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). The music makes sense to us even if some of the finer elements are overlooked.If you care about country of manufacture and can't read it above, it is China. Still, these JBLs manage a nicely balanced presentation that communicates the essence of the music well. Instrumental textures aren’t so intricately drawn, nor are low-level dynamic nuances tracked with as much skill as the class leaders are capable of. Rhythmically things are precise enough to convey the momentum of the music, though not in a class-leading way.ĭo the L52 Classic deliver the most detailed sound we’ve heard at this price? Not even close, as we find out when we listen to Mahler's Symphony No. Even the bass performance is pleasing, sounding more powerful and punchy than the speaker’s compact dimensions suggest.Ĭobain’s vocals are rendered in an appealingly forthright manner, and the overall presentation is far more full-bodied and muscular sounding than we’d expect from something that’s barely bigger than a shoebox. The sound is fun, and can even be thrilling when the music demands. There’s a good amount of attack and enough ability to organise the song’s various musical elements into a cohesive and musical whole. They’re happy to charge along full throttle delivering Come As You Are with real verve. We listen to Nirvana’s Nevermind and the L52 Classic sound right at home. They sacrifice a degree of sonic sophistication and refinement compared to class leaders such as KEF’s LS50 Meta, or even cheaper alternatives such as the B&W 606 S2, but offer partial compensation with a lively and punchy presentation that entertains. The L52 Classic are outgoing and enthusiastic performers. ![]() There’s a good degree of overlap between these and the bigger models in the range when it comes to sonic character. These speakers produce enjoyable results once up and running. We also prefer firing these JBLs straight ahead rather than strongly angling them towards the listening position, though there’s no harm in trying that if necessary to get a properly focussed and solid stereo image. While the L52’s small size may encourage people to put them right up against a rear wall, we found them to perform best when given a little room to breathe – starting around 40cm into the room – and positioned well away from room corners.
