    So I was originally going to go with dual 24x24x24 subs in my setup. My wife said that just wasn't going to happen. But I was given the option of simply making a better sub than our existing one (eD A2-300). I am open to idea's and suggestions but here are the criteria: -24x24x24 max size...

    Hey all, First I would like to say that I am familiar with the short comings of both designs. Sealed subs roll off earlier but when you apply boost it is pretty much Null and Void. With Ported designs you are getting more output but below tuning the output drops sharply. So I am kinda...

    I am pretty sure this question will bring out a lot of different opinions and I appreciate all answers from those that have experience with this type of project. I am building a clone-like subwoofer system to the Wilson Audio Alexandra XLF speaker. For those that aren't familiar with it, here...

    Hi all, I have "stood down" my ambitious plans for a monster Tapped Horn for the moment. Instead I built a 24" cube sealed box for 2x 15 inch Alpine SWS-15D4 and it works ok, clunky bracing not withstanding. It is a "test mule" somebody called it, over at the Other Forum That Shall Remain...

I would like to build a slot ported box tuned to around 18hz using the driver and amp i already have. Is this possible? I'm still very new to all of this and any help would be appreciated. I was...

    So I figured I might as well start a thread for a ported cabinet build that I'm in the process for building. So a little background, I have a dedicated home theater room down in the basement that's roughly 19.5ft long, 14ft wide in the front where I have a front stage with a AT screen and...
  10. Sealed Subwoofer Build Projects
    I've read it is typically not recommended and is challenging to balance subs when you use both sealed and ported in your setup. Does this hold true? I have dual sealed UM15-22's in 4 cu. ft. enclosures, with an iNuke 3000DSP. I haven't measured them with REW yet, but I did measure them with...

    I am in need of some excellent advice from Mike P and my friends over at the "shack"? I am having a severe case of driver-selection-itis. :help: I have owned some great subs in the past ie. Danley TH50, DTS10, Dual passive Cap Pros on a PL380 QSC, Quad Soundsplinter 15 with (8) 15" AE passive...

    I folks! I'm new here and I am looking at building my first diy sub(s). The plan is to build 2 cabinets each with a single driver. So far I have read several builds and I believe I sort of know what I would like. I barely know what a lot of the technical terms are so hopefully I can get a plan...

    Hi - I have two ported subs (Dayton RSS 315hf-4) running with correction with BFD and REW. I need a subsonic filter, the crown amp I am using (xli 1500) does not have crossovers or EQ. I need a subsonic filter at around 17hz to prevent overexcursion of driver? What other options for an...
