Eight Singapore-based installers that handle high-end audio for landed homes, condos, HDB resale flats, and luxury cars — covering the exact showrooms at The Adelphi (1 Coleman Street), the common in-wall cable constraints, and the calibration software they run (REW, Dirac Live, Trinnov Altitude, Mosconi DSP).
1. AV One
One of the anchor tenants at The Adelphi. AV One works mostly on condos and landed home theatres, running full 7.4.4 Dolby Atmos builds with equipment racks in utility rooms. They run fibre-optic HDMI 2.1 in concealed conduit before the false ceiling goes up, and they use REW for post-install room correction. For residential jobs in Bukit Timah, they routinely fit Bowers & Wilkins 800 Series in-wall units with dedicated amplifier rooms — not just a receiver stuck in a TV console.
2. Sound Concepts
Sound Concepts focuses on architectural audio: invisible in-wall speakers, hidden subs, and acoustic panels that match the interior joinery. Their typical contract is a GCB (Good Class Bungalow) with either Lutron or KNX lighting control, plus a dedicated network rack with fibre backbone. They are one of the few shops that will bring in a CEDIA-trained calibration engineer for both audio and video. Lead time for a full install is around 4 to 6 weeks after the site survey.
3. KEC Sound
Also based in The Adelphi. KEC Sound is strong on two-channel Hi-Fi but handles full home theatre installs for interior designers. They carry brands like DALI, Rotel, and AURALiC, and they do proper cable dressing for resale condos where you cannot cut new chases into concrete walls. Their installers use surface-mounted trunking that matches the wall finish, and they are comfortable integrating with existing Control4 or Crestron lighting panels the owner already has.
4. Integrate Systems
Integrate Systems does both residential and commercial high-end audio. Their lane: boardroom audio-video and house of worship sound systems in the West and North areas of Singapore. They handle acoustic modelling for large rooms using their own microphone sweeps, and they specify line-array speakers for church halls. They also run structured cabling audits first — if the existing Cat6 network is unmanaged, they will fix the network before putting in a streaming-based Hi-Fi stack.
5. Alpha Audio
Alpha Audio is a specialist in video-plus-audio matching. Their typical project: a dedicated theatre room with a JVC or Sony projector, a Trinnov Altitude processor, and a 7.4.4 or 9.4.6 speaker layout. They calibrate the room using Dirac Live and can adjust crossover points and delay timings per seat. Their installs often include IR repeater systems and dedicated power line filtering. They are known locally for servicing customers who imported equipment directly — they will install it if the unit is compatible with Singapore’s 230V supply.
6. Hifi Solutions
Hifi Solutions handles mid-to-high-end audio upgrades for resale flats. Their installers have done countless HDB 5-room and executive maisonette jobs. They respect the constraints: no heavy floor-standing speakers on timber-frame floors, in-wall wiring only where permitted, and subwoofer placement that will not trigger noise complaints from the neighbour below. They also specialise in all-in-one streaming systems with NAS setups for high-resolution FLAC libraries, using Roon instead of just Spotify Connect.
7. 2J Audio
For car audio, 2J Audio is the direct opposite of a typical accessory shop. They are certified to install high-end car audio systems in luxury and performance cars: from BMW M and Mercedes-AMG to Porsche. Their work includes custom subwoofer enclosures in the boot, full door damping with butyl-based sheets, and aftermarket DSP processors like Mosconi or Helix to run an active three-way front stage. Their technicians do real-time frequency response measurements inside the vehicle while the engine is idling, and they hide all wiring to factory tolerances — no cable ties on airbags, no splice that voids warranty.
8. The Audiophile
The Audiophile at The Adelphi is the go-to for turntable-based Hi-Fi installations. Their installs cover tonearm alignment, phono stage gain matching, and isolating wall shelves for floors that vibrate. They also set up whole-home audio systems using Sonos for the rest of the family while keeping the primary room pure two-channel analogue. They are particularly good at installation jobs that need minimal visual intrusion — they will route speaker cable through walls and install floor boxes so that you can place speakers away from the wall without visible cabling.

Each installer operates with different site constraints, so the correct provider depends on whether your job is a concrete-walled HDB flat, a condominium unit with drywall partitions, a landed home with a dedicated AV room, or a car boot. The Adelphi cluster covers most of the residential market; for car audio, 2J Audio works out of its own workshop and will travel to your location for the initial measurement.
