Getting good sound quality below 200Hz


I run open baffles with currently 15" Eminence Alpha bass drivers with their dedicated Rotel amp and crossed over at 200Hz with 24db slope.

This underpins the upper driver beautifully but by contrast if I play it on its own its not at all impressive, lacking primarily in both definition around the sounds and also impact.

My first question "is this typical of what sound is like below 200Hz"

Secondly looking to improve this should I concentrate on improving the 15"drivers or the amp?

 

Please don’t recommend a powered sub as I have one already which will eventually underpin the 15"drivers when I have that bit right.

Thanks

My system is multiamped and crossed over with boxcar digital filters. By happy coincidence it crosses from bass to mid at 190hz, and I can shut off the mid/high power amps and just listen to what’s below 190hz, which I do on occasion to be sure channelization is intact on the computer’s soundcard driver before I subject the mid/hi horns to possible damage. I don’t have bass horns, but I do have a pair of Altec 421a 15"ers that are as clean and fast as any woofer, and it sounds like mud. Absolutely all definition and location (aka harmonics) from any bass instrument, even a pipe organ, comes out of the horns. With everything on the bass sounds fabulously crisp.
