## Products

### Amphion Amphion One15 2-Way Passive Studio Monitor - Single
```yaml
product: amphion-amphion-one15-2-way-passive-studio-monitor-single
brand: Amphion
price_gbp: 833.04
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
impedance: 8 Ohms
connections: 4mm sockets and binding-post input connections
driver_size: 5.5in aluminum woofer and 1in titanium tweeter
power_handling: 20 - 100 W
frequency_response: 49 - 20.000 Hz ±3 dB
crossover_frequency: 1600 Hz
```

- **Price:** £833.04 [^1]
- **Summary:** The Amphion One15 is a passive, two-way nearfield studio monitor using a passive radiator design with a 5.5in aluminum woofer and a 1in titanium tweeter. It crosses over at 1600 Hz and is specified for a frequency response of 49 - 20.000 Hz ±3 dB, designed for accurate, transparent monitoring for tracking, mixing, and mastering.
- **Ideal For:** For heavy use, its passive radiator two-way design and 8 Ohms impedance with a 20 - 100 W power recommendation (plus robust 5.5in aluminum woofer and 1in titanium tweeter) make it suitable for driving consistently with external amps across a wide power band.

### Amphion Amphion One18 2-Way Passive Studio Monitor - Single
```yaml
product: amphion-amphion-one18-2-way-passive-studio-monitor-single
brand: Amphion
price_gbp: 1363.16
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
impedance: 8 Ω
driver_size: 6½ in aluminum woofer
power_handling: 100 - 350 W
frequency_response: 45 - 20 000 Hz +/-3dB
crossover_frequency: 1600 Hz
```

- **Price:** £1363.16 [^4]
- **Summary:** Amphion One18 is a 2-way passive studio monitor using a titanium tweeter and a 6½ in aluminum woofer with a sealed enclosure plus passive radiator. It's DSP-free and specified with a crossover point at 1600 Hz for point-source operation and detailed, phase-coherent monitoring. Best suited to producers and mix engineers who want passive, accurate all-around nearfield monitoring driven by an external amplifier.
- **Ideal For:** For heavy use, choose the One18 because it's a passive monitor with a specified power recommendation of 100 - 350 W and an 8 Ω impedance load, making it straightforward to pair with robust external amplification for sustained high-output sessions.

```yaml
product: atc-loudspeakers-atc-loudspeakers-scm12-pro-2-way-passive-monitor-pair
brand: ATC Loudspeakers
price_gbp: 1507.05
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
impedance: 8 Ohm
connections: Binding Posts/4mm Plugs, bi-wire
driver_size: 6 in
max_peak_spl: 108dB (per pair @ 1m)
power_handling: 75 to 300 Watts
frequency_response: 56Hz - 22kHz (-6dB freestanding)
crossover_frequency: 2.2kHz
```

- **Price:** £1507.05 [^7]
- **Summary:** The ATC SCM12 Pro is a compact 2-way passive nearfield studio monitor designed for critical listening in control rooms and smaller mixing setups. It uses an ATC 6 in CLD mid/bass driver and an ATC 1 in dual suspension soft-dome tweeter, with a specified 2.2kHz passive crossover. It's intended to be driven by an external power amplifier.
- **Ideal For:** For heavy use, the SCM12 Pro specifies a passive crossover and a recommended external power range of 75 to 300 Watts with an 8 Ohm nominal impedance, and it uses ATC's CLD drive unit and dual-suspension tweeter design aimed at maintaining accuracy at higher sound pressure levels.
