Each buyer receives our simple, step-by-step, confidential, and proprietary setup instructions (not published).
Dream Maker LCS provides a unique listening perspective via new benchmarks in the following qualities audiophiles crave:
1. Soundstage density
2. Soundstage expanse in all three planes
3. Mode damping effect in the bass range
4. Distinct musically natural image outline
5. Horn image density with no “cupped hands” effect
6. 3-D imaging formerly the domain of planar loudspeakers
7. Maximum SPL and dynamic contrast mimicking the best horns
8. Specific and stable image location in all three planes of the stage
9. Consistent image quality throughout the stage including extreme corners
10. Images floating in space and detached-from-the-box formerly the domain of planar loudspeakers
11. “Atmosphere” around each image increasing ability to focus on separate musical lines without diminishing the whole
12. Minimum “etching” as sometimes occurs with inferior recordings (maximum levels of detail and spatial qualities without fatigue inducing effects)
13. Higher emotional connection with the music, listeners move from passive to active, decreasing the gap between listeners and the music’s author and performers
14. Increased ability for the ear/brain mechanism to relax into a restful, non-fatiguing state of illusion that live musical events occur in the sound room. This applies regardless of scale, from solo flute to the largest chorus and orchestra
15. Pitch accuracy throughout the range increases ability to follow counterpoint and the musical whole, also increases differences between instruments with closely related harmonic structures such as oboe and clarinet
16. Larger sweet spot in all three planes, musical involvement sitting or standing, accessible to untrained ears throughout the room and even outside the room. Stand with back against the front wall then slowly walk toward the room center. The effect mimics standing in the middle of the musicians then walking among them and eventually standing in front of them.

Prior Benchmark: Not Stereo
Our benchmark for spatial qualities is not the stereo format but rather Ray Kimber’s proprietary Iso-Mic DSD 4.0 reproduced with original hard drive, two 8’ tall Sound Lab stats per each of four corners (eight stats total), and oodles of Pass Labs class A mono blocks. This is the rare system whose performance matched its princely $330k MSRP. Unfortunately it will never again display because of wear and tear on the stat panels. We tip our hats to Ray for assembling a proprietary recording technique and playback system to shame the stereo format, at least till now.
When Duke setup the first generation Dream Maker for TAS Editor/UCLA Math Professor Dr. Robert E. Green, Robert said to Duke, “Loudspeaker designers ask the wrong questions.” Dream Maker LCS asks the question: Can we move the loudspeaker performance benchmark with pre-existing technology custom-tailored to a novel radiation pattern? Duke generously shared his speaker philosophy and Dr. Floyd Toole’s theories with James, which led to LCS. Duke also “gilded the LCS lily” with specific confidential performance enhancements.

Pre-Existing Technology in a Novel Package
We regularly and thoroughly audition the most costly and exotic loudspeaker technology. From exclusive boutique crossover components to thousand dollar drivers to solid aluminum enclosures to active digital to planar to hybrid to resin-molded Fibonacci shapes, to products in between and beyond. We are only pleased to hear and see the results of designers constantly searching for new outer limits without regard to cost.
Our goal with Dream Maker LCS was to move the benchmark employing affordable pre-existing technology in a novel package.
Easy Setup and Synergy
Our prior audio experience is that the higher one climbs the performance ladder the more costly and laborious is each successive step. Mistakes in room design and component selection also become more costly.
Dream Maker LCS allows more fun, less drama, and lower cost in assembling a system of the highest caliber. Component selection is more about “flavor” and less about abject failure vs. sublime success. Dream Maker LCS offers premium performance with the widest flexibility in room setup and component selection.
Maximum LCS Potential
James experimented with Duke’s radiation pattern titled “Vertical Offset Bipolar” (http://audiokinesis.com/product_ak_dream-maker.html). Later James experimented with Dr. Floyd Toole’s side-firing ambiance theories, which led to Late Ceiling Splash (LCS).
LCS improves on the already superb ambiance qualities associated with Duke’s 2008 TAS Golden Ear Award-Winning Dream Maker (original). The original Dream Maker employed Duke’s “Vertical Offset Bipolar” radiation pattern. LCS employs ceiling-reflected output from an “Effects Speaker.” Prior loudspeakers employ the front wall for reflection and ambiance effects. The ceiling’s closer proximity to listeners increases effects quality and intensity. Bipole, dipole, and omni-pole speakers require great distance between the speaker and front wall for maximum performance. Conversely, LCS excels even when speakers site flush with the front wall (though greater spacing might increase stage depth).
The Main Speaker (MS) employs one 10” mid bass (11? flange) and one compression tweeter loaded in a 13” x 6.5” horizontal waveguide. The Effects Speaker (ES) employs special undisclosed architecture. Duke tailored the MS and ES to maximize overall system performance.
