Pyle PLBW84 Blue Wave 8" Woofer
Would this sub be well suited for a "Free air" setup
I have a 1998 firebird and i am looking to put these in the sail panels behind the front seats to utilize the low frequency coming from the factory amp.
The available specs for this woofer are limited. Based on the comments and the free air resonance of 60 Hz., I would look to put it in a vented box arrangement. Then you could hope to control that response in 40-80Hz. territory. Just a thought.

Problem with setup or just a bad speaker?
I bought this speaker to install in my 1998 Jeep Cherokee. I installed the speaker in the side of the cargo area on the passenger side of the Jeep. Behind the plastic side trim I attached a piece of sheet metal to the Jeeps structure in order to mount the speaker. Though the speaker is not in a "sealed" enclosure it's not in free air either. The front of the speaker is separated from the rear by this sheet metal panel but the entire area is not sealed. I guess it would be a lot like the trunk area of a normal car only significantly smaller.I am feeding this speaker with a 100WPC Lanzar amp.My problem is that I can barely tell this speaker is installed. If I turn up the power to it it just distorts badly. If I turn the power down to a point where it will not distort I cannot even tell it's there. From the write ups here I have to believe my setup is the problem. Does this speaker require a sealed box to keep it from over extending?The speaker cone does move a lot when playing but there is very little sound coming from it. So, is there something wrong with my setup?B
You effectively have a dipole more than a leaky "sealed" box. It will require sealing the front wave completely from the rear wave. Basically, the enclosure isnt sealed until you push on the cone and it is pretty hard to push it in. Its not sealed if you can push the cone in and it takes a while for it to spring back into place.
