Axiom Home Page Forums General Discussion Home Theater Working with two different brand subwoofers

Pretty much Randy except when testing the subs to make sure they are working properly, additional output will increase by 6db with 2 subs, 9db with 3 subs and 12db with 4 subs.

For setting phase on sub C you will need to experiment with both settings. With 4 subs set up the subs across from each other like I suggested above.

I don't think I'll every be able to get 3 more 600's.$$$$$$ However, I've tossed the idea around about 3 more new350's or 400's possibly.

How big is that HT space again? I remember it was huge. In which case you may be better off adding a 500/600 to get the output.

Here is an old drawing back in the days of my 500, but should give you an idea. The 600 is now placed on the left wall right below the first wall treatment panel close to the front left speaker. I was thinking about putting the 600 back up front under the center channel since it looked cool. Then, get 2 or maybe 3 more subs.

One would go along the left wall, one would go on the shorter right wall below that panel, and the third could be daisy chained off the left one and maybe be placed along the back wall. My drawing is a little off as the back window and walkout door should be moved a bit to the right, so I have some wall back there for a 4th sub. The bad part is I would have a long coax going along the entire length of the side wall to the back wall.

There's nothing wrong in general(unless you mean aesthetics if it isn't concealed) with runs of coax that long, Randy. The losses are very small(especially at sub frequencies) until the run gets into hundreds of feet and can be disregarded.

Randy that space is in the order of 7000cf. You need output with that sized room if you want to feel the LFE bass. I would stick with the 500s or 600s. You don't need the benefits of a small sub in that huge space since even a 500 would look inconspicuous. For the $$s I would keep adding 500s or if you want them matched a 600 and then 500s. For the same price I would add 2 500s instead of 3 350v3s. A sub beside the seats and possible one behind the seats on the backwall would be worthwhile placement options depending how well you can dial them in.

Yes, before I bumped out the AV closet it was over 8,000.

thanks for the help. Now I just need to come up with how to fund this idea. Lets see, what can I sell.

You can always buy the drivers, the amps, power cables and the folded horns from Axiom and build the boxes yourself.

In my set up I really don't have a right side wall. That is, I have a left sidewall that runs about 12 feet, a front wall that runs about 20 feet, a back wall that runs about 10 feet. Obviously the right wall is about 20 feet away. My listening area is pretty much confined to the 10 by 12 area. Would you still recommend putting the sub on the right side wall even though it is so far from my listening area. There is also additonal basement area extending out from that front wall. Or am I better off confining my subs to the listening area.
Thanks

I'm running a SVS PB13 and HSU VTF-2 in my living room. Both are calibrated flat to 85 DB with the mains and running them together they run 3 db hot. I have phase at 0, as they are on the same wall and both up front with my mains. Run a splitter off the back of the receiver, turn one off calibrate, do the same with the other. Actually the amp on my old VTF-2 just went kaput so I'm trying to get it repaired now.
