Not have a subwoofer actually, because of the convalescence period of my bank account after the Genelecs and the stands…Your reply makes a lot of sense. I would agree to 5" woofers but not any bigger. Do you think the same fatigue rule applies when a subwoofer is integrated?
Subs can be connected or not, and generally provide a more coherent bass response, so in general will be more linear on the whole spectrum than 2.0 systems.
On the other side will require some learning curve to know the better place for them, phase alignment and room correction. Some people here have achieved good results in little rooms with the 7040 despite being designed for the 8010 or the 8020. Is a 6,5 inch subwoofer, as little as a sub can be. Buy only have 50 watts and 100 dB SPL, it will be my choice because I don’t give a tremendous importance to the sub bass region on my musical preferences.
I still think that better choose your speakers and after a while listening and enjoying decide if you need a sub or not. Personally I’m not sure, when I want to try something I speak with Thomann about the possibility of try and return, is present on its 30 days Money Back program but I prefer to talk about it to not abuse of the program.
