"Blind reliance on measurements can be misleading ‐ one needs to tie those measurements back to subjective perception. The room response gives a picture of the steady state SPL, where sound generation and sound dissipation in the room have reached their equilibrium." -Linkwitz The resulting curves must not be taken as a 1:1 representation of what is heard as loudness at different frequencies. " The room response must be averaged to recognize trends in the summation of direct and reflected signals at the microphone. So off-axis listening is probably in order - as seems to be common for budget/more mainstream speakers. That said, the on-axis is still tilted a little up. This suggests that the ideal target slope may depend on the loudspeaker’s directivity." Test One includes mostly 2-way designs whereas the larger sample includes several 3-way and 4-way designs that tend to have wider dispersion (hence smaller negative target slopes) at mid and high frequencies. "The degree of tilt varies among curves for Test One and the larger sample. I know Amir found this bright, and the predicted in-room curve tilts downward less we normally expect But in case anyone is thinking about writing it off for being too bright right away, one thing to keep in mind about the predicted in-room curve is that it in general, it seems wider directivity speakers may perform better with less of a tilt in the PIR. Love that wide directivity and surprisingly good vertical control too. Good stuff! It seems the claims Infinity speakers are "a poor man's revel" may just hold true. Please help me stay happy by donated using : They are not expensive to make but you know me, any cent out of my pocket makes me depressed. My wife has started to make masks so that we can wear them when we have to go out (e.g. You can have a very enjoyable system with it despite the low cost.Īs always, questions, comments, recommendations, etc. So overall, if you like slight zing to your music or can EQ to remove that, then I am happy to recommend the Infinity R162. The rest of the performance both objectively and subjective is very good and not at all that of a cheap junk speaker. Whether on purpose (to sell better in showroom) or not, the elevated highs are a bit of an issue but fortunately that cam be tamed with equalization. The Infinity R162 definitely seems to have benefited from good design. Overall, the woofer and bass performance is the start of the show. Indeed, no matter how much power I pumped into the R162, it handled it without bottoming out! However, the M20 could not remotely play as loud as the R162! Its woofer would break up at much lower levels than the Infinity. I can't help but think how good this speaker would be with a simple in-line resistor with the tweeter to kill off some of that excess energy.įor comparison, I put in the Revel M20 in the same spot and it was a relief to hear a less elevated highs.
This so called spinorama shows us just about everything we need to know about the speaker with respect to tonality and some flaws: In a nutshell, the measurements show the actual sound coming out of the speaker independent of the room.Īll measurements are reference to tweeter axis with the woofer grill left on as indicated Frequency resolution is 2.7 Hz.Īcoustic measurements can be grouped in a way that can be perceptually analyzed to determine how good a speaker can be used. Both of these factors enable testing in ordinary rooms yet results that can be more accurate than 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). If you care about country of manufacture and can't read it above, it is China.
