  1. Impedence measurement issues

    REW Forum
    Okay Im getting a funny curve whereby the impedance takes a dive after 10khz rather than rising as is normal. Im getting the message " not enough high frequency data" when I try to generate TS parameters. I'm measuring an 8" midwoofer and the sweep is running from 0HZ to 20000HZ. I believe im...
  2. First Impedence test

    REW Forum
    So my behringer uac 222 came today. I made a impedence rig from a tutorial i found at avs by lil mike.Links at bottom. I have been at this for 4 hours and have an impedence graph but it doesnt look anything like i think it should.Could someone with experience please tell me what they think of it...
  3. multi room speaker setup help

    System Setup and Connection
    Hi all, Firstly please excuse my obvious lack of knowledge as I am still very uneducated in the world of audio... Anyway, I am looking for some advice in setting up a three room sound system with a reciever in the middle room and a pair of speakers in each of the three rooms (three pairs...
  4. Impedence Question

    System Setup and Connection
    Hi folks - I'm a novice at this, so please excuse this simplistic question. I have a DIY subwoofer that contains a DVC driver. Its amplifier is a Dayton SA100 plate amp with 75 Watts @ 8ohms and 100 Watts @ 4ohms. I am going to connect it to my Onkyo TX-SR608 AVR. I would like to parallel the...
  5. Voice coil impedence

    DIY Speakers
    I have a dual 4ohm VC speaker. One VC measures 3.4ohm the other 7.2ohm. This does not seem right???? Bop:scratch:
  6. Help! driver replacement, DVC Impedence ??, and recommendations

    DIY Subwoofers - General Discussion
    Help me, Obi-Wan Kenobi, you're my only hope. I'm looking to replace a driver I damaged, I'm willing to downgrade somewhat (unemployment), but want to keep my existing sub cabinet since it has acceptable SAF. I've been running an old Stryke (now AESpeakers) AV-12 in a DIY 3.4 cubic ft box tuned...
  7. Speaker Impedence

    DIY Speakers
    Still messing with this design. WMTMW in a 3 way parallel XO. After running everything parallel I'm getting a system impedence of 2 or less Ohm. Is there a way to raise the system impedence to at least 4 Ohm? I want to run the WW and MM parallel to get the 6db increase that helps match the...
  8. Mixing Speaker Impedence

    Home Theater Receivers | Processors | Amps
    I am shopping for some replacement speakers and had a question about speaker impedence. I have a Denon AVR-1910 receiver and I am looking at the Axiom M60 floorstanding, VP150 center, and QS8 surround speakers which are rated at 8, 6, and 6 ohms, respectively. Is mixing speaker impedence like...
  9. 3 way with differing impedence drivers

    DIY Speakers
    I'm thinking of designing a new 3 way speaker. A WMT, where the efficiency of the Woofer is 91 dB , the mid is 88 dB Tweeter is 91dB To get the Mid up to 91 dB I thought i could use 2 mid-range drivers. However this would mean that the mid section is 4 ohms and not 8. Can sombody explain...
  10. easiest way to test driver impedence?

    DIY Speakers
    Im in the process of getting myself set up. I just received my ecm8000, I installed my new sound card (sound blaster live), and Im waiting for my preamp. Can I begin testing driver impedance w/out my preamp, and if so whats the best/most efficient way to do this?
