If you have a surround receiver, connecting a subwoofer is easy. In a 2-channel setup, it's often not. High-end audiophiles are a conservative crowd. Unfortunately, that means they are sceptical to "new" ideas like subwoofers and DSP / room correction - despite the fact that both can genuinely improve the sound in a 2-channel setup. Both features are a given on surround receivers regardless of price class. On stereo amplifiers, subwoofer output and active crossover support are often missing.

To get the most of your subwoofer, you should have a fairly high crossover, typically around 80hz. This will not yield good results if your amplifier doesn't have a highpass filter that relieves your main speakers of the same frequencies.

To help our subwoofer customers and others find amplifiers that will properly support a subwoofer in a 2-channel setup, we have decided to curate a simple list of amplifiers and preamplifiers/streamers that support this. 

If you are lucky enough to own our speaker systems, either the Sigberg Audio SBS.1 active speakers or the Sigberg Audio Manta wideband cardioid monitor matched with our subwoofers, this is less of a problem. Our speakers are high passed by design, and can be connected to any preamplifier for perfect subwoofer integration.
