Why not horns?


I've owned a lot of speakers over the years but I have never experienced anything like the midrange reproduction from my horns. With a frequency response of 300 Hz. up to 14 Khz. from a single distortionless driver, it seems like a no-brainer that everyone would want this performance. Why don't you use horns?

DCM 50 is a mid-range driver designed to cross over at 9 Khz. DCX 50 is a coax. I don't use the tweeter.
Here's what you need to know. I like my speakers quite a lot and I don't care if they are flat, fat or phony. However, B&C is a very highly respected line of Italian drivers. I use them because Bill recommended them to me, not because I read the specs. RCF is also an Italian company, also highly regarded.

I included links to my drivers earlier. If you want answers, go back and read the thread. You seem like you want to challenge me. Why?

If you are really interested, do some research on your own. So far you have been too lazy to read this whole thread. As for your IMO and your presumed expertise -- save it for someone who needs advice. I have received sufficient guidance from Bill.


You make absolute absurd opinionated statements than get rude and antsy because you are questioned about such. LOL.....

I would suggest you record yourself and play it back a few hundred times instead of putting it on the internet where others might respond !

Four hundred hertz is probably more than two octaves below that woofer's upper rolloff frequency, so it will be plenty "fast" enough to do its job. The radiation pattern will be fairly wide at that frequency, and the cone will probably still be pistonic.

Weseixas: "...based on what you have expressed so far, it would be baffling to not have a high degree of nasality."

It is quite possible to build a horn system that doesn't have a "nasal" or "horn-like" signature. Part of the solution lies in the design of the horn itself, and part lies in the crossover. Having heard several Bill Woods designs over the years, I have every reason to believe what Macrojack says about his speakers.

Thanks, Duke.

Here's an ad for the woofer I'm using. It is now discontinued and I had to do a lot of chasing to find a pair. Notice the frequency response.

Here's the AH 300 horn:

and lastly, here's the mid range driver:

I am presently using a DBX Drive Rack PA for crossover, time delay, and EQ.
Reading comments on The Lansing Heritage Forum led me to purchase an XTA DP 224 speaker management system to replace the Drive Rack. Presently I am waiting for Dave Wall of Snob Productions to find time to bring his XTA software to my house for professional set up. We're tentatively scheduled for next Tuesday morning.
Fast woofers they pass me in the slow lane. How many MPH can a fast woofer do anyway? And why do people still think of bass as fast or slow. For to me this doesn't describe any real aspect of sound quality. I have never heard fast or slow bass and I design bass systems. I have heard time delay, limited transients, excessive distortions, phase issues. But not fast or slow. Since these drivers are not going anywhere I would say all transducers are very slow indeed. Unless rolled down a steep hill then a fast transducer is possible.
