The Carver Amazing Plats are in the House

Pepe!

Have you added some weight like sandbags or heavy blocks to the base to hold the flimsy frame steady and anchored down?

   Sounded good but not enough power.  We then connected the Sunfire 400x5 and they woke up (800 watts [4 ohm] times 4 will wake up any speaker).   

The Plats are 8 ohm.

Yep, that helps a lot. Before you do, make sure the screws holding the bottom plate to the panel are tight. I actually increased the screw size for better holding power.

@F1 - we removed the original Plat x-over from the the circuit.  An active cross-over is handling the frequency split.  As I understand,  the load the amps are seeing is now 4 ohms - that is what the experts tell me.   Do you know different?

He's assuming they are stock.  Your's are 4ohm.

These have no factory x overs connected up.

Listen to what your uncle Jesse says.  Bo and Luke are driving over there now in the 'ole General Lee!

The sand bags and titanium brace with heavy duty screws advice from Dr. Jesse will not be ignored.  A flight plan for a trip to Ace Hardware has already been filed w FAA for Saturday to secure the materials. I may replace the sand bag idea with weights from my seldom-used free-weight set.  The baffle definitely flexes too much as-is if you touch the top of the speakers.  Four woofers trying to move the air in front of them in an open-baffle design generate enough thrust to benefit from better bracing.  The bass is tight as-is, however,  in defense of uncle Bob's design.

 

PS:  Rev - You rule.  I would be an idiot not to buy those.

Iron plates work well!  The more the better!

Ah, I didn't know you are using active crossovers. Carry on.

bags of lead shot also work well

Absolutely fantastic Pepe. Way to go Sir. I'm impressed to say the least.--------Bill

I always felt Plat's needed struts from the base to 3/4 way up on the panels. Like moly tubing with Heim joints. Very nice Pepe! I had some Silvers once upon a time. High marks on the active.
