Difference between Energy 22, and Reference 22?

1. Thicker cabinet walls strengthened with ten 1’’ thick braces.
2. Internal angles which are different from one another to eliminate standing waves inside the cabinet.
3. Special port arrangement in the speaker stand for further extended bass response.
4. All parts are matched to tolerances between left and right speakers, ensuring outstanding soundstage re-creation.

Thanks Brf.
