Has Anyone Ever Run TWO Identical Pairs of Speakers ?

I plan to double Polk RT-2000p’s. They’re  listed in my profile at www.tinyurl/mcintoshrules if you’re that interested.

The only speakers I’ve heard recently that REALLY IMPRESSED me were:

Revel F328Be’s for $16,000/pair, and
Tannoy Canterburys for $15,000/pair.

I could buy either of these right now, but I really like sound of my Polk’s. 
Anthony Cordesman gave them an exceptionally rave review in Audio magazine in 1999 and he specifically  commented on their remarkable imaging and sound staging as well as their exceptionally good midrange and highs (his words, not mine). He was lukewarm on their low bass but that’s not an issue for me. 
I use a Sunfire Tru Sub MKII AND a very large great sounding Cambridge Newton P300D sub that uses six 6.5” speakers for subs in a push/pull configuration and they are remarkably fast in an 90lb. hefty metal cabinet. Unlike the Sunfire, there is virtually no cabinet vibration when it’s running because of the push/pull configuration of its six bass drivers.

My center channel sub is an 18” Hartley custom made for Jon Dahlquist when he was developing and voicing his DQ-1 sub he made to go with his DQ-10 speaker. I happen to know Jon personally and the dealership I worked for in back in the 70’s was one of his first dealer.

I also have two passive M&K Goliath II subs I cross over at about 80Hz with 4 Polk LS/FX two way dipole/bipole speakers I use for Dolby side surround and Dolby rear surround speakers.

And I  use four Realistic Minimus 7 speakers for Dolby Atmos speaker that will be crossed over at about 100Hz  with some small Definitive Technology active subs with 8”woofers.

I really can’t restrain myself for saying this, but I do believe I have my bass’s covered.😂

 I’ve listened over the years to many products Anthony’s reviewed  and I generally agree with him.

I found a second pair of mint RT-2000p’s for an exceptionally low piece so this will be an interesting low-cost experiment for me to hear what doubling them does . If two pair really suck, it’s been a vert low cost experiment for me.

But then there’s the possibility I could be incredibly surprised for significantly less money than a new pair of Revel’s or Tannoy’s.

I’ll know in about 6 to 8 weeks as I’m moving to a newer home with a much larger listening room. I’m on the wait list for my very busy electrician as I’m going to install a whole-house surge protection system and two 30 amp/120 volt circuits for my electronics.

as always, in all things audio , YMMV😎

@vynil_rules

I have a couple of subs for sale if you’re interested 😂

Yes I have run two pairs of  klipsch KLF 30  and Two  pairs of klipsch  CF4 together side by side 2 for left and to right but with separate amplifiers the same preamp 
first pair run on balance XLR to preamp Parasound P6 XLR output second pair run on RCA To P6 RCA output 
the goal here is make-sure  all speakers tweeters are on the same ear 👂 level believe me it doesn’t have to be the same speakers 
I have try klipsch chorus ii and KLF30 combo klipsch KLF 30 and CF4 combo and forte and chorus ii combo…… if you set them right you will never go back to single speaker again 
the benefit outweigh the lost 
any 2 channel preamp with balance XLR and RCA output can do that not on AVR though 😂😂😂

I have a pair of Martin Logan’s ESL X’s and a pair of Vandersteen 2’s and running them with VTL mono blocks and I have to say when they are all on the dynamics are impressive and the bass response is awesome I haven’t played with placement for depth yet, it’s a work in progress and now I just repaired a pair of Thiels with repair work done by Rob at Coherent Sound (awesome service!) and look forward to listening to them as well just have space limitations.

@jasonbourne52  You are correct.  Stacked Advents were the bomb back in college.  Henry Kloss was a great guy as well.

Years later we found out that the speakers were pretty bad--there are MANY that are much worse, they they are pretty bad.  You have to actually LISTEN to them with good hardware to figure it out, but like most box speakers, they are pretty bad ("bad" meaning "inaccurate reproduction" of the music).

Still, back then they were considered quite a breakthrough, and if you could afford the better walnut cabs, they even looked nice.

Regarding stacked, yes, there were many discussions back then of how tweeters should be aligned, etc., how far away, etc., etc.  

As for various comments on "tall" speakers, gee, wonder where they got that idea?  Was not from Jim WIney, I am sure.

Finally, regarding stacked Quads in the HQD system, we made some of the stands for quads for Levinson (VERY slow payer) and some of the 24" Hartley woofer cabs. We listened to them next to Maggies.  Even back then we could easily identify listening fatigue from the Quads, which are shrill and have a number of other issues regarding delay, etc., that you can easily hear.  The Decca ribbon tweeter in the middle of the stacked Quads was interesting.  Running them with Levinson gear back then (when it actually worked) made the sound so bad we had to turn them off. 

REALLY bad!

Side by side with the Magges...NO contest.

Cheers!
