Not really, i reckon perspex enclosures are crap, let alone any pre-fab one. And you need to know if the internal dimensions of the enlosure are within the manafactuer's reccomendations. And being a ported box, depending on what frequency you want to run the sub at, the port wont be tuned correctly to the Type R, . I'd personally run the Type R in a sealed enclosure myself, you'll save money , the bass wil be clearer and you will run less risk of damaging the sub....
