@Adi777 I did get a green light to post a reply from

We will see how this is received by the masses.
This is exactly what I wrote for the dm.
Hi there.
As a business I exercise a very strict code of conduct and will only contribute to a thread by guiding and informing only. I will never endorse or tout my own wares on a topic that people are working to discuss and assist. And so I will answer your question here. I hope I have gained your respect for that stance.
The differences in performance levels is found in the performance metrics in our website. I realize that this info is incomplete at the moment, but we are working to fully analyze the data and publish complete metrics. It is mega lots of work and keeping up with manufacturing demands takes priority.
The place to start is by reading the whitepaper on LDLC and the associated materials published on the website. This will get you into the mindset of what we consider to be and make up audio output. The cliffsnotes is that output heard = (clean output signal + compression + distortion of all types, of which there are multitudes) to the power of efficiency. I cant find a superscript function in the text, so spelling will have to do.
What I can tell you is this:
All subwoofers use the same underhung motor topology. However the BL and other metrics change and this is seen on the very end at the performance level. Using end use performance as per LDLC is the reason we can get 130 dB in content (John Wick gunfire at 30 Hz) without audible distress from a C18 L1. There is a youtube video of it from our client.
For both 18 and 24 inch models:
The bottom end 5 Hz mark "with authority" means that the bottom end is clean and strain free. This does not mean "flat to 5 Hz", this means competent and as such the harmonics produced will not affect the higher and audible frequencies. This also means that the output at 5 will follow the trajectory of the roll off, and this is very important to know and understand.
The baseline representation for all subs is the enclosure is made from a carbon/baltic composite. The carbon is a structural member, not a finish. The finish is clear satin lacquer and other finishes are available. This composite structure cuts resonance down by around 30%. over wood or paint finishes.
- The L1 represents the best "bang for buck" at the LDLC level with very clean output but is down on overall output ability.
- The L2 boosts output ability and increases power. This is not simply "strapping a bigger amp", the motor has to be built for the task and so the motor and driver is different.
- The L3 takes the enclosure to the maximum and furthest we can take it in the expression of cutting resonance. So we truss the enclosure with carbon, and this results in about 75% reduction of resonance over the same enclosure in paint or wood finish. We then put the motor on steroids and increase the BL by 75% and increase amp capacitance by 50%. The L3 is an exponential leap forward and upward on the fidelity trajectory that we establish with the L1 and 2. So it is not for the faint of heart. They are currently used by video game developers for realistic gunfire audio and a sound studio.
I hope I answered your question well.
If you have any questions please let me know.
