I went ahead and got some new studio speakers for my home office. These are the M-Audio BX5a. The Logitech system didn’t sound terrible (especially at normal volumes) but it was cluttery and was difficult to work with. The new system has less bass (no subwoofer) but they sound very clean and seem to perform quite well with everything that I’ve thrown at it. It’s a new experience to me because I’ve never really distinctly noticed the different between “muddy” sound and what I hear now.
Mine don’t look quite as nice — the exterior case design is a little older. But still a good buy overall.
