This 4th order bandpass will be going in the bed of a 2008 single cab Chevy. Inside will be two of the new model Orion HCCA 15's. Each sealed chamber is 2.25ft^3 with a common 10ft^3 ported chamber tuned to 46hz. As you can see, there is a removable panel at the top of the box to access the subs, and the port is removable as well so that tunings and port size can be altered to custom tune the box.

this guy is local to me.. he kept arguing with me.. he insisted that his box is sealed... while i on the other hand tried to explain to him that you have designed him a 4th order

either way i recommended you for the job
