Summary: For the price I paid, there is little I can complain about. These speaker need better than average components to realize their full potential. After over 40 hrs of listening using first, my Denon AV-3802 receiver, then using Emotiva XPA-3 Amplifier, with the Denon receiver as Pre Amp on two chanel only, I can make the following staments that applies to my particular listening setting: At first the highs are a little bright, but as the speakers get pass about 15 to 20...
Summary: Very well ballanced sounding, superb design, really capable to reach incredible sound pressure levels without any noticeable trace of effort.
Pros: no joke building materials, no joke building concept; pleasant either to listen to or just to look at them in my listening room - there's nothing to annoy me; all complaints are minor and don't worth mentioning.
Cons: loose manufacturing quality control - the holes for attaching the front grill are drilled 5 mm lower than necessary at the one speaker, the other one is OK, so inspect every piece of JBL speakers at your hifi shop before laying down the cash; L890 need really high power feeding to disclose their full bass potential.
Excerpt: Es un altavoz de suelo dual, con una cúpula fabricado en aluminio, un Mylar® de 3/4 pulgadas. Los JBL L890 pesan casi 30kg cada uno!, una burrada, pero son unos pepinos en el sonido, miden cerca de un metro de largo, son un poco gruesos para mi gusto, y por supuesto son para habitaciones grandes y con sitio.
Pros: El sonido sobre todo la alta frecuencia, gran capacidad de volver locos a los vecinos
