Visaton KT 100V 10cm Woofer 4Ω, 25W, 32-9500 Hz, 80 dB

Looking for that little bit of extra body for your arcade cabinet's sound, without taking up too much space? This compact 10 cm (4") woofer delivers excellent bass performance for its size. Thanks to the low resonant frequency, it adds just that extra dimension to the soundtracks and effects of your favorite retro games.

Key Features:

• Compact & Focused: The elastic rubber surround and deep magnet allow for extended cone excursion, resulting in a fuller sound.

• Clean Reproduction: Smart engineering, including a pole core vent and rear air gap ventilation, prevents unwanted noise even at higher volumes.

• Easy Installation: The straightforward basket design ensures flexible and quick mounting.

💡 Builder's tip for the best result: Do not mount this woofer loosely inside the cabinet, but place it in a small, sealed enclosure. A compact, sealed volume of 2.5 to 3 liters is perfect. This prevents acoustic cancellation (loss of bass) and ensures a surprisingly tight and punchy response.
