I have had a pair of the JBL LSR 2328P 8" powered studio monitors for about 8 months now. They are fully broken in, as they are used several hours, almost everyday.
For the money, I am not sure that you could do too much better, but sound, as in most things in life, is preference based, and thus subjective. I personally like the 8" size woofers, and feel that having the larger woofer gives a more "full range" sound if you will. I do use these monitors in conjunction with the LSR2300 series subwoofer (the LSR2310SP), and the JBL MSC1, monitor system controller. [Reviews of these other 2 products are forthcoming soon]. I have the monitors mounted on the wall with ball mounts.
I use my monitors for mixing and general music playback as well. I like that the sound is honest enough that they are good for mixing, and good for music playback too. However, with one caveat (which is a good one) - if there are flaws with a recording, these will highlight those flaws, especially on the high end. This is great for my own recordings, but not always so great for general music playback, as lower quality sources really sound flawed. But, since the latter is not the primary function of these monitors, so be it.
They have the powered amplifier on the back of the speaker, with a treble attenuation switch, for the tweeter I believe, and also a volume control on the back - which I find very handy in setting the volume quickly for my listening position.
These JBL's have the fairly typical JBL low end clarity, and are also very clear on the high end. Sometimes the mids get a little lost and seem to recede a bit, but that could be me. The sound is uncolored and natural.
If one of these was damaged, I would most definitely replace it with another of the same unit... I would def. but these again, and think that, in their price range, they are a great powered studio monitor, and speaker in general.
