I just finished this pair of Energy ESM-2 speakers today.
These speakers were a step own from Audio Products International flagship speakers the Energy 22's. They look very similar to the Energy 22's but no where near the same build quality or sound stage.
These speakers are well braced on the inside and I added a bit more dampening materiel when I put them back together.
Of course the crossover got a new polyester cap at the same value but with closer tolerance and the woofers got new surrounds. I am breaking in the speakers as I wright this post and I absolutely loving these speakers.
I had a pair of Energy ESM-3 speakers in the past and I am no fan of the Vifa D19 tweeter and found that pair fatiguing, this pair of ESM-2 speakers is outfitted with a pair of Vifa D 25 TG which are much smoother.
The ESM-2 is a nicely balanced musical loudspeaker, the sound stage is three dimensional with great imaging. This pair of speakers is worth restoring to original or better spec if you come across a pair in need of rehab.
