EDIT: Didn't want to bump the thread, so I thought I would say thanks in an edit. I read every post twice, thanks for all the info/recommendations!
Hey, long time lurker first time poster. Just wanted to say that this is a really cool site and I've soaked up a lot of good info, although some of what you guys say goes right over my head and out the window...
My theater space is in the living room, which is open to 2 hallways and the kitchen/diningroom. Dimensions are 23 x 28 x 9 ft. My current system is a HTiB, the Yamaha YHT-399.
Anywho, about my question, I am not much of a high-end connoisseur and so was wondering if I would be able to significantly appreciate the difference between these two sub configurations.
4x Yamaha YST-SW012
Or,
1x SVS PB13-Ultra
The HTiB comes with one YST-SW012, so I would only need to buy three more.
This would be for 90% movies, 10% music. I don't really need earth shattering bass, just looking for what I need to give movies some presence in my large space. Is the PB13-Ultra more sub than I can even appreciate? My budget isn't infinite, I can't actually afford the PB13 just yet, but if it's totally worth it I can wait on the Yamahas' and save up.
I probably come across as a caveman, but please have mercy and grant me more knowledge.
Thanks for your time.
