TN1220 TN1220HO or 1225??

[obscurities]

I have three subs and a 500 watt amp. I am looking for a way to determine the model number of the tube subs I have. I want to run a pair and sell one.....

Two of them have a cone which seems rough to the feel if you slide your finger across it.... the cone on the other one is smoother to the touch. There is no model number on any of them.

How would I determine which subs they are? Is there a model number inside if I remove the driver, or can I tell from the driver if I remove it.

Thanks, Craig

Hi Craig,

Those may just be different driver iterations, not necessarily indicative of different model numbers.

The TN1220HO cylinder is 12" in diameter, and about four feet tall. The TN1225HO cylinder is 12" in diameter, and about three feet tall.

Sincerely,
