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 ATC SCM40 is part of a rare group of loudspeakers that use a dome midrange driver rather than the usual cone type driver. This setup means excellent integration between the midrange driver and the similarly shaped tweeter keeping everything neatly together and revealing insights into recordings other speakers can only dream of. 

The larger volume of SCM40 means an altogether deeper bass response from this sealed cabinet whilst retaining the snap of its smaller siblings. This speaker however will require the amplifier to step up to the mark as they are not the most efficient floorstander and will benefit from a more powerful design.

The SCM40 exhibits an even load for amplifiers to drive albeit a larger higher quality amplifier is suggested of somewhere between 75 to 300 watts. The SCM40 in common with others in the range is designed for optimum performance without the grille but are supplied with perforated metal items in dark grey to offer driver protection if you wish to use them.

No Substitute for In-House Engineering and Manufacturing

Found in many of the world's finest recording studios and soundstages, and used by dozens of the most acclaimed producers and engineers in the music and film industries, ATC loudspeakers claim an unparalleled reputation. Focused on applying supreme engineering to proven audio principles, the tradition-minded British company produces English-made speakers revered for their revealing nature, astonishing clarity, and exceptional balance. Tested and assembled in-house, its famous drivers and tweeters are exclusive to ATC – you won't find them on any other brand. And unlike most manufacturers, ATC still constructs midrange domes to supply breathtaking coherence. The rest of the rationale follows: If ATC is good enough for studio pros such as the late Doug Sax and superstar artists like the Rolling Stones, they're good enough for you.
