Bottom Line, if you are looking for a Woofer as a replacement for one you've blown or a new woofer for that system you are building the Mavin UNI-Z 48jp is a great choice. You get the performance, the power handling and sound quality all at a price everyone can afford.
If you know me, you know I like a deal, why spend $300.00 when you can spend one third that amount, and get something that performs just as well. With the UNI-Z I believe I've gone one better, the Mavin Uni-Z series not only looks good but it performs too.

With the UNI-Z Balance is Acheved

Note this is a very heavy speaker and will require the use of at least #12 screws and a 3/4" or greater cabinet front to secure correctly. T Nuts may be required if the speaker is mounted vertically. The speaker can pull free, it is that heavy, if your cabinet is particle board or MDF, I would use T-Nuts to prevent damage to your cabinets....

What I was looking to do with this design was to come up with a good sounding do everything all around woofer. Have done several Cerwin Vega deals over the years, I knew there was a market for replacement Cerwin Vega woofers and no supply to be had. So I modeled the drivers looks off that of the Classic Cerwin Vega or JBL style of woofer, but that is where it stops, this Woofer is right at home in a 3 ohm, 4 ohm, 8 ohm or 12 ohm environment. Power was a consideration too, I liked Cerwin Vegas [...read more]
