Post Subject: WAF and you've been warnedPosted by serenechaos on: 10/20/2008

Robert, what I meant is following: when you will be collecting requirements for you own drivers specification and will evaluate the implementation methods then you need to have you own identity what you are trying to do. I might post a lot of different thoughts about what might work interestingly in compression drivers. I am sure others would do the same but it will be not definitive direction but rather an array for exploration. No one can defiantly and predictable say hop the driver will sound and in particularly no one can say how it will be sound loaded into a horn. So, when you hear people talk about requirement to the drivers you need to have a lot of YOUR attitude to discriminate information and to accept only what makes send to you.
Ahh yes. This is the heart of the matter isn't it?
It is impossible to know (objectively) how a driver is really going to sound until it is in the system, and even then how an individual (subjectively) will recieve it, and if it will "solve an existing problem."
I'm just looking for any good information on how really good drivers are built; and where to look for if there are problems. As you have evaluated quite a few drivers I thought you (or someone else) might have some suggestions. I ask everyone I talk to, read everything I can. File what makes sense, discard what doesn't.
If I were in your shoe I would take make as you wish but wish a slight correction:

This is a possibility. Originally I was thinking along those lines, just to simplify things at first, but I had a 600Hz crossover point in mind. But the lower crossover point integrates better with the mid-bass. (My mid-bass will be deeper than yours, and won't have as long a tail and go as high).
Yes, the mid-bass horn is a pain. Bulky and awkward but what else will work as well in that range? Nothing.
John, Jeffery, and Josh had all recommended the Radians as good baseline drivers to start with, so I'm trying them. I may pick up some 375/2440/2441s to compare.

Wife Acceptance Factor-- John Hasquin tried to warn me about this too. Jeffery understands, he was there.
When we were @ VSAC, my wife and I sat down in the room Jeffery's system was playing in.
After about a minute and a half, she quietly turned to me and said "you can build one of those, right?" with this hopeful look in her eyes. To her WAF is about what it Sounds like, not what it looks like, or how much room it takes up. She thinks it funny that some people seem to "hear with their eyes."
I've had the 80Hz horns mocked up on the floor for a couple months, and been experimenting with the midrange drivers in various cludged together horns. The only complaints are about the Sound, when it gets worse, and comments when it is better. Sometimes she can hear what seem like minor changes from the other end of the house...
