Can this be done in Vietnam, or do I have to buy imported marine speakers?+
It can be done here. Tony Lab Audio carries out the upgrade in Vietnam on the professional speakers you already use — there is no need to switch to imported marine speakers or to send your equipment abroad.
How are the cost and the time worked out?+
By the model, quantity, size, condition and the actual scope of treatment — a pair of speakers is very different from a system of several dozen spread across a site. Send us the quantity, the models and photos of where they are mounted; Tony Lab Audio makes a preliminary assessment, then surveys the site and gives you one quote with an expected schedule and a phasing plan, so each area loses its music for the shortest possible time.
Is the upgrade covered by a warranty?+
Yes. The warranty scope depends on the condition of the speakers when we take them in — equipment in original condition and equipment that has already deteriorated cannot carry the same terms. That is why Tony Lab Audio records the condition at the inspection stage, and the warranty terms in the contract follow that record.
Is the work done on site, or do the speakers have to go away?+
Either, depending on the quantity, the mounting positions and the site conditions. On site, we work one cluster at a time so the other areas keep their music; in the workshop, we treat them in batches and bring them back to reinstall in one go.
Can speakers from any brand be upgraded?+
It depends on the model, its construction, its condition and access to the parts that need treatment. Tony Lab Audio inspects first and only then confirms the scope; we never assume every speaker is suitable for the upgrade.
Can speakers that are already faulty, damp or rusty be upgraded?+
The extent of the damage has to be assessed first, because protection is no substitute for fixing internal damage. When a speaker is both faulty and in the wrong environment, Tony Lab Audio repairs it first and then upgrades it on a stable base — one removal and reinstallation for both jobs, and one shared record.
Should brand-new speakers be upgraded before installation?+
For coastal or outdoor positions, yes. Upgrading equipment in original condition gives the best result, avoids the repairs that deteriorated speakers need first, and needs only one installation instead of taking them down again after they are hung.
Does the upgrade change the sound?+
Anything added to a speaker can affect how sound passes through it. That is why Tony Lab Audio chooses the approach for each model, treats the acoustically sensitive zones with care and listens to the system again after completion — we never assume the sound stays the same in every case.
After the upgrade, can the speakers stand in direct rain or be submerged?+
This service is not for submersion and does not by itself create an IP55, IP65 or any other IP Rating, or Marine Certified status. The level of exposure to rain and splashing water, and any shelter needed, is set for each plan and stated clearly at handover.
