    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...

    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...

    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. 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...

    I have a dual 4ohm VC speaker. One VC measures 3.4ohm the other 7.2ohm. This does not seem right???? Bop:scratch:

    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...

    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...

    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...

    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...

    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?
