How Is Bass Divided Among Speakers If No Sub?

How is the bass divided among speakers if there is no sub in the home theater system?

If a 5.1 system has identical speakers all around with 15 inch woofers and all of the speakers are set to "large" on the processor, does the serious bass get evenly distributed to all speakers? Say, like an explosion or a dinosaur stomping?

Is there much serious bass info sent to the surround speakers if they are set to "large"?

Like already mentioned, when you go into your receiver's settings you tell the receiver "yes/no" you have a sub, if no the LFE goes to the mains. When set to "large" your speakers run full range, when set to "small" it engages the crossovers and anything below your crossover point is redirected to the sub, if you had one. You have 15's which are larger than most subs I wouldn't worry about any damage, set your receiver to "no sub" and "large", this way you will hear all that's on the disc within your speakers capability. I have a system in one of my rooms with in-walls and no sub, I have had no damage there or any other set up not using a sub.

If there's no .1/LFE speaker in a speaker configuration, then that channel's info will not be played and any bass info redirected from non-full range speakers, if there are any, will not be played over the system.

Any speakers configured as large/full range will get all of the bass info that was mixed for that particular channel. Any speaker set up as non-full range/small will get a limited signal based on how the surround processor/receiver is set up (eg, crossover points).

In your setup, you'll get all of the bass info that was in the mix except the .1/LFE info. That means you'll be missing some of the really intense bass in a soundtrack.

  LFE should be directed to the large speakers if Sub is set to none. Read some articles on "bass management" or the manual for your pre/processor or AVR.
  
  There are devices out there which do not properly implement bass management. I know my old Technics SH-AC500D didn't do it for DTS (so I had to use an analog active crossover for bass management and phantom center). And some more recent AVR had a bug where bass management didn't work for PCM stereo sources (possibly the Onkyo 608).

    While most surround processors/receivers will do this (reroute to the mains if they're set as large), it could easily lead to speaker damage. See the first line of #3:

  Thanks Joe. I can do without the really intense bass. My neighbors will be outside my door with torches and pitchforks if I had a subwoofer.
  
  I share a walls with neighbors on both sides of me in my loft.
