  2. Down-firing subwoofer

    DIY Audio
    Hello everyone. I'm planning to build a down-firing active sub for my home theater. I have a JBL double coil car sub driver. If I connect the coils in series, the resistance is 4 ohms. Referring to T/S parameters, it looks like a good choice to make a nice sub, but it looks fairly ugly, so I...

  5. Thinking about a second sub- looking for something compact and/or downfiring

    Home Audio Subwoofers
    Currently, I have an Axiom EP-500- which is a beast of a sub. For my installation, WAF dictated an in-cabinet type installation (I'll post pics if I can figure out how on the iPad app). For movies, it didn't seem to make much of a difference. I still get room shaking low end bass. But it lost...

    Creative Sound Solutions
    I'm still struggling to come up with a project that will fit my room. I'm considering building an ottoman bench with the quartet12 kit. The trio12 and APRs would all be downfiring on the bottom of the cabinet. I didn't do the math yet but the box would be somewhere in the 16" X 16" X 36"...

    Building my first down firing box. I have a pretty hefty eD 160v.2 that I obtained when eD was clearing them out. I was wondering how best to secure it to the bottom of the box. Just screw it in as I would a front firing application? Mount from inside the box? Sandwich it in somehow? TIA

    My first DIY project was a Peerless XLS 10/12"PR in a 31L enclosure. Out of ignorance, I mounted the driver and PR on opposite sides. With about 600g of weight on the PR, when things get low and exploding, this puppy does some serious rocking.:doh: I want to rebuild it as an end table, with...
