Going to be hard to have any real midbass doing what you want. Best you can do is pick an efficient mid that can play low like the B&C mids. You can have some midbass if you EQ up at lower volumes, but you are going to have to back off that when you crank it up as PA drivers dont have the XMAX for a lot of excursion. When I see reviews from people on certain drivers claiming good midbass, I have to wonder if they even know what midbass is. A 3 way set up would be ideal, but you are getting into a very difficult task to pull off then. I prefer my set up to be underlapped. I have found you get a frequency boost between the HP/LP so to me it sounds better with some gap between the mids and tweeters. I have never set crossover points at 2000 for mids and 2000 for tweeters for example. Way too bright for me at that frequency and those above and below. I set them a little apart from each other and change the slopes to blend them. I may get put in my place with with my comments by people who know more about it than I do and thats ok, I am always learning. That is how I set it up tho. I do not have horns, i am running B&C mids with super tweeters and I have it sounding good right now. Not great mind you, but loud and clear and that was the goal. The ST's are too bright and i have to back WAY off the gains and level to get them where they sound ok, but they were easier to set up than horns and MUCH less money. That said, I feel sure in the near future I will buy some horns to try in my truck too. Too many people have good things to say about them to ignore. However, to say you cant have a decent sound without horns is false. It is not plug and play and requires work, but they can sound good with some effort. Flame on.
