{"product_id":"vienna-acoustics-maestro-grand-reference","title":"Vienna Acoustics Maestro Grand Reference","description":"\u003cp\u003eMost center channels are afterthoughts. They use smaller drivers, cheaper crossovers, and get stuck on a shelf to fill a gap between the towers. The Vienna Acoustics Maestro Grand Reference is not that speaker. It uses the same flat X4P Composite Cone driver technology as Vienna's Reference floorstanders and a 1.1-inch hand-coated silk dome tweeter, runs a genuine 2.5-way crossover with Bessel filters, and reaches down to 28 Hz. Vienna built it to be a full-range speaker that happens to sit horizontally.\u003c\/p\u003e\n\n\u003ch5\u003eKey Features of the Vienna Acoustics Maestro Grand Reference\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eDual 6\" X4P Composite Cone mid-woofers\u003c\/b\u003e: Flat spidercone with glass fiber reinforcement and recessed fabric center-cone for rigid, piston-like diaphragm movement\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e1.1\" hand-coated silk dome tweeter\u003c\/b\u003e: Extends well down into the midrange\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e2.5-way crossover with Bessel filters\u003c\/b\u003e: 6 dB and 12 dB slopes using MKP capacitors (1% tolerance), air-core coils (0.7% tolerance), and inductance-free metal film resistors\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDual front-ported bass reflex\u003c\/b\u003e: Impulse-optimizing QB3 alignment with bass down to 28 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFull-range LCR capability\u003c\/b\u003e: Can serve as a left, center, right, or surround speaker, not limited to center channel duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e91 dB sensitivity into 4 ohms\u003c\/b\u003e: Vienna recommends 30 to 300 watts of amplification\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePiano finish\u003c\/b\u003e: True Piano Black or Piano White\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eVienna's X4P Composite Cone: The Driver That Defines the Reference Series\u003c\/h5\u003e\n\u003cp\u003eTwo 6-inch X4P Composite Cone mid-woofers sit at the heart of the Maestro Grand Reference. The cone is Vienna's new X4P mixture, reinforced with glass fibers. It is flat rather than conventional, a patented spidercone with rear bracings Vienna lists at 18 mm (bass) and 14 mm (mid). That stiff, light construction lets the diaphragm move as a single piston.\u003c\/p\u003e\n\n\u003cp\u003eEach driver also uses a recessed, double-coated fabric dome instead of a standard dust cap.\u003c\/p\u003e\n\n\u003cp style=\"text-align: center; margin: 20px 0;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/maestro-grand-reference_inline_driver_detail.jpg?v=1774864573\" alt=\"Vienna Acoustics Maestro Grand Reference X4P Composite Cone driver and silk dome tweeter detail\" style=\"display: block; margin-left: auto; margin-right: auto; max-width: 100%;\" loading=\"lazy\"\u003e\n\u003c\/p\u003e\n\n\u003ch5\u003eThe Maestro Grand Reference Tweeter\u003c\/h5\u003e\n\u003cp\u003eThe 1.1-inch hand-coated silk dome tweeter extends well down into the midrange, and Vienna lists the same 1.1-inch hand-coated silk dome for the Beethoven Concert Grand Reference. For a center channel, that midrange reach matters more than in most applications. Dialogue intelligibility depends on a clean, uncolored handoff from mid-woofer to tweeter, and the silk dome handles it without the metallic edge that aluminum or beryllium alternatives can introduce over long listening sessions.\u003c\/p\u003e\n\n\u003ch5\u003eA 2.5-Way Crossover in a Center Channel\u003c\/h5\u003e\n\u003cp\u003eMost center channels run a simple two-way crossover. The Maestro Grand Reference uses a 2.5-way crossover with 6 dB and 12 dB Bessel filters.\u003c\/p\u003e\n\n\u003cp\u003eThe crossover components are MKP capacitors at 1% tolerance, coils at 0.7% tolerance and inductance-free metal film resistors at 1% tolerance. Vienna uses soft Bessel slopes because they exhibit the least phase shifting.\u003c\/p\u003e\n\n\u003ch5\u003eFront Ports and Cabinet Construction\u003c\/h5\u003e\n\u003cp\u003eThe Maestro Grand Reference uses a dual front-ported bass reflex enclosure tuned to a QB3 (Quasi-Butterworth 3rd order) alignment. Front ports are a practical advantage for a speaker that typically sits on a shelf or credenza below a display. The QB3 tuning keeps bass tight and defined, favoring transient speed over maximum low-end volume.\u003c\/p\u003e\n\n\u003cp\u003eIt comes in true Piano Black or Piano White. At 24 inches wide, the Maestro Grand Reference accommodates its horizontal driver array without the compromises that narrower center channels make by stacking drivers vertically or angling them off-axis.\u003c\/p\u003e\n\n\u003cp style=\"text-align: center; margin: 20px 0;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/maestro-grand-reference_inline_rear_terminal.jpg?v=1774864574\" alt=\"Vienna Acoustics Maestro Grand Reference rear terminal panel with gold binding posts\" style=\"display: block; margin-left: auto; margin-right: auto; max-width: 100%;\" loading=\"lazy\"\u003e\n\u003c\/p\u003e\n\n\u003ch5\u003eBuilt to Match Vienna's Reference Floorstanders\u003c\/h5\u003e\n\u003cp\u003eVienna designed the Maestro Grand Reference as a no-compromise tonal match for three specific floorstanders: the \u003ca href=\"\/products\/vienna-acoustics-lizst-reference\"\u003eLiszt Reference\u003c\/a\u003e, the \u003ca href=\"\/products\/vienna-acoustics-beethoven-concert-grand-reference\"\u003eBeethoven Concert Grand Reference\u003c\/a\u003e, and the \u003ca href=\"\/products\/vienna-acoustics-beethoven-baby-grand-reference\"\u003eBeethoven Baby Grand Reference\u003c\/a\u003e.
