Up 4O is a discreet 4” ceiling speaker delivering consistent coverage and crisp, clear sound to a wide range of cost conscious, commercial environments from hotels and concourses to retail outlets, bars and restaurants.
Up 4O is supplied without a back can for ceilings with a minimum cavity depth, while an integral fixing system is included to achieve a simple and clean installation. The steel perforated grille is finished in neutral white.
With the addition of the Grille 1 accessory, Up 4O can be easily enhanced with a bezel-less grille appearance and is available in both black and white, helping to blend into any architectural environment.
Up 4O features a 4” (105mm) driver which is ideal for both music and speech reproduction. A 130° conical coverage pattern ensures the system is delivering sound where it needs to go.
Each Up 4O has been specifically designed to run on 70 or 100 volt line systems via a series of transformer taps.
A SmartAmp or powered Zone will provide amplification, optimal sound performance and loudspeaker protection via onboard presets. When combined with Zone and WebApp, system set up and end user control is simple and intuitive, and can be further augmented by ZonePad wall controllers.

Optimal Audio Up 4O Ceiling Speaker FAQs
The Up 4O is a cost-effective, open-backed ceiling speaker designed for background music and speech in various commercial environments where aesthetics and affordability are key considerations. Some common applications include:
- Retail stores: Background music to enhance the shopping experience.
- Offices: Background music and announcements in common areas or break rooms.
- Hotels and hospitality: Background music and announcements in lobbies, hallways, or common areas.
- Restaurants and bars (with background music needs): Up 4O might be suitable for areas with minimal ambient noise where clear audio is less critical.
Important Note: Due to its open-back design, Up 4O requires a ceiling with sufficient cavity depth to accommodate the speaker without obstruction.
There are numerous features and benefits:
Full-range sound: Delivers clear and balanced audio for music and speech applications with a 4-inch driver.
- Discreet design: The compact size and neutral white finish allow for easy integration into ceilings with minimal visual impact.
- Wide coverage: Offers a 130° conical coverage pattern, ensuring good sound dispersion throughout a small to medium-sized space.
- Passive design: Requires a separate amplifier to function. Optimal Audio offers compatible amplifiers like their Amp series.
- Open-back design: Provides a cost-effective option but requires sufficient ceiling cavity depth for installation.
- Easy installation: Includes an integral fixing system for simple and secure mounting in compatible ceilings.

The Up 4O is a passive speaker, so it requires a separate amplifier to function. Optimal Audio offers compatible amplifiers like their Smartamp series with appropriate power output to drive the Up 4O speakers effectively. When choosing an amplifier, consider the number of Up 4O speakers you plan to connect and the desired listening volume in your space.
