| Thiel Owners GS - you might call Rob Gillum at Coherent Source Service about this matter. Tinsel leads do eventually fatigue, and Rob has replacement moving systems on hand. The little I know about ferrofluid is that there are many types and quantity is critic... | |
| Thiel Owners You can use the battery to gauge woofer movement. Are both channels moving similarly with the 6 volt signal? | |
| Thiel Owners Put your preamp in mono if you can. Even if you can't, both woofers should be moving about the same amount. | |
| Thiel Owners JA - recovery was immediate, since re-entry does not say no. I wish I had more time with Rob, but our schedules only overlapped by a couple of hours. We're on firm ground with mutual goals. The trip also included other contacts and prospects. Gett... | |
| Thiel Owners Nice room dimensions.Don't switch anything until you know if there is a polarity problem.Disconnect the cables at the power amp. Connect 6V battery - minus to black wire and touch + plus to red wire. The coax and woofer should both move out. Repea... | |
| Thiel Owners that's amp end of the disconnected RED wire. | |
| Thiel Owners Lemming - what's your ceiling height?Are all drivers working? Finger on the cone test.You can check driver polarity with a 6 volt lantern battery. Best test is battery plus to wire at the disconnected cable at the power amp. All drivers should mov... | |
| Thiel Owners Yes, indeed - there are personalities who go crazy knowing that each and every day their tubes are getting noisier and noisier . . . and when is proper time to replace them and on and on. Makes solid state easier to love. | |
| Thiel Owners Brett - what you say has merit. Deciphering phase / polarity behavior has a lot to do with the ear-brain's reference, and having the deep bass delayed does affect the overall sonic fingerprint. But keep in mind that the vast majority of speakers i... | |
| Thiel Owners Dsper - not to worry, eventually we'll make them sing. | |
| Thiel Owners JA - if and as a small company might be created to keep Classic Thiel speakers updated, all models are in the mix. What emerges as upgrade solutions will apply to all models because the design goals and methodologies of all models share their DNA ... | |
| Thiel Owners sdecker - let's not conclude that the baffle pocket is a sonic problem. In fact, the 20 gauge steel grille plate with its fabric fills that pocket to be flush with the edge curves. The inner edges are not parallel or concentric with the driver, an... | |
| Thiel Owners Oops, that reply should have been to sdecker. | |
| Thiel Owners Andy - my experiments show that a felt edge at the driver surround is not good. It causes its own reflection / diffraction effect. Good results have come from beveling the felt edge and by covering everything up to the surround with Ultrasuede for... | |
| Thiel Owners Beetle - FWIW, my experiments have led to a 2-layer system as having sonic synergy. Not ready for prime-time, but anyone is welcome to play.1/8" F11 (or F15N) felt plus top layer of Ultrasuede LT (lightest grade 0.6mm thick). And the clencher is c... |
