Sonic Characteristics and Limitations of Bose 901
Where traditional speakers need to stay away from walls, the Bose 901 excels at room corner placement, due to most of their speaker drivers facing backward. Trial and error of the speaker placements are required, as you need to explore to find which position has the best stereo imaging (to you that is). In terms of visual and optimal speaker placements, it may be a bit difficult to fit the Bose 901 speakers into most modern homes. Aesthetic-wise, it would be a good match with vintage amplifiers. You will also need to make space for a Bose Active Equalizer.
There are a total of nine 4.5 inch (114mm) full-range Helical Voice Coil drivers (Series VI) and three reactive air columns. The nominal impedance is 8 Ohms and the recommended amplifier power is between 10-450 Watts (RMS) which is a really wide range. The estimated speaker sensitivity is between 90-92dB. The bass response is impressive, but it starts to diminish a lot after hitting 40Hz and below. It is still quite difficult to gauge but it seems to be an efficient speaker and may not be as power-hungry.

Speaker placement and positioning are entirely up to you, there’s no real need to forcefully push them to the corner but the stereo imaging is overblown which kind of sounds interesting. The soundstage is huge and is so entertaining to listen to when placed nearer to the corners. As mentioned you should experiment yourself in terms of Bose 901 speaker placement. The large and spacious soundstage which the 901 ‘exaggerates’ is amazing for live concerts/performances, the stereo imaging is excellent which makes the whole music delivery very alluring and enjoyable.
Yes, Bose 901 has that special ability to engage your senses in a unique way and that versatility to place them almost anywhere in your listening room. The bass reproduction of the 901 speakers certainly exceeded our expectations, it is punchy and full-bodied, and they can stand their ground without needing a subwoofer. The EQ can further boost the bass if you want to. The details are sought of lacking but the fun factor is worth the trade-off I guess. At this price point, we couldn’t really complain much.
The Bose 901 speakers are easy to listen to, all thanks to the EQ which enables you to adjust the settings and calibrate the speaker to suit the room.
