So I bought a pair of L112s a while ago from a garage sale, not expecting much. Repaired the surrounds and fired them up and was blown away by the "reality" of the speakers.
I had recently just finished restoring a pair of Infinity RS-6000s which were my current favorites.
After considerable A/B (limited space), I chose the JBLs and sold my 6000s.
Well after six months, I have become a bit disenchanted with them. I have read here that the bass on the L112s is powerful and I have a nice Denon receiver that pumps out a decent 140W x 2 RMS, clean with good reserves.
The mids and uppers are what locked the JBLs for me against the Infinity. But the bass was not comparable. The dual acoustically suspended 10" drivers and the 2.5 ohm impedance (which drove the Denon to 350W x 2) if the Infinitys was in a different league. The Infinity bass was deep, fast, and tight. Always there, hitting you in the gut then disappearing. Going low (37 Hz) effortlessly.
The L112s is the opposite, "there" but not always powerful. Loose and sometimes muddy.
I have checked polarity and the drivers seem to be in fine shape.
One note, when I first rebuilt the speakers, one of the woofers had been replaced and the internal woofer wires were rolled. So I swapped them back and checked overall polarity with a battery. The speaker pair matched.
So, after my diatribe, I am curious to get everyone's opinion on these L112s as far as bass.
I have not been able to get the bass anywhere near what I would like and am beginning to despair. An amazing speaker, tainted with a poor low end?
Maybe I need a full 300W?
