In that situation a piezo tweeter might be worth trying, they cost pennies and don't need a crossover. The down side is that they don't sound great but if they are just your personal monitor for the synth they might just give you enough to save you spending a fortune. There won't be a huge effect on your bass sound either. Power handling isn't great, they are usually rated in the maximum voltage they can handle 25-35V rms which equates to around 100W at 8 ohms, synth puts out a lot of power into the horns. The simple solution is to wire two in series ( I can hear Stevie and BFM flinching here as this is sooo wrong acoustically) It will work though
I've got a box full of these in the loft , if you want to try and are happy to pay postage pm me and I'll send you a couple gratis. you can try them just resting on the cab and build a box after if you are happy with how they sound.
