[QUOTE="Aygodriver1212, post: 8492593, member: 669550"] Hello guys, I figured I'd make a new thread since the old one was just bumping the entire time and it went off topic. With some help I chose for this subwoofer: [URL="http://www.ground-zero-audio.com/en/products/subwooferchassis/gztw-30tx.html"]GZTW 30TX[/URL] If you have a better sub to recommend at a price range of around 100 to 150 euro's please do recommend it first. The T/S parameters of my current choice are right here; [URL="http://www.ground-zero-audio.com/components/com_jshopping/files/demo_products/GZTW_TX_19042010_GZTW_38TX.pdf"]http://www.ground-zero-audio.com/components/com_jshopping/files/demo_products/GZTW_TX_19042010_GZTW_38TX.pdf[/URL] [URL="http://www.ground-zero-audio.com/components/com_jshopping/files/demo_products/GZTW_30TX.pdf"]http://www.ground-zero-audio.com/components/com_jshopping/files/demo_products/GZTW_30TX.pdf[/URL] I want to create a ported enclosure, bass-reflex pipe port preferred (I have a few ones available you can find them down in the thread). As my name says, I have an Aygo. So I have limited space. I took a new look at my trunk and re-measured. Seems I can fit a wedged shape box with these max outer dimensions. I think the width should be a variable since that's the biggest value here and the easiest to alter. I'm planning on using 18mm MDF, in inches that's about 0.7" I believe. [IMG]http://www2.pic-upload.de/img/30249414/maxininches2.png[/IMG] Can anybody help me calculate a box or even calculate one for me? I'm looking to tune it to about 32 hz since I listen to a lot of hip-hop. Different port sizes I have available right now are: [I]Ø 2" - adjustable length: min 5.9" - max 11"[/I] [I]Ø 2.5" - max length: 7.5"[/I] [I]Ø 2.6" - adjustable length: min 5" - max 9.6"[/I] [I]Ø 2.95" - max length: 4.7"[/I] [I]Ø 4" - max length: 4.5"[/I] Of course I wish to reduce port noise as much as possible. Again, I've tried WinISD and it's just not working out for me. No clue what I'm doing wrong... I HOPE you can help me. Thanks! [/QUOTE]
