Perzina verticals have several interesting features rarely found in other pianos, including a "floating" soundboard that is unattached to the back at certain points for freer vibration, and a reverse, or concave soundboard crown. (There may be something to this; the Perzina verticals sound very good, their bass being particularly notable.) Soundboards are of solid Austrian white spruce. A premium series of verticals (model numbers ending in R) come with Renner AA or Abel Deluxe hammers.
A new line of Perzina grand pianos was introduced in 2011, designed and manufactured by Perzina in cooperation with a major European manufacturer. All contain solid Austrian white spruce soundboards, duplex scaling, and Renner AA or Abel hammers, among other high-quality components. A Perzina action is standard, with Detoa and Renner actions optionally available at additional cost. All models come with a slow-close fallboard, and most come with an adjustable artist bench.
The company's European headquarters says it ships many European materials to Yantai, including Degen copper-wound strings, Röslau strings, Delignit pinblocks, Renner hammers, English felts, European veneers, and Austrian white spruce soundboards. New machinery is from Germany, Japan, and Italy. According to the company, all the piano designs are the original German scales. The Renner actions used by Perzina are ordered complete from Germany, not assembled from parts.

Pianos made by: Petrof, spol. s.r.o., Hradec Králové, Czech Republic
The Petrof piano factory was founded in 1864 by Antonin Petrof in Hradec Králové, an industrial town 100 kilometers east of Prague, in the present Czech Republic. Five generations of the Petrof family owned and managed the business, during which time the company kept pace with technical developments and earned prizes for its pianos at international exhibitions. The Czechs have long been known for their vibrant musical-instrument industry, which also includes makers of brass, woodwind, and stringed instruments.
In 1947, when all businesses in the Czech Republic were nationalized by the state, the Petrof family was forced out of the business. In 1965 Petrof, along with other piano manufacturers, was forced to join Musicexport, the state-controlled import-export company for musical instruments. Since the fall of the Soviet Union and the liberation of Eastern Europe, the various factories that were part of Musicexport have been spun off as private businesses, including Petrof, which is once again owned and controlled by the Petrof family. Currently Petrof manufactures 5,000 vertical pianos and 900 grands annually.
Petrof recently introduced a series of six new grand piano models, named (in size order) Bora, Breeze, Storm, Pasat, Monsoon, and Mistral, from 5' 2" to 9' 2" in length. Most component parts are produced by Petrof or other Czech factories, including the hardware, plates, and cabinetry. Soundboards are of solid Bohemian spruce, grand rims are of laminated beech and birch, pinblocks are of compressed beech, plates are cast in wet sand, and hammers are from Renner or Abel. These pianos also boast several interesting features: The soundboard is custom-tapered and asymmetrically crowned for optimal resonance; the treble bridge is capped with genuine ebony for better transmission of treble tone; front and rear duplexes are tuned for tonal color; pianos are single-strung for tuning stability; an adjustable bolt has been added from the plate to the wooden cross block for additional tuning stability; and a decorative veneer has been added to the inner rim. The earlier series of Petrof grands with model numbers containing roman numerals will coexist with the new models as long as supplies last.
