brand new o the forums, and looking for help with designs for some subwoofer cabinets. i have built dozens of if not into the hundreds of car audio subwoofer systems over the years but i have some questions about a completely different application. i am quoting on a sound system for a church renovation and they are interested in putting the subwoofers under the stage. they only gave me 14" inches of height and 20" inches of width....but no depth issues. i was looking at the eminance 12" drivers , and designing something that will slide under the stage. i was thinking four of them running off of 1000 watt qsc amplifier. Has anyone ever done this? and what do i need to be aware of...this isnt the trunk of a car.
What are the needs in terms of output SPL and freq response?
You HAVE to have a design goal in mind before starting any design.
Since you already know most of your physical limitations and available power that is a good start.
However you said a "1000watt QSC amp". What exactly does that mean?
Do you have a model number? Is that a single channel or total of 2 channels? At what impedance does it deliver 1000 watts?
This helps in determining how many drivers you can run and the power capacity of the drivers.
