Hi Sam!Thanks for the compliment! I appreciate your civil ways!
Hey, you asked for suggestions, and I will give it a try. OK? Remember, I'm more into acoustics, than into speaker designing. So DO take that into consideration.
Here we go...
Like you, I think that TAD High-Frequency Compression-Drivers are very expensive. However, there are cheaper compression drivers out there by Altec, JBL, and Radian that DO work very well in 2-Way systems. According to Tom Brennan, who has his own horn webpage, the Radian 475 sounds great, and it is relatively cheap (when compared to TAD). However, vintage Altec and JBL seem to be the way to go, esp if you get a good price over at Ebay! So do check Ebay frequently. Take notes of the prices paid. According, to Tom Brennan, prices DO NOT follow a set pattern. That is, the price of a specific driver goes up and down on different auctions. So you might be able to get a low price on an Altec 802-8D (used with Altec's 511B Horn) on a lucky day!Now, Altec's model numbers use "a dash followed by an 8" for 8 Ohm drivers, while the 16 Ohm versions do not! So watch out! Here's what it looks like...
Altec 604-8E = 8 Ohms version
Altec 604-E = 16 Ohm versionTake a look at Yuichi Arai's wood-horns linked below. He uses both TAD and JBL compression horns interchangeably. For example, his A-290 Karin Wood-Horn uses both the TAD TD-4001 and the JBL 2441J. And his A-480 Karin Wood-Horn uses the TAD TD-2001 or the JBL 2425J. Obviously, the vintage JBLs are much cheaper than the TADs. So that's certainly an option.
Keep in mind, though, that JBLs that end in "J" are 16 Ohms, while JBLs that end in "H" are 16 Ohms. This important because it's easy to get the two mixed up. Here's what it looks like...
JBL 2425H = 8 Ohm version
JBL 2425J = 16 Ohm versionAcoustically speaking, Yuichi Arai is right in preferring wood-horns over metal-horns (like the Altec 511B). Why? Well, metal-horns tend to "ring," and they impart the HFs notes with a metallic tone. Wood horns DO NOT do this at all! As a matter of fact, if you were to hit a wood-horn with a bat, you get a "thud," not a "ring." Thus, wood "tames" a horn better than anything else. They really sound great! Of course, they are also very hard to build! In this respect, check out Yuichi's "Process Section." It shows you how to build one of those horns.
I feel that Yuichi's site is a very interesting horn site! In my humble opinion his wood-horns are simply beautiful! I'm especially fond of his A-290 wood-hurn on top of his E-179 enclosure!
On Sierra Horns...
Go over to the "HF Speaker Asylum" and check out Bastus's posts. They are in the middle of a TAD driver discussion. He has a wood-horn (Le Grande) that has a 140Hz cut-off! Simply amazing! Then his 26" horn cuts-off at 180Hz. Can you imagine that? You can go from these low frequencies all the way up to 20,000Hz. Wow! Maybe this is precisely what you mean by an "almost full-range" driver. So please check it out! Then come back with your opinions on these wood-horns. I'd like to read what you have to say. OK?Good luck with all this. I hope it helps!
My best regards to you and your family!!!
