Thank you for your input.
I did a little looking today ,and found a Car Audio shop that would build me an 8cuft enclosure with a slot port tuned to 18hz,for 200.00. Im kind of looking forward to doing it myself,but after materials,i dont know if i CAN build it any cheaper than that. Of course i'm assuming that they would do it correctly,whereas if I do it,i know i'll take my time and do it right.
As far as the actual shape of the enclosure,i remeasured and i'm leaning toward making it around 13" tall ,so i can make it a touch shorter. 13x24x48" (approx 8.66 cuft)
1. How does that model as far as the 4" PVC for a port vs a slotted port?
2. Also,if i go down firing,is there a benefit (or loss) by adding a "platform" for the sub to fire towards vs firing into the carpet?
Thanks for your input!
