![]() This really highlights the follies of providing the -3dB frequency response. Which might be true - look at that last peak on the right. lateral at the higher frequencies.īut even so called "audiophile" whizzer cone full-range devices look horrible: the patent explains why they did the whizzer cone because they thought that the height itself acted as a waveguide to maximize sounds going forward vs. the breakup in the upper frequencies is exactly the problem with whizzer cones. It has an auto-protection circuit so the assumption is that the AlNiCo is still magnetized. Made-in-UK, 130mm full range driver with a whizzer cone and AlNiCo magnet. It's a good thing Canon just focuses on optical equipment now. If you want this to change, please donate what you can using : Just got a notification that the Whopper is being sold for just $2!!! I am going to run out there and get one instead of quality/healthy food which would cost more. Installed the Burger King app on my phone to take advantage of the discounts they offer. If you can pick one on the cheap (I read some people buying them for $150 and such), it is very worthwhile from educational point of view, if not listening.Īnd who doesn't like a cute little speaker like this?Īs always, questions, comments, recommendations, etc. Perhaps the higher ups in the line would not have had the problems this little guy has. It is a good concept for some music but with highly flawed execution. Testing the Canon S-50 was a wonderful exercise in measurements and listening to something different. Vertical response in high frequencies was noticeable though with best response pointing right at the speaker. This would be a great feature for background listening even in mono. It was uncanny how the tonality overall did not change. I then went down to the speaker level and shifted 90 degrees to the side of the speaker. The high distortion did not let me enjoy many other tracks but as far as I could tell, it would add the same but more subtle version of the above to instrumentation tracks I played. Anyone who thinks "reflections are bad" needs to get this speaker and play this track! No, it didn't add any echos. This so called spinorama shows us just about everything we need to know about the speaker with respect to tonality and some flaws:Īh, boy did this track sound good! The wide dispersion gave it more openness, provide more of a "live" feel to this track. So there is some error there.Īcoustic measurements can be grouped in a way that can be perceptually analyzed to determine how good a speaker can be used. I used a relative high number of scan points (> 800) but it still was not enough to characterize the response above 10 kHz. In a nutshell, the measurements show the actual sound coming out of the speaker independent of the room. Both of these factors enable testing in ordinary rooms yet results that can be more accurate than an anechoic chamber. It also measures the speaker at close distance ("near-field") which sharply reduces the impact of room noise. This is a robotic measurement system that analyzes the speaker all around and is able (using advanced mathematics and dual scan) to subtract room reflections (so where I measure it doesn't matter). Measurements that you are about to see were performed using the Klippel Near-field Scanner (NFS). ![]()
