two 10's or one larger subwoofer?

Tmega,

I wouldn't be so worried as to the size of an actual driver. If you want to make bass from a driver you can either, all things being equal, move a large driver relatively slow or move a small one very fast. What this means is that you can get the same low frequ. with different size drivers. There are many different, and valid, ways to achieve the same result. The reason I requested you list your system is just for this reason. If you are using some, cheap, mass market, receiver that only makes power on a spec sheet, I can absolutely guarantee that a new amp will be a much bigger upgrade than a sub. Like the cops say, you just better come clean and tell us everything.

HaHa. My system is as follows: Anthem TLP 1 pre amp, Anthem MCA 20 power amp (200 watts per), Arcam DV137 universal player, APC H15 power conditioner, Wharfedale Evo 2 50 speakers (6.5" woofer, 6.5" mid woofer, 2" dome midrange and 1" silk tweeter), Ultralink Ambiance 8' speaker cables (10 awg), MAC & Emotiva interconnects and power cords. That's it full disclosure.

I recently designed a dedicate Home Theater for a friend. Using 'Golden Ratios' and good room construction...trying to do everything correctly.
When it came time to chose the sub(s), I chose 2 JL's.
There's a 'balance' that I hear when two subs are loafing along...placed in the right locations...that I never get with just one.
You may have other thoughts...that's fine, this is only my impression.

His room is seamless...the bass is terrific for my (his) taste.

YMMV.

Larry,

Thanks for that, my thought is that 2 would fill the room more evenly than 1. I just wanted some input from experienced listeners so I could draw my own conclusions. As for 2 JLs that would be way outside my budget.

Thanks to everyone for their opinions. Feel free to offer more I like to hear what others are thinking about this obsessive but enjoyable hobby.
