I'm thinking of adding another sub to my 2 channel set up, and was wondering if it's worth the money, I would replace a Paradigm Servo 15 with 2 smaller 10" subs, augmenting my Spendor SP1/2's, Comments? Thanks in advance to all.

... if you buy one subwoofer rather than two that leaves MORE money for the main speakers which are the most important component correlated to the overall sound quality of your system.I'd consider upgrading the main speakers before trying to improve the bass from a mono Servo 15 subwoofer: The Paradigm Servo 15 is a very good subwoofer when used with a decent external 24dB/octave crossover. The external Paradigm crossover does not seem to have a steep enough low-pass filter and only sounds good with crossover frequencies of 50Hz. or lower, IMHO. (50Hz. is okay for full-range Paradigm 100 speakers but 50Hz. is too low for many small speakers).
When using one mono subwoofer (as I have for the last 11 years -- I used stereo subs for 14 years before that), you must sharply restrict output above 80Hz. (If you can hear ANY male voices through the subwoofer when the other speakers are turned off, there's too much output above 80Hz. and you should be using left-right stereo subwoofers).
A mono subwoofer with too much output above 80Hz. has to be placed half way between the main speakers to integrate well with them ... and if that location is also half way between the side walls (as it often if with two-channel stereo in a rectangular room), the bass frequency response will be weak compared with one off-center mono sub or two left-right stereo subs.
and became so accustomed to the advantages of this setup that I could never go back.Although most vinyl has the deepest bass summed to mono, this is not the case with many (most?) digital sources. And, depending on whether or not you listen to classical music, I can assure you that most of this has the bass info in one particular channel. (Rarely are tympani center stage.)
using the amp outputs to feed speaker level to both sub and speakers. Unfortunately, duel RELs will cost money and I'm not how much they can contribute on the bottom end to VA Mahlers.
I use 2 Rel Storm IIIs with Thiel 7.2s and they do add something. Granted it is on mat'l that has real bottom end but it is noticed when the subs are off.
Thiel 7.2s, those look like (almost) full range speakers which should work on their own nicely for most music. I have eyed a REL Studio III on closeout for quite a bit of time but since there's only one....I'd have to ensure the crossover is set low enough so I wouldn't notice it's location when it was working.
My subs are set at the lowest setting, 22HZ. When I first re-hooked them (7.2s) up after I got my Bryston 14BSST amp I had a friend over and I put on one of my reference cuts I use for bass - Al Dimeola's "Kiss My Axe" - the 2nd cut. About 2/3 of the way thru the cut there is major bass drum kick. My friend upon hearing the 14BSST with the 7.2s thought I did not need the subs until I replayed it with the subs on. Yes, they do nicely on their own but with certain things you definitely notice the difference.
