If we were to judge the 901 in terms of the best sound available, then, we would say that it produces a more realistic semblance of natural ambience than any other speaker system, but we would characterize it as unexceptional in all other respects. It is ideal for rock enthusiasts to whom sheer sonic impact is of paramount importance.

如果我们根据最佳音质来评判901的话，我们会说它比任何其他扬声器系统更能真实再现自然的氛围，但在其他方面我们会将其描述为平凡。它非常适合那些对音效冲击力极为看重的摇滚音乐爱好者~ J. Gordon Holt - Stereophile

PERSONAL EXPERIENCES 个人体验: Listen to Believe! 耳听为品！ 🤩 
- 1st Impression, U will be Susprised HOW it can do Deep Bass at 30 Hz  w/ multiple 4.5 inch Drivers!
- Very Warm Tonality w/ Decent Imaging & Instrument Separation
- Very Laid-Back Presentation in terms of Soundstage & Scale, BUT it was Spacious, WIDE & BIG Soundscape
- Very Dynamic & Punchy, If u want to listen at CONCERT Volume, it will handle just fine without distortion

- 第一次印象，你会惊讶它竟然能用多个4.5英寸的驱动单元做到30Hz超低音！
- 音色非常温暖，成像和乐器分离度都不错。
- 声场和规模的呈现非常悠闲，但声景却宽广、广阔且庞大。
- 动态感和冲击力十足，如果你想以音乐会的音量来聆听，它也能轻松应对而不会失真。

SOUND QUALITY REVIEW（音色评测）:🤩
- Exceptional bass response when properly placed and equalized.
- Coherent sound across the spectrum with no crossover distortion.
- Capable of very high volume levels without distortion.
- Requires careful placement and high-power amplification to perform optimally.
- Can reproduce frequencies with clarity and speed, offering a live sound experience.
- Effortless dynamics and extended bass, making subwoofers unnecessary.
- High wow factor and ability to produce fundamentals at 30Hz and below.
- Marginal ability to tailor mid-range bass and treble through the Bose equalizer.
- Needs a minimum of 75 watts per channel for good sound; ideally, 250-300 watts per channel for the best experience.
- Spacious sound and accurate reproduction, but not suited for home theater setups due to the active EQ.

- 在正确放置和均衡后，具有出色的低频响应。  
- 在整个频谱范围内声音连贯，无交叉失真。  
- 能够在非常高的音量下工作而不会失真。  
- 需要小心放置和高功率放大器才能达到最佳性能。  
- 能够清晰、迅速地重现频率，提供现场音效体验。  
- 动态表现轻松，低频延展性强，因此无需使用低音炮。  
- 极高的震撼感，能够产生30Hz及以下的低频基础音。  
- 通过Bose均衡器可以略微调整中低频和高频。  
- 每通道需要至少75瓦特的功率才能提供良好的音质；理想情况下，每通道需要250-300瓦特的功率才能达到最佳体验。  
- 声音宽广、重现准确，但由于使用了主动均衡器，不适合家庭影院系统。

DESIGN & TECHNOLOGY 设计与科技:
- Strong build quality: Designed to handle high power levels, with some users noting their ability to take up to 400 watts per side without issues.
- Durability: Users have had these speakers for decades with minimal issues, though foam surrounds may need replacement after many years.
- Robust construction: Able to handle extreme power without distortion, even surviving unconventional tests (e.g., plugging directly into a 120V outlet).
- High-quality components: Though paper cones are used, they are praised for their sound accuracy and minimal inertia.
- Maintenance required: Equalizers may need occasional capacitor replacements to maintain optimal performance.

- 坚固的构造质量：设计能够承受高功率水平，有些用户指出每侧能够承受高达400瓦的功率而不会出现问题。  
- 耐用性：用户使用这些扬声器数十年，仅需进行少量维护，尽管泡沫悬边可能在多年后需要更换。  
- 结实的结构：能够在极高功率下无失真地工作，甚至在非传统测试（如直接接入120伏电源）中仍能正常运作。  
- 高质量的组件：尽管采用了纸质锥体，但其音质精准、惯性极低，备受好评。  
- 需要维护：均衡器可能需要偶尔更换电容器以维持最佳性能。
