Klang+Ton 06/2014
"Used  in the speaker building concept MonaLisa: usually rather unobtrusive  with a harmonised tuning, this speaker can still show an impressive  performance, even at very high volume levels and when listening over  longer periods of time. It provides a powerful bass and midrange  reproduction and features an elegance which can only be realised with  high-quality materials."
