Bassforms Fiberglass- For top quality bass reproduction, we recommend the fiberglass subwoofer enclosures by Bassforms.  Most Bassform fiberglass subwoofer enclosures also provide a nice mounting area for you amplifier.  It is the opinion of most users that true fiberglass sub enclosures provide the best sounding bass. 

MTX Thunderform subwoofer enclosures are famous for their sound quality.  MTX Thunderforms are available without a subwoofer, with just a subwoofer installed and also with a sub and amplifier installed.  The major benefit of the amplified Thunderform is that it includes a class D amplifier and provides a fast installation in most situations. Thunderforms are molded from a high density polyethylene resin.

Q Custom subwoofer enclosures are very similar to the MTX Thunderform in appearance being vacuum formed from a composite material but are only provided as the empty sub enclosure.

Obcon subwoofer enclosures - Obcon and R/T subwoofer enclosures are constructed of MDF.  Most models are available in vented versions also.  The combination of MDF construction and vented configuration translates into louder bass then most.  See details of their construction and decide for yourself.
