The Dayton Audio Classic B40 bookshelf speakers are passive speakers featuring a 10.2cm woofer and a 2.54cm silk dome tweeter, able to support up to 30W RMS power at a 6-ohm load (60W max.). They have the advantage of being able to be placed anywhere and are ideal for near-field listening. The Classic B40s benefit from a sealed enclosure that reduces distortion in the low frequencies. Their sensitivity of 82dB and frequency response of 75Hz to 20kHz make them excellent speakers, offered at a more than reasonable price. On the rear panel, there is a gold-plated terminal block and a very practical wall-mount bracket for easy integration into any space.
The key features of the Dayton Audio Classic B40 speakers:

The robust 10.2cm woofer delivers deep bass.

The tweeter delivers detailed high frequencies for a smooth and clear reproduction of vocals.

The sealed-box suspension design significantly reduces distortion at low frequencies.
The Classics B40 feature a delightful vintage look, allowing them to blend seamlessly into a complete audio system.


The Dayton Audio B40 features gold-plated terminals for improved conductivity and resistance to corrosion and oxidation. In addition, a wall-mount bracket makes it easy to integrate them into a home cinema setup, allowing them to be installed on either side of a screen quickly and easily. Finally, two speaker cables are included so that the speakers are ready for immediate use.
