#54 Thomann Swissonic A306: $250 per pair Discontinued Thomann $250 eBay
Older model: the Thomann Swissonic A305 (rated 4.2/5). See every Swissonic A30 generation.
Pros: Affordable studio monitors with useful bass and tone controls that make a capable budget setup when carefully tuned. With the treble control set to -2dB, Erin measured a 7.29 ideal-subwoofer score and 43.9Hz -3dB bass extension. This is a useful affordable monitoring option when carefully set up, with onboard controls for basic tonal adjustment. Measured bass extension of 43Hz (-3dB), with a measured sensitivity of 89.9dB.
Cons: The published result is not the flat-control setting: it specifically uses -2dB treble. Even then, the response spans 2.8dB from 300Hz to 5kHz, so balance is not as even as the leaders. Bass output and vertical listening position remain practical limitations. Discontinued.
