A good sound system is the lifeblood of a good gaming or a home theatre system. A good sound system is made of three components; loudness, clarity of sound and fidelity. A good sound system need not be a large, intricate setup. The Sony SRS-XB40 is one such one-box, ultra-portable speaker which packs a powerful punch in an extremely compact form factor. Sony encourages you to create your own nightclub with this speaker’s powerful bass and flashing LED lights.

It also features an ‘Extra Bass’ button which boosts the bass performance with Dual Passive Radiators which work together with two full-range speakers to enhance low-end tones. The Sony SRS-XB40 is available at a price of Rs. 13,940/- in online stores. Let us take a closer look at this speaker system through this review.


The Sony SRS-XB40 is a super-compact, single-box speaker system. It is a rare form-factor which packs in two tweeters and a subwoofer in a single shell. It is portable and weighs in at 1500gms. The front of the speaker is all grill. This grill is surrounded by a light strip which is lit by LEDs. These LEDs can be controlled and can be synced to the beats of music. The light strip appears milky white when it is switched off.

The Sony SRS-XB40 has a landscape orientation by default. There are two flashing strobes packed behind the grill on either end of the speaker. The entire body is finished in matte black. The top and the bottom of this speaker are plain, whereas the sides are textured. The two tweeters are placed at the edges of the speaker and are silver in appearance, which provides a nice contrast to the black grill. The fit and finish of this speaker are excellent, as expected from Sony.
