Gallo hi-fi system - A'Diva, Due and Micro speakers with MPS 150 powered subwoofer

Support: FAQ's - product support

Q: Where can I hear the Nucleus Micro, A'Diva, Dué and Reference 3?

A: Please check the 'Find a Dealer' section of this site.

Q: Can I mix Micro, A'Diva and Dué speakers as part of a Home Cinema set up?

A: YES, Micro, A'Diva and Dué speakers can be run together. All three products are rated at 8 Ohm and use a version of the same 3" driver, they therefore integrate very well indeed.

Q: What is the lowest rated power amplifier I can use with the Nucleus Micro and Dué?

A: The Micro uses our patented "S2 technology". S2 dramatically increases the output of the system. As an 8 Ohm load with high efficiency the Micro will play at normal levels on amplifiers rated as low as 5 watts per channel. Most amplifiers/receivers will have at least 40 watts per channel and therefore enough power to drive the Nucleus Micro.

Q: Will the Nucleus Micro, A'Diva and Dué loudspeakers work with my current equipment?

A: We have designed our speakers to work with just about anything you might already own or are considering purchasing. They have been engineered to seamlessly integrate with almost any brand of audio component on the market.

Q: Can I use my existing cable with the Micro?

A: Many people tell us that their room is already wired in-wall etc. You can of course use any wire with the Micro system. If the run is longer than 25 feet you should use a 16 gauge wire. Less than 25 feet and you can use 18 gauge. Basically, if you set up the system and it sounds good to you, stop worrying and enjoy the music.

Q: How do you get so much sound out of such a tiny speaker as the Nucleus Micro?

A: The Micro and subwoofer both utilise our proprietary and patented "S2 technology". S2 is a way of de-coupling the backsides of the drivers from the air inside the spheres. This allows them to react more quickly to steep transients. It is this increase in efficiency which allows the Micro to be an easy to drive 8 Ohm load. It also gains an additional two full octaves of low frequency extension for any given cabinet size. The satellite thus covers the entire vocal range without a crossover.

Q: What is the importance of not having a crossover in the Nucleus Micro?

A: There is no such thing as a good crossover. All crossovers introduce time and phase distortions that degrade the original signal. By using one single driver to cover the entire range above the THX specification (where your receiver crosses over to the small enclosure setting) the Micro can deliver true audiophile quality sound. This means a very high degree of transparency, tonal accuracy and most importantly a musical experience. Eliminating the crossover also helps to reduce the fatigue that many small satellites tend to cause with extended listening. The most important specifications are not even measured - speed and transparency. These are the details that make a speaker musical and lifelike. Due to the simplicity of our design, the Micro is one of the fastest, most dynamic and transparent speakers at any price and certainly in its class.

Q: Why a sphere?

A: We do not use spherical cabinets because we are trying to make a design statement. Our products are a pure example of form following function. We use a sphere because it solves all of the major problems inherent in box designs.

** A sphere has no internal standing waves where bass output and efficiency are lost.

** A sphere has no external baffle diffraction to smear the signal. This allows our speakers to deliver the most open, transparent soundstage possible. Say goodbye to flat left to right placement of instruments and vocals. The Micro, A'Diva and Dué will deliver accurate recreations of the original recording stage. Placement of instruments is readily discernible up, down, front to back and way outside the actual placement of the speakers within the room. Of course, special effects in movies will take on an entirely new dimension. The added details will convince you that you are one step closer to being there.

** A sphere is the strongest, lightest cabinet possible and has long been known to be the optimal enclosure for a driver. The most important design factors for speaker cabinets are structural rigidity and lack of resonance. Box designs attempt to make up for lack of rigidity by adding mass. Mass simply stores energy which is then released to the environment as harmonics and ringing that are out of time and out of phase with the music, that old familiar "box sound".

Q: How large a room can the Micro stereo system support?

A: Ideally the Micro is suited to rooms of around 16 x 18 feet and smaller. The addition of a powered sub will greatly increase usable room dimensions.

Q: Can I purchase the satellites without the subwoofer?

A: Yes, your dealer will sell them individually or in any quantities you would like.
