BALANCED AUDIO TECHNOLOGY
It is a lesser known concept that what separates a pretty good stereo system from a world class system is the combination of high quality equipment that works well together and PRECISE, CORRECT PLACEMENT OF THE SPEAKERS IN YOUR ROOM. With correct placement of the speakers allowing them to work WITH the acoustic response of your listening room, maximum performance is guaranteed and the results are not subtle. That is why our calibration service is included for every client.
The Aluminous Audio story begins by challenging the status quo in loudspeaker design, and ultimately conducting the research to reach new heights in loudspeaker performance. In the course of our research and testing, numerous areas were identified that showed an opportunity to advance the design and the capability of loudspeaker systems. These areas are discussed below.
It is amazing the difference wire makes. We are talking about internal wire, sometimes called chassis wire. We use a specially treated wire that does not require any burn-in. And it is sonically transparent. Additionally, the wire itself has a specially formulated jacket to reduce vibration. This jacketing material reduces distortion that would otherwise be creating micro electronic signals and smearing the original signal. It took a lot of effort and time to source this wire and realize the significance of quality internal wire. Let it suffice to say that internal wire is an important part of maximum performance. That is why we take it seriously and use the best wire.
Cabinets have a significant role towards either reducing distortion or creating distortion. One point is certain about cabinets, the less they vibrate the better. Because of this factor, we use aluminum and other metals in our cabinet designs to reduce distortion. We do not use wood or any soft materials in the cabinet design as they inherently create distortion.
Almost every loudspeaker on the market today and for the last several decades have been ported. There are many reasons for the popularity of the design. We feel that the drawbacks of ported designs outweigh the benefits. Serious drawbacks include port noise, lack of linear response near the tuning frequency of the port, and less defined bass overall. We use fully sealed designs in our products as they produce cleaner bass and do not generate any port noise because there is no port. Yes, they require more amplifier power than a similar ported design, but sealed designs are a must when accuracy is the desired result.
FULL RANGE, ALL IN ONE CABINET versus MAIN SPEAKERS with a PAIR OR MORE OF SUBWOOFERS?
Full range floorstanding designs are the norm. There is one big problem with this approach. The drawback of the design has to do with placing and tuning the speakers to the room for an evenly distributed bass response. With a full range loudspeaker, the placement of each speaker is almost always a compromise between low, middle and high frequency response. Because the drivers are all in one cabinet, the physical location of the low frequency drivers remain in a fixed position relative to the midrange and high frequency driver. Tuning full range floorstanding speakers in the room is a balancing act to achieve the best response, but it is always a compromise. Move the cabinet a little one way and the bass improves while imaging decreases slightly. Move it the other way, and imaging is great but the bass is not quite right. Having a pair or more of subwoofers eliminates this problem entirely. Each main speaker is tuned to the room for the best possible response and imaging, and each subwoofer is independently tuned to the room for best low frequency response. The end result is substantially better sound than full range designs because the loudspeakers are tuned more precisely to the room's natural acoustics.
SPEAKER SPIKES or ISOLATION?
Speaker spikes were likely an invention to attempt an improvement on a flawed design, which was and still is light weight cabinets that resonate. As such, we have no idea why so many loudspeakers utilize a spike system of some kind. Our designs utilize cabinets with adequate mass and no audible resonance, which are then MECHANICALLY ISOLATED FROM THE FLOOR. THIS TECHNOLOGY IS NAMED IVCM, for Isolation and Vibration Control Modules. The result of our design along with IVCM translates into a much cleaner sound in the room as energy is not transferred into the floor itself. With spikes and mechanically coupled designs, a great deal of speaker vibrational energy is transferred into the floor causing it to resonate, as it the floor is essentially a large diaphragm. MECHANICAL ISOLATION avoids "energizing" the floor and results in virtually no distortion from floor resonance.
