My uncle has 2 of those subs...but arent the XLC version just regular punch...what are the specs on the 12inch model...

He will give them to me for free...i want to put them in a vented enclosure...so if u have specs or recommended specs...that would help as well

Thanks!

RF made several different 'Punch' models back then... if you could get the model number off the back of the magnet it would really help.

4 ohm....punch....

not he...dvc....or xlc...just the base punch model 12inches 4 ohm

If it isn't the DVC or XLC, then it pretty much has to be the Punch Z... but without a model number, it's impossible to know for sure. Here are the specs for the 12" 4-ohm Punch Z's, but it would be wise to check the backs of the subs for a model number to verify...

It says punch on the middle of the speaker...so im pretty sure its the Punch Model....

But whats the wattage on the sub u gave me specs for....it doesnt have a wattage rating(peak and a rms)

Since 'peak' and 'max' specs are worthless, you can assume that the power handling (Pe) is RMS.

If there is not a 'Z' under the PUNCH on the cone, then it probably is not a Punch Z.

So really, without pulling the woofer out of the box and getting a model number, it's impossible to know which model it is... RF changed models frequently.

Thanks...

How do you think the output would be on those in a vented box tuned to 33hz.. giving them 150 watts a piece?
