Has Anyone Ever Run TWO Identical Pairs of Speakers ?

Son, you are an adolescent troll in this discussion amongst the big boys,  AND you personify the definition of a Drug Store Audio Cowboy: One who criticizes and/or offers opinions on products they HAVE NEVER LISTENED to, and is perpetually standing outside the grown ups listening room enviously staring in.

As I previously stated, unless you have actually LISTENED to Polk RT-2000p’s, any thoughts you have regarding them carry less weight than the electrons you wasted posing your drivel here. Be gone, troll😩😩😩

Re: Bose 901I’d like to nuance the Bose 901 evaluation in this thread - intrigued also by the ’super bose’ system described above by g_nakamoto .

I used 901 mk 2 in the 70s and 80s. Were they bad? Well, in some respects, not others. I eventually changed to conventional speakers later, including Dynaudio Consequence.

So what about the 901s? I found that:

1 They needed to be setup exactly right. The wall behind the speaker played a surprisingly large role - solid slightly uneven brick wall gave the best sound (e g better than a wood wall).

2 They sounded good on "big music". Turn on Pink Floyd, and my friends would be impressed, back in the 70s. Even more so, when I changed from a Revox A78 2 x 40 w amp to a Yamaha 2 x 120 w, resulting in better and beefier sound. "Beefy" is maybe the catchword here. Not pinpoint by any means. But quite impressive.

3 What eventually drove me nuts was the equalizer supplied with the 901 speakers. Yes, it flattened the frequency curve, but it just did not sound good. I came to hate it, and in the last years, I often just disconnected it, even if the frequency curve then became A-formed. I never found a good alternative equalizer. At that point, and listening to the gradually improving conventional designs among my audio friends, I sold them, and bought speakers resembling Proac 3.8, and later, the Dyn Consequence.


But this is a nuanced story of an interesting product which wasn’t "terrible" or "deeply flawed" even though it had a lot of problems.

We had a lot of fun, back then, I could bring the 901s to parties, plus a good amp, and they would certainly get people dancing.

It is not really surprising that the 901s sound very different depending on the wall behind them. They mainly play "through" this wall - through reflected sound. I did read the engineering concept texts made by Bose, for the innovative 901s - but even for me, it was a surprise to hear them - should we say - "grasp towards pinpoint" - optimally placed with a totally solid stone / cement back wall, and also, a wall with some uneven dispersion, like a brick wall where the bricks are maybe half an inch out from the cement. I discovered this, bringing them along to an event at the University of Oslo. I never heard them that good, at home. 

No affiliation to Bose - or anyone.

I had previously written Now I have a problem: They sound so good that I guess I now need yet another pair for parts/backup! 😳😳😳

As fate would have it, yet another pair of Polk RT-2000p’s fell into my lap for only $250, so now I really do have spares for parts, etc.

And doubled speakers are not a new concept. Advent, in particular, comes to mind. Double Advents were a popular and very good sounding system back in the 70’s and 80’s: You had to spend quite a bit more to get something that sounded substantially better than double Advents. And even the ultra-high-end dabbled in doubled speakers with the introduction of Mark Levinson’s massive HQD system.

More recently, Wharfedale is suggesting double Linton speakers (https://www.audioemporium.com/wharfedale-linton-iterations/) and one of the UK’s top reviewers I occasionally correspond with listens to doubled BBC LS5/3A’s at home. IMHO, doubling LS5/3A’s makes perfect sense as you get +3dB more volume, a big plus in generally smaller rooms in UK homes. And I can only imagine how much better a doubled pair of LS5/3A’s sound compared to a single pair of the already great LS5/3A’s. As always, YMMV 😎

I had one speaker upside down so the tweeters of both speakers were in the middle

Same, this is what you should do turn the top one upside down and with Blutac between them, stick it on top of the other one so all tweeter are as close as they can be, so now you have a large tower speaker. (nick named fliped stacking)
