I bought these for my media room but went a different route. These are professionally made custom speakers, cabinets appear to be 3/4" MDF with a black finish. The towers are 4 foot tall, 3-way and really striking with black acrylic fronts that look like glass. I pulled the 5.5" drivers but was unable to identify them except that they are made in the USA. The bookshelf speakers have Rockford Fosgate 'the punch' drivers but I haven't pulled the tweeters to identify them. Tower speakers: 48" X 8" X 12" Bookshelves: 12" X 8" X 9" I would consider selling the pairs separately. I have too much audio equipment and need to get rid of some. See my other adds. Call/text or email to listen to them.
