Hey everyone,
Looking for some guidance because both of our old EV MTL-1 subs died this week—thanks to someone getting a little too confident and disabling the limiter on our DSP 🤔... so now we’re in a bit of a rush to find a solution.
For now, the plan is to grab two modern 18” woofers, throw them into one of the MTL-1 cabs as a temporary fix, and then start building proper new subs as soon as possible. Not too worried if the sound isn’t perfect in the meantime, since those drivers will eventually go into the new build anyway.
We usually play bass music (sometimes punk) to crowds of 50 to 200 people, both indoors and outdoors. We’re not after an earth-shaking, rave-style bass setup—just something clean and kind of flat, but with a bit more low-end extension than the MTL-1. I’m also considering building two single 18” subs instead of another dual-driver design, since modern designs seem way more efficient and might even outperform two MTL-1s with half the drivers. Thinking of something along the lines of an L-Acoustics SB18. But we can still be interested in dual-driver design...
Our tops are bi-amped EV RX 115-75s, and I’ve got some great people around me who know their way around CNC builds. The only thing is, their experience is mostly in dub sound systems, which is awesome, but not exactly what we need for a multi-genre PA. They can build solid subs, but I want to make sure we go with the right design that works well for bass music, but also other live style of music (punk, rock, etc).
I’ve searched the forum quite a bit, but I haven’t found a good breakdown comparing modern sub designs for this kind of setup. If anyone can recommend solid designs or point me toward helpful discussions, I’d really appreciate it!
Thanks in advance!

Not hard to do, most of the internal space of the MTL-1 is wasted on the horn portion which starts working at around 90Hz.
-10dB at 45Hz, and only ~82dB sensitivity at it's Fb (box tuning frequency) of 38Hz.
The L-Acoustics SB18 uses a driver like the B&C 18SW115, which has around double the excursion of the EV DL18MT, so one driver =2.
Given enough power, it could step on the low frequency output of the MTL-1.
The Keystone sub is around the size of the MTL-1, but has good response down to ~37Hz using a single B&C 18SW115-4.
A pair of L-Acoustics SB18 would have a bit more output.
