Why not horns?

Macrojack I took at look at the spec sheet for the woofer in your speakers, and it's quite impressive. The response curve looks unusually good, and the parameters predict excellent bass power and extension in a suitable large cabinet (which is not always the case with 15" prosound woofers).

Also, sorry about the typo in my last post; "...which are onstant-directivity type" should read "...which are constant-directivity types".

Duke - Once again you have shown yourself to be gracious, considerate and knowledgeable. So, thank you again.

As I mentioned above, I am not technically inclined and therefore not technically proficient. Awareness of that fact leads me to choose an expert upon whom I feel I can depend. These people are carefully chosen and adopted gradually unless I can determine through research that they are what I hope them to be.

With Bill Woods, I felt no need to approach with caution. He is a well-respected and highly sought expert in the field of loudspeakers and one of the leaders in horn research. Tom Danley, according to Bill, is likely the king of that field today.

Horns are not so simple as many here seem to believe and the level of misunderstanding shown in this thread reveals and reinforces the need for further learning. Bill has worked at this for over 30 years and knows whereof he speaks. I urge all of you to visit his website and read every word he shares.

The Danley Tapped Horns, including the SPUD, demonstrate that new ground is being broken in horn design even now. The tossing around of conventional wisdom about horns and what they should look like reminds me of the yogurt, honey and sprouts era of nutritional wisdom. Lots of people still think that's what it entails.

As I said earlier in this thread, too many people are unable to differentiate between what they actually know and what they have chosen to believe. Most of us know almost nothing about horns as is evidenced by the negative comments some have seen fit to post. Of course, there are drawbacks to horn speakers such as size and cost but both of those issues have been addressed to some degree and, no doubt, will be further improved with time. Every approach has compromises and tradeoffs and not everything is a workable solution for everybody. However, the purpose of this thread is to overcome misinformation and share what we actually know. Whether or not my system represents the best options or I am an expert has no bearing on the topic as a whole.
Personally I think, from the experience I have had with my horns so far, that the upside here is tremendous and that DSP is probably the key. Passive crossovers are destined to join the typewriter and the abacus.

"Most of us know almost nothing about horns as is evidenced by the negative comments some have seen fit to post. "

LEts not sugar coat it. Most negative comments are based on actual personal experiences that should not be discounted in an unbiased discussion. There are many bad examples of horn implementation out there over the years as well as good. This alone indicates horns have potential, but are not a panacea. I believe that to be true and that people considering horns should be aware of both sides of the story.

MIcrojack, I can't fully include you as a horn guy if you don't use bass horns. :-) Hybrids are for cowards. :-)

Just kidding here. I almost gave up and went the box route for the bass. I'm not quite ready to do that yet. I may have to a some point if the vintage pro drivers I use become any harder to find in good condition.

I am also in disagreement with the use of digital filtering. I understand the issues that digital processing can address, but it simply doesn't sound better to me. Different, yes. I would rather live with a little shout or whatever, than lose information. Matter of fact, I would rather go back to using passive speaker level xovers than use DSP.

Bill has indeed revived the conical horn. From what little I know on this subject, the conical was studied a bit back in 50's or 60's but then most turned to other approaches. The claims regarding the lack of phase distortion with conicals is interesting. Thus my desire to model that at some point. But for those who think building a conical is easy, think again. Those 16 or so slats have to identical or there will be un-eveness, which defeats the reason that the conical does what it does.

I would say, however, that tractrix is still the more preferred approach at this point.

I think the advice I was given by Ralph when I asked him if he prefers a horn system or electrostatic speaker when using his electronics and all else being equal fits 100% into this thread and his response was "it really depends on the speaker rather than the technology. Its the 'all else being equal' part that prevents an answer beyond that. Either one can be awesome or suck really bad." I some day do wish to explore a horn system and this thread has given me some of the understanding needed to do so.
