Your new Velodyne subwoofer, like any good speaker system, requires proper positioning within the listening space to provide maximum performance. Improperly placed speakers may degrade the sound quality and reduce your listening pleasure. Depending on the size and type of furnishings in the room, perfect placement may not be possible. Finding the best location within your environment will likely require some experimentation. We suggest you experiment with the location during setup to find what sounds best to you when seated in your typical listening position.

INSTALLATION

Inputs

Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when connecting your subwoofer to a pre- amp, signal processor, line-level crossover or receiver with pre-amp level outputs. The SPEAKER LEVEL jacks connect directly to the speaker outputs of any amplifier, integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs due to their very high impedance.

Important!!!

Do not use both LINE LEVEL and SPEAKER LEVEL connections simultaneously!

Volume Control

This control allows you to balance the output from the subwoofer to the main speakers/amplifier in your system. This control should be set to achieve similar output level from both the main speakers and subwoofer when listening to music. A good starting point for the volume control is 3 or 4 dots from minimum.

Low-pass Crossover - 40 to 120 Hz

All inputs sum the left and right channels together, with the resulting signal passing through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s response will begin rolling off above the frequency you set this control to. You should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main speakers in your system. If your main speakers are smaller units with limited low frequency output, you may wish to choose a higher frequency

SPL-800i specifications

The Velodyne Acoustics SPL-800i is a highly regarded subwoofer that exemplifies performance excellence in home audio systems. Known for its powerful bass response and intelligent design, it enriches the listening experience by providing deep, impactful low-frequency sound without compromising clarity.

One of the defining features of the SPL-800i is its innovative DSP (Digital Signal Processing) technology. This sophisticated system optimizes the sound output, ensuring that the subwoofer reproduces low frequencies accurately across various music genres and types of audio content. The DSP-enabled design facilitates seamless integration with other speakers, creating a cohesive sound stage that enhances overall audio enjoyment.

The SPL-800i is equipped with an 8-inch downward-firing driver. This configuration not only maximizes the efficiency of the low-end response but also minimizes distortion, resulting in clean and precise bass output. The driver's robust construction ensures durability while delivering powerful performance capable of shaking the walls without losing musical fidelity.

Another notable characteristic of the SPL-800i is its compact form factor. Designed to fit easily into various home environments, it measures a modest size, making it a versatile choice for both small and large rooms. Despite its size, the subwoofer manages to deliver impressive power, with a built-in 300-watt amplifier that drives its performance.

The SPL-800i also features an adjustable phase control, allowing users to match the subwoofer output to their room acoustics and listener location. This customization enhances the overall sound quality and makes the subwoofer adaptable to different setups, whether in a dedicated home theater or a multi-purpose living area.

Further enhancing user experience, the SPL-800i includes automatic room equalization that helps in calibrating the subwoofer to its environment. This advanced technology assesses the space and adjusts its performance to eliminate unwanted frequencies, ensuring the best bass reproduction possible.

In summary, the Velodyne Acoustics SPL-800i stands out in the realm of subwoofers thanks to its unique blend of advanced technologies and thoughtful features. With its DSP technology, powerful driver, compact design, and room calibration capabilities, it remains a top choice for audiophiles looking to enrich their home audio experiences with deep, professional-grade bass.
