Standard Hookup

Bi-Wiring & Bi-Amping

If you decide to bi-wire or bi-amp, you must remove the jumpers between the terminal posts. Failure to do this could result in damage to your amplifier and loud- speakers. The binding post caps must be completely removed to remove the jumpers, which use ring terminals. There are color coded collars so you can identify which

is (+) or (–) after you remove the caps.

Bi-Wiring (see Figure 1)

Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low and high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers, the lower set of binding posts are for the low frequency drivers): after removing the jumpers, connect one set of speaker wires to the upper terminals on each speaker and one set of wires

to the lower terminals. Connect the other ends of both wire sets to the same amplifier outputs.

Bi-Amping (see Figure 2)

Bi-amping allows you to use separate amplifiers for the high and low frequency sections of your loudspeaker for greater dynamic range and lower distortion. We recommend that your separate amplifiers have identical gain to preserve the speaker’s voicing balance. After removing the jumpers, connect the speaker wires from the high frequency amplifier outputs to the upper set of terminal posts on each speaker. Follow the same procedure for connecting the low frequency amplifier outputs to the lower set of terminals. Remember to maintain correct wiring polarity (+ to +, – to –) in all connections.

Wire Recommendations

These recommendations are for all connections from the amplifier/receiver to each speaker:

LSiM specifications

Polk Audio has long been synonymous with quality sound reproduction, and the LSiM series stands as a testament to this reputation. Known for their innovative engineering and exceptional sound quality, the LSiM speakers are designed to cater to audiophiles and casual listeners alike, delivering a rich and dynamic audio experience.

One of the main features of the LSiM series is its use of advanced materials and technologies, which include the use of Dynamic Balance drivers. This unique driver technology enables the speakers to minimize distortion while maximizing transparency and sound detail. The LSiM speakers are equipped with a 1-inch ring radiator tweeter and a specially designed 5.25-inch midrange driver. This combination ensures that high frequencies are crisp and clear, while midrange sounds are natural and warm, providing a well-balanced audio performance across genres.

Another standout characteristic of the LSiM series is its construction quality. The cabinets are meticulously engineered using high-quality materials that help reduce resonance and ensure durability. The curved design not only contributes to aesthetics but also aids in the dispersion of sound, resulting in a wider sweet spot for listeners. Each speaker comes with a rear-firing bass port that enhances low-frequency response, allowing for deeper bass without compromising clarity.

Polk Audio has also integrated its patented Power Port technology in the LSiM speakers. This technology effectively extends the low-end frequency response while eliminating turbulence and distortion caused by traditional port designs. The result is an impressive bass output that remains tight and controlled, perfect for both music and home theater applications.

The LSiM series offers versatility in terms of speaker configuration. Available in various models, including floor-standing, bookshelf, and center channel options, these speakers can be mixed and matched to create a custom sound system that fits any space. Their aesthetic appeal is further enhanced by a modern and elegant finish, making them a stylish addition to any room.

In conclusion, the Polk Audio LSiM series combines advanced technologies with superior craftsmanship to deliver an unparalleled listening experience. Whether for a high-end home theater setup or everyday music enjoyment, the LSiM speakers promise to provide an immersive soundstage and exceptional audio fidelity, making them a remarkable choice for anyone seeking quality sound in their home.
