Sometimes the truth comes in a small package
by Mark Fleischmann

Compact Theater 7.1 Speaker System

Let's see. The "small wonders" headline has already been used a thousand times. I may have been guilty of the first few hundred uses. And I'm not going to tell you that the small wonders reviewed here, RBH's CT-5 satellites and MS-8.1 sub-woofer, provide powered-tower slam in a compact package. The laws of physics have their limits and that would be wishful thinking at best. But I can tell you that George Harrison's untimely death moved me to pull his monumental All Things Must Pass off the shelf. This RBH speaker system proceeded to peel Phil Spector's multi-layered production like an onion—lovingly documenting each layer, from Harrison's vocal harmonies to Eric Clapton's omnipresent wailing guitars. Though Iran through the same music with a few other speakers that I know and love, it was the RBH's that produced the most coherent—and, yes, moving—results.

Say hi to a quartet of seven-inch-tall two-way MM-4 satellites, each with a one-inch silk dome tweeter and four-inch aluminum woofer. These drivers, and the gold-nut binding posts in back, are not exactly the cheapest parts that a sat/sub manufacturer might choose to use. They come in a rounded non-rectangular die cast aluminum enclosure that emits a well-deadened thunk when knuckle-rapped. The C-4 center speaker uses the familiar woofer/tweeter/woofer configuration. Inside the sub are two eight-inch drivers, facing forward and downward, and a 200-watt amplifier. Sensitivity is on the low side at 85dB for the sats and 88dB for the center—these satellites want lots of clean power. The sub includes a high-pass filter of 100 Hz for the speaker-level outputs only, line-level inputs can be adjusted between 40 and 160 Hertz. The 5.1-channel package costs $1099. If you prefer your surround in 7.1-channel surround, the similar CT-7 contains the extra pair of satellites for $1349. Utah-based RBH provides a five-year warranty on everything except the sub amp. The system is available in black or white.

In this month's review system was the Arcam AVR200 receiver already reviewed in the February issue. (The U.S. version of this product will be shipping with an improved backlit remote for $1199.) The speakers were well satisfied with its 70 watts times five. Other listening companions included the JVC XV-FA95GD ($499.95), a carousel changer that plays DVD-Video, DVDAudio, Compact Discs, and MP3 files burned onto CD-R, among other things.

Of course, not too many people play either musty old George Harrison LPs or DVD-Audio discs. But lots of us play CDs. The RBH's, the seven-disc JVC changer, and seven new CDs all just happened to arrive in my review studio at virtually the same moment. You can guess what happened next: I loaded up the changer with the new June Tabor album Rosa Mundi and three two-disc sets of classical and rock music and let it fly. The Tabor CD—a celebration of the rose dominated by a strong group of traditionally derived songs—provided ample opportunity for the RBH's to stumble. But the speakers did a surprisingly good job of conveying the subtle dynamics of the recording and vast inky black spaces between the English singer's melancholy vocal sonorities and the spartan piano, viola, and cello that accompanied her.

The weirdest thing I listened to was the two-CD repackaging of Bach Hits Back and A Cappella Amadeus by the Swingle Singers. At the sound of this name, people who don't quite remember the I 960s stir and look slightly perplexed. People who do remember the I 960s start grinning. The Swingles became a camp sensation with astonishingly disciplined eight-part scat singing of familiar tunes by Bach. RBH's satellites and subwoofer shrewdly navigated the jazzy sonic sculptures on these two 10-year-old releases. Such vocally dominated music is actually quite hard to reproduce perfectly as sopranos, altos, tenors, and basses race up and down scales, from one end of the frequency spectrum to the other. One swollen note would ruin the whole cascade. But that note never came.

Only when the Swingle basses reached down into their bottom octave did the system betray an audible quirk—not in tonal balance, but imaging. The lowest notes would jump right into the sub where I could localize them easily. The same effect was audible on Nick Drake's Pink Moon whenever Drake's voice hit a percussive consonant. It was certainly not a problem with, say, the bass line in the opening theme of The Sopranos, which came through in all its ominous testosterone-fired glory, but it was mildly disconcerting with music dominated by resonant male voices. With the volume just one-third up, the sub level wasn't excessively high, so the cause must have been the relatively high crossover point of 100 Hz between sats and sub (versus, say, the more common 80 Hz recommended by THX). Satellites with four-inch woofers tend not to have full-range bass response. Therefore the sub had to fill in the mid- and upper-bass. After a while I got used to this inevitable effect of speaker miniaturization. There was never a moment when I put aside a CD thinking: "No, the RBH's aren't up to this."

In fact, it's probably no accident that I reviewed the RBH CT-5 and MS-8.1 with music that I actually listen to as opposed to relying on my faithful, familiar test tracks. I got more day-today musical pleasure out of these little revelations than I've gotten from any other small-sat system. And there's no need for veiled warnings like "better for movies than for music." This RBH speaker system handled everything I threw at it and did so competently (quite often, brilliantly). These satellites are out of this world.
