Up 4 is a discreet, two-way 4” ceiling speaker delivering consistent coverage and full frequency sound to a wide range of cost conscious, commercial environments from hotels and concourses to retail outlets, bars and restaurants.
An integral fixing system is included to achieve a simple and clean installation. Up 4 has a steel backcan and perforated steel grille and is finished in neutral white.
The Pendant 1 and Grille 1 accessories offer further flexibility in installation and applications, allowing you to either elegantly suspend Up 4 speakers as stylish pendants or achieve a sleek, bezel-less grille appearance. These accessories are available in both black and white, helping to blend into any architectural environment.
Up 4 features a 4” (105mm) low frequency driver paired with a 0.7” (20mm) silk dome tweeter. It is suitable for both high quality speech and music reproduction. A conical 120° coverage pattern delivers consistent sound where it needs to go.
Each Up 4 can be run on a series of 70 or 100 Volt taps or at low impedance. Tap selection is via a rotary switch behind the removable grille.
A SmartAmp or powered Zone will provide amplification, optimal sound performance and loudspeaker protection via presets. When coupled with a Zone and WebApp, system set up and end user control is easy, and can be further supplemented by ZonePad wall controllers.

Optimal Audio Up 4 Ceiling Speaker FAQs
The Up 4 is a versatile, full-range ceiling speaker designed for background music and speech in various commercial environments. It offers a good balance between performance and cost-effectiveness. Here are some common applications:
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 4 can be suitable for areas with moderate ambient noise where clear audio is important.
- Classrooms: Up 4 might be suitable for small to medium-sized classrooms depending on the desired volume and ambient noise levels.
There are notable features and benefits:
- Full-range sound: Delivers clear and balanced audio for music and speech applications with a 4-inch low-frequency driver and a 0.7-inch silk dome tweeter.
- Discreet design: The compact size and neutral white finish allow for easy integration into ceilings with minimal visual impact.
- Wide coverage: Offers a 120° 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.
- Enclosed backcan: Provides better sound isolation and allows for more flexibility in ceiling cavity depth compared to open-backed designs.
- Easy installation: Includes an integral fixing system for simple and secure mounting in compatible ceilings.
- Built-in transformer: The Up 4 features a built-in transformer, allowing connection to constant voltage distributed speaker systems (70V or 100V) commonly used in commercial applications. This eliminates the need for individual amplifiers at each speaker location.
Here’s a table summarising the key differences between Up 4, Up 3, and Up 6 to help you choose the best model:
Feature | Up 4 | Up 3 | Up 6 |
Driver size | 4 inch | 3 inch | 6 inch |
SPL | 102dB (cont) 105dB (peak) | 97db (cont) 100dB (peak) | 108dB (cont) 111dB (peak) |
70/100V line operation | Yes | Yes | Yes |
Low impedance operation | Yes | Yes | Yes |
Applications | Wider range | Small/medium | Medium/large |
Sound coverage | 120° conical | 130° conical | 110° conical |
The Up 4 is a passive speaker and requires a separate amplifier to function. Since it has a built-in transformer, it can be used with 70V/100V distributed speaker systems or with a low impedance amplifier depending on your setup. Optimal Audio offers compatible amplifiers like their Smartamp series with appropriate power output to drive the Up 4 speakers effectively. When choosing an amplifier, consider the number of Up 4 speakers you plan to connect, the type of speaker connection (70V/100V or low impedance), and the desired listening volume in your space.
