The Chorus Vertigo is designed and manufactured by a Finnish Chorus/OR company. It houses a very well known Peerless XLS 10" woofer in a transflex enclosure. The frequency response is extremely flat with a pretty good 23 Hz extension. The crossover has a wide operating range and around 4th order slope. Output stays pretty linear up to 100 dB, though THD jumps up due to amp clipping. The port is only 3” and has no large flares, thus resulting in an audible port noise at higher levels. Group delay stays low down to 35 Hz, ending up just above the 1 cycle curve at lower frequencies. There’s around 130 ms of excessive ringing near the tuning frequency/high pass filter at 25 Hz. Spectral contamination tests shows low overall distortion at 90 dB level. It couldn’t handle this test at higher than 95 dB level, indicating that the Chorus Vertigo is most comfortable at low to medium listening levels. The overall build quality is good.

+ Pretty good extension and good shape of the frequency response
+ Low distortion up to medium output levels

- Amplifier can clip really audibly
- Port noise
- High distortion at high output levels
