Impedance, With One or Two Subwoofers | Niles Audio PSW800 specs

Impedance

With One or Two Subwoofers

When one or two PSW800 subwoofers are connected to the satellite speakers, the overall system impedance to the amplifier lowers.

System Impedance in Ohms (Ω)

One or Two Subwoofers

	8Ω Sats	4Ω Sats
1 Sub	4Ω	2.6Ω
2 Subs @8Ω each	4Ω	2.6Ω
2 Subs @4Ω each	2.6Ω	2Ω

If the impedance is too low for your ampli- fier, utilize a Niles speaker selector or IM volume control to match the impedance.

VLSA (Four or More Subwoofers)

A VLSA installation lowers the amount of excursion required to achieve a high sound pressure level. Lowering excursion dramatically improves the quality of the sound. VLSA installations are most appro- priate when the listener appreciates detail and bass extension, but must have a con- cealed installation.

Each subwoofer should have its voice coils connected in parallel for full output, therefore the impedance of each is four ohms. Because of this low impedance, a multi-channel amplifier stable to four ohms is the best way to drive more than two subwoofers. Each PSW800 is con- nected to its own channel of the multi- channel amplifier.

Check Your Amplifier’s Specs

Every amplifier has a minimum impedance specification. Check your owner’s manual for the specification for four ohm low impedance drive capability. If there is no

clear indication and your amplifier or receiver has two sets of speaker terminals (typically labeled “A” and “B”) your ampli- fier may be capable of driving a four ohm load. Perform the following test to be sure:

Parallel/Serial Speaker Connection Test

1.Hook up one pair of speakers to the “A” speaker terminals of your amplifier. Leave the “B” terminals unconnected to speakers.

2.Engage both the “A” and the “B”. Listen for sound.

If your amplifier plays sound when “A” and “B” are engaged, it is capable of dri- ving a four ohm speaker load. If your amplifier does not play sound when “A” and “B” are selected, it is only capable of driving an eight ohm speaker load. An eight ohm stable amplifier may only be used with a PSW800 satellite/subwoofer system by installing an impedance magni- fying volume control.

An amplifier stable to four ohms may be connected without impedance matching devices. Parallel connections via the “A” speaker terminals to one or two PSW800 subwoofers (If the voice coils are not in par- allel) and one pair of eight ohm satellite speakers results in a four ohm load.

The “B” speaker terminals cannot be used to power a second pair of speakers any- more. The low impedance drive capability of your amplifier is already utilized by the satellite/subwoofer combination. If you are connecting other speakers in other rooms you must install either a speaker selector or impedance magnifying volume controls.

A few professional/audiophile amplifiers advertise the capability of driving two ohm speaker loads. These amplifiers may be used without impedance matching devices if the rating is quoted as “RMS” or “Continuous” power.

PSW800 specifications

The Niles Audio PSW800 is a powerful subwoofer designed for home audio systems, delivering exceptional performance with an innovative blend of technology and engineering. Known for its deep, rich bass and high-efficiency output, the PSW800 is an ideal choice for audiophiles and casual listeners alike.

At the heart of the PSW800 is a high-quality 8-inch woofer, which utilizes a polypropylene cone that provides durability and reduces distortion. This driver is coupled with a robust magnet structure that enhances its performance, ensuring that the subwoofer can reproduce low frequencies with clarity and impact. With a frequency response range that extends down to 30 Hz, the PSW800 can produce the low-end sounds crucial for a full audio experience, whether it’s the thunderous explosions in an action movie or the intricate bass lines in music tracks.

One standout feature of the PSW800 is its built-in high-current amplifier. This powerful amplifier can deliver up to 200 watts of peak power, providing the necessary force to drive the woofer effectively. The combination of a dedicated amplifier with the woofer allows for a more cohesive and dynamic sound output, making it a valuable addition to any surround sound system.

The Niles Audio PSW800 also incorporates advanced room optimization technology. This system allows the subwoofer to adapt to various room acoustics by optimizing its performance based on the environment. This is particularly beneficial for users who may not have a dedicated home theater space and need a flexible solution to achieve the best sound quality.

Convenience features such as adjustable crossover frequency and volume controls offer users the ability to tailor the subwoofer's output to their specific listening preferences and room characteristics. Additionally, the PSW800 includes both line-level and speaker-level inputs, ensuring compatibility with a wide range of audio equipment.

The sleek design of the Niles Audio PSW800 ensures that it can blend seamlessly into any home decor while providing a solid and reliable performance. Its compact form factor makes it suitable for various living spaces without compromising sound quality.

In summary, the Niles Audio PSW800 stands out in the crowded subwoofer market, providing a combination of powerful bass performance, adaptive technology, and user-friendly features. For anyone looking to enhance their home audio experience, this subwoofer delivers exceptional value and performance.
