RHAPSODY* in 4D SPEAKER SYSTEM

…For those of you who have read my reviews over the past 30 years, you know I am not given to hype and I am very hard to impress. However, the sound of the Rhapsody Speakers did impress me. This is one of my closest encounters to experiencing sound so close to the live performance via speakers. The dynamic range, the air around the voices and instruments, the way the leading edges were rendered and the tuneful way that the bass was reproduced really did sound very close to the real thing. And here is the kicker, the Rhapsody retails for $25000. I have no hesitation in proclaiming that these speakers were better in most respects than many of the speakers I have reviewed and heard that carry a 6-figure price tag.  Even if you have a 6-figure budget, I would strongly recommend that you listen to the Rhapsody Speakers before you pull the trigger. You could end up with speakers that satisfy you in every respect and still have enough money left over to splurge on a fully loaded BMW 3 series.

Blueberry Hill Audio’s more affordable Nocturne Speakers are priced at $15,000 and although I did not hear them, Marlen claims that they have the same tonal characteristics as the Rhapsody Speakers. If that is true, it would make them an incredible bargain as well.

 

RHAPSODY in 4D is a MODULAR, FULL RANGE, BIPOLAR and ADJUSTABLE Speaker System with self powered, direct servo Sub Woofer.

                                                                   
RHAPSODY in 4D Speaker System employs two 8" FULL RANGE drivers and one super tweeter in each channel. All drivers are internally wired to dedicated speaker terminals for direct coupling with amplifier(s) without crossovers. Parallel
connected FULL RANGE drivers raise system sensitivity to 100 db.
All internal wiring uses proprietary, hand made cables, utilizing purest (.999) silver conductors and unbleached cotton dielectric.   
One of two in-face connected, full range drivers in each speaker positioned in the front of a dedicated sealed enclosure. The second driver is positioned in the back. Back to back placement of identical drivers connected in-face eliminates vibration in a sealed, horizontally placed full range enclosure.      

RHAPSODY in 4D Speaker System employs a SELF POWERED, direct servo SUB WOOFER module. This module consist of two direct servo 12" drivers. Each driver is horizontally positioned in a sealed dedicated enclosure 4" apart and facing each other. Both sub woofer enclosures are joined and are half closed in the back by the amplifier cabinet. The connected in-face sub woofer drivers, placed face to face, eliminates vibration in each of the two sealed, vertically positioned sub woofer enclosures. Combined movements of all RHAPSODY in 4D drivers makes the speakers vibration free.

Sub woofer module of RHAPSODY in 4D Stereo System is powered by an 800 watt direct servo amplifier - 400 watt per each driver. Drivers are connected in-face and when active, create a "piston" like motion towards each other, forcing the sub woofer to perform significantly faster.
Direct servo amplifier performance can be fully adjusted via multiple fine tuning control knobs. RHAPSODY sub woofer is an essential part of RHAPSODY in 4D Stereo System but as independent module, can be used with any existing stereo system.
One of the most important specifications of an audio driver is angle of horizontal dispersion. Midrange drivers have an angle of horizontal dispersion significantly larger than tweeters. In all existing Hi-End Stereo Systems midrange and tweeter drivers position is locked. Toeing-in speakers in the search for the best tweeter performance - imaging, sound stage, depth, etc. can degrade the performance of midrange driver(s) and visa versa. Therefore, midrange and tweeter drivers must have the option of being independently adjustable.
After placement in the listening area, the RHAPSODY in 4D Stereo System, can and should be "tuned" to optimal listener(s) requirements by adjusting and locking the horizontal position of midrange and super tweeter enclosures. Time alignment can also be optimized by adjusting and locking position of the super tweeter driver, inside the enclosure.
