aren't these designed for peaky output? like a small range of frequencies, but loud?

Subwoofers in general have a small range of frequencies.

Most ported subs in cars have peaky outputs.

A properly designed bandpass box can peak loudly or cover many octaves. Depends on the design.

Have to search for answers because now days the forum is full of members just adding smart azz coments. Search and look at post back around 2003-04 where members where helpful.

A good alignment mostly depends on the vehicle and how well the enclosure is implemented with the vehicle's interior. You might have an enclosure that pegs the meter with car "A" but does very little in car "B" with the same power.

I have some question with some things that came up.

Like what are they, and how do I find them.

Xmax = maximum linear displacement (mm)Dia = Effective diameter of driver (cm)

Qts = driver Q at system resonance

Ql = box losses (Ql=infinite (10000) can

be assumed for most cases)

Vas = equivalent air compliance (litres)
