At $275 a pair these relatively inexpensive Dayton PS220-8 8" full-range drivers ---{once they've had their cones treated with a somewhat expensive cone treatment}--- are absolutely phenomenal sounding! So good in fact, I removed the $2K Fostex FE208ES-R drivers that were previously installed and replaced them with the PS220-8 drivers. I even know of a man who replaced the AER drivers that were in his Lamhorn 1.8 with the treated Dayton PS220-8 drivers!
