Recommended enclosure:
SQ - Bassreflex 45l (port area at least 90cm2)

Relatively cheap woofer, which offers quite a lot for the price. Ideal when you want high performance for small amount of money. Suitable for both bass-reflex and sealed enclosure, in this price range better than almost anything.
