Robert,
That was Lars Kristensen.
Two men are responsible for Raidho's speaker and driver designs - president and chief designer Michael Børresen and co-designer/sales manager Lars Kristensen.

Hi Lars,
Sorry about confusing you with Michael. I look foreward to seeing you in a future show.

Hi Mark,
I do not think that I was clear about the "clipping", let me explain what I was referring to.....and it really has nothing to do with the speakers.
It is two different issues.
The first issue is what you are explaining accurately, if you overdrive the speakers because of the small drivers you can pop the woofers. For all that are not familiar, this "pop" does not hurt the woofer, it is just telling you to turn down the volume just a hair. This has nothing to do with the amplifier running out of watts/steam, it is that you are just pushing the drivers too hard.
(Don't forget the size of the drivers that are employed in the Raidho speakers is why they sound the way they do, put in larger drivers and you lose the magic....easy choice that Michael and Lars made from my perspective)
But secondly, if you try low power amps like 25 watt tube amps or even 50 watt tube amps in a really large space and you drive them up to say 100 db or higher, they actually do NOT "pop" the drivers at all. But what you will hear is a distortion in the higher ranges of either an electric guitar, a male operatic voice, or certain female voices ie, Patricia Barber when she really pushes a certain note with her daunting vocals. The distortion, which you have to listen for, as it is not always totally obvious because of how gently tubes distort, is the amp just running out of power and clipping. With tube amps it does it quite gently, but it does distort and this is clipping of the amp.
This "clipping" has nothing to do with the size of the drivers or over driving them. It is like you say "phsyics" in this case as well.
In either case all you do is turn it down the volume ever so slightly and you are still probably at close to 100db, maybe 95db with specific demanding source material that has a certain type of dynamic spike in the recording, which is usually louder than you would normally be listening to anyway.
Hope this clarifies, for me personally I now understand why and what the speakers or amps are doing and it is easily understood because it is physics. Now it's time to just sit back and to listen to the wonderment of the Raidho speakers.....again, for me, ymmv.
A gift for you Bob,

Hey Brother.....Hope all went well in Florida yesterday! The video is very nice....captures the sound pretty nicely, right?
Hello, I'd like to make a small comment to the debate...
When we designed the Raidho drivers, The primary focus has been on reducing dynamic compression and optimizing transient response and micro resolution. It would be quite easy to build drivers with more dynamic damping allowing them to be driven harder by letting them run out of magnet force at large excursions and loading the driver harder at High SPL’s But at what cost…??? Reduction of base resolution, reduction of scale and having a less vivid life-like speaker… I my book that is not an option
For me there is absolutely no question about what choices to make. I made the choice to make 99% of my records sound best possible rather than compromise in order to suit a few over produced tracks.

Michael, I think you have created one of the finest speakers I've heard. Please correct me if I'm wrong,but I was under the impression that the bass drivers in the D series are not bigger because of limits in manufacturing. I personally think if you had the machines to produce a 6" bass driver you would still have everything you desire,and no bass driver popping. I am no engineer, and you are one of the finest. I look forward to your thoughts !!

Well said Bob !!
Welcome to the forum Mike! Loving my D3's and you were right about the Raidho/VAC synergy. It's a good one!
Haha yes when talking about a speaker line , who better to have in the conversation than the guys who make them!!! Welcome !!!
Guess we can't say anything bad about them now lol!!!!
Seriously I don't think I could go wrong with any of them that I heard , I just wish they were a little easier on my pocket!!!! Although what you get with the c1.1 for the money would match up and in most cases better a lot of very pricey monitors that I've heard in the past .
Cheers to all!!! D1's on snapper I can feel is going to be a match made in heaven. I can't wait to try it!!!!!!

+1. Way cool to have Raidho here on our forum.

I know at one time that Raidho was working on a mini monitor in the under $10,000 range. I think that the project got put on hold as they developed the D series.
Me -- I hope they have time and are able to produce something in that range.

I see the x monitor out there. Was a used pair for $4k last month. But I'm guessing a drop off in performance. And someone has mentioned that to me as well.I know at one time that Raidho was working on a mini monitor in the under $10,000 range.

Update for ANYONE that has visited my studio over the last few months during my "honeymoon" with my D3's and especially with the Aboslare 52 Watt SET amps. Just since this last Sunday, the combination of my D3's and Absolare SET's has CHANGED SIGNIFICANTLY. I can't describe the differences as it is now an entirely new system. I made two changes - the first putting 1/2" granite 20" X 20" under the speakers, which was only required due to my specific flooring, most D3 users would NOT need this "granite upgrade". More importantly with the Absolare amps, I switched from the 4 ohm taps, which I had been using all along to the 8 ohm taps. Btw, in the tech specs section of the D3' on the Raidho site the impedance for the D3's is listed as 3.9 ohms. In talking to Lars today he confirmed with me that this is not accurate and was a typo mistake. He is correcting it and it will probably say 5.9 ohms. I just measured my D3's and they show 6.6 ohms. Anyway, I never would have tried the 8 ohm taps on any speaker that measured 3.9 ohms, 6.6 is a different story. And for whatever reason the 4 ohm taps on the Absolare amps, now hearing them for the first time this past Sunday on the 8 ohm taps shows that there was a GROSS mismatch with using the 4 ohm taps. I am truly amazed by the difference.
I am telling ya'll to come on back and hear this new combination as it's an entirely different planet.
I also have recently become an Emm Labs/Meitner dealer and will have the Emm Labs Dac2x and the TSDX transport here in a few weeks. Additionally I will have a full set of Ansuz cabling and Ansuz accessories SparkZ/DarkZ here in a few weeks if anyone would like to hear them or try them in your system.
