Subwoofers.... one 10" or two 8"?


I'm looking to fill out the bottom of my simple 2 channel system  (Musical Fidelity X-Ray CDP through Peachtree Audio Grand Integrated amp to a pair of Mirage OMD-15 full range speakers).  I occasionally will play the TV audio through the system for movies, but not interested in an HT setup. Music is the prime focus. The room is "medium" size.  I know that will not give the deep bass feel of a 12", but the difference should not be too great, and a 12" may be overkill for that room.  I've also considered getting two 8" subs to keep the sound balanced between the left and right channels. I think the  8" may be enough bottom for my room and tastes. I'm on a budget so getting a pair of anything bigger than 8" may not be in the cards.

Any opinions or suggestions as to whether I'd be better off with one 10" or two 8" subs?

Your 8/13 2:27AM post seems very helpful.  THANK YOU.

I'm planning to try it integrating SVS SB1000s with Silverline Prelude Pluses that claim a lower end of mid 30s Hz.  

For anyone interested, an on-line tone generator is available at the link below.

Eric sorry i was speaking in broad terms like mids etc I suggested gik bas traps i use them and with a few other panels an diffusers it changed my game . Gik was just saying in general terms have a freind hold a mirror for you against the reflection wall until you see your speaker and start by treating that area with a panel etc . Obviously not accurate for all app my speakers are 4’ from the side walls corners are trapped . This all becomes meaningless if treatment is not an option
.
    Ghosthouse just curious why the svs no gripe or pro for it just curious for your decision over others
Hi Eric,
Beg to differ. Easiest and most accurate is the method I described very briefly. All you need is: play a test tone at the crossover frequency with reversed cable polarity at the speaker, listen for the null as you adjust the phase, correct cable polarity and done.. Don’t want to write a chapter on it so I posted a couple links. "Soundoctor" Barry Ober, tech support at JL Audio sells a disc for $20 with test tones and a variety of other tools for optimizing subwoofers, along with instructions for the why and how of it.

Cheers.
Um, yeah if that’s all you are trying to do. However you are not guaranteed accurate amplitude or phase matching above and below that point.

I’ll give you that it’s quick and good enough for many, but it's hardly comprehensive.

oleschool -
Reasons for going with the SVS SB1000s are:
1) sealed design
2) 12 inch driver
3) rated into mid 20 Hz
4) small size
5) weight - I can move them around without needing a chiropractor
6) continuously adjustable gain & cross over as well as phase
7) line level and speaker level inputs
8) 45 day money back in home trial (free return shipping during that time)
9) 1 year money back on trade up
10) 5 year warranty
11) generally favorable reviews...both consumer and professional
12) great price (got a pair of SB1000s for <$1000 with free shipping)

Still messing around with settings but they look like keepers. Only thing I’m not crazy about is the black ash finish. Wish they offered a mahogany or cherry...even if it were veneer.
