Imagine your home entertainment system powered by our biggest towers of sound. Treat your ears to the 633 Concert HD. Two 633-T towers, with their tight bass, true midrange and crisp, realistic highs. The enormous sound, true vocals and clarity of the 634-VAC. Two 632-LR bookshelf speakers immersing you in multi-channel music and theatrical surround sound. The S-12 subwoofer broadcasting beautiful bass that you can feel in every bone in your body. Ahhhhh, now that’s the way to listen to music.
