Replacing timpani heads is not as simple as replacing a snare, tom, or bass head. Please read through our
Replacing Timpani Heads Guide if you're not 100% sure what size you need.
Remo RC-Series (Renaissance) Hazy Timpani Heads project through orchestras and wind ensembles with a warm, dark sound that blends particularly well. They're as close as you can get to real calfskin in terms of sound quality and consistency, and require only a fraction of the maintenance.
The steel insert ring provides a strong, very thin bearing edge for the head to rest upon, increasing tuning consistency and making the seating process easier to deal with. This ring is most effective at boosting sound quality, but the head will be significantly raised above the counterhoop.
Do not use steel insert rings if you plan on taking the timpani outside - the ring will rust when exposed to moisture.
