Bose 901...really

The 802 is used without the single driver on the front, and with all 8 drivers facing the listener (turned around from the reflecting home version).
These have had some popularity, I can remember hearing them from time to time and they are ok for some applications but not completely full range. Check out the inside spread of the album Little Feat "Waiting for Columbus" shows a set of Bose 802's used for stage monitors in the rear.

Since the speakers are designed to take advantage of reflected sound, there is a logic in your proposition.

However, it's Bose's logic that I can't quite rationalize. Bose are suggesting, correctly in my view, that you hear a lot of reflected sound as well as direct sound, hence their direct/reflecting speakers. So far, this seems logical.

However, if you record stereo using a traditional recording method, a pair of microphones in Blumlein configuration for example, then you are capturing reflected sound in the original recording, as well as the direct sound. So since you have already captured reflected sound in the orginal recording, what is the logic of reflecting it again with the speaker? It seems that it would just put you another step away from the original music, with more opportunity to mess things up in some way.

On the other hand, it's not a high fidelity situation anyways, so why not have some fun. Give it a try and tell us how it turns out.

Well, I ordered a pair.

Markphd...Exactly. It's for fun, not audiophile listening.

That said, I must admit that I have heard some Bose 901 setups that really were good. I think that they require a large room with high ceiling, and an uncluttered front wall for them to bounce their sound off. This is exactly what I have.

In spite of all the reflected sound they can image quite well. I believe that this is because the single front driver sound arrives at the listener earlier than the reflected sound, and time-of-arrival is very important in the sensing of sound location.

The owner's manual, which you can download, goes into detail about how to hang them from the ceiling. I never saw an owner's manual mention this option. Hanging speakers is a controversial topic among audiophiles, but the ones who say it's a lousy idea have never tried it. I intend to set up that way.

The Bose are intended for Rear channels. However, I will be able to compare them with some well regarded Dynaudio monitors with subwoofers at the front. Anyone want to make a bet?

During the late 80s I was stationed in Greece where the houses/apartments were usually concrete walls. I had a pair hanging in a large room. The ceiling was parobably ten feet high and the speakers were more than six feet off the floor. Was I listening to audiophile accuracy? Hell no. Was the place rocking? You bet.
I had a Sansui B2101 200 watt amp pushing them. I remember listening to Pink Floyd as loud as I could stand it. Thanks for the memories.

Given my luck with lottery tickets, I don't know whether I'm much of a betting man. However, I'm going to go out on a limb and suggest that the Bose will do very well indeed against the Dynaudio. I think that the Dynaudios are meant to be in a more traditional setting. Your setting seems to be playing up to the Bose's strengths. It's been a long, long time since I heard 901's so I don't really remember. However, I have certainly read many reports that the 901's are good speakers. Just because Bose don't work the high end of the market doesn't mean they're not capable. As an analogy, that downscale car company, Fiat, do pretty well with their upscale brand...what's it's called?...Ferrari is it?
