I recently purchased the LSi9 book shelf speakers to complement my home theatre surround system. I have an Onkyo trx80 receiver that I just recently purchased. I have to say I'm somewhat disappointed in the speakers performance. For the amount of money I spent the midrange is surprisingly absent. The speakers have nothing functionaly wrong with them but again they are less than impressive. My subwoofer functions fine, but any guitar or midrange frequencies sound weak. Has anyone else experienced this.
