I wanna build a system that suit the music mentioned before. 18" subs, thinking about 10" or 12" for mids and whatever I need for tops

As a reggae enthusiast, I first thought of super scoops for subs, but after some research I found out some hog scoops might be a better choice for it's cleaner and deeper response.

For mids I'm thinking of a sealed enclosure for punchy transients.

Last but no least, , I'm really into multicell horns or just big classy horns for tops.

So my questions are basically for the mids/tops.

1. How can I search for that multicell (or not) online to DIY or buy them (not as expensive as some vintage ones I've seen).

2. What's the best suit for the mids.

To sum up I think I know more or less what a want but I don't have the technical knowledge dive into the build without some advise from the pros.

I'm aiming to have a clean sound, with that low frequency rumble, not ear fatiguing and scalable.

Thanks in advance
