ToNasty Posted July 1, 2019 Report Share Posted July 1, 2019 I got this sub. And its what im using in my truck now. Only issue is. I dont know what net area or port area i need for it. Parts express sort of tell you but i dont really believe that. As other tell me it needs more area https://www.parts-express.com/dayton-audio-rss265ho-4-10-reference-ho-subwoofer-4-ohm--295-462 This is the sub. Will be getting rated power. I just need to know area and port area I know its not an output machine and thats not what i want. I need it to be musical Thanks again to anyone tbat can help ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted July 1, 2019 Report Share Posted July 1, 2019 I've been using that sub in my home theater setup, they are awesome subs. I'd suggest a 1.2 cu ft box tuned to 30 Hz. 17 sq in of port area, the port will have to be long.

My configuration would be center console since its a regular cab with sub firing at the back wall and port firing forward under the dash. If you underdtand what i mean This os an sq build and my midbass will br crossed somewhere in the 70-80hz region ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
ToNasty Posted July 1, 2019 Author Report Share Posted July 1, 2019 My calculations looks like my port will be about 13.5 wide and 1 3/8 tall about 40" long Might be easier to grab a second and do 2 ported on low power. Only issie is. With what im working with. 1 would have to fire backwards and 1 would have to downfire. Each would get about 400 watts at that point to ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
White Lightning Posted July 1, 2019 Report Share Posted July 1, 2019 That seems like a lot of work you may or may not be happy with. I’d build a test down fire with a long pvc port firing forwards and make tuning decisions from there ...

The issue with that is the port most likely couldn't be over 4" diameter. and I dont know what size to use but I know it would be at least 36" long ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...

If you underdtand what i mean This os an sq build and my midbass will br crossed somewhere in the 70-80hz region I don't see any issue with using a labyrinth style port like this for your particular application. There can actually be some sound quality benefits to using a labyrinth port and since you aren't going for crazy SPL I don't think you will have any issues with it. Based on the port calculator I use, a 1.375" x 13.5" will need to be 38" long to tune 1.2 cu ft to 30 hz. Its long, but not unreasonable.

I need it musical not loud. Of course I like my bass and want to hear it. But I know I have to sacrifice a little output. No I just need to find someone to model this for me. So I can get building.

It's the box height. and the port having enough room to go over the sub motor ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
