this product be great ! I would call it a `` passive surround sound system '' since it be perfect for background sound -lrb- while read a book or have a chat -rrb- that will not annoy you due to too much subwoofer power . it be not recommend as a audio system for dance party since it be really design for tv surround sound and background music only . the subwoofer be not that intensive but very pleasant since it do not shake up you furniture . you can leave the system on even when you be watch news channel without get annoy by too much and intensive sound .
