Colin - STAPUFT Posted November 13, 2013 Report Share Posted November 13, 2013 In an enclosure that is geared more towards SQ, what is the best alignment for the Sub and Port? I would think sub and port on the same part of the box, but it may not make a bit of difference given the application. I just wanted to know what you guys think and have seen. ***And yes, I know lots of "SQ" builds use sealed enclosures. No- this is not going to be that kind of build. It is for the wife's 5.1 setup in her Trailblazer. I am looking to put my Tang-Band woofers in the doors that will play solidly down to about 55 hz, and then run the subs for the low low. Hopefully about 25 hz tune or so.*** Thanks all- 12 - 12"s in the STAY PUFT 1989 Chevy Astro Build & Comment Log Un-Interrupted Build LogYouTube Channel Chevy Trailblazer 5.1 Dolby Digital DTS Install You have a beard of a mysterious sea captain.

Triticum Agricolam Posted November 13, 2013 Report Share Posted November 13, 2013 It doesn't make a huge difference but having the port mouth a close to the drivers as possible will help the output from each blend together better. Also if you build the box on the smaller side of things it will result in a flatter response curve and less group delay.

If you go big or stupid big with the box, output jumps way up and low end extension can go buck wild, but it has the tendency to get peaky and bloated. I had a box like that for 4 12"s once. Stupid low, but didn't play very "fast" and not too accurate. Fun for a minute though. ;D Smaller looses a bit of output, but it is worth it for accuracy.

bbeljefe Posted November 14, 2013 Report Share Posted November 14, 2013 If you have room for it, put the sub in a transmission line. Nothing's gonna match the sound quality you can get from a line.

Nothing's gonna match the sound quality you can get from a line. That's a good suggestion. I've always been tempted to build a TL. I don't think space would permit in this application though. There is plenty of room there, but this has to be a properly functional vehicle. I would be surprised if I am "allowed" to get away with as much room as I am likely to take up anyway. Plus, I am going to be using 2 12"s. Unless I did an Isobaric TL, I don't think it is in the cards.... 12 - 12"s in the STAY PUFT 1989 Chevy Astro Build & Comment Log Un-Interrupted Build LogYouTube Channel Chevy Trailblazer 5.1 Dolby Digital DTS Install You have a beard of a mysterious sea captain.

Isn't quality bass a base function of a vehicle?

Colin - STAPUFT Posted November 15, 2013 Author Report Share Posted November 15, 2013 True. Bass is indeed a necessity. I know one proper 10 would do well enough. But I want on the verge of too much. Plus- I don't have a 10. But I have plenty of 12"s laying around. 12 - 12"s in the STAY PUFT 1989 Chevy Astro Build & Comment Log Un-Interrupted Build LogYouTube Channel Chevy Trailblazer 5.1 Dolby Digital DTS Install You have a beard of a mysterious sea captain.

kirill007 Posted November 15, 2013 Report Share Posted November 15, 2013 Don't forget using more then enough port area. Putting the port right next to the driver will be good enough for a good sounding setup. If you want to get the maximum out of it, you will need to play around with the port placement. EDIT: the port placement cablguy suggested looks pretty good if that's the car. Thinking is the root of all problems... You ALWAYS get what you pay for.

But I have plenty of 12"s laying around. as long as you have time alignment for the sub stage, and a good flat response ported and tuned enclosure you should be good as long as those 12s are musical and not SPL monsters ... ... or at least give you plenty of room for trail and error Kenwood / HELIX / Linear Power (For The Love Of Music) / Brutal Sounds / OverKill Electric Co Questions About Sound Quality ??
