I doubt it because unless I can see equivalent measurements from every other speaker in existence, your claim cannot be validated.
Does that seem logical?
Perhaps you could put this out as a challenge out to all your competitors?
Flat to 25Hz is pretty poor by today's standards, especially for the money, my three ways play flat to 20Hz, are sealed and cost significantly less.
But even they couldn't satisfy my bass needs so I have two largish sub-woofers doing below 80Hz duties.
Every product has compromises, something has to give.
