Ever wondered why speakers, amplifiers, projectors etc. come with a slightly heftier price tag in India compared to their overseas counterparts? Well, part of the answer lies in our country's Goods & Services Tax (GST).

But here's the kicker: Don't let that GST input slip through your fingers! Especially when some of the products we supply carry a GST rate of 18% and 28%.

At AVStore, we provide you with a GST compliant invoice for every purchase.

The AO-620 is the perfect speaker to complement to your outdoor activities. Whether you’re enjoying a backyard picnic, get-together or even listening to the game, the AO-620 provides stellar audio fidelity given its slender size. A must-have for those who value their outdoor lifestyle, the AO-620 is an investment you’ll never regret. The AO-620 can easily be installed in corners or under eaves to coordinate with virtually any house décor.


The cabinet of the AO-620 outdoor speaker is constructed of impact resistant fortified ABS which is sealed to provide resistance from the natural elements of the weather.

The angled cabinet back is designed for easy placement into a corner. All hardware parts are made from brass, aluminium or stainless steel and the binding posts are plastic to avoid corrosion.

For high frequencies, a 1-inch mylar dome tweeter is used. This tweeter uses Ferro FluidTM liquid cooling to allow greater power handling. A long throw 51⁄4 or 61⁄2-inch poly graphite woofer with a butyl rubber surround is used for midrange and bass reproduction. Steep acoustic slope crossovers are used to integrate drivers.

The use of steep crossover slopes allows high power handling, minimises driver interaction anomalies, and maximises the clarity with which each driver is able to produce its respective frequency band.

The bracket allows the speaker to be hung either horizontally or vertically, and can be mounted several different ways and swivels for optimum placement.


  • A - The AO-620 speaker can be mounted either horizontally or vertically. Hold the bracket against the mounting surface, so you can mark the locations of the mounting holes, and the wire hole (see the Parts Guide on page 1).
  • B - Drill corresponding pilot holes for the included mounting screws or nails (not included), and a hole large enough for speaker wire to pass through.
  • C - Pull speaker wire through the hole and through the bracket, aligning the bracket with the holes.
  • D - Use hardware to attach the bracket to the mounting surface.
  • E - Use the bracket knobs to attach the speaker to the bracket, being careful to not tighten the knobs; this will allow the speaker to be angled slightly so the rear binding posts are accessible.
  • F - Connect one wire to the black terminal and one to the red terminal, paying close attention to the markings on the wires for proper polarity. Each speaker must be connected to the amplifier in the same way.
  • G - Adjust the speaker for desired position and tighten the bracket knobs.


The distance from the listening position to each speaker should be close to the distance that separates the two main speakers. Angling the speakers inward towards the listening position may give a more spacious and realistic sound stage.

Placing the speakers in a corner or under an eave will provide reinforcement for the bass frequencies, resulting in higher bass output. Placing the speakers away from any corners or walls will provide the least amount of reinforcement, resulting in lower bass output.


We recommend an amplifier with an output power rating of 25-100 watts per channel. This will help to protect the speaker from being under or over driven, which could cause permanent damage.

When listening to the speakers outdoors, keep in mind that there are very few walls to reinforce the sound. Therefore, be careful not to drive the speakers beyond what they are capable when trying to obtain a desired volume level. You will be able to determine audibly when the speaker is being over driven by the “break-up” or distortion that is coming from the speaker.
