Enclosure for Obsidian 12 on low power
mikebingham34 posted a topic in SPL & SQ / FabricationSo I will be ordering an OA-12v2 D4 very soon after selling my current system (Upgrading from a Fosgate Punch P2 12, 2011 model). I have a Rockford Prime P500-1d to work with, so the sub will see just over 500 watts. I have read in many places that the more power, the smaller that the box can be, and the less power, the larger you can build the box... generally. So I was thinking of doing a 2.5 cuft enclosure for the OA, on the 500w. It will be going in the trunk of my 2000 Civic sedan, most likely sub back, port side. Does this sound appropriate? Is there another way I should approach this? The box will be tuned to 30Hz via 4" aeroport. Thank you for any help, and I apologize if I left out any important details.
ported Sundown E-12 tuning
mikebingham34 posted a topic in SPL & SQ / FabricationHey, I am looking to build an enclosure for one Sundown E-12 in the near future. I plan on putting it into a 2.5 cubic foot enclosure. (PWK recommends an enclosure for the E-12 of at least 60L (~2.1 cu ft) for a more linear response) I also want to use a 4" aeroport (precision port) 10.25 inches long for a tuning of 32 Hz. I think my question is, would it be alright to tune this box to 30 Hz? All it would require is 12 of port length compared to the ten and a quarter. I'm just slightly confused because I have heard not to tune too far below a subs res. freq. because it might cause roll-off right at the tuning. If it sounds stupid, that's because I read it once somewhere on a forum haha. The E-12 has an Fs of ~35.8 Hz. If anyone is wondering what this setup will be used for/what is expected of it is... a daily setup, that will hammer lows. Sure I want to get as loud as I can doing this, but I have zero concern for numbers (db). It will be fed 500w from a RF prime 500.1. If there are any other things I forgot to mention that might help in determining if I should tune lower, please let me know. Thanks for the help.
