Hello,

I need help with figuring out the correct enclosure size. I got a Orion HCCA 10.4 sub. Right now I have it in a small sealed box built to Orion spec, but the sound quality and spl is not very good. Sound quality is my main focus, but having some spl is nice also. Right now it does not sound very loud. I read somewhere that the HCCA is not good in a sealed box, so I am trying to figure out what is the best ported box for it. I am putting this in my car so I would like it as small as possible. Later on I might use it for HT.

I downloaded WinISD Pro and try to get the enclosure spec for this sub. But I am getting errors and I am not sure what to do. Since I am a total noob, if someone can help me out I will greatly appreciate this. THANK YOU!!!

Here is the spec for the sub from Orion:

Are there any ported recommendations on the Orion site?

Well the manual recommend 1.2 cu ft for vented box. Tune to 38HZ with port size 3"x3" square and 12" length. Does that sound right?

 

[Mike P.]

For car audio I imagine Orion would recommend what the best size and tuning would be. As for sound quality and SPL, what are you powering it with?

Hey Mike,

Thanks for help so far. I am running a JL 500/1 to it rated at 500w rms @ 1 to 4 ohms. I got the sub wired at 2 ohms. What do you think of those ported box they sell on Ebay? They look like they are nicely built, but none of them list what they are tuned to and size of the port.

Thanks!

 

[Mike P.]

You can ask the seller what the size of the port is and the tuning. If they can't tell you then don't buy it.

Jody, if you ll give me a model of driver and it's parameters in the european measurement system (millimeters, liters, kilograms etc) i will be able to help you

Thanks for the offer, but those numbers are the only one I got.
