Choosing Sub-woofers. Please advise ASAP.

Tim, thanks for providing us all with some excellent inputs and food for thought.

On a different note altogether, I would ask the OP in all seriousness if he has considered the ability of the listening room floor, and its support structure, to handle the weight of all this stuff. By my calculations, including the not particularly heavy E-110 subs the equipment that has been listed weighs a total of about 1600 pounds. And given that the kitchen is adjacent, the listening area is apparently not in the basement.

Seems like a lot of stuff and a lot of weight to be putting in a 16 x 14 foot room, in addition to equipment stands and racks, source components, furniture, and people. And even more so if you were to go to larger subs and/or more subs.

It is a lot of stuff in a smaller room sound wise as well. Benefits of proper subs with good full range speakers and amps to drive them is more marginal but still real.   It's all a matter of how much of a total assault is really needed or desired.  

Hi Al,

     Good point about the weight, 1,600 lbs is no joke.

      I have no idea what the weight capacity of a typical living or family room above a basement would be.  I would think it all depends on the supporting structure underneath.  If there were a few steel i-beams that are supported by a number of steel posts that are anchored into a basement's concrete floor, the weight capacity might be substantial.

      Do we know for certain there even is a basement below his room?
     If it's on a slab, the weight capacity could be extremely high.  

   Truth be told, the op is starting to tick me off.  I'm getting the impression he's not even reading my replies so I seriously doubt he'll listen to my advice and add 2 extra subs. I think he's asked for assistance but already has his mind made up of how he wants to do things.  .

     I'm fairly certain he's going to be disappointed in the results but I can only lead a sautan904 to water, right?.  If the yahoo doesn't want to drink, then he probably deserves a room with poor bass response.  

Later,
 Tim

@ Al

I have a wood floor on concrete so not an issue with weight. :b

@ Tim

I read your post then I got lost. English is my third language and when I see super long writing, I got lost. Thank you for trying to hhelp. Anyway, one dealer will help setup stereo and another will help setup HT. Eventually the Wilson Dealer will do the final tuning for both. I just have to give the HT dealer the job cause originally I went to him for budget system but then I change my mind and I could have bought all Mcintosh gear and wilson from the Stereo dealer but I feel bad cause HT dealer helped me so ended up I split up the purchase.

I hope they will do great job for me.

Good!

Another factor that should be considered is how all this equipment will be powered. Assuming 120 volt AC the four McIntosh amplifiers have specified current draws (presumably when outputting maximum rated power) that total 44 amperes, although under typical listening conditions I would expect that number to be much less. But the current draw of multiple subs on high volume bass transients will add to the total considerably, at least for brief instants.

So it would seem probable that dedicated runs from at least two 20 amp circuit breakers will be necessary.
