Hi, Im still a novice at car audio and wanted some help. I built a transmission line box for an HDS208 8" woofer.
I did some researching and found some information about setting subsonic filters. For ported boxes, I read, you should set the subsonic at half an octave below tuning frequency of the box.
I also read some information about transmission lines that said they are supposed to have great bandwidth and efficiency such that the output of the box, a whole octave below the tuning frequency, will be just as powerful as the tuning frequency in a lot of cases.
That said, should I be worrying about a subsonic filter? The amplifier I'm planning to get does not have one. I want to get a Rockford Fosgate R500x1D. Amazon Link
Any input would be much appreciated //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
