A proprietary Dimension module composed of a 1” XD Soft Dome tweeter and 3” Dimension driver covering a specific frequency range mounted in the rear of the cabinet combines with the front mounted drivers to effectively imitate the 70% reflected to 30% direct acoustic ratio of a live event. The result is a speaker capable of 3 dimensional sound.
The 3” Dimension Driver and 1” XD Soft Dome tweeter compose the Dimension Module. The module is mounted into the back of the tower loudspeakers to create a reflected sound and create a greater effect of spaciousness and realism, or 3D sound. These injection molded cones are equipped with a bullet dust cap that corrects time alignment for the most accurate reproduction of midrange frequencies.
XD Soft Dome Tweeter
The 3D Series employs a complex tweeter assembly that consists of three main components. First, the Xtreme Definition Soft domes provide incredible accuracy in the high frequency range and substantial power handling. Secondly, it is fitted with a device called the Phase Shift Corrector which reduces resonance and distortion in the high frequency range. This is the cross pattern located directly in front of the tweeter. Third, the entire mechanism is housed in a horn loaded faceplate to improve efficiency. The combination of these ingredients results in the most natural sounding high frequency reproduction over a wide listening area.
PolyXD Woofer and Midranges
A speaker must provide more than just clear high frequencies and the Stage woofers deliver high-impact yet natural bass. Injection molded, polypropylene woofers are infused with a remarkable combination of materials such as graphite and mica for the added strength needed to maintain its shape during the deep bass passages. These cones are mated to rubber composite suspensions to allow a very smooth, linear motion for improved transparency and practically non-existent distortion. This incredible driver sits in an injected copolymer basket that is impervious to the ringing associated with metal baskets.
Woofers are equipped with enormous dust caps to help reinforce the strength of the cone and allow it to maintain its shape in even the most punishing bass passages. Midranges are equipped with a bullet dust cap that corrects time alignment for the most accurate reproduction of midrange frequencies.
The uncompromising cabinet design features rigid MDF (Medium Density Fiberboard) construction and bracing for its strength and inert acoustic characteristics. Much of the rigidity of the new cabinet can be attributed to the elegant shape, it is a known natural occurrence that a curved surface is more resistant to bowing and flexing and can sustain a higher load. The large port increases smooth airflow and reduces noise causing turbulence. A speaker free of distortion and resonance requires more than a rugged cabinet with great sonic characteristics, however, as the drivers and crossover components all play an equally vital role.
The MaxBass port system permits greater air flow released from the cabinet with no turbulence, resulting in tight, deep bass without distortion.
The crossover is the first stop of the incoming signal and plays as vital a role to the performance as the drivers and cabinet. The Stage series uses the same quality of crossover components in all models, guaranteeing that the overall sonic characteristics such as timbre and tone are maintained throughout the line. Designing them simultaneously assures a natural step and demonstrable improvement in each upgrade through the series, offering deeper bass and better power handling. Mix and match them with home theater receivers and get perfectly timbre matched systems.
With this 3D Sound diagram, the front-firing speakers are equipped with a rear speaker that reproduces sound creating the acoustic effect that your in a large room such as a theatre or concert hall.
Understanding How We Hear
One of the best ways to appreciate our technology is by understanding how we hear. Research proved that in a live musical environment, approximately 30% of what we hear is direct sound while 70% is reflected from walls, ceilings and floors and only reaches our ears a few milliseconds after the direct sound. Soundstage engineers recognized that a speaker capable of recreating the correct direct to reflected ratio would therefore reproduce sound with far greater realism and faithfulness to the original instrument and environment.
The reflected sound ( figure 1) creates the effect of spaciousness and helps us determine the dimensions of our room and what we hear. You do not have to be a speaker expert to appreciate or understand this but this example may help clarify the point further.
You do not have to have your eyes open to know if you are standing in closet or in a stadium, you can tell the size of your surroundings by how your voice will sound. The reflected sound reaches you quicker in a small environment like a closet so your brain tells you that based on what you’re hearing, you’re in small area. In a stadium where the reflected sound takes longer to reach you, your brain tells you that based on what you’re hearing, you’re in a large environment.
3D Technology: How it works
The floor standing speakers in the 3D series have a rear mounted Dimension Module which includes a 3” midrange and 1” tweeter that help create a deeper, wider, soundstage than any conventional speaker. Soundstage 3D speakers sound so real you’ll swear you’re right in the middle of the action of your favorite movies or in the front row at your favorite group’s concert.
The Dimension Module in the rear of the soundstage 3D series speakers, working in tandem with a carefully engineered crossover topology, create a three dimensional acoustic effect that takes the listening experience from the dark ages of basic stereo into a startling new era of 3 dimensional sound.
Every other traditional speaker is designed to create a shallow stereo, typically limited to the space between them. This is the sound that most are used to form a sound system but this is not at all what we experience in real life, which is why you can always tell the difference between something recorded and something live.Try to remember any live performance where you could close your eyes and pinpoint performers' locations exactly in space and separate from each other. Never does a band or orchestra stand shoulder to shoulder across the width of the stage. They are not only more spread out but also layered, where one performer might be situated behind or adjacent to the next. A Soundstage 3D series tower can recreate this effect but a conventional, forward-firing speaker cannot. Its lack of rear firing reflected sound makes this impossible. A forward-firing speaker will create the flat, 2 dimensional stereo sound effect which is not as realistic as 3D, lifelike sound.
With this 2D Sound diagram, the sound is unrealistic andconfined to the width and depth of the speakers like you're in a tight confined space such as a closet.
Our data showed that a conventional speaker (figure 2) had opposite ratios of direct to reflected sound, or 70% direct and 30% reflected. Such a speaker could only create the two dimensional stereo effect but could not mimic a live performance because it’s effect lacked the extra dimension of depth.
The drivers mounted in the rear of the soundstage 3D series speakers, working in tandem with a carefully engineered crossover topology, accurately creates this ratio and live sound effect. We concluded that a rigid, rounded cabinet with specially designed drivers would be the right technology to pursue, immersing the listener in a natural Soundstage. This signaled the dawn of 3D series technology, taking the listening experience from the dark ages of basic stereo into a startling new era of 3 dimensional sound.
