Subwoofer for classical music listener

"I was trying to bring a concert hall (or cathedral) into my living room. Unrealistic."

rvpiano- good to see you were able to make an informed purchase, and outcome is positive. 

You're hearing what a sub can bring to the party. 

As mentioned in my page 1 post, I advanced a couple of steps into the "real" room, when I added a second sub. Playing with your location a little more and bumping the gain a notch may get you closer to hearing the pedal tones/feel of a 
17th century Cathedral organ. 

I play a number of LP's titled "Historic organs of..." They are a real acid test for my mid fi system. While I thought the single sub was fine, adding the 2nd was a game changer. You canget a closer approximation of the crescendo in the opening of Bach's "Toccata "with a sub(single or..) 

2 subs is like sitting in the upper level, and the usher has just escorted you to prime seats, stage level.

Happy listening with your new sub , and continue to fiddle.

Schubert: You're right. But right now I'm still in the "audiophile" stage.  When I settle down a bit I'll be "Bach."
But, the audiophile stage is a lot of fun!

tablejockey: I don't know where I'd put a second sub.  The opposite wall from the current sub has a doorway and a closet.
  I'm just enjoying the way it is now.
Maybe later I'll figure something out.

Sunfire True Subwoofer

I just fine tuned the bass of the sub by a method that some people might find useful.  Like, I'm sure, most new subwoofer owners, I had  the bass tuned higher than I should have.  Then I listened to two records of a classical symphony
 ( Mozart's 39th in Eb.)  By finding the balance (equal volume) between upper (violins) and lower strings (cellos and basses,) I got the best quality of sound.
I then tested many other combinations of instruments (including organ) and styles  (including jazz) and found everything to be in balance.

rvpiano-

I too, have the constraints of the system among a living space(no dedicated room)

My 2 sub configuration has BOTH subs equidistant to floorstanders  BEHIND the listening sofa-long walls. 
This pressurizes the room in a convincing manner. Bass envelops the room-but not is an obstrusive way. You end up dialing back the settings, as the subs work less.

As an aesthetic benefit, no unsightly giant boxes behind the floorstanders.
I have them on brass footers/4" maple slabs also brass footers(Mapleshade)

A single sub in my room was fine, but the second eliminated a room mode,also changing the very lowest of bass tones(slightly mushy) to a clearer,defined more convincing presentation. Finding the 2nd sub for cheap was the only reason for even considering the sub. I was happy with the single REL.

As a side note,  the 1812 Overture WITH cannons is glorious. A visceral experience-almost as if you're standing next to them!

Happy listening.
