While Gemme is out of business, most of their drivers we're " off the shelf " units. I was able to source a spare tweeter and woofer from Madisound for less than $80. not that Ineeded them, I just wanted backups ( just in case), because the Tantos are that good.
If you're still serious about the Tonics, see if you can source the drivers easily enough from another source. Then all you'd really need to be concerned with are crossovers, and it's somewhat rare for them to go out on speakers this young.
