What do you expect from a Sub in your home theater?
The reason I ask is my A3-300 sub right now just doesn't do it for me during movies. When I turn the gain up on the sub and for music it gives me the sound I desire. But only with music. At lower levels while watching movies I can leave the sub turned up and get what I want out of it to a degree. I had a listen to the tiny Definative Technology Supercube II. ! Now that gives me the bass I am looking for in a movie. Is it so much to ask that my sub hit me in the chest and make certain scenes in a movie make me jump and shake walls of my house? Yes I have it in the optimum position. I have tries just about everything and the A3-300 just doesn't cut it during movies. Maybe for others but not for me. I have a 2.1 channel setup that I use mainly for tv, movies, and music.

Add another A3-300 and you will most likely get the effect your lacking right now. DOubling the cone space,xmax and power will gain you a full 6db in output across the entire effective frequency band.

Your room will be the deciding factor. As long as they are grouped together there will be no phase or cancellation issues. Dont need to be stacked on top of one another if thats what you mean. Doubling the power and cone space has never given me results of anything less.

Agreed, get a second A3-300.

First of all "stacked" is just a term to mean close together when talking about multiple subs. If you subs are not close together the output will be more like 3 db's by adding the second. We've already discussed this. If you STILL think your right, go jump on the avs forum and ask Mark Seaton himself.

If stacked is your way of putting it, then we are on the same page.

It doesn't say they have to be close together to get the 6db's. If someone who doesn't know and reads it and thinks adding a second sub and putting it wherever will gain 6 db's, he is going to be dissapointed if they are at seperate ends of the room.

Actually I have seen well set up subs in opposing corners output the stated gain without question. Grouping them together just reduces cancellation potential.

I have a 2.1 channel setup that I use mainly for tv, movies, and music. I just received my A3-300 and it's a monster. If I had two of these in my h/t, I would literally shatter things. SOund is punchy and potent for h/t use. My room does have room treatments so that may be a big part of it.

Haha, nope, small room, big room, all that you need is for each sub to have a variable phase control to eliminate any cancellation at the prime seating positions.

You must be a used car saleman.

You must be a used car saleman. Seperating the subs doesnt mean your going to lose output by any means, especially if the subs are boundary loaded in corners. Room/boundary gain plays a significant role when properly implemented. As long as the subs are in phase your going to be just fine. Setting up countless dozens of HT systems has shown this time and time again. No need to roll those eyes...............

Yes of course, you are a installer now. I'll add that to your list of achevements. svsound.com/questions-faqs.cfm#dualsvs "What can you expect with dual subs then? If you are able to co-locate two SVS subs in a common corner of your theater or music room, you can expect (regardless of which size sub you have) roughly 6dBs increased "headroom" throughout the sub’s response" see the words common corner and roughly? Just type it into google, thats the first one that came up, among countless others. I'm done, You can keep this thread of lies!!!!!!!!!!

Just type it into google, thats the first one that came up, among countless others. I'm done, You can keep this thread of lies!!!!!!!!!! Yes, I was a sales and design consultant and did physical HT installations for quite a few years, this has been mentioned before in the past. But anyway, dirrect from the SVS site: I dont see where they say you CAN'T get 6db increased headroom by locating 2 subs in seperate corners. And the reason why they don't is because you can. But that "info article" by SVS is geared towards BEGINNERS. I bet that if you call them up and tell them that you have an accurate instrument(or even a keen ear) to adjust phase response and THEN ask them if you can get 6db of increased headroom from the subs positioned in different room corners(or wherever)properly in phase at the seated position and they will give you an astounding YES for an answer without doubt. In fact why don't you do that. Call them up, ask for an experienced technician(make sure to get his name)who understands room response and then post your answer back here. And then you can apologize for your last posts in this thread for the misinformation and ignorant comments and barbs, as I think your just being narrowminded and rude to an extreme now.

12" apart, that's a very small room. I assume you meant 12' ...
