Frequently asked questions
Can you work with my existing TV and receiver?
Absolutely. We build around quality gear you already own and fill the gaps.
Do you handle in-wall and in-ceiling speakers?
Yes — discreet in-wall and in-ceiling speakers are one of our most-requested upgrades.
How long does a theater install take?
A media room is often 2–4 days; a dedicated theater with acoustic treatment runs longer. We give a firm schedule in the proposal.
