Hello, for those who own and use the Bose 901 speakers, im wondering if there are high frequencies coming out of the reflectant speakers- as in the 8 drivers facing the back/side walls. or are the high frequences coming only out of the direct and single driver in the front? All series welcome. I do not ask for any negativity on Bose or their products. please keep this peaceful. thank you!
a simple question for 901 users

I am not 100% sure, but the 901's have a HARD time with upper midrange, and high freq. That is just the design of the bose. I am 90% sure that the mid/high range is supposed to come out of the front. And the Low/mid range out the back driver.
But if I have my bose right, they do not have tweeters. They only have drivers, and this the problem with mid-high/high freq output.The Bitterness of poor quality last longer than the joy of low prices.- Bottom

I believe that all drivers in the 901's are "full range" drivers and that there is no crossover per sea.There are some things which are impossible to know, but it is impossible to know which things these are. :scratchhead:

I do not own anything from Bose, but I have installed a few systems. The 901 EQ does affect all the drivers, so high frequencies are sent to both the front and rear of the 901. Back when Bose shared some of its technical information with the great unwashed, it was revealed that cone break-up was supposed to force the dust cap to act as the tweeter.
There are many other companies that rely on cone break-up including B&W, Lowther, Fostex, and almost every home-built speaker using a full-range driver. Some are even called "high end." I don't own those brands either.- Bottom

I'm guessing that Bose was saying that at high enough freqs the only effectively radiating part of the cone is the center, including the dust cap, esp if it is rigid.- Bottom

For instance, at one frequency I'll call X, the voice coil and the dust cap riding on top of it can move forward at the same time the edge of the cone is still trying to move back. I once saw a dust cap moving furiously in and out while the rest of the cone looked to be motionless. Needless to say, that was from a very large and flimsy cone.- Bottom
