    Vortex Speaker Kit Information
    For more information and history about the Hyperlite™ coaxials used in the Vortex please click this link.

    Note on the lower introductory price: I put money towards tooling some of the custom parts on the Hyperlite coaxials about a year ago. Normally the product would have to sell at a set price to recover the tooling costs over time. But I'm not going to worry about recovering those costs until the second or third run of coaxials from Eminence. Doing that will allow the first run of kits to be sold at a lower cost. The price will have to go up after the first run of coaxials is sold out.

    Vortex-12

    Speaker Designer: Matt Grant. Matt also helped a lot by evaluating and testing different coaxial prototypes and also helped make decisions on which samples would be finalized.

    Intended Use: These are high end speaker kits that can be used full range for music in the larger cabinet designs, or high end home theater speaker kits that will play down to 55hz in smaller ported cabinets.

    Components Used: Denovo Hyperlite CX12-8 coaxial and Celestion CDX1-1731 compression driver.

    Specifications:
    • 8 Ohm
    • 96db - 2.83v/1m
    • Up to 500 watts power handling
    • 40hz - 20khz in a ported 3.5cuft cabinet tuned to XXhz with two 3" ports
    • 55hz - 20khz in a ported 2.5cuft cabinet tuned to XXhz with four 2" ports

    Important Design Details: When used for movie watching you will always need to pair the speakers with a subwoofer that can handle the lower bass frequencies. I would recommend at least two powerful 15" subwoofers to pair with the Vortex-12 speakers.

    Off axis measurement (0-90 degrees 10 degree increment) Measurement is gated so resolution below 400hz is lost:

    Intended Use:

    Components Used: Denovo Hyperlite CX15-8 coaxial and Celestion CDX1-1731 compression driver.

    Specifications:
    • 8 Ohm
    • 98db - 2.83v/1m
    • Up to 500 watts power handling
    • 35hz - 20khz in a ported 5cuft cabinet tuned to XXhz with three 3" ports
    • 65hz - 20khz in a ported 2.5cuft cabinet tuned to XXhz with four 2" ports
    • 75hz - 20khz in a sealed 2.5cuft cabinet

    Important Design Details: When used for movie watching you will always need to pair them with a subwoofer that can handle the lower bass frequencies. I would recommend at least two powerful 18" subwoofers to pair with the Vortex-15 speakers.

  4. Teasing us with that thread title lol...

    You big tease....

  5. For some reason, the build photos aren't loading :)
     
  6. Just in case I can't figure out how to insert another post up there.........
     
  7. My eyes are playing tricks on me! I see the Vortex kits available for purchase!
     
  8. Any chance a sealed Vortex 15 could be used atop the MBM-15LX, crossover at 200Hz?
     
  9. No problem using an active crossover between the Coax and the MBM at 200hz, could do this with most of the other kits as well. A passive crossover is not so easy.
     
  10. I was thinking of a Yung SD500 plate amp powering the MBM. There’s an active crossover on it with a 200Hz maximum LP. The baffle width on the coaxial would be such that the baffle step rolloff would start at 200Hz with large round overs (a pill-shaped enclosure).

    Does this sound correct?
     
  11. Care to share the t/s specs of the 12 and 15" coaxial woofers?
     
  12. It may work but you might have to play with the phase and polarity to get good integration between the MBM and speaker as the lowpass filter will add delay to the MBM which will throw off phase alignment with the Voltex-12.

  13. Great points, thank you.
    FWIW, my intention was to use the Vortex 15. I know you recommended a 18” sub to fill in the low end with the 15” coaxial but the MBM only comes in 12” & 15” flavors (as you already know).
     
  14. I was set on the HTM12 for LCR then these came in. My listening preference is more on the "detailed" side of things - meaning I like to hear the metallic clicks, zings, clangs of movies. It gives it that added realism. From what I've read, these have more low end but Ill be running my LCR with 2 15 subs. I'm more interested on which has more detailed highs. Thanks in advance.

    Erich / Matt - any thoughts on comparison?
