   of ports (none to four) to damp mid bass modes

   
   

9. Dimensions
   H x W x D: 26 x 18 x 10 inches, 45 degree angle on all 4 vertical
   corners (1.75” wide on front, 3.5” wide on rear)

   
   

10. Mid-Bass
    driver: 8 inch Faital pro sound from Italy, octagonal alloy frame,
    treated paper cone, accordion surround, neodymium magnet

    
    

11. Maximum
    power handling @ SPL @ 1M with 1 dB dynamic compression: 100Wrms @
    114.5 dB, active high-pass crossover 4th order @ 70 Hz (not
    included) allows 400Wrms @ 120.5 dB
    

    
    

12. System
    Design: constant directivity waveguide, smooth and consistent
    radiation pattern from mid range through treble, four rear-firing
    dual-flared ports behind mid bass drivers enhance reverberant field
    energy

    
    

13. Input
    impedance: 16 Ohm nominal, 12 Ohm minimum. Benign phase angle and
    flat impedance above the bass range.  AudioKinesis' renown low current load for OTL
    and any tube amp. High impedance improves SS amp distortion spectra,
    with greater even order/less odd order harmonics.
    

    
    

14. Treble
    Tilt: four steps via rear panel upper binding posts, (1) minimum =
    posts open/nothing attached, (2) included Mills non-inductive power
    resistor (higher Ohm value), (3) included Mills non-inductive power
    resistor (lower Ohm value), (4) maximum = posts shorted with
    included jumper wire

    
    

The higher the load impedance the greater is OTL amplifier power.  Atma-Sphere S-30 OTL power amp makes about 45W > Sigma 16 Ohm load, for 105 dB peaks.

AudioKinesis
Space Generator Reverberant Field Speakers, $3495/pr SRP:

AudioKinesis
designed Space Generator speakers (SG application developed by AK and
James Romeyn). Earlier SG application was called LCS for Late Ceiling
Splash. Earlier Dream Maker LCS speakers won 2014 RMAF Best of Sound Award and made TAS list for 2015 THE Show Best New
Speakers Under $15k/pr (Zephrin 46; AK Swarm Distributed Sub Array
also won 2015 TAS Product Of The Year Award).  AK Bienville Suites included in 2015 TAS "Best New Technology Under $20k" at AXPONA.    

SG
is a special auxiliary almost full range loudspeaker, adding ideal
reverberant field performance to Sigma or other primary speaker. SG
floor-mounts behind main/primary speaker. A continuous volume
control under the SG base matches SG level to primary speaker
sensitivity ranging from low 80 dB to low 90 dB.

SG
improves all performance aspects including density, spatial
qualities, even pitch sensitivity.

1. 
   Frequency Response:
   approximately 55 -17k Hz in-room

   
   

2. System
   Type: sealed enclosure, controlled directivity, flat spectral curve
   w/floor boundary reinforcement

   
   

3. Driver:
   US made Eminence 10” coincident w/polymer compression driver, 10"
   diaphragm acts as pattern control wave guide

   
   

4. Input
   Impedance: varies by level control setting, maximum volume 9.3 Ohm
   DC, minimum volume 25.3 Ohm DC

   
   

5. Dimensions
   W x D: 12” x 12”, base panel and cabinet angled 22.5 degrees to
   uncorrelate reverberant field (see images), grille height
   20.5”/16.5” maximum/minimum.
   

   
   

6. Treble
   Tilt: four steps via under side binding posts, (1) minimum = posts
   open/nothing attached, (2) included Mills non-inductive power
   resistor higher Ohm value, (3) included Mills non-inductive power
   resistor lower Ohm value, (4) maximum = posts shorted with included
   jumper wire

   
   

7. Amplifier
   Requirements: easy phase angles, flat impedance above the bass
   range, see “Input Impedance.”  All or most amps can safely
   drive SG parallel wired with most primary speakers (ask seller if in
   doubt). If primary speaker has sensitivity outside the recommended
   range, set SG level to maximum. Drive SG with a separate outboard
   amp with level control, recommend 50W+.
   

   
   

8. Sensitivity:
   A continuous volume control under SG base matches SG output to
   primary speaker sensitivity ranging from low 80 dB to low 90 dB. 
   To set SG level: use pink noise program w/SPL meter @ sweet spot,
   ear level, pointing @ 12 o'clock. Set main system volume for 65 to
   70 dB range from one primary speaker alone. Disconnect primary
   speaker; leave main system volume as-is. Adjust volume under
   associated SG for -13 dB v. primary speaker. Repeat for other
   channel.
