The difference between the bass effects of KA18 and KA28 subwoofers
KA18 single 18" subwoofer
KA18 is a single 18-inch subwoofer designed for Kara line array system, which can extend the system's low-frequency limit to 32Hz. It uses a single 18-inch woofer with a dual bass reflex tuned cabinet to provide high sensitivity, low thermal compression and low distortion. The SB18 has a deep and clean bass effect, which can remain stable even at high sound pressure levels, suitable for small and medium-sized performances, home theaters or KTVs.
KA28 dual 18" subwoofer
KA28 is a high-performance dual 18-inch active subwoofer designed for large events and professional audio systems. It has a lower low-frequency limit (25Hz) and a higher maximum sound pressure level (143dB), which can provide a stronger and deeper bass effect. With an RMS power of up to 3200W, KA28 supports standard and cardioid configurations, suitable for scenes that require high sound pressure levels and stronger bass performance, such as theaters, outdoor performances and large events. The dual 18-inch design and high power make it an excellent choice for large systems, and it is an ideal choice for those who seek the ultimate bass effect.

If you purchase Sinbosen dual 15-inch line array and dual 12-inch line array for large indoor and outdoor performances, such as KA-1 and KA-2, it is not enough to just purchase KA18 for bass. KA18 is a subwoofer. If sufficient bass effect is required, it is recommended to purchase Sinbosen's KA28 dual 18-inch subwoofer.
The cardioid dispersion pattern reduces the reverberant field at low frequencies and provides low frequency reproduction.
The KA28 takes bass performance to a whole new level. Frequency band below 25Hz with excellent low frequency resolution.
