*I didn't say they failed. I said they held up fine, overpowered, for the 6 months I was using them. I just got the G5 and GTR, that's why I took out the Comp 10's. Thanks, though.

you can set up any sub to downward fire as long as there's enough room for the sub to reach its maximum excursion without hitting the floor

Ummm... yeah, NO! bad sqsq... BAD! No, you cannot use ANY woofer in a downfiring situation, and this specific driver is NOT suitable for downfiring. It is 10% "saggy", and it WILL bang the stops, (at least the front stop...) and possibly fail significantly sooner than it should. At a very minimum, it'll NOT run linearly, and sound worse than RF woofers already do/can...

Yeah i do not know any of those variables for that formula, hahaha. I went to the site and i could not find them so...... Thank you anyway. I think is going to be fine.

:::::EDIT:::::
Wait a second... You chose that woofer because you didn't have space for a deeper woofer, but NOW you want to fire it down, and take up a HUGE footprint? Something doesn't make sense with this situation... Why don't you tell us EXACTLY what you have in mind, with car and everything, and maybe we can keep you from getting into a situation that you will not be happy with...

I am instaling it in a nissan frontier extended cab. I am trying to get as stealthy as posible. The box I am building will replace the bottom part seat of the rear jumper seat in the cab. Thats why I want it to downfire. I don't understand why some people used the formula to help me and say it's good for this firing position and you and others say no.

I did not start this threat to get in arguments about donwfiring, only to get help.

Thank you.
