Challenger CSB-V15
Hemmabio nr 12 2020
Sensitive home theater subwoofer
“With a solid 15-inch driver and a cabinet that feels relatively compact despite its size, the Dynavoice Challenger CSB-V15 fits just as well in a living room as in a dedicated theater room.”
“Regardless of whether you have tall floorstanders or small bookshelf speakers, at least one subwoofer is needed for the best possible sound. In home theater, it is especially important since the .1 channel contains all low-frequency effects. Dynavoice has equipped the CSB-V15 with a dedicated LFE input for home theater use, stereo input for music, and high-level inputs for connection in parallel with speakers. It also has a 12-volt trigger input and an unfiltered low-level output for an additional subwoofer. Controls on the back include volume, continuously adjustable phase, and crossover frequency from 35 to 150 Hz. There is also a single-band EQ that can boost or cut 3 dB around 63 Hz.”
“The cabinet is built from 19 mm MDF with a double-thick baffle and internal bracing, giving a stable construction. The driver has an aluminum cone and is powered by a Class AB amplifier. Damping inside the cabinet is minimal, with a single layer of fiber filling on most walls. The design feels well thought-out, with a clear focus on achieving the best possible balance between price and performance at around 9,000 kronor.”
Sound quality
“The LFE channel delivers with great authority. Even at higher crossover frequencies around 70 Hz, the CSB-V15 maintains control and doesn’t become easy to localize in the room. The subwoofer handles overtones well, allowing for unusually high crossover settings without losing integration. It can be described as sensitive, responsive, and easy to fit into any system, with deep, confident bass and good dynamics. The sound is smooth and controlled, equally well-suited for music and movies.”
Conclusion
“You can’t have everything, and with the Dynavoice CSB-V15 that means a -3 dB point around 30 Hz, about 10 Hz higher than more expensive options. In most rooms, though, this is not an issue, as placement can provide solid reinforcement in the lowest range. For the price, CSB-V15 offers a very well-balanced mix of power, finesse, and precision. For anyone wanting strong yet refined bass under 10,000 kronor, this Dynavoice subwoofer deserves serious consideration.”
