DIY

I think lot of people will argue the C-note is the value kit in this price range. It's a great little speaker but for a bedroom this thing should be a contender. I would argue that it has a clearer sound at lower volumes you might use at night

Best for what?

Music, TV or Gaming or do you want it detailed or round.

Also, are you aiming at compact 4" or large 8" bookshelves....

For 300 USD you can do a lot.
