Resonance Speaker 50mm 2Inch All Frequency Resonance Loudspeaker Vibration Round Strong Bass Vibration Louderspeaker(4Ω 25 Watt)

I bought two of these for my Fanatec CSL pedals. I wanted a realistic feel so the vibration is turned down pretty low but they replicate the feel of the road as I accelerate and brake. I’ve used them for two weeks now with no issue. My only feedback is that the red and black wires that come with the speakers are incredibly thin and are very hard to splice into larger wires. I had to solder and heat string over the connections to ensure they wouldn’t come loose. Other than that I think they’re worth the price if your looking to add haptics to your simulator

The flexure broke after 1.5 months of use, only running the transducer at 25-50% power.

Unit was shipped in bubbles in padded pouch. I don't think this would be an issue except that the output platform was attached allowing the spring to be over-compressed and slightly bent. I was able to straighten it and it seems fine so far, but if the two pieces had been shipped disassembled, this would not have happened.

Used it for surface speaker
