, for the record, I didn't optimize the sealed Sorry for the long post, looking forward to hearing your opinions and experiences with these drivers and any others you can recommend Cheers Tim The main reason that you'd use a The folding tutorial will be a royal bitch to put together (may have to do a video or something, individual images wouldn't be as instructive), so it'll be a little while Change L34 to 500, and increase the driver chamber (Vrc) to 70....now you have a 20Hz horn.

If so then you know the answersâ€¦ Also, what impedance would say to you without the relevancy to the actual sound?
kevinkr06-15-2010, 09:40 AMA little OT: I'd be very interested in hearing more about the directional characteristics of conicals vs tractrix if you have any insights you'd like to share.

The dispersion pattern of this driver seems to result in great uniformity in my room, however it can also sound a bit congested at times, and it is definitely the horn AVSForum.com is not sponsored by or in any way affiliated with AV Science Inc. I find most of the information in bits and peaces. Your specs should look like this: Press Calculate, let's see if this works. (Quatro in black, original is gray) Hey....not too bad.
The Offset Driver horn option was added to Hornresp as of Version 19.00 (April of '08). With a horn, you get more ragged response, a larger box, but more output in a passband with less power. 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 Matching data generated using the strategy suggested by Earl would be better but I haven’t yet commissioned my test gear.
The midrange horn needs to run from 800Hz - 8kHz which is a pretty tall order I guess for a 2" driver at least on a conical due to the falling his comment is here In sum, a "conical horn" may deviate at the throat and mouth by design. The larger the horn the lower the cut-off or loading. Diffuser panels: why you need them and how to make your own An acoustic diffuser is generally more difficult to design and build, hence more expensive.
Sorry for the long post, looking forward to hearing your opinions and experiences with these drivers and any others you can recommend Cheers Tim Remove Advertisements Sponsored Links DIYMobileAudio.com Advertisement For the graphically challenged, the illustrations in this thread are priceless.

Soho, Thanks so much for the drawings. We play with ONLY 4 THINGS: Throat chamber size, Mouth Area, Length, and Rear Chamber size. ulf wrote: If you have no experience of HornResp I suggest that you download a copy and try it out.

I have decided not to build any horns at this time as I realize I do not have the requisite knowledge nor the time at the moment to do it right. Cms is next. I decided to take a look and see if it matters. I noted the tonal balance in my system is a little better (tolerable?) slightly off axis than on - which may mean that the conical might actually be a good choice??
As they get bigger you need to go down in compression, and with smaller drivers you can get away with higher compression. And in a car it is really hard to get into the far field of anything except upper midrange and treble. 08-11-2011 #10 Eric Stevens DIYMA Enthusiast Join ReplyDeleteanomalousApril 17, 2013 at 7:21 PMworking out the folds in CAD is where I am at the moment - my current method involves drawing a centreline down the middle of the http://vocollectapp.com/compression-driver/compression-drivers-uk.html Logged EngineerISP Technologies Print Pages:  Go Up « previous next » ProSoundWeb Community > Sound Reinforcement - Forums for Live Sound Professionals - Your Displayed Name Must Be Your Real
Trying to adjust 19 interactive parameters is akin to juggling jellyfish! But what he says about a big room to enjoy it all is a hint...you really should be at least 1 wave length away from the horn's lowest frequency when using Review: Behringer A500 power amp Update (March 2013): I posted previously that this amp had failed. The Smith seems to be some several dB less efficient than the exponential on the 2440, but has a more balanced sound overall.
