View Full Version : final question before i start my sub box probably an easy question for you guys

i am going to build a 3.5 cubic foot box at 30hz listed in the free box plans going to use a Orion HCCA122 sub and Orion HCCA5000.1D amp or possibly a Orion XTR3700.1D cant decide. going to run this sub at 1ohm
going with 30hz because i don't like hearing tones from the sub just chest crushing bass super low freq might even lengthen the port a bit for lower like 28hz i have amazing mid bass from my speakers
boy did i make a mistake buying 2 10" alpine type r

but my question is in the specs they recommend mounting the sub facing up but with the port facing the front side will this screw up the tuning does the driver have to face the same way as the port?

thanks guys sure have learned a lot here
just had to figure out why i hatted the sound of these brand new type r subs
and why i thought my old ultimate 10 sounded way better at less wattage

In theory the orientation of the sub and port on the box should make little difference, in practice, optimal position of each varies greatly depending on the acoustics of the car.

What sort of listening material do you think you need 28hz tuning to reproduce?

listen to a lot of dubstep electronic stuff a bit of rap and rock

It's going to vary greatly depending on the vehicle you're putting it in. A lot of trunk cars are louder with rear facing sub/port because of the reflections off the rear of the trunk. In practicality you won't notice that much difference so just build/install it whatever way makes most sense for the space you're using. If you were going to be competing and chasing 10ths then I would say put more thought into it or perhaps do some testing.

Also, tuning high is for feg's, go for your low tuning OP, that's the only way to do it IMO. ;)
