Hi Srajan, in your review of the Diesis Ludos speakers, you include several musical examples. The first one is a recording of the "Adagio" of The Concierto de Aranjuez being reproduced by the Diesis Roma which, I presume, you recorded while you were there at the HiFi Deluxe audio show. It is the only recording in the review for which you did not give any information. If you happen to know which recording that is, could you please let me know? By the way, those recordings are all very good. I am sure that they are not done with a smartphone. Could you share what recording equipment you use to make them? Regards, Peter
The first video is from Diesis so I don’t know the recording they used. Hence I provided no information; plus I didn’t review the Diesis Roma in Munich. All the other recordings are on YouTube and not mine. They’re simply a way to let people stream some of the same music I used during the review; whilst reading the review. That makes it easier to fully appreciate some of the sonic descriptions. As to recording quality, most of my examples tend to be better because these artists paid attention to it (and also for it) but I also listen to quite poorly recorded stuff. At times I will deliberately highlight a lesser recording to demonstrate whether a particular component's quality still matters then. I recently did that in the Mutec review with an Amr Diab track. If a hifi only sounds good on premium fare and makes everything else unacceptable and no longer fun, it's counterproductive. So mixing it up on recording quality is key then. Srajan
A related question, please. In the same review, Diesis specify their bandwidth at ±8dB. I've never seen this before and assumed ±3dB was the standard. Peter
Correct. Unless theirs is a typo, Diesis have used a looser tolerance. Then if we translate the currently published 37Hz-26'000Hz spec to -3dB, we might perhaps arrive at 55Hz – 20'000Hz? If it is really important to you, you could ask them. As my review explained, the figure 8 cancellation of out-of-phase data at the edges of an open baffle makes for less bass extension than raw woofer diameters might suggest. Even though the Ludos uses dual 10-inch woofers, the small port-loaded widebander in the Camerton Binom-1 just reviewed actually goes lower. The flip side is, it won't move anywhere near the same air. So it's six of one, half a dozen of the other. Srajan
