The H-PAS PowerBar 235 is a 43 long self powered soundbar that delivers multi channel high-fidelity sound for your home entertainment system. It features Atlantic’s H-PAS bass system, which produces deep, distortion-free bass without the need for a subwoofer!H-PAS (Hybrid Pressure Acceleration System) is a unique, patented bass system that combines the best of four bass technologies: acoustic suspension, inverse horn, bass reflex, and transmission line. By cascading the four technologies onto one another in a precise, mathematically-determined formula, H-PAS achieves extremely deep bass response from small woofers in a compact enclosure, with no requirements for a high powered amplifier. Hence no subwoofer needed! It is a perfect standalone solution that represents a quantum leap in both acoustic technology and user convenience! Perfect for an easy home theater in a master bedroom or any room that you want dominated by additional speakers.Using just two 4 woofers, the H-PAS PowerBar 235 reaches down to a solid 47Hz at very high theater-like SPLs for an absolutely convincing and totally satisfying sonic experience. Because of its extended frequency response and dynamics, the H-PAS PowerBar 235 is the first soundbar where the subwoofer is truly optional. Its high-current, equalized 125-watt amplifier and massive finned heat sink are proof of the power that lurks beneath it’s glossy surface. The SB8 has a low-end extension of 32 Hz (-3 dB) and its solid, muscular sound surprises and delights listeners every time.The H-PAS Powerbar 235 is powered by an on-board amplifier that supplies 80 total watts RMS.
