Eminence Kappa-15LFA 15" Low Frequency Driver 8 Ohm
What is the best repl. driver(s) under $200 for the JBX 125?
I recently upgraded the horn drivers with the Selenium 220ti. The highs have improved so much that the mids & lows are over matched. I've pulled down the mid freq. (1k +&-)in the EQ because it had that megaphone effect. Lows are weak. More low EQ just sounds boomy & muddies the sound, no punch. JBL says the JBX is a "quasi" 3-way. Not quite sure what quasi entails. I find several drivers I like, but which one? Do I repl. all 4 with the same model driver so they work together? or Can I use 2 LF drivers to get better lows & 2 quality mid bass drivers to punch up the mids? That quasi thing is messing with me.
Let's take this one bit at a time. When you change a driver - you have to consider the efficiency of each one. So the Selenium may sound better in its range - but can effect the overall balance of the system and make it sound bad. If it is more efficient - you need to pad it down if there is not an "L" pad for the tweeter output. That would account for the apparent low bass output. You may be over-EQing and under amplifying... You especially need a lot of power when using EQ for DJing. As for replacing all the drivers - don't. If you don't like these speakers - sell them and either buy a speaker you like or build something from scratch. Finding woofers to fit the cabinet etc and a full crossover redesign would be very cost prohibitive and a compromise not doing it from the ground up.... And now - here's how the quasi thing works... Both woofers cover the bass range. One woofer is rolled off in the mid-bass range, and the other is rolled off higher to allow it to function as a midrange as well, crossing over to the tweeter. Very common design. If you correct the level on the Selenium, have the right power and use your EQ correctly - this system should sound very good.

Any thoughts as to this speaker vs a CB158 for a ported Ampeg B115 cabinet? This speaker seems to spec out a little better for 10 more bucks
This speaker surpasses the specs of the OEM. I replaced 2 - 15" Ampeg V4B speakers with a similar Eminance speaker and they did very well. My opinion is that you will have an upgrade in sound quality but a very slight decrease in the 134 spl.

This speaker can be front loaded right?

can this speaker be loaded in a sealed cabinet or horn loaded cabinets
This driver is best suited for a vented cabinet.