Ambiance Theories Uniquely Applied
For ideal ambiance effects, a leading loudspeaker engineer specified ideal delay window or “10ms to 20ms” for reverberant field. LCS ambiance delay achieves the 10ms target even in a ceiling only 7.6’ (91”) tall and even with the Effects Speaker sited flush with the front wall.
Listeners first hear direct output from the MS which is low in distortion, high in resolution, and high in linearity, pitch accuracy, and pitch stability. There is minimal MS radiation from floor, ceiling, and adjacent sidewall. Primary center fill increases with MS toe-in axis about 12” IFO a centered listener at the sweet spot.
10ms after MS direct line-of-sight output, listeners hear high-intensity ES output reflected off the ceiling. The ear/brain mechanism would perceive earlier arriving energy as distortion. The ceiling increases the height of images and the height of music energy in the room. There is no other method to reproduce the resulting effect. ES output creates a deep sense of pleasurable immersion ala MBL onmi-pole. MBL omni-pole imaging is extremely dense, but outlines are less clear and image size is bloated. LCS approaches MBL image density, but with natural size and outline.
The ceiling source also increases image layering in all three planes. If there is better image layering we’ve not heard it, at least not in stereo.
All the above benefits accrue without proximity effects even standing near the Effects Speaker. Why? The ES has minimum proximity effect because of its radiation pattern, the intensity of the ceiling reflection, the listener’s proximity to the ceiling, and the listener’s proximity to the Main Speaker.
The following is a unique and interesting side effect: place your head against the front wall facing toward the room center. Slowly walk toward the sweet spot. The effect is akin to standing among the musicians then walking slowly in front of them. Dream Maker LCS is the only speaker with this effect. It’s beyond a fun artifact. Walk anywhere throughout the room and notice how closely performance mimics the sweet spot. Stop at the room’s threshold when you enter and compare performance to your best prior reference. We are pleased to offer this unique audio performance quality available nowhere else.
There is no “head-in-a-vise” sweet spot, the curse of planar technology. Rather we offer a new benchmark in sweet spot size, with superb performance standing or sitting. Walk around the room while music plays to test this claim. This system provides the largest area for superb musical enjoyment standing or sitting, while still offering superlative imaging.
Our personal favorite Dream Maker LCS qualities are pitch accuracy, pitch solidity, increased enjoyment of the most complex musical counterpoints, and layering of positive and negative images in a stage of epic proportion.
Besides the aforementioned superlatives Dream Maker LCS is the proverbial “party animal.” Upon testing the original Dream Maker at RMAF Lynn Olson said it played louder and cleaner than any other speaker at that show. Dream Maker LCS draws even novices in because it better mimics real live music. And it requires only moderate power.
Duke conservatively specifies each Dream Maker LCS channel (MS + ES) for mid-90 dB anechoic SPL @ 2.83V @ 1M (16 Ohm wired in series, 4 Ohm wired parallel). 90W yields approximately 113 dB with 1 dB thermal compression (1/10th maximum RMS input) per channel anechoic.
Duke and James invented the architectural philosophy described herein. Dream Maker LCS is the first and only speaker to offer it. Dream Maker LCS is not small and it’s not low in cost, though it outperforms much larger cost no object systems.
The proof, as they say, is in the pudding. The world’s first permanent Dream Maker LCS display is seventy-five minute drive NE of Salt Lake City, Utah. If you like geographic splendor and outdoor activities you could do worse than visit Cache Valley. James would love to show you his favorite mountain bike trail (The Bonneville Shoreline Trail) and Bear Lake fifty minute drive E is gorgeous. Park City is a ninety-minute drive SE. Powder Mountain one-hour SW has some of the world’s most delectable skiing. Blue Bird restaurant offers fresh trout lunch from Logan River for less than $5.00. Cache Valley’s best hotel is one block north.
Compare Dream Maker LCS vs. any system regardless of cost, size, complexity, or technological merit: active or passive, modular or single enclosure, open baffle or not, digital controlled or not, horn, planar, or direct radiator.
Duke tailored this new loudspeaker system to exploit James’ LCS array. We humbly invite you to audition this new two-box loudspeaker system, and hope you find its unique charms irresistible.
Home Theater, Dual Use HT/Music
Our system is dual use HT/music. We employ a Vutec 92” retractable perforated screen, dead-silent ceiling-mounted Mitsubishi 1080P projector, and good light control (basement, one small window with Venetian blind over black out shade).
You can assemble one affordable dual use system in one room with better performance than other dedicated single use systems, even if your viewing distance is short and you need only a small to medium size screen (custom small screen available in almost any size).
