Energy had speakers in Best Buy, but they also made higher end speakers as well. You’ll find great used options out there if you find the Veritas line, their highest... or Reference Connoisseur (RC) series, their mid-level which was a super high quality/price ratio.
They are definitely smooth and not bright or brittle, compared to speakers widely known to be on the brighter side, but there’s nothing missing and they are very very good with imaging, tone and timbre.
Look for Veritas 6.2, or 2.3i, towers. And/or Reference Connoisseur ...RC-70 towers. Can’t go wrong, and will get a screaming deal (value) on some super speakers.
