## Products

### Genelec 8351B SAM Studio Monitor
```yaml
product: genelec-8351b-sam-studio-monitor
brand: Genelec
price_gbp: 3661.08
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
thd_at_90db: 0.05%
max_peak_spl: 118 dB
frequency_response: 32 Hz - 43 kHz (-6 dB)
crossover_frequency: 320 Hz, 2.8 kHz
frequency_response_accuracy: ±1.5 dB (38 Hz - 20 kHz)
```

- **Price:** £3661.08 [^1]
- **Summary:** The Genelec 8351B is a three-way SAM studio monitor with coaxial driver technology, dual concealed woofers, and GLM room-calibration support. Its wide bandwidth, high output, and controlled directivity suit professional mixing, mastering, immersive audio, and critical near-field monitoring.
- **Ideal For:** It suits the search for a studio monitor with the flattest frequency response curve because it specifies ±1.5 dB accuracy from 38 Hz to 20 kHz, while GLM calibration can further compensate for room-related response variations.

### Neumann KH 150
```yaml
product: neumann-kh-150
brand: Neumann
price_gbp: 1034.72
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
max_peak_spl: 118.7 dB SPL
frequency_response: 39 Hz - 20.4 kHz ±3 dB
frequency_response_accuracy: ±0.8 dB
```

- **Price:** £1034.72 [^3]
- **Summary:** The Neumann KH 150 is a DSP-controlled, bi-amplified two-way studio monitor with a 6.5 in woofer, deep bass extension, high output, and optional MA 1 room calibration. It suits professional mixing, mastering, and critical nearfield monitoring where accurate translation and low distortion are priorities.
- **Ideal For:** The KH 150 is especially suitable for identifying the flattest studio-monitor response because it offers a specified ±0.8 dB linearity deviation from 100 Hz to 10 kHz, a ±3 dB response from 39 Hz to 20.4 kHz, and DSP-controlled phase and frequency correction.
