An independent team designing sound and space with equal precision.
Watteffects is a Kolkata-based audio visual and automation consultancy — built on detailed design drawings, honest documentation, and a promise that you won't need to be on site until the day we hand your home over.
Our Profile
Watteffects has an independent team of experienced audio visual and automation consultants offering practical solutions for sound clarity and noise control.
Our strength lies in detailed video design plan drawings and audio design documentation, which helps us estimate costs accurately and deliver every project within the pre-decided timeline.
Once we take over a project, we make sure our client doesn't need to get involved on site again until the day of the final demonstration — which is what makes the experience genuinely hassle-free.
Independent Consultancy
Unbiased AV and acoustic advice, built around your space rather than a single brand.
Design-First Approach
Every project starts with detailed drawings and documentation, so costs and timelines are fixed early.
Hassle-Free Delivery
We manage the site end to end — you step back in only for the final demonstration.
Two demo spaces, one goal — let you hear and see it before you own it.
We're spread across 5,000 sq ft on Southern Avenue in a concept “Demo High-End Flat,” built to show exactly how your own home could look and sound after installation and automation.

We also run our own Authorised Service Centre, so support for everything we install stays in-house.
