One of its standout features is the 100W Class AB amplifier which delivers a peak output of 100 dB SPL, ensuring ample power with minimal distortion. Its frequency response ranges from 30 Hz to 200 Hz, providing deep and accurate low frequencies that are essential for a good subwoofer performance. The inclusion of a Bluetooth 5.0 stereo input is a significant plus, allowing for high-quality wireless audio streaming.

The subwoofer also includes a continuously variable lowpass filter and a defeatable highpass filter for fine-tuning the crossover frequencies, which enhances sound quality by ensuring a seamless blend with your main speakers.

However, weighing 17.64 pounds and with dimensions of 9.8 x 12.7 x 11.7 inches, the Eris Sub 8BT is fairly large and might not be suitable for very compact spaces. Its floor-standing design may also limit placement options in smaller rooms. Additionally, the product is not waterproof, which could be a concern if you need a subwoofer for outdoor or moisture-prone environments.
