Cashdollar2009 Posted March 24, 2011 Report Share Posted March 24, 2011 Well i've been entertaining ideas and throwing some thoughts around until I can get my money right. Basically I have narrowed my options down to a few. Here are the two that I am on now: Two 12" or 15" DC XL's in a ported box tuned to 32Hz on a DC 5k. or Four 12" or 10" DC Level 3's in a 4th order bandpass on a DC 5k. I already have the amplifier and have just sold my 15" XL locally. I put 12" or 15" and 12" or 10" depending on what I can fit with the room that I have. The original plan was a pair of 12" XL's, but in order to get the proper enclosure I would be VERY VERY close to building in my trunk, so if i'd build in the trunk I might as well go with 15"s, depending on if I can find a place for my batteries or not. Both setups would be sealed off into the cabin and I am working with a little over 6 ft^3 if I build in the trunk. I am hoping to have enough power to possibly compensate for any lack of space. My goals are basically the generic sql answer you see. I seriously want to nail 28-30Hz, but still be able to see a high 140's on the meter. Thanks for your thoughts and opinions guys. I have yet to play with bandpass enclosures so I would be seeking help for a design from one of the experts on here, so just answer assuming that the box will be designed properly.

hdorre Posted March 24, 2011 Report Share Posted March 24, 2011 Where does your car peak? If its high (40+Hz), bandpass would probably be the better option for you.

I have honestly yet to figure that out. My first time metering I was tuned at 34Hz and peaked at 41Hz. Second time I was tuned to 32Hz with an aero and peaked at 36-37Hz. BeAlsTar I think is how it's spelled? Has a Grand Am which is the brother/sister car of my Alero and I believe he was peaking around 42Hz tuned at 36Hz?

iKidwell Posted March 24, 2011 Report Share Posted March 24, 2011 You won't have room for a bandpass with 4 12's in there unless you wall.... Quote c'mon now, if i was shooting an 8 year old, it wouldnt be MY 8 year old. i recently got a Pyle PL1590BL and i was building an enclosure for it tuned to 25 hz. i didn't have any tools to cut a circle so i hit it with a big hammer. 2003 Infiniti G35 Sport Sedan Build in Progress Link to comment Share on other sites More sharing options...
dwright27 Posted March 24, 2011 Report Share Posted March 24, 2011 That probably where your box was peaking at.

That probably where your box was peaking at. That was my peak frequency on the meter. I am still unsure of the cabin resonance off the top of my head.

Cashdollar2009 Posted March 24, 2011 Author Report Share Posted March 24, 2011 And I will say right now that a wall is out of the question. Quote On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free. Electrical energy is not. Link to comment Share on other sites More sharing options...

Cashdollar2009 Posted March 25, 2011 Author Report Share Posted March 25, 2011 Hmmm... Yeah. What do you guys think of two 12" XL's in a 4th order? On my DC 5k do you think I may be able to get more low-end output from this option than two 12" XL's or 15" XL's in regular ported boxes?
