  1. DIY Subwoofers - General Discussion
    Im struggling to get a good box design that can place my existing sub (Dayton rss390-hf 15) in the closet and vent into the room. 4th order working within 11cf I get a peaky response between 20-40hz. Ported response is still a fantastic 20hz up and flat..But how does that then vent into the...

    As the title says, I'm wide open on recommendations on what to do with four 15" RSS390HF subs and 2 Crown XLS1000s. This will be for my HT plus I would like some clean output to minimally augment the very low end of my B&W 804s for music. But mainly these are for LFE output since the B&Ws need...
  3. Sealed Subwoofer Build Projects
    Hi, I am about to start on a subwoofer build and I'd just like to verify my sims so that I can buy an amp. I've already purchased the driver. This is a sealed 390HF in 4-4.5ft, 75% music 25% movies. I also use this system for TV viewing a lot. I want very clean bass for music and would also like...
  4. Ported Subwoofer Build Projects
    I had this sub from a tuba ht, and decided to build a new smaller box for it (9.87cu ft) with 2 4" ports that are 15.5" long. According to winisd it would have been tuned at 18.8hz and whatnot. Anyways, after about 5 minutes the sub exploded and I think it has voice coil issues, so I am...
  5. Ported Subwoofer Build Projects
    I've browsed this forum forever, but I just now finally joined and thought I would post up my project. Originally I built this transmission line enclosure for a cheap 15" sub. I havent had a chance yet to test the paremeters for this enclosure, but I think it should be somewhat universal. The...
  6. Sealed Subwoofer Build Projects
    I know this is backward, but I have an enclosure already sized at 7cf and trying to see the best path with it. I have two 15" RSS390HF plus a crown 1000. Trying to decide if it would be better to put two or one sub in that box. If one, I'll build a duplicate enclosure for the second sub. Two...
  7. Ported Subwoofer Build Projects
    After months of reading, researching, learning to use WinISD, etc etc, I finally built my first ever subwoofer (and first ever real "woodworking" project)! The basics break down like so: Dayton RSS390HF 15" driver - purchased from a fellow forum member BASH 300w plate amp from PE Box is...

    1st time playing with Unibox...here is what I am looking at. I already have an elemental design LT300 w/18 to 20 hz subsonic filter and 300w rms at 4ohms that i want to use. This sub is just for HT use. I have my Hawthorne SI's and Augies for music. I modeled a 12 ft3 enclosure, 16.4 Hz...
  9. DIY Subwoofers - General Discussion
    Hello, After reading for months:nerd:, I have decided to build a sub. At first my thoughts were to build an IB sub. But with some concerns of shaking up the roof structures :scared:, and more so after some modeling in WinISD, decided to go with ported sub (for now). Now, which driver to use? I...
  10. Sealed Subwoofer Build Projects
    As promised here are the finished photos and some listening impressions of my four Dayton RSS390HF sealed subs and the new system I put together around these speakers which I DIY'ed. Hopefully it is ok to post these photos in a separate thread from the build thread which is also on this forum...

    OK - First off thanks to anybody here who has provided me advice and to all of you who have posted your own DIY sub pics in the past. It seems that for the past 6 months or so I have spent an inordinate amount of time on this forum as well as other AV Forums and have gained an amazing amount of...

    Greetings folks newbie here. I had a converstion with Parts Express on telephone and by email and got 2 different answers regarding the Dayton 15" RSS390! I am looking at an old 340 liter sealed box that housed an Adire Tempest 15". I looked at the response on winsd which looked good for my...
  13. DIY Subwoofers - General Discussion
    At the moment, I have a pair of Dayton DVC385-88 15" drivers that I'm using in a 6.3cf sealed push-pull configuration. I've looked at the 15" Titanic MkIII and ran the numbers though WinISD Pro, but these drivers don't offer anything better over what I already have. In fact, they are just about...
