Where can I hear the Nucleus Micro, A'Diva, Strada and Reference 3.5?
Please check our Dealer Search page.

Can I mix Micro, Micro Ti, A'Diva, A'diva Ti and Strada speakers
as part of a Home Cinema set up?

Yes, all speakers can be run together as they are all rated at 8 ohms and integrate very well indeed. A Strada can be used for example as a centre channel loudspeaker with a pair of A'Diva or A'Diva Ti as the left and right channels and a pair of Nuclues Micro or Micro Ti for the rear or surround channels. Your dealer will be able to advise on the best combination for your requirement and budget.

What is the lowest rated power amplifier I can use
with the Nucleus Micro, Micro Ti, A'Diva, A'Diva Ti and Strada?

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 plenty of power to drive the Nucleus Micro.

Will the Nucleus Micro, Micro Ti, A'Diva, A'Diva Ti and Strada speakers
work with my current equipment?

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.

Can I use my existing cable with the Micro and Micro Ti?
Many people tell us that their room is already wired in-wall etc. You can of course use any wire with the Micro and Micro Ti 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.

How do you get so much sound out of tiny speakers?
The Micro, Micro Ti 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/Micro Ti 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.

What is the importance of not having a crossover in the Nucleus Micro / Micro Ti?
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 / Micro Ti 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.

Why a sphere?
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.

• Spheres can eliminate 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, Micro Ti, A'Diva, A'Diva Ti and Strada 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".

How large a room can the Micro/Micro Ti stereo system support?
Ideally the Micro/Micro Ti is suited to rooms of around 16 x 18 feet and smaller. The addition of a powered sub will greatly increase usable room dimensions.

Can I purchase the satellites without the subwoofer?
Yes, your dealer will sell them individually or in any quantity you like.

Our responsibilities as an EEE producer

With effect from July 2008, the UK's Waste Electrical and Electronic Equipment (WEEE) Regulations require that all producers of electrical equipment are obliged to pay for recycling of household electrical goods, where previously this bill was met by councils, or items were not recycled at all. These regulations also require that all retailers both actively assist in delivering a UK wide WEEE collection infrastructure and encourage the participation of consumers in recycling electronic equipment.

Electronic waste is one of the fastest growing waste streams and much of it can be recycled and resources recovered to make new consumer goods. To remind consumers that goods should be recycled, all electrical items sold now carry the 'crossed out wheeled bin' symbol.

Anthony Gallo has contributed towards a national fund which is used to help local councils to further develop their waste electronics collection facilities, which will in turn allow producers of this equipment to meet their obligations.

Not all council sites are suitable to collect all types of waste electrical goods but to find out your nearest participating site (including other collection facilities that may not be operated by the council) and for advice on all aspects of recycling at home, please visit

Where can I find out more about recycling WEEE and
other household waste?

Recycling in the home is easy when you know how. On there are lots of handy hints to help you reduce waste, recycle rubbish and reuse household items you may have otherwise thrown away.

Our responsibilities as an EEE distributor

In order to partially meet our obligations as a distributor as defined in the UK Waste Electrical and Electronic Equipment (WEEE) Regulations (SI 2006 No. 3289 - 11 December 2006) (referred to hereafter as "the WEEE Regulations"), we have opted to become a full member of the Distributor Take back Scheme (DTS).

Membership of the DTS is defined in regulations 35 of the WEEE Regulations and delivers exemption from the requirements of regulation 31 (to "ensure that WEEE from private households can be returned to him free of charge and on a one-to-one basis") and regulation 34 (1) (maintenance of records).

As a member of the DTS, we have made a financial contribution toward the development of the network of Designated Collection Facilities (DCF's) instead of offering in-store take back of WEEE. This financial contribution is described in paragraphs 83 to 88 of the UK WEEE guidance, and has been used to improve the WEEE collection facilities located at Local Authority Civic Amenity sites.

In addition, through our support of the national recycling website,, we will also meet our obligations under regulation 33 to make information available to users of EEE in private households on:

  1. The requirement on each Member State under Article 2 of the Directive to minimise the disposal of WEEE as unsorted municipal waste and to achieve a high level of collection of WEEE for treatment, recovery and environmentally sound disposal.

  2. The collection and take back systems available to you the consumer.

  3. Your role as a consumer in contributing to the reuse, recycling and other forms of recovery of WEEE under these regulations.

  4. The potential effects on the environment and human health as a result of the presence of hazardous substances in EEE.

  5. The meaning of the crossed out wheeled bin symbol.
