Stand Loudspeaker Reviews

Late last year, when I first heard of the Music Hall Marimba, I was happily surprised: One of my favorite hi-fi manufacturers had finally introduced its first and (so far) only loudspeaker—and it was seriously affordable at $349/pair. I wanted to review the Marimbas right away, but grumpy old Sam Tellig beat me to them.

For years, I have espoused the use of the same speakers (except subwoofer) in all positions for multichannel music. To have no speaker in the system contributing a different voice to the choir seems as intuitive as having the room acoustics not color the sound. Of course, this still doesn't guarantee perfect timbral match—positioning and room acoustics usually impose some unique characteristics under all but the most perfect and symmetrical conditions. You can hear tonal imbalances even between the left and right speakers of most two-channel systems simply by switching pink noise between them. On the other hand, there's no reason to superimpose on these unavoidable differences the additional imbalances inevitable with using different speakers in a multichannel array.

One of the recurring themes of this column has been my search for servers that will support the playback of high-resolution multichannel files with DSP for speaker/room equalization (EQ), as well as the format conversion and downsampling that are often part of those processes. Because most EQ software is PCM-based, format comversion is needed to convert DSD files to PCM. In addition, because most EQ products work within a limited range of sampling rates, PCM files sampled at high rates may have to be downsampled before being subjected to EQ. Those of us who use home-theater preamplifier-processors and audio/video receivers (AVRs) should be familiar with such constraints.

When reviewing affordable speakers, it's critical to have benchmarks and comparisons for various price points. Inexpensive speaker designs are exercises in tradeoffs and compromises, especially for the least costly products. In all of my reviews, I try to compare the speaker in question with other designs close to the review sample's price, chosen from my list of previously reviewed speakers. From time to time, if a speaker particularly impresses me, I ask the manufacturer if I can keep the speakers around a while longer, so that it can serve as a comparison reference for a certain price point. That's not to say that any speaker I don't keep around is less desirable—there's just not enough room in my house to keep a sample of every speaker I like. An audio reviewer's wife puts up with enough as it is.

Now Hear This (NHT) was founded to produce low-cost loudspeakers a breed apart from the mass-market variety often found at the lower price points. Co-founder Ken Kantor has a long history in the hi-fi business as a designer at Acoustic Research, NAD, and as a design consultant to some large Japanese manufacturers. NHT's line ranges from the $180/pair Model Zero to the $1200 Model 100.

At $480/pair, the Model 1.3 is midway in NHT's product line. Finished in a gloss-black high-pressure laminate, the 1.3 is elegant, even beautiful, and is distinguished by its unusual angled front baffle. This design means that the rear baffle is nonparallel to the driver, thus reducing the amount of internal cabinet energy reflected back toward the woofer. This is said to improve imaging and midrange purity by reducing comb filtering. In addition, the angled baffle puts the listener directly on-axis with the loudspeakers pointing straight ahead. This increases the ratio of direct-to-reflected sound reaching the listener and further improves imaging.

What makes someone a good hi-fi reviewer? A fine critical sensibility? A good technical background? Ears? Eyes? Nose? Throat? So many different people are reviewing audio gear these days that it's downright impossible to characterize a good reviewer. But I do know that Beavis and Butt-head would make killer hi-fi reviewers!

NHT's Xd system is what audiophiles have been saying they want: a matched loudspeaker system that optimizes the performance of its components for a real-world domestic listening environment. But with their dollars they've voted against just such systems for years. If we put our money where our mouths are, active speaker systems such as Meridian's DSP or those used in recording studios would dominate the High End.
