Thanks, really interesting info out there and a lot useful information. What I meant is music with double kick bass for example can have really fast bass hits and I would like to be sure that my sub can keep up with the speed and reproduce all hits clean without problems. As I have read some subs can struggle there, I do not know if its true or not.
Is there any comparison available between SVS SB13-Ultra and MartinLogan Dynamo 1500x? Or does any one here have experience from both? As those 2 subs at the moment are looking best in my eyes. SB13 being 1700€ and 1500x being 1800€ they are really close to each other in price and if I'm not wrong in performance as well? Would 1500x benefit from down firing configuration over SB13? Or does it even matter?
I can get 1500x from local store for testing without any costs, for SB13 I need to email lsound if they have some contract with UPS for returning shipping and how much would it cost. But good thing is that I'm not in hurry with this purchase.
