I am looking for suggestions on port tuning (recommended Hz) for a 18" DC Level 4XL D2 pushed by a US Amps Merlin MD2D 1500W@1ohm.
This will be going in the back of my family van and I have about 6-7cubes (maybe 8cu if I am willing to give up more trunk space) to work with.
This will never be metered. I just want to rock on out to some old school Techmaster PEB, Bass Mechanic, etc. FWIW, I like the lows
What is a good frequency to shoot for to make this sound good?
Here are the subs specs:
Mounting Depth 9.25"
Mounting Hole Diameter 16.75"
Motor Width 8.75"
VC Diameter 3" Flat 8 layer
Magnet Weight 50lbs
Power Handling RMS/Peak 1500/3000
Impedance D 1 or 2ohm
Sd 1159.00 cm²
Suggested Sealed N/A
Suggested Ported 5.0³-8.0³ ft
