  1. Passive to Active Subwoofer convertor for Denon AVR 2312ci

    Home Theater System Recommendations
    I recently upgraded my AV Receiver to a Denon AVR 2312ci I found at a thrift store for $30! It works very well! The only problem is my old receiver used a passive subwoofer and my new (to me) Denon uses an active port. I was reading that I needed an amplifier to use my passive subwoofer. I found...

  4. Cube Cubed - a Passive Radiator Subwoofer Build

    Ported Subwoofer Build Projects
    I have always loved passive radiators, so I thought I would finally do a build log along with all the parts needed. Thanks to Parts Express, I am able to bring one of these Passive Radiator Builds to life. My goal was to make a small subwoofer that would still have high spl, for a smaller room...

    AV Home Theater
    :wave:Hi, I apologize, but I'm not sure which forum I need to park this, since I need help determining if I can find a cheaper alternative, to the high cost of cable and satellite, by converting to an OVER THE AIR Antenna. Do you have a special forum for this? QUESTION: Is there a way to...

  8. Connect passive sub to 2.0 receiver using plate amp

    System Setup and Connection
    Hi, I'm looking at building a DIY sub (lilwrecker) and not sure if I would take a plate amp (quite expensive and not a good option as I will need to build an external box for it anyway) or a PA amp (Behringer EP4000 or Crown XLS) I only don't really see how to connect the PA amp to my receiver...
  9. Passive preamp two channel system setup

    System Setup and Connection
    Hello, I'm going to try out a two channel system with a passive preamp and a 2 channel speaker amp. I normally use my sb12-nsd with an onkyo 7.2 receiver. The passive preamp is just a stepped attenuator knob and 1 rca input, and dual rca output, intended for bi-amping. I was wondering if it...

  11. Component car audio speakers (passive xover) be wired in series?

    DIY Audio
    My roommate absolutely loves my way too bright car audio mids/tweets. For a home audio (gaming/music) system would it be possible to wire 3 speakers / 3 tweets into a single channel to get them from the 2ohm load they are to a 6ohm (so the receiver doesn't have a heart attack)? In my mind it...
  12. Generating .frd and .zma files from REW that can be used by Passive Crossover Designer and WinPCD

    REW Forum
    To use Passive Crossover Designer (or the Windows version, WinPCD) requires that you import the speaker frequency response as an .frd file or the impedance curve as a .zma file. The instructions for REW explain how to export your measurements as text files and state that the format is compatible...
  13. Building a new enclosure for a peerless xls10 with matching passive radiator (400gm)

    DIY Subwoofers - General Discussion
    This is my first time posting, although I've been a long time reader of the forums. I am rebuilding this sub in a new enclosure, with a new amp, since I did such a cheapo job last time I built it. I had basically just thrown it in an old Velodyne enclosure that was made for an 8 inch sub with...
  14. Using passive and active crossover at the same time.

    System Setup and Connection
    I recently went out with a friend I haven't seen in a long time. he picked me up, and was proudly describing his car audio system to me. What really threw a monkey wrench into my understanding of electronics and audio was that, by recommendation from an audio expert, he is using an active...
  15. SI 18 Passive Radiator

    DIY Subwoofers - General Discussion
    Hello everybody, I am curious about passive radiators and would love to try a build sometime. I modeled a SI 18 with two PSI passives in 10 CUFT feet. My question is the PSI site lists two values for xmax, 65 mm and 32 mm total, which one should I use to model? I have attached a WinISD file...

    Salk/Rythmik 15 With Dual 15" Passive Radiators By Jim Wilson (theJman) The Salk/Rythmik 15 With Dual 15" Passive Radiators (SSR15) is an awful lot of subwoofer for the money, and I mean that in every sense of the word. About the size of a mini-refrigerator, and weighing approximately what...

    System Setup and Connection
    I'm set on buying a pair of 10 inch Monoprice passive in-wall subs and I'm not sure if I could use my old receiver as a dedicated amp for them. Here's how I understand it but I'm not sure if it will work or if there's not a more suited solution as I have never done this before. So I would be...
