Are big subwoofers viable for 2 channel music?

I don’t know about big Subwoofers, but my two little JL Audio Dominion D108 Subs certainly pack a punch and filled a big room quite nicely with my Goldenear Triton 5’s. They’re powerful little Subs.

Legacy Audio XTREME XD Subs in use. See my review at Dagogo.com 

I have at times used from 4 to 12 15" woofers employed in systems. It's fascinating to hear the gradations of power, dynamics, smoothness, ease, tonality, etc. that occurs in different configurations of large drivers reaching down well below 20Hz.  

Hello douglas_schroeder,

     I have never employed 4 to 12 15" woofers in my room or systems in different configurations of large drivers reaching down well below 20 Hz.  I've only employed a maximum of  4 10" woofers/subs in a single optimized configuration, that reach down to 20 Hz, but not likely much deeper, and were included in the Audio Kinesis Debra 4-sub distributed bass array (DBA) system I've been utilizing in my room and systems for the past 5 years.  
    Since employing the AK Debra 4-sub DBA system, however, I have become very familiar in experiencing and enjoying very high quality bass performance that you very aptly describe as having the qualities of "gradations of power, dynamics, smoothness, ease, tonality, etc."  I would only suggest adding speed, accuracy, detail and naturalness to your list.
     But your apparent endorsement of employing subs with larger woofers and in quantities beyond 4 subs to reproduce bass well below 20 Hz and even further improve bass performance, both surprises and somewhat confuses me.
     It's my understanding that reproduced bass tones below 20 Hz are not audible, mainly just vibrate things around the room including parts of our bodies, there are very few musical instruments that produce bass below 20 Hz with pipe organs being the only ones I'm aware of and there being virtually no commercially available music recordings containing bass frequencies below 20 Hz.
     I prefer bass that sounds and feels natural like when music is played, heard and felt live in person at smaller venues, not like over-amplified arena rock bass.  What am I misunderstanding about music bass below 20Hz?

Thanks,
Tim
 
   
 

You don't know what you are missing until you experience it. 

Frequencies below 20Hz add realism when watching movies. In real life if a train rolls by, or there is a gun shot or explosion, there are frequencies you feel. The sensation added by low level deep frequencies can contribute to emotion during movies. The ability to reproduce those frequencies is a good thing. 

There are frequencies below 20Hz used in some of today's music. 

Smodtactical, the best advice you have received is to listen. When things settle down from the virus, find as many listening opportunities as you can. Continue to do research here and other sites. 

The construction of your room matters (concrete or suspended floor etc.) Your preference for bass matters. Some people love sealed subs, others do not. 

I have two JTR S2 subwoofers in a 14x29x8 room. I use a mini-dsp to adjust the subs. There are times I have caught myself thinking, wow, I paid all that money for these subs and I can't even hear them. Then the music or sound track calls for it and I get a big smile across my face. These subs are special. 

You are planning a large room, bass requires displacement of air. Larger drivers move more air. 

I am in SC. You are welcome to come listen when things are safer. Oh, by the way, my in room response is +/- 3 db from 100 to 6 Hz. I have also added a BOSS platform as detailed in The Hideaway Theater thread on another forum. Large sub-woofers can be great!

Enjoy the journey, and have fun!

John I like your approach. I infact may go dual RS2s as well. But I might go ported just to maximize the low end extension especially for movies with the captivator 4000.

Or sealed S7201 or ported TV42Ipal.
But I think im settled on going for big subs.
Another approach would be 4x 18 spread around my space for a smoother response.
