... but with that much space, wouldn't it be possible to build some horns with something crazy like <10Hz tuning?
Yes i pretty much can fit anything but reason i choose this because its my first ever build or cutting wood. Lol trying to keep it simple and build my conference up before i tackle a horn design! And im not going for extension as much 18hz and up is fine with me for now.
this is kind of like dual marty subs in a single enclosure, BUT the enclosure is a little smaller so the low end sensitivity is a little less, but just a little. the other difference is the ports. this version employs round ports that are smaller than the slot in the marty sub. port velocity will be higher, so chuffing and compression may set in a little earlier, but it should still be ok, more or less.
