A PR acts like a port, without needing a port. You still need the same net volume as a ported box setup, but you don't need a port so you save space that way. PR's are generally best for situations where a small box and low tuning are needed, which would call for a very long slot port...a lot of TC woofers fit this description, hence why they made their own PR's to match with their woofers.
