Stimbo22, most horns (Khorns included) have high efficiency drivers that, because of their efficiency, are also highly reactive. Such drivers have a lot of back EMF because of the greater precision and efficiency of their magnetic motors.
The back EMF really messes with amplifiers have a low output impedance. However the passive crossover of the speaker is helpful, because it is a series element in the speaker, and so allows you to use amplifier with a moderate output impedance (at least) without too much trouble.
If you get rid of the passive crossover, the only amplifiers that will work well without being excessively shrill (due to the interaction with the back EMF) will be ones that have a high output impedance.
The S-30 is one of these, as are a number of smaller SETs. So you *could* make that work, but OTOH you could have a slightly larger amplifier and the passive crossover, and it might work every bit as good, with a lot less complexity and a lot less invested.
BTW if anyone has ever wondered why transistors are often shrill and honky with horns, this back EMF issue is why. I should point out though that the back EMF will mess with any amplifier that uses a lot of feedback.
