Which hits harder, the BIO-10 or the RV12P?

The RV12P has the larger 12-inch driver and a tuned vented box, so it usually plays deeper and louder out of the box. The BIO-10 can match or beat it only if you put it in a good ported enclosure and feed it close to 400 W RMS.

Do I need a box for the BIO-10?

Yes. The BIO-10 is a bare driver, so budget for an enclosure; CT Sounds sells matched ported boxes. The RV12P includes its cabinet.

Which is easier to install?

The RV12P. It arrives assembled with a gold-plated push terminal, so you run power and speaker wire and set it in place. The BIO-10 needs a box, mounting, and wiring.

Is the RV12P worth the extra money?

At $99.95 versus $69.99, the RV12P is the better value for most shoppers because the price includes the cabinet. The BIO-10 only wins on cost if you already own a suitable box.

Neither has a published durability rating. The RV12P's MDF cabinet protects the driver; the BIO-10's copper voice coil and air cooling are built for long sessions, but it is only as protected as the box you give it.

What amp do I need for each?

The BIO-10 wants an amp rated near 400 W RMS at a 1-ohm or 4-ohm final load from its dual 2-ohm coils. The RV12P's single 4-ohm coil pairs with an amp rated around 300 W RMS at 4 ohms.
