Just a note; All you guys wanting enclosure designed / built or what ever
I keep seeing all these air space or volume request with speaker size/ tuning frequencies and so-on
It is very important to know more information
like the type of vehicle and more
The environment (Vehicle) will seriously effect “ALL” these factors
An Experienced Subwoofer Enclosure Designer (not just builder)
Needs to account for All the variables

True available space
Locations and surroundings for new enclosure
Distance to the Listeners
The Acoustical Characteristics of the Environment (different vehicles and certain
locations inside of that vehicle will react differently
Power Demands
Audio Objective (Type of Music, Response and SPL Levels)
Cosmetics (Looks)
Cost (The Cost of a Custom Subwoofer Enclosure can go and be divided up in
many directions)
You can spend a lot of money on just Looks (Fiberglass, Paint, Vinyl, Plex, Neon,

ECT...)

You can spend a lot of money on Performance (SPL or Sound Quality)
It’s finding the right Balance for that particular Project

An Expensive Subwoofer and Amplifier dose Not Equal GOOD BASS

Straight cut MDF and a Box Program dose Not Equal GOOD BASS

Smaller and\or Fewer Subwoofers Done Right Will Out Perform More and\or Larger Subwoofers Done Wrong

Big and Expensive Subwoofers (W7, 9500, Power T) is Not Always More Bass

Big and Expensive Subwoofer Sound Bad in Cheap Boxes; Spend the money on the Enclosure not the Sub

well I need to know how to determine the port tuning, a well explained formula so I can make a box for the 15" btl Im about to buy

Would it be worse or bad if I make a fiberglass box and just stick the port in the middle of the box instead of up against the wall of it, I want the sub to port into the cab while its in the trunk from the back of the box through my armrest in back seat, or should i use mdf for the back and side walls and port it out that way
