Podjetje Opera predstavilo končne različice nove serije zvočnikov Callas

02.08.2014 - Napisal: trancedeejay

Te dni je Opera predstavila končne verzije nove serije zvočnikov Callas in sicer monitor Callas in samostoječi Grand Callas.

Modela sta popolnoma prenovljena. Obema je skupna zelo kompaktna in masivna izdelava pri maksimalnih zmogljivostih. Tako Grand Callas praktično zamenjuje legendarnega Tebaldija, zavzame pa manj prostora, je cenovno ugoden ter s tem na trgu zelo konkurenčen.

Monitor Callas je od prejšnjega modela obdržal kompaktno obliko, na pogled ne deluje večji, je pa krepko zmogljivejši z »močnejšimi« pogonskimi enotami. Kljub temu, da Callas 2014 ni podedoval visokotoncev na hrbtni strani, ima večji, močnejši in bolj naraven zvočni oder .

Kar se tiče moči, zvočnika nista zahtevna, saj je dovolj že 10 kvalitetnih »w« pa tudi impedanca ne niha veliko, med 3 in 4 ohme.

Lastniki majhnih sobic bodo veseli, da je Callas primeren za poslušanje že na malo več kot »m« od zvočnika .

Callas Grand pa bo v velikem prostoru s svojo nevsiljivo obliko estetsko in zvočno zapolnil prostor.

Končni izgled in izdelava so tradicionalno na visokem nivoju, v »mahagonij« ali »oreh« finišu .
