BannisterEc Posted February 10, 2015 Author Report Posted February 10, 2015 That is absolutely awesome, thank you for taking the time to help. What do you mean by minium port clearance of 14cm? is that the loading space from the port to the bootlid?
Cj Kumz Posted February 10, 2015 Report Posted February 10, 2015 That is absolutely awesome, thank you for taking the time to help. What do you mean by minium port clearance of 14cm? is that the loading space from the port to the bootlid? Yes that is the minimum distance the port should have from any walls in order for it to work properly.

Joe X Posted February 10, 2015 Report Posted February 10, 2015 Yes, choking the port can cause tuning shifting and loss of output, ideally you want a little more than 14 cm, You also will need electrical system upgrades and setting your gains properly to avoid damage to your subs.
BannisterEc Posted February 11, 2015 Author Report Posted February 11, 2015 Working on another alternator at the moment. Port length is 51.8cm into the box and 42.6cm height and 14cm space between the port walls?
Joe X Posted February 11, 2015 Report Posted February 11, 2015 Yes, that's right, when you fit the front panels you already have the location where the port parts go, if these are placed correctly you should get the14 cm.
BannisterEc Posted March 9, 2015 Author Report Posted March 9, 2015 Hi Joe I am very grateful for the box you designed me below, but the guys off the South African forum say the spec sheet below will cause the subs to over excurt. I did ask them what size they recommended but no one was able to answer. Could you please help me prevent this with modifying or changing the design please even if the frequency may have to go up. Really appreciate the help!!!
Joe X Posted March 9, 2015 Report Posted March 9, 2015 The box is made to the manufacturer recommended net airspace as listed above (108 L per sub), as long as you don't go over rated power and use your subsonic filter as stated there should be no over excursion, they don't list the Xmax parameter which would be a way to verify any claims, I would recommend contacting the manufacturer and submit the design for approval, if they recommend something different I will redo it as they instruct.
BannisterEc Posted March 9, 2015 Author Report Posted March 9, 2015 I will email them now, thanks again Joe X
BannisterEc Posted March 10, 2015 Author Report Posted March 10, 2015 Hi Joe, just spoke to someone from Targa. He says that there is noway that is his specsheet so clearly that box of 108Liters is fictious. He says the subs xmax is 2cm only
Cj Kumz Posted March 10, 2015 Report Posted March 10, 2015 As long as you set you subsonic filter right I don't think you could run into excursion problems. Unless you overpowering as Joe states. With 20mm 1 way linear xmax you should be fine. Another option would be to look for people who are running the exact model and find out what their experience is with them. Other than that the a 7.6cube box looks fine to me Vw Polo Pioneer Deh-6050UB Sundown Saz-3500d DD Audio 9500 15'' 5.5 cubic feet box with 10 inch port @ 38hz I live to hear the Bass drop!!!
