I am looking into a new Sony(yeah, I know ) sub and they have 2 different subs that I can afford right now. which of these 2 would actually be better for bigger bass:

NEW LINKS:

Sony SA-WX700 -dual 10: sub: http://www.crutchfield.com/cgi-bin/S...=0&cc=01&avf=N

Sony SA-WM500 single 12" sub:http://www.crutchfield.com/cgi-bin/S...=0&cc=01&avf=N

these links will most likely not work by tomorrow.

I could just wait and save up enough money to buy a great sub. but like myself the wife also thinks it needs to be replaced asap. thanks for any suggestions.

p.s. I will not be buying them at this etailer but they had the most info for comparison.

the 12" sub has a frequency response of 24-170Hz and not the 20-200Hz as listed. however every site I check for the dual 10" has the same info as listed in the links I listed.

removed sony links due to editing links twice and them only working for 1 day

Just like car engines, subs are about displacement, displacement, displacement. Displacement is cone area times throw. The throw is determined the surround construction which limits how far the cone can move (and behave reasonably linearly) and whether you have the amplifier power to throw it that far. Finding the throw in the specs is sometimes hard, but pi*(d^2/4)*throw (vs room volume) is a pretty good figure of merit for how much bass you can produce.

If the throw is the same, then area counts, two 10" have more area than a single 12", but they are close enough to warrant looking at how surround is designed and how far voice coil can move.

The links don't work.

However, I would stick with a 12". Also, how big of a room are you going to use this in?

stupid links. I posted this on a few other boards and the links had to be edited over there as well.

the room is roughly 13.5 by 12.

All things being equal Iwould pick 1 12" sub for HT and 2 10" sub for music. If you want your sub to do double duty, I would go with the 1 12" because it goes lower.

I got a 12" Velodyne sub a year or two ago and never looked back, I didn't have one for years then one day I just had to buy one but wanted to spend the money on a good sub not a cheap one. because I knew this was going to have to last me.

This baby is just made for movies, you even feel it on the bath room floor in the same room when movies are on. If your buying a sub I would very much spend the money on a Velodyne over a sony anyday, Sony isn't know for great speakers at all and if you ask me I would get speakers from a company that only makes speakers.

like someone else just said, i prefer smaller cones for music, and bigger for home theatre.

im thinking of getting dual subs, one crossed over more for music (3 x 10's), and my current one for HT (3 x 14's).

the big cones go LOW, but arent as dynamic for music.

just get 2 subs

Joe Buck, did you buy this one?

Get a better price for it?

There is the problem of integrating the sub in the room. All rooms have standing waves so for a give sub position there will be nulls and peaks at different areas. The tough part is trying to minimize this at your listening position. Some highend subs and recievers now have filters to cut the peak out. The dual might be tougher for this.

Also all subs are not created equal. So maybe you should look for a better sub with a single 10 at the cost of the Sony dual.
