Enclosure design for 2xHertz HX300D subs - pls any suggestion?

[DiskBengt]

Hey!

I'm about to build a box for my two Hertz HX300D subwoofers. I'd rather build a relatively large box to complement the surroundings in my trunk (station wagon). I guess that means I have to build a vented box. Although I've heard that these subwoofers sound much better in a closed box, is that true? I listen to all kinds(!) of music, but deep bass with good respond is nice. As much SQ as possible without taking too much performance away. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif They will be kicked by a DLS Ultimate A6, 1200w@1ohm.

Anyhow, anything between 2.29-3.53 cu ft (65-100 liters) would be great. What do you suggest? I also have a reflex tube (Aeroport) that is 15,5cm (6,1") in diameter and 30cm (11,8") length, can I use that, or do I need another one?

Or should I skip vented box and go with a smaller closed box?

Parameters: here

Thanks in advance!! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Random sub testing today

just a reference.. i would most likely tune to 30-32 hz if going ported and would build a basic box, with beauty panels

I got 3.5-4ft^3 tuned in the 30-32hz range. Gives you a f3 in the upper 20's and keeps the response pretty flat outside of vehicle.

Thank you guys!

rosshimself13: Seems great! It will be simple everything. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

RAM_Designs: Is that vented or sealed? If vented, what ports hould I be using?

It would be ported, you can use any type of port you'd like
