You are welcome. Be sure to look at both. I think the 6’s are still suitable sitting where they should, next to your monitors in an equidistant triangle with your head at the tip. High ends should be slightly above ear height and aimed slightly down at your ears. I am sure you can appreciate how 8’s would be rather bulky and block out all the sunlight us DJ’s love so much!
Seriously though. 8″ is pretty darn big. If you don’t mind and have the space, by all means go for it. With my style of working I wouldn’t need a sub either and 6s would do. If I were unsure, I’d still go for 6s and if I decided I need more umph, I’d get a sub (10″) after all.
Like I said, lot of it is personal choice, it pays to look at both closely somewhere, rather than be shocked when the boxes arrive!
