You're most welcome! There is alot of noise you have to dig through to get rock solid unbiased information, especially when people start chiming in all sorts of stuff with virtually no experience - the woes of the internet lol.
Anyways, on to your question. You most definitely do NOT want a bookshelf speaker that limited, especially for music. Now if you were really prioritizing movies, then I would recommend 5 or 7 bookshelves that have the flattest possible frequency response down to a minimum of 80hz, preferably 70hz. The reason why is that at 80hz, your ear cannot identify where the bass is coming from, so your brain won't be saying to you "The sub is right there on the floor". Therefore, your optimal crossover would be between 70-80hz.I hope that answered your question, please don't hesitate to ask more! :)
Awesome, I didn't know that! That makes sense! Thanks! I have a 2.1 system at home right now using bookshelf speakers and had the crossover frequency on my preamp between the sub/speakers set to 100hz. Do you think I should lower it to 80hz to get a smoother blend then? It doesn't seem to blend very well right now.
