They do not require additional amplification; they are plug and play, having an internal high-pass filter within - you just connect them to the input binding posts of your existing speaker and they will take what they need from the signal. No direct experience to pass on, but it may be less expensive to get your hearing checked before you drop that kind of cash on a tweeter that has a lower range that ends at 15khz. I'd wager that many folks cannot hear that high, in which case I wonder if would make all the difference the reviewer claims. Usually, when integrating a driver into an existing speaker design you also want to make sure the sensitivity is similar to your existing drivers...in this case the driver has a 90db sensitivity. I wonder if, in the range it is reproducting, if this may not be as big an issue since it is being marketted and sold as it is.
I can't help but laugh looking at them as they remind me of those "Deer Whistles" they sell to mount on vehicles to scare away deer so you don't hit them in the road...the kind human's can't hear at all. The debates around those on the car and motorcycle forums may even be similar to what comes up with these things...the emperor's new clothes look a whole lot like his birthday suit!
