Yamaha HS8S Active Studio Subwoofer

Complete your monitoring setup with this powered subwoofer. With lows down to 22 Hz, the 8-inch HS8S sub complements Yamaha's full-range HS monitor speakers.

The Yamaha HS8S is a 8" bass-reflex powered subwoofer that delivers low frequencies down to 22Hz.

When choosing reference monitors for mixing and music production, accuracy is the prime consideration. Speakers that sound "good" on first impression may not necessarily be accurate. What you really need is an honest reference for your mix, rather than monitors that have been tweaked or colored to deceptively sound impressive.

The HS series reference monitors have been created by Yamaha's studio monitor engineering team to deliver exceptionally flat, accurate response that you can trust. Unlike "monitor" speakers with exaggerated bass and treble that make a good first impression but can't be relied on for accuracy, the HS series were designed to be true studio reference monitors in the tradition of the legendary Yamaha NS10M. The HS Series features transducers that achieve astonishingly smooth response over a wide range of frequencies.

Whether you're mixing for stereo or 5.1 surround, mixes that sound good on Yamaha HS series reference monitors will translate accurately to the widest possible range of reproduction systems -- which is engineer-speak that simply means they'll sound good on anything. And that is the ultimate goal of any reference monitor. It's also worth mentioning that the HS-series monitors not only sound great, they look great, too.

High-performance Speakers and Mounting System

The elegant white-cone speakers used in the HS-series monitors deliver read more superlative audio performance that is further enhanced by a carefully engineered mounting system. A system of screws and a specially designed mounting ring eliminates spurious vibration and resonance, allowing the speaker to deliver its full sonic potential. Another feature that boosts woofer performance is a magnet selected to produce accurate, solid low-end response. The tweeter frames employ an advanced smooth-contour design that minimizes losses so that high-frequency details come through with remarkable accuracy. The extra thickness of the tweeter frame also minimizes resonance that can interfere with high-end clarity. The overall result is extraordinarily smooth, accurate response throughout the audio spectrum.

The Benefits of Built-in Power and Bi-amplification

Powered, bi-amplified monitor speakers simply make the most electrical and sonic sense, and that's why they have become the first choice of sound professionals the world over for near- and mid-field monitoring applications. In addition to the obvious advantage that you don't need separate power amplifiers, the fact that power and speakers are integrated in one unit means that the amplifiers can be perfectly matched to the characteristics of the speaker units used so you get consistently superior performance with any source in just about any listening environment. Bi-amplification means that separate power amplifiers are used to drive the low-mid and high-frequency speaker units, and this eliminates interaction between the units as well as the response and phase anomalies introduced by passive crossover networks. Both speaker units can function at optimum performance levels for correspondingly high overall sonic quality.

Large Magnets in an Advanced Magnetic Circuit Design

One feature of the HS-series monitors that you'll hear but are not likely to see is the extra large magnets. In combination with an advanced magnetic circuit design these magnets provide a powerful, uniform, tightly controlled flux field that results in exceptionally smooth response and dynamic capability over a wider frequency range.

Portable, Versatile Monitoring for Your Audio Workstation

All you really need for top-class stereo production capability is a good audio workstation and a pair of HS-series monitors. A system like this is not only portable and extremely easy to set up anywhere you need it, it can deliver outstanding monitoring performance that will let you get your mixes just right. The response-control features of these monitors let you tweak them for the best response no matter where you set them up.

Serious Surround Production

Although stereo is still the most common format for basic music listening, 5.1 surround has become the audio format of choice for today's advanced visual media, and is beginning to be recognized as a superior vehicle for pure musical enjoyment as well. But to properly mix and produce surround sound you need a good 5.1 monitoring system. The HS-series speakers and subwoofer are the perfect choice if you want competitive surround-monitoring performance without having to spend big-studio megabucks to get it. Combine five HS50M or HS80M powered near-field reference monitors with one or more HS10W subwoofers, and you're ready to produce and deliver state-of-the-art surround sound.

Optimum Response In Any Room

Speaker response can vary greatly depending on the size, shape, and surface acoustics of the room in which they're used, as well as how they're placed within that environment. The HS50M and HS80M give you extra room-matching and speaker placement versatility with ROOM CONTROL, MID EQ, and HIGH TRIM response control switches that are specifically designed to compensate for common acoustic deficiencies and monitoring needs. The ROOM CONTROL switch, for example, can be used to compensate for the unnatural low-end exaggeration that usually occurs when speakers are placed close to walls or in corners. The MID EQ switch gives you subtle midrange boost and cut options in addition to flat response, while the HIGH TRIM switch offer the same type of response-tailoring capability for the high frequencies.

"A must if you are using the smaller HS monitors"

This speaker is perfect for small to medium size studios. It's clean, powerful and accurate. The built in amplification is a perfect, distortion-free match for the speaker and it delivers plenty of loud volume if you want it. I bought this to compliment my HS5 monitors where the low frequency response is a not very deep 54Hz. It rolls off very quickly at the low end. By themselves, they are fine for monitoring vocals, electric guitars and most acoustic instruments. I work primarily in electronic music and strong bass response is an absolute must for me. Together, they sound absolutely amazing, especially when I'm cranking out earthquake level bass from my analog synthesizers. Even when I'm doing that mixed with mid and high frequency sounds, there is no distortion or coloration throughout the entire frequency range. You're hearing exactly what you are supposed to be hearing. Hookup of this configuration is extremely easy. I think this subwoofer would be an excellent compliment to any small near field monitors.
