Bottom Line:   
I have had these speakers since they were born. I 'm a jazz bass player, I hear harmonics
too.They replaced the classic JBL-4312 and to my shock! They blew me a way! Since then
they have been driven by some of audio's finest hardware(Denon AVR X4000). They also
introduced the revolutionary "transducers" instead of drivers. They can be driven by a low 30
watts and a high of 325 watts(tested) but at 60watts they will perform to specs(tested). why
anyone would need 300watts to drive bass reflex speakers? These speakers went unnoticed
at a time when home theater was on the horizon and people were looking at smaller speakers
they were being sold at bargain prices(480.00 a pair). If you can find a pair(eBay e.t.c) run and
get them! When your friends with the high price stuff hear them they will be amazed!

Bottom Line:   
I now own 3 pairs of this line of speakers from JBL. Two S312ii and one S310ii. They are very efficient producers of clean sound. The highs can come across as a bit harsh to some people. They certainly play louder and brighter than anything i've compared them against. With a good amp, they will produce excellent bass. I use a subwoofer in 2/3 rooms but one could live without a sub with the S312ii and even the S310ii in smaller rooms.

The sound quality is quite good for this price range. Speakers costing thousands of dollars each will likely sound better, but for a few hundred bucks these really shine.

12" woofers are hard to find in newer speakers anymore. Having found all three pairs of these for under $200 used; i am quite happy. 3 rooms have good sound and it didn't break the bank.

Bottom Line:   
Critical listening from an untrained ear that probably can`t tell flat from sharp using a low power amp. hahaha
To drive these speaker properly you need a real amp with 300WPC RMS then they come alive.
As a Professional Jazz musician with a trained ear I hear harmonics 90% of you will never hear and my ear along will my fellow musicians, tells me these are some of the finest budget speaker you will find anywhere and will hold there own against speakers costing 5 times as much. That is why we Pro`s use JBL in the studio and on the road. My hats off to Greg Timbers and his staff.

Bottom Line:   
I bought these speakers couple of years ago but really never got myself to find a way to explore its potential, till couple of days ago when i had a friend give me his Carver - sunfire 300 power Amp.Well I was blown away with the performance of the speakers.
The 312 generally says max 250 at 8 ohms ,,,though the 300 watt rms amp chur ns out more than needed to have an astounding speaker system.
I have picked up the sunfire 300 at a good deal and wud def sugest the same for any one looking to harness the power of the JBLS312.
