Im quite mad cause i cant compare those subs side by side to make sure which one is better. Anyway this forum has svs/dynaudio users so i hope you can help me. I cant decide between SVS 20-39PC+ and BM12S which is the same as Sub500 only meant for matching with monitors which i have. Info about my situation: room: rectangle shaped, 12 square meres, ceilling is 3m high gear: Dynaudio BM6A monitors with Presonus Central station, NAD CDP... system: i want to have 2.1 and all i need is a sub. Note that Ill use bass traps so i wont have such loss at 20-30Hz as the usuall small rooms have. Music is the most important, but i need power for movies...Dynaudio has only 250W which bothers me.But the price doesnt bother me that much (Dynaudio costs more) case ill use it for a long time. For me, Dynaudio sub is no more than 500USD more expensive than SVS. So what do you think, which one is better for me? Any ideas??
