BST 270TW - Pair of 2-Way Wall Speakers with Adjustable Bracket and Selector 100V/8Ω
The BST 270TW is presented as a complete and versatile professional audio solution, specifically designed to enhance sound quality in fixed installations of any size. This set includes two wall-mounted speaker units that stand out for their hybrid capability, allowing them to operate in both high-impedance (100V line) systems typical of large venues and low-impedance (8Ω) configurations for more conventional stereo or home environments.
Acoustically, each speaker delivers a high-fidelity experience thanks to its 2-way design. It features a 5.25-inch (13 cm) woofer that reproduces full-bodied and present mid and bass frequencies, complemented by a 1.5-inch tweeter that ensures crystal-clear and defined highs. This combination covers an optimized frequency range (90 Hz – 20 kHz), guaranteeing that both background music and voice announcements are heard with complete clarity and without distortion, even at high volumes.
The BST 270TW was designed for durability and aesthetic integration. Its chassis is made of high-strength ABS , a robust material that protects the internal components, while its metal front grille provides a professional finish and protection against minor impacts. The textured white color and understated design allow these speakers to blend seamlessly with wall and ceiling decor, minimizing their visual impact on well-maintained spaces. Furthermore, its mounting system includes lyre-shaped brackets that facilitate quick and secure installation.
Main features
The engineering behind the BST 270TW is focused on simplifying the installer's work and improving the end-user experience. Its technical features make it a benchmark in its category:
-
2-way audio system: The separation of frequencies between the woofer and the tweeter allows for a much richer and more detailed sound than single-cone speakers.
-
Versatile line transformer: It has an integrated selector (usually accessible behind the grille or on the rear panel) that allows you to choose between different power outputs (30W, 15W, 7.5W) to balance the volume in 100V systems, or to bypass the transformer for direct use at 8Ω.
-
Wide sound dispersion: With a 160° coverage angle, it reduces the number of speakers needed to cover an area, eliminating sound "dead spots".
-
Mounting hardware included: Supplied with sturdy metal brackets that allow you to orient the speaker, directing the sound exactly where the audience is located.
-
Acoustic efficiency: Its design optimizes audio output, achieving remarkable sound pressure for its compact size.
Product benefits
-
Total adaptability to the installation: Whether for a small boutique requiring stereo sound or a large shopping center with hundreds of meters of cabling (100 V), this speaker serves both purposes without the need to purchase different equipment.
-
Discreet architectural integration: Its neutral white finish and smooth lines make it ideal for places where aesthetics are paramount, such as designer restaurants, art galleries, or clinics.
-
Zone volume control: Thanks to selectable power jacks, it is possible to install speakers in noisy areas at 30W and in quiet areas (such as hallways or bathrooms) at 7.5W within the same speaker line.
-
Long service life: The combination of ABS and metal ensures that the equipment withstands the test of time and continuous use in demanding commercial environments.
-
Installation savings: By including the adjustable brackets, the need to purchase additional hardware is eliminated, and their design allows for easy fixing with basic tools.
Use cases
This speaker system is the preferred choice for audiovisual integrators in a wide variety of projects:
-
Hospitality and Catering: Ideal for creating immersive atmospheres in dining rooms, bars and hotel reception areas.
-
Retail: Perfect for clothing stores, supermarkets, and car dealerships that need quality background music and clear announcements.
-
Corporate Environments: Meeting rooms, open-plan offices and rest areas where voice clarity is required.
-
Educational and Religious Centers: Main lecture halls, school corridors or small chapels that need reliable sound reinforcement.
Frequently Asked Questions
-
How do I select the power or 8 Ohm mode?
The speaker has a switch or selector (often located behind the front grille or on the back near the terminals) that allows you to choose between the 100V taps (30W, 15W, 7.5W) or the low impedance position (8Ω). Be sure to configure it before final installation.
-
Can I install these speakers outdoors?
Although its ABS casing is very durable, the BST 270TW model is primarily designed for indoor or covered outdoor areas (such as porches or covered terraces) where it does not receive direct rain or excessive humidity.
-
Do I need a special amplifier?
It depends on the operating mode. If you use them in 100V mode (recommended for connecting multiple units), you need a 100V line PA amplifier. If you use them in 8Ω mode (one or two pairs maximum), you can use a standard stereo amplifier.
-
Can speakers be painted?
Yes, both the ABS casing and the metal grille (if previously removed) can be painted with spray paint suitable for plastics and metals, allowing them to match the exact color of your walls.
