Danny Richie "fixes" the Linkwitz Arion loudspeaker

I’ll tell you why. It’s EASY to take apart someone else’s work. Danny has been doing that since he started, repairing other peoples speakers, years ago. He was a VERY harsh critic, of the late Brian C. of VMPS.

They use to go at it, because the fix, was usually, someone else put the speaker kit together incorrectly, or it was the cheapest kit VMPS sold and a few mods, tightened them up..

I saw a 35 lb speaker, come out weighing 60 plus lbs.. AND a big article on how it was fixed... I laughed about the BIG pat on the back about a speaker that was one of Brian’s earliest kits, and upgrades that had not been installed. The 3.00 dollar fix turned out to weigh in at close to double the weight. When a piece of light or expanding foam was the answer, and a different cap, installed in the XO. Late 80s and 90s
I knew Brian C. very well. He was a really good guy. I personally like his speakers above ALL others. STILL do.

I’ve had text exchanges with Danny. He is an easy going guy for sure.
The crew he works with are, over the top (Jay) cabinet guy. I’ve owned the 123 LS6 and own his servo bass units, currently.

Now ask me about the TEC in the plate amps he uses for the servo system, and I’ll tell you another clever tale, about the guy that modifies them. How the servo REALLY works.. How good are your programming skills, because that is what it boils down to... Mine.. ok at best or use to be, C, C++, Basic, Visual Basic, heck even a little assemble code. a master batch file writer. :-)

I have NEVER done a job, that I didn’t think a little change might not hurt.
When folks say "it went perfect", I always say "wish that would happen to me". I’m my own harshest critic.

I ALWAYS take pause with the HAUGHTY.

Regards to all

I wish I had an Orion to measure, but DR accuses Linkwitz of a number of bone-head mistakes, which I doubt, not because I’m a huge fan boy but because the late Dr. Linkwitz was one of the most meticulous speaker designers I’ve ever ever seen. Without measurements I can’t prove it, but there are not a lot of speaker designers I know who took as much care in every aspect of their design as Dr. Linkwitz.

One thing I find kind of curious is his discussion of compensating for the rising impedance of a tweeter: In real life it’s almost never done nor is it needed.

You compensate for the rising impedance of a woofer because not doing so can throw off your low pass filter design. It’s written about here:

However, since tweeters have no low pass filter, just a high pass, it’s a moot point, unless you have a truly high output impedance amp (i.e. tube) which can make it seem brighter, but just a tad.

@bdp24 he most certainly was aware of room nodes, he just believed there was a better way of dealing with them than using bass traps.

I'm of the same opinion. If you don't make it everywhere, you don't have to control it everywhere.  Rule number 1. controlling the bass, is 90% of the answer, when it comes to distortion... in ALL 7 of the frequencies ranges I address. sub, bass, MB, Low mids, mids, highs and UHF.

They are addressed normally by room treatment, with the exception of 100hz and below.. Traps kill what you really don't need to be making, to begin with...
