    +1. A replacement for the tweeter would also be nice. Oh, and a midrange.

      You are correct, I was mislead by the photo and the XO, which says 3

        Back in 2014 I won an Esoteric ES-140 along with a Transducer Labs tweeter at the Iowa DIY. They're both going into a PE Design Team submission that I'll have ready in the next couple of months (ahhh, the masochism that is making that First Generation driver sound good). I understand that the 2nd Gen is much easier to use, but Gen 1 is in the personal inventory, so it gets used!

          Well, not sure if the new versions are actually better. Less sensitivity too. Def glad I picked up a few pairs of the 'old' ES180s on clearance

            I agree. They lowered the peaks but the super smooth response was lost. And the ES180TI-8's peak at 3.5khz was not too bad and a rising response is easy to fix.

            I recall once seeing a post of what direction to go in when technology already allows amplifier like distortions. I say woven cones and cones of beauty. And for tweeters the same but with improved impulse response.

            This is what I would like to see:
            • 4-ohm models
            • The woven cone re-engineered. It's a beauty but the large spike on the ES140TI-8 is a bit tough to work with. The ES140TIA-8 and ES180TIA-8 compromised frequency response smoothness, necessitates a hefty tweeter and very low crossover.
            • Keep the motor design but post the 10khz Le and Klippel data on the PartsExpress site. It proved itself in VoiceCoil but it would benefit from additional info.
            • A woven Esoteric tweeter. It's possible and Transducer Labs managed it with Kevlar and Carbon Fiber.
            • A dedicated mid-range or at least a 4-ohm model with smooth response and no peak. Some may prefer a phase plug but I personally prefer the 3" dust cap for a mid.
            • Klippel and FEA optimized 2" and 3" domes. If possible a woven version although only if the breakup is not as bad as the RS52.
            • Larger Esoteric models, the ES180TI is really more like a 6". The Ultimax's are beauty's but have a very large surround that is not a cosmetic match and have a DVC.

            Beauty shots of mine below, I bought four ES180TI's. I'll post some really interesting reading on cone material but first I need to know if posting a link to a VoiceCoil pdf I found online is legal. Is it fair game?

              The usability issue with the ES180 is that it really needs to be used in parallel and it's more of a midbass than dedicated woofer. And the SD is also under most 7" drivers. Imo its best in a TMM or 3 way with small mid. If the latter, there's a tricky decision of which small mids to match it with, aesthetically and performance wise. Its such a beautiful driver that it deserves a good looking mid!
