    a group of guys in my town think playing low as possible is the best way to build boxes, its so stupid they can play down to like 10hz but the box rolls off at like 25hz so there is like no loud bass above 25hz... When I build my boxes I want them to be loud and musical and have a good frequency bandwidth 😊

      Tune to the low 30's and you'll be good 💯

    3:10 there's definitely information on a lot of songs below 30hz, i've seen a lot of newer songs hit 20-25hz lows only thing is if you tune low like that you need something to fill the gap in the frequency response

      @@RobotUnderground I mean I guess that's your opinion. It's definitely worth it to me I have a system tuned low and a system tuned at around 34hz, the low tuned one sounds better to me it's just a hell of a lot more power and effort to get it sounding good. but ima just say this. subsonic filters make hip hop music objectively worse. If you can hit the lows then always hit the lows

      They split. Their builder, David Moore went back home to Star, MS and started PSI / Pink Star Industries. Scott sold his half to US Amps and went next door to start Fi Car Audio. US Amps and Mark I assume, still work together today. Mark has China hookups so he may have moved there to coordinate shipments and design work... as well as live a much more lavish lifestyle.

    I have tried to tune 2.0 cu-ft net vol enclosure to 33hz using 16 sq-in per cu-ft and it was impossible to get that 33hz tuning using 16 sq-in per cu-ft because the port length was going over 35'' inside the box. Ended up using 12 sq-in per cu-ft the results was good and no port noise.

    So what I’ve done and worked well when messing around with ports is on the port long wall is cut it diagonally making the low side the end away from the corner. I call it an Angled slot port just know that let’s say you wanted 10 inch normal on that side of port wall I’d make it 20 inches long with the diagonal angle. This makes the frequency range the sub hits hard in larger imo.

Formers on those subs third generation. It would help me tremendously. I have them on Facebook marketplace but I don't wanna sell them to no one if they're falling apart. And is there any way I could fix it maybe with? Some cigarettes on the exposed former. I can see maybe I don't know.
