Thanks Guys.
Danny, I am not a speaker designer like you, Rick, Fred and Jim Griffin.
But I always THOUGHT it took 2 drivers to make up a crossover slope ?
If the VMPS Neo Driver only goes down to 400 to 800 hz, HTF does VMPS cross it so low ?
The ORIGINAL VMPS RM 40 crossed at 166 hz.
It ADVERTISED Ribbon from 166 HZ UP.
Now, it crosses at 288 hz.
But you crossovers guys, please help me out ?
HTF can you cross over to a driver with almost NO output at 288 hz ?
This would SEEM to me that the 10 inch woofer is playing the mid range, right ?
Danny, you said you have experience with this driver, but HOW could you ?
I thought VMPS had an exclusive on this driver from some Drago Dude ?
I remember me talking to Bruce Thigpen about this driver, and the Neo magnets Drago put in it.
Bruce designed the driver.
He told me it was a fine balancing act between a lot of things, and a more powerful magnet was not always desirable ?
So Danny, the driver is ok, but how it is used is the problem ?
Jose, I see you have or had the RM 30's.
I never heard them, but the RM 40's I was glad to see go.
The RM 40's had a thin, disembodied sound, UNLESS I turned the midranges down, WAY down.
Then, they became VERY inefficient, and voices jumped out of 10 inch woofers.
The adjustability of the VMPS product IMHO provides a convenient excuse for the poor performance I experienced.
After all, IT WAS ME who couldn't get them right, LOL
BTW, Brian had me BANNED from his forum when I started asking too many questions.
I started playing/suggesting mods on the VMPS forum, TRYING to make the RM 40's more tolerable.
Next thing I knew, I found myself banned by the owner of Audio Circles.
I ONLY went on the VMPS Forum on Audio Circles, and Brian never complained about me, at least NOT to my face.
He had the OWNER of Audio Circles send me a PM on Audio Circles in the VMPS forum.
The OWNER of Audio Circles flamed me in a PM, NEVER identifying who he was.
I Flamed him right back, presto, I was banned.
I KNOW Brian Cheyney was behind this!
I confronted him with this, and he denied it, but I ain't stupid.
I said "Brian, it is YOUR Forum, and I am YOUR customer"
Stick up for me.
He did not.
EVERYTHING I was Banned for happened in a PM between me and the owner of Audio Circles, who never identified, NOT out in public.
It was all a big set up because I was QUESTIONING VMPS on his forum, LOL
In MY mind, all I was doing was trying to get the POS VMPS RM 40's to sound right.
