Helvia’s Estro Bass series is designed for those seeking a compact, lightweight, and easy-to-use passive subwoofer, without compromising on quality and durability.
The 12’’, 15’’, and 18’’ models are built to deliver reliable performance in both fixed installations and live events, differing mainly in woofer size, power, and sound pressure, to suit a variety of audio needs.

ESTRO BASS 12P features a custom 12-inch woofer with a 3" voice coil, capable of delivering a maximum sound pressure of 124 dB and a program power of 1000W. Its multi-ply cabinet is finished with scratch-resistant paint and includes a 1.5 mm steel grille and acoustic foam to protect the driver.
It offers a wide and well-controlled frequency response, with 94 dB sensitivity and a range from 40 Hz to 1 kHz. Weighing 23.5 kg and measuring approximately 42 x 50 x 47.5 cm, it is easily portable thanks to two recessed handles, one on each side. An M20 threaded socket on top allows for an optional pole mount, and connections are made via professional Speakon connectors.
ESTRO BASS 15P, on the other hand, delivers even more power with its custom 15-inch woofer and 4" voice coil, reaching a maximum sound pressure of 127 dB and a program power of 1200W. It also features a sturdy plywood housing with scratch-resistant finish, steel grille, and protective foam.
Its frequency response goes even deeper, ranging from 35 Hz to 1 kHz, with a sensitivity of 96 dB. Dimensions are larger at 46 x 61 x 56.5 cm, and the weight is 32.5 kg. Despite this, it remains practical with recessed handles and mounting points for four 100 mm wheels at the rear, facilitating transport and storage. Like the 12P, it includes an M20 socket on top for optional pole use, with Speakon connectors for wiring.
ESTRO BASS 18P is the most powerful model in the range. Equipped with a custom 18-inch woofer, it delivers a maximum sound pressure of 130 dB and a program power of 1600W. Despite its compact and manageable design, the 18P stands out for its even deeper and fuller sonic impact—ideal for larger live applications or high-efficiency PA systems.
The cabinet is made of rugged multi-ply wood with a scratch-resistant finish and includes a metal grille and acoustic foam for driver protection. It features four recessed square handles (two per side) for easy lifting in both vertical and horizontal orientations.
The top includes an M20 threaded socket for pole mounts like the Soundsation SUBEST100-BK or SUBST100-M20 models, and rear mounting points for four 100 mm wheels simplify transport and storage.
All models use a front bass-reflex configuration to ensure deep, controlled low frequencies, and they share a sleek, functional design meant to integrate seamlessly into any professional setting.
Ultimately, the choice between the ESTRO BASS 12P, 15P, and 18P depends on the required level of sound pressure and power:
- the 12P is ideal for those seeking compactness and easy handling,
- the 15P strikes the perfect balance between performance and manageability,
- while the 18P is the ultimate solution for those who need even more powerful and deep bass response, without sacrificing practicality thanks to its four handles and wheel-ready design.
All represent reliable, high-quality solutions that do exactly what a subwoofer should do: deliver deep, tight bass and, above all, stand the test of time.
ESTRO BASS, like many Helvia products, is built to last and withstand the rigors of everyday use in the most varied jobs.
