No product recommendation but just a word of caution: if you care about violin timbre, play very close attention to crossover component quality.
I'm speaking as DIY hobbyist who has played the violin for 30+ years and mostly listened to violin music for 25+ years. I found that sometimes with $20 tweeters, when you use good capacitors, inductors and resistors in the crossover, they can still do a decent job with the string / rosin / wood body texture, but if you have a $200 tweeter via a cheap passive crossover, the textures can be washed out easily. Polk for sure use very cheap crossover components, and some $5K audiophile speakers use cheap components too. And it's not just the capacitor that matters - resistors and inductors affect violin string textures significantly as well.
