well spl isnt supposed to sound good lol wat is the resonant frequency of the hhr? lol

 

haha, I know, but thats why I stick with my current box that only does 153s. It sounds really good.

Frequency depends on sub and port position. With my subs up, ports back position my peak ranges from 38hz to 47hz depending on temperature and humidity and how far I position the port from the back hatch.

My best score has been done at 42hz in 48 deg F overcast and slightly rainy weather.

 

ya, when i hit 147.8 with 2 12' in the back, facing back and ported back it was about 42-45
