```

- **Price:** £529.36 [^1]
- **Summary:** The Avantone Pro CLA-10 Passive is a passive, full-range two-way stereo monitor pair that recreates the classic 'white cone' reference sound. It uses an AV10-MLF 18 cm woofer and AV10-MHF 3.5 cm soft-dome tweeter and includes a TPC switch that drops HF output by 2 dB for a tissue-paper simulation. It suits engineers and producers who want a mid-forward, translation-focused monitor and run their own external power amp.
- **Ideal For:** If you want the most customizable passive studio monitors, the CLA-10 Passive uniquely adds the TPC switch to adjust high-frequency output by 2 dB while using the passive two-way crossover design and standard input connections (RCA and XLR combo/TRS).

### Amphion One15 2-Way Passive Studio Monitor - Single
```yaml
product: amphion-one15-2-way-passive-studio-monitor-single
brand: Amphion
price_gbp: 908.77
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
impedance: 8 Ohms
connections: Banana
driver_size: Tweeter: 1 in titanium; Mid woofer: 5.25 in aluminum
power_handling: 20 - 100 W
frequency_response: 49 Hz - 20 kHz ±3 dB
crossover_frequency: 1600 Hz
```

- **Price:** £908.77 [^3]
- **Summary:** The Amphion One15 is a two-way passive nearfield studio monitor with a 5.25-inch aluminum woofer and a 1-inch titanium tweeter, using a 1600 Hz crossover. It provides a detailed stereo image for tracking, mixing, or mastering, and is designed to translate accurately to other playback systems. It needs an external power amplifier because it is passive.
- **Ideal For:** For passive monitors with highly customizable amplification, the One15's external amp requirement and banana input connections let you pair it with different amplifier types while keeping its fixed 1600 Hz crossover, 8 Ohms impedance, and 20 - 100 W power recommendation.
