Description
For sale: pair of ESS AMT-1 (Heil Air Motion Transformer) tweeters, tested and fully working, no cosmetic issues.
Built for DIY
These AMTs are a solid choice for:
DIY speaker projects
upgrades (replacing a conventional dome/driver with an AMT)
experiments with proper crossover design (passive or active/DSP)
You don’t buy an AMT for branding: you buy it for the speed, resolution and “air” typical of the Heil AMT principle.
Condition Working condition: tested, OK
Cosmetics: no defects
Original packaging: not available (see shipping)
DIY note
Please check mechanical fit and project integration (crossover slope, crossover point, etc.).
If you tell me what you’re building, I can provide extra measurements / close-up photos to confirm fit before you buy.
Shipping available with very protective double-box packaging, since AMTs deserve careful handling.
Private sale: no returns/warranty, item exactly as described and shown.
