The following are being put up for auction (~closing shortly after lunch Saturday at the show) with all proceeds going to MAC. I understand MAC has a PayPal account, thinking good old cash works as well. If you see something and can’t make it, plz connect with someone that will be attending- thanks.
Please send me a direct message with bids (and any suggestions on how to better manage this, i.e. is it better for me to just track and not list the bidder?). I’ll periodically update this list.

Per 4thtry suggestion: Yes, the drivers have been used in my builds, and overall I’d say the drivers are _all in very good condition_ (if you bid and for any reason have an issue- _no problem_). Going back through my posts I’ve tried to ID builds/ dates. I will say the Heils, Beymas, MarkAudios, Epiques, and the Celstions _are in excellent condition_ / barely used / listened to for a bit (months?) in my living room. I’d be happy to additionally post a picture of any, just let me know. I included the Minimus 7s biz I know some have successfully updated Xovers for these little metal case speakers.

Suggestion: Adding a column to your listing indicating the current driver age and/or cosmetic condition would be helpful. (i.e., New, Unused, Used-Years, Good, Fair, Tested, etc.,)

Definitely (IMO) some very interesting drivers and leads to fun project builds. I realized I was just keeping many of them ‘cuz I really like the drivers - but better off in new hands than sitting on shelves.

I recently started an inventory of all the drivers and such I have and it exceeds 100! This does not count a few kits remaining from Meniscus that go together with some assembled crossovers. Probably should think about bringing some to Iowa as well, though I imagine the kits would be a hard sell.

“I recently started an inventory of all the drivers and such I have and it exceeds 100!”
Amateur… 😆
I know I’m above there as well, but I’ve been using a lot of them.

I won’t be at Iowa. Anyone attending that will likely also be at InDIY?

Sales pitch: Celestion FTX0617
This is their cast aluminum, horn loaded, common magnet 6.5 inch driver. [FTX0617 - Celestion](https://celestion.com/product/ftx0617/)
Celestion’s suggested crossover [https://celestion.com/wp-content/uploads/2019/09/FTX0617-Crossover-design-v2.pdf](https://celestion.com/wp-content/uploads/2019/09/FTX0617-Crossover-design-v2.pdf) which I just used as a starting point.
Again, all of these drivers are being offered No Reserve at IOWAdiy

Do it Craig ! Nice drivers , had a pair but traded them and some $$ for a pair of Vifa XT drivers. Always wondered how they would behave as a dedicated mid.

I only do Paypal. I usually do the “friends and family” option so I cover the fee for the transaction. I hope that works.
