ARX A5s would be the Best or "king of those models", bigger sound-stage is a great reason to pick floor-standers. A3s would just have a little less bass extension.1) Other than bass extension, is there any difference in sound quality between the Arx A1b, A3, A5 (i.e. sound clarity, soundstage depth, imaging, etc.)?
2) If crossing over to outboard subs at 80hz, is there any advantage to using either of the bigger towers instead of the smaller bookshelf (i.e. amount of SPL, etc.)?
I've read many discussions on the general advantages and disadvantages between bookshelf and tower design (...tower speakers can put out more SPL because of bigger enclosures and of course they play more/lower frequencies, but if not properly designed they have other sonic drawbacks due to bigger baffles and more complex driver systems). Of course this thread can open into more generalities but I would like a comparison between these specific Arx models.
A large sub-woofer eats all towers for breakfeast even def tech super towers.
Large floor-standers are best for 2ch listening without a Music based sub-woofer. ARX A'5s are best at this.
I guess it depends on your room size if you need Bigger A5s but I have a small room and still want to buy a pair Someday in the future.
