Hi DIYers
I hope you can help. I am building a pair of passive subs for my rock covers band to reinforce the active LD 10“ G3 stingers I have.I am on a budget so please don’t judge too harshly. I can’t justify the cost of 2 active subs. Nearly $2k per side here in Australia!
I already had a decent spare power amp so I bought myself 2 x Faital Pro 15PR400 drivers and a couple of sheets of 18mm MDF for the enclosures.
The external dimensions are 610mm wide, 600 deep and 500 high. I opted for 15” drivers on the basis of total enclosure weight and transportability.
The front panel looks a bit busy with the driver plus 2x 75mm dia ports which I have and was planning on using and they look to be too close to the edges of the enclosure.
Q1 - Am I better converting the design to a front rectangular slotted port or shall I just reposition the ports to the side face?
Q2 - Will the choice of slotted port vs round ports make any difference to the performance?
Thanks in advance for any advice.

Would 2x 75mm ports be to small for an 18" driver?
Just plugged the specs into WinIsd with 150lt box/2x 75mm ports@40Hz tuning you would be hitting 17ms velocity at only 30 watts(rule of thumb threshold), give it 100w it'll be chuffing over 30ms
