Totem uses dynaudio and seas drivers and not cheap chinese drivers as Ttowntony stated...
Totems attention to detail does not end with the cabinetry. The Model 1 Signatures use Totem-modified 5" Dynaudio woofers and 1" SEAS aluminum tweeters. The Dynaudio woofer has a 3" voice coil, and being a sadist, I drove it very hard to see how much abuse it could handle. The Model 1 Signature differs from the Model 1 in that the woofer and tweeter are connected to the crossover with shielded silver Teflon dielectric, and multi-strand oxygen-free copper wiring. The crossover uses larger and higher-grade oil-dielectric capacitors, and metalized polypropylene capacitors. Totem feels that grilles muck up the sound of the Model 1 Signatures, so they are not supplied (although you can buy them for $40 if you need them). I mention this as a warning to people with small children and pesky felines (Im a dog lover). The tweeter is covered with a metal mesh cap, so I think that you are OK on that front. The Dynaudio woofer seems to be very strong, and I think that it would take something like a solid right from George Foreman or a thrust with a metal object from someone like O - (Ill restrain myself at this point) to damage the woofer. The Model 1 Signatures frequency response is rated from 50Hz to 20kHz +/- 3dB, with a sensitivity rating of 87dB/W/m. They are also a 4-ohm load and in my experience, not the easiest speaker to drive.
