Evans Strata Timpani Heads
Clean pitches
Evans synthetic timpani heads produce clean pitches that travel past the first few rows of the concert hall. These heads are crafted so that they will respond immediately and sustain consistently from pp to ff, with soft mallets or hard. No collar deviation
The age-old problem of collar deviation - that is, lifting to one side that results in disproportionate tuning has been eliminated.Pre-tensioned
Evans timpani heads are evenly pre-tensioned for exemplary performance every time.Strata
The Evans Strata orchestral timpani heads have a calf colored finish, moderate attack, very warm tone, an open sustain, a soft feel and have moderate durability. How do I determine the correct size Evans Timpani head to order?

ORDERING SPECIFICATIONS (To be used as a tool with the Timpani Head Reference Chart) Timpani heads are probably among the most confusing products to properly size. There are several drum manufacturers, each with different ideas on how the drums and heads should be sized. A Yamaha 26" timpani takes a different head size than a Clevelander 26" timpani. The Evans Timpani Head Reference Chart is up-to-date and should always be used when ordering heads.

The following is an additional guide to help you when ordering timpani heads: QUESTIONS TO ASK: What BRAND/MAKE drums are the heads to be used on? This refers to the "manufacturer" column listed on the far left of the Timpani Head Reference Chart. For example: Yamaha, Adams, or Ludwig. What MODEL/SERIES drums are the heads to be used on? This refers to a specific manufacturer's series or configuration of drums. For example: The make is "Adams" and the model is "Philharmonic." The make is Yamaha and the model is "6100." What BOWL sizes are you trying to fit? The bowl size is the diameter of the drum--from bearing edge to bearing edge (from one side to the opposite side). *If you can obtain ALL of the above information from the customer, you can use the reference chart to get the appropriate head sizes. Can I use the part number off my original Remo heads as a reference to order Evans Timpani heads? If the Customer cannot answer ONE or ALL of the above questions, but knows the correct Remo item #, then follow the below item number conversion examples. Like Evans, Remo heads use a 4-digit sizing reference in the middle of their item #. a) If the Remo sizing # is 2200, the Evans equivalent is ET22 ( = 22"). b) If the Remo sizing # is 2608, the Evans equivalent is ET2650 ( = 26.5"). c) If the Remo sizing # is 2712, the Evans equivalent is ET2775 ( = 27.75"). d) If the Remo sizing # is 2404, Evans does not have an equivalent size at this time.

If you cannot answer ANY of the above questions, here's what to do: Step 1: Measure the counterhoop (metal hoop that holds the head on and applies tension) diameter from one size of the drum to the other. Step 2: Subtract roughly 1/4" to 3/8" from the measurement (in inches) they give you. The head needs to fit under the counterhoop, which has an outside wall that's about 1/8" thick on each side of the drum (which is why you subtract the 1/4" or 3/8"). The measurement you are left with should come VERY close to one of our head sizes. That's the one you want. Can I use the part number off my original Ludwig heads as a reference to order Evans Timpani heads? The part number on the Ludwig timpani head is actually a bowl size reference, not the head size. For example: Ludwig heads say 29" Ext. This misleads the customer into ordering a 29" extended collar head. The actual head needed is a 31" timpani head (ET31). The Timpani heads don't fit my older model Ludwig drums. Some older model drums have non-standard counter hoop sizes and require custom ordering. This is not yet an option with Evans Timpani heads. For manufacturers not listed in the Timpani Head Reference Chart, please measure the outside hoop diameter of the original head.
