High Back EMF, Trifilar Woofer
High Back EMF, Trifilar Woofer

Sunfire's unique "Trifilar" voice coil is actually 3 dual voice coils rolled into one. These innovative designs are more efficient and able to deliver up to an 80% increase in output. This means that the woofer can play very loud, much louder than typical designs. At the same time, our Trifilar drivers are also significantly lighter than standard multi-layer voice coil designs. This means that the driver responds very quickly - making drum kicks, and other percussive effects tighter and more lifelike. On the same note, having a lightweight woofer means that it has improved top-end response. This makes for smoother integration with the tweeter in the critical upper midrange, lower treble range - where much of the vocal information lives. Therefore spoken word sounds very natural - not muffled or tinny.

High Resolution Series Bi-Pole Surround - HRS-SAT4BIP

The HRS-SAT4BIP is the perfect timbre match to the HRS-SAT4 satellite speakers. A purpose-built, on-wall surround speaker, the HRS-SAT4 BIP features dual ring-radiating, silk dome tweeters that are acoustically optimized to provide an enormous soundstage. These tweeters are similar to those found in high-end European speakers costing many times more.

The low-profile cabinet’s curved sides are not only aesthetically rich, but make for a smoother wavelaunch and improved imaging compared traditional “box” speakers. A single 4.5" Kevlar woofer provides the dynamics need for today’s high-resolution sources, and features a one-of-a-kind "Trifilar" voice coil. This ultra lightweight, three-layer design delivers up to an 80% increase in output then compared to conventionally wound designs.
