It's not uncommon for a company to come along and make the claim that they've reinvented the wheel in audio or video. In fact, every year at the Consumer Electronics Show, I chuckle when some yahoo representing one of these companies comes up to me and begins to peddle their wares. Sure, there have been several advancements in audio engineering over the last few decades, but let's face it—no one has truly reinvented the wheel

The endless search for that perfect speaker to suit all my needs is what makes my job both boring and fun (depending on my mood). In wading through all the hype, I've come to believe that, if you make a claim, you'd better be able to back it up.
Surprisingly, M&K's S-150P THX speaker came along relatively quietly. There was no Don King-type PR rep breathing down my neck, and M&K made no claims initially...yet, for a change, the speaker itself seems to warrant plenty of hype. Read on and discover how.
For those of you who may not be familiar with the benefits of a self-amplified speaker, let me explain briefly. For years now, professional recording studios have used self-amplified speakers almost exclusively. This is due in part to the exceptional accuracy each individual speaker can propagate while working entirely independent of every other speaker—not only in the studio, but within its own enclosure. This is accomplished through the internal amplifier (or amplifiers), which has the luxury of only amplifying the sound or individual frequency being input into it. In other words, if a signal contained within the frequency bandwidth of, say, 17 kilohertz is input, the amplifier will only produce that signal for however brief the amount of time. On the other hand, a standard two-channel amplifier powering a pair of speakers would still need to deliver alternate or identical frequencies to the second speaker simultaneously. Apply this to a five-channel application, and you can imagine the kinds of problems that could occur.
The S-150P THX speaker incorporates a 180-watt amplifier with a frequency response of 80 hertz to 20 kHz (since those are the only frequencies required of the speaker in a THX application). It actually integrates two identical internal amplifiers, which is an optimum application because it allows one amplifier to drive the tweeters while the other drives the woofers. This design enables the output of the amplifier to match the full rating of the drivers. The amp will deliver its full 180 watts to the woofers, as long as no high frequencies exist. In theory, the result is a pure, untainted sound that doesn't compromise details—this is due to the lower distortion and higher damping factor (the amplifier's ability to control the cone movement). The speaker measures 12 1/2 by 10 1/2 by 16 inches and weighs a hefty 45 pounds. There are three 1-inch soft-dome transmission-line tweeters and two M&K-reference 5 1/4-inch polypropylene woofers. All of the drivers are magnetically shielded. The grille used to cover these speakers is attached via four small Velcro patches and is as distracting as Bill Clinton at a NOW (National Organization for Women) meeting. For the life of me, I can't see why M&K decided to use this fastening method, as it is in no way related to the rest of the speaker's fit and finish. M&K assures me that they will eventually incorporate the use of pin-mounted grilles, but not in the near future. After all, the M&K motto has always been, "There's no grille like no grille."
On the back panel, you'll find both balanced (XLR) and unbalanced (RCA/low-level) inputs, as well as a bypass output for connecting an extra speaker or subwoofer. Additionally, there's a switchable, electronic, 80-Hz, second-order, Linkwitz-Riley high-pass filter, which forms a forth-order filter in combination with the speaker's acoustic rolloff and uses a selectable level control with variable and fixed (THX) settings. The speaker comes with a custom stand that adds a very nice touch to the overall look—it also places the speaker at ear level for optimum on-axis response.

The subwoofer I used with the S-150P THX is no stranger to the editors in this industry. The MX-350 THX has been making bass waves for nearly two years. It features a built-in, 350-watt amplifier that drives a duo of 12-inch woofers mounted in a push/pull, sealed enclosure that measures 23 by 15 1/4 by 19 5/8 inches and actually maintains a rather small footprint for a dual 12-inch design. The sub's back panel incorporates enough features to blend into any system, with variable crossover and gain controls marked for THX reference levels. There are also low-level inputs and outputs for daisy-chaining additional subs.
Setup of five S-150Ps and the sub was a snap—it was probably the easiest setup of any THX system I've used so far. The average consumer could set up this package and obtain pretty good results without the help of a certified THX specialist (although I'd still recommend it for optimum performance). Here again, the stands made placement a breeze, and the only things left to connect were the low-level input and power cord. Using the Parasound AVC-2500 THX preamp/ processor, I was able to quickly calibrate the M&K ensemble using the auto-calibration feature and microphone. From unpacking to playback, the system took a record 45 minutes to install in our Los Angeles sound lab.

I began my listening evaluation with the Sheffield Lab reference-material CD entitled My Disc. The first few tracks feature music I've become very familiar with over the last two years. Using this disc, I was able to quickly surmise two things: One, these speakers sound phenomenal; two, I want to own them.

Typically, I'd wait until I heard the cinema performance of a speaker before making such a rash decision, but the impulse buyer in me begged that I purchase this set. Track 6 features an instrumental version of "(Sittin' on) The Dock of the Bay," which is a personal favorite of mine. At 0:57 of the track, a guitar comes in with fairly equal force in both the left and right channels. I noted a tremendous amount of stereo separation and liveliness of the instruments, with detail and clarity that I've rarely heard—and never heard in a speaker at this price point. I quickly forgot that this speaker was first designed as a cinema speaker. I must have listened to my entire Eagles catalog before remembering my initial objective. The evaluation continued . . . .
Starship Troopers was the first DVD in the player. With plenty of dialogue, action, and surround effects, I figured it would give the S-150Ps a good workout. During each scene, I paid particular attention to the rear-channel effects. The S-150P incorporates a direct-radiating design, instead of the traditional, THX-required dipole. I was amazed at how the rear-channel speakers were able to sound as though they were pointing in three different directions at any given moment. M&K achieves this through what they call the active, phase-focused crossover concept. By design, the crossover allows an accurate response in both time and frequency domains, creating a very wide horizontal and vertical plane and thus optimizing a three-dimensional soundstage.
M&K claims that this technology allows each listener in the room to hear the sound as it is meant to be heard, whether they're seated in on- or off-axis areas. I tested their claim by moving away from the sweet spot and trying several different seating positions. It seemed as though, regardless of where I was sitting (or standing), I was indeed able to hear a very wide and accurately staged image, although not entirely as sweet as the sweet spot. For the remainder of the listening evaluation, I chose to sit in the sweet spot to remain consistent with our testing procedure.
The M&K ensemble managed to blaze through Tomorrow Never Dies, Armageddon, and the Eagles' Hell Freezes Over DVD. The soundstage was huge and extremely wide. On Hell Freezes Over, I noted exceptionally accurate vocals and music—the way it was intended to be heard. Here again, there was a very transparent soundstage and three-dimensional sound. Closing my eyes, I could literally place each instrument's location in the room. This speaker was nothing less than breathtaking.
The subwoofer anchored the system well and delivered accurate bass on music, with a kick drum that seemed to hit me right in the sternum. During tracks from Armageddon, each speaker in the system attacked their individual recorded audio tracks. Every sound was so precise and exact, yet everything blended together harmoniously—it was almost a religious experience.
M&K is currently developing a powered tripole speaker to be used as an alternative for the rear surrounds. We hope to get our ears on these by midyear. Even so, the S-150P THX speaker is, without a doubt, the best offering that M&K has ever engineered. Its design, sound quality, and exceptional performance are sure to set a new mark for what other manufacturers should create. If your tastes in music and theater will accept nothing but the best and the price is within your budget, buy this complete system. If it's a few bucks more than you were looking to spend, kiss up to your boss, get a second job, take a second mortgage on the house—do whatever it takes to bring these speakers into your home. Highlights
• Very easy to set up
• The entire room is the sweet spot
• The ultimate theater and music performance
