Sony has expanded the range of speaker EXTRA BASS with the new models SRS-XB43, SRS-XB33 , and SRS-XB23. All the products are equipped with driver X-Balanced Speaker of new design. The shape of the transducer is not circular, a choice that Sony motivates with the possibility of extending the area of the aperture, increasing the sound pressure, and improving the reproduction of low frequencies. The japanese engineers have also obtained a reduced excursion of the driver and a reduction of distortions

XB43 is the product of higher-end and also the one with the larger sizes. Measuring 325 x 123 x 117 mm with a weight of 2.95 kilograms. Within it are contained the X-Balanced Speaker of a form almost rectangular, that go to create a two-way system with a pair of tweeters and a pair of woofers. For bass reinforcement, are used two passive radiators placed in the sides. The cone and dust cover are made of Mica Reinforced Cellular (MRC), a rigid material, and light can also be chosen for its acoustic properties.

The speaker is certified to IP67 and is therefore resistant to shock, dust and dive into a liquid up to 1 meter deep for 30 minutes. The user can choose to place XB43 in horizontal or vertical. Connectivity Bluetooth 5.0 supports the profiles A2DP, AVRCP, HSP, HFP, SPP, and the codec SBC, AAC , and LDAC. There are also NFC, hands free calling, an audio input jack 3.5 mm and two USB ports, a Type-C for charging and a Type-A to power devices such as smartphones and tablets (5V, 1A). The integrated battery guarantees an autonomy that can reach a maximum of 24 hours of operation.

Among the available functions include the mode , LIVE SOUND, which offers an experience called the “three-dimensional”, capable of spreading the sound over a wider area. Through theapplication Fiestable (iOS and Android) you can adjust the light effects offered by the LED, causing them to pulsate to the rhythm of the music or change color through a smartphone. Party Connect, finally, allows you to connect up to 100 speaker-compatible via Bluetooth, synchronizing music and lights.

XB33 looks similar but more compact dimensions. Measuring 246 x 97 x 106 mm with a weight of 1.1 kg. Inside houses two transducers full range, capable to increase the sound pressure of 30% and to reduce the distortion of 25% (compared to the previous SRS-XB32). There are always the passive radiators to the side and all of the features described for the model XB43, including the double positioning vertical or horizontal. Also the battery life is the same.

On the lowest rung is positioned XB23, a product with a cylindrical shape with a diameter of 76 millimeters and a height of 218 mm. The weight drops to 580 grams. The speaker is equipped with a strap useful for hanging curtains, trees or in other situations. The sound is distributed through two transducers full-range flanked by passive radiators on the side. On XB23 are missing the function LIVE SOUND, the USB Type-A, NFC, and the application Fiestable. The autonomy reaches 12 hours of playback in STAMINA mode.

All of the speakers will be available from August in the following colors:

  • SRS-XB43: blue version and black
  • SRS-XB33: black, blue, red and taupe
  • SRS-XB23: black, blue, red, taupe and green
