Extraordinary claims made about Rythmik Subwoofer !!

[barfind]

No I didn't think you would be interested in talking to the owner direct................rather take cheap shots, and make claims about it. Seems a bit cowardly to me.

That doesn't make me a coward at all. He is quite welcome to come here and debate the issue on an open forum for all to see. It started on this forum and should end on this forum !! I don't have anything to hide because I'm not the one making the claims If I'm wrong about anything I have said or have misinterpreted what I have read then I will be the first to eat my own vomit unlike some others here who can never admit that they are wrong about anything

That is totally absurd !! What would a lawyer know about technical issues anyway

Anyone you don't want to denigrate? guess you are just brighter than everyone.

By the way I am 1 year from my J.D. with a math degree prior to that and seven years of teaching math and science. I know a number of lawyers with considerably more technical training than you have yet, grasshopper.

Yes, it does.

Again with the insults.

It doesn't make any difference what price something is. There are many people that have been scammed by low cost items which weren't fit for their intended purpose or didn't meet the advertisers claims.

Like I said before there has been an exaggerated claim made for this subwoofer which has been contradicted by the test results from an independent tester.

Now either back up this claim or have it removed from the website !!

Alternatively if you don't agree with these test results then please provide alternative test results and state the conditions under which they were made.

And, yet again, you ignore the salient points that I made in my post and pick out one bit you don't agree with to snipe at. And, yet again, you re-state your claims with one 2yo test to 'prove' it (and that you don't understand the results for). In this case the burden of proof is still on you... why should I pay to test out something that you contend? The onus of proof is on the complainant.

I don't care if you get your degree off the back of a cornflakes packet you don't even know anything about me which just makes all of your comments all that more inane !!

Most lawyers wouldn't even know how to replace a light globe. They are just to busy making money from weasel words.

And wait it has just been brought to my attention there are even more exaggerated claims on the website !!

Unlike conventional subwoofers, the distortion is very low. In fact, it is lower than some high end amplifiers.

Which high end amplifiers are these ?? They must be pretty bad amplifiers LOL

!!!!!!!!!!!!ENOUGH!!!!!!!!!!!!!!!!

Snoopy, you are like a dog with a bone....... give it a rest! You prove very little except that you are very stubborn, and very young.

The product is apparently good and draws no complaints. Be careful lest the manufacturer takes you on....

As far as I'm concerned any vendor who either directly or indirectly attacks their competition is them self open to be challenged.

How about the Cary CAD 280SA V12? At 2W it was hovering around the 3% distortion, something which the DS1500 could probably beat at that level - not that I've seen the measurements for the DS1500. At 2W, I'd say the DS1500 is producing less that .5% at 20Hz.

Do I need to spend another 2 minutes searching for another amplifier to meet the "some" criteria - no, one is enough for you, so it must be for me?

Seeking attention by "bashing" a manufacturer who caters to the DIY market, on a DIY forum, is pretty low.

Hi,

maybe I don´t agree with the way snoopy brought his points to attention, but then, that´s semantics. But I agree with his base line which is btw just about exaggerated claims and not about the real qualities and capabilities of the product itself.
And this line reads: "A well designed servo subwoofer will achieve distortion levels under 3% under the same conditions." Same conditions here: @20Hz, @100dB.
Since Rythmik claim this behaviour in a genearl way, one should assume that every(!) of their Servo Subs is capable to reach these goals. The cited measurements from the HT-Forum do talk a different language indeed. They don´t differ as dramatically as it is claimed from other good subs working wo motional feedback. Since the quality and distortion niveau of the driver (and the sensor element) is of main importance, it´d be interesting to see how the sub performed wo feedback. I´d say a comparison with other subs, featuring other casings, drivers and amps won´t really proove anything. From what I´ve learned reading many papers about MFB is that a reduction in distortion of up to 50% is realistic. With this rule of thumb a distortion level of less than 3% under the above cited circumstances would be out of reach. But then.....would even the high distortion values be audible anyway? I don´t think so. So its talk about a ´exaggerated´ claim about a parameter that is of very low importance soundwise.
I find one feature of the Rythmik sub way more remarkable and that is the low value of the group delay. The lower the GD the more precise a sub sounds. But usually a driver that is eq´d to a very low F3 exhibits large GDs (>40ms). It must be realized, that the filtering adds the major part here, while the driver itself (in a CB) typically exhibits less than 10ms GD. Maybe this is the real advantage of the servo sub?? Low GD AND low F3?
