Hello,
which is the most sensitive / loudest 1x18" design, regardless of size or speaker, 30-120Hz roughly ?
I wonder which one it is, Martin audio ?
cheers

For this, I'd get the PA 18" with the most excursion and power handling available, and put it in a massive horn.
I ran a Faital 18XL1800 through Hornresp to see what could be done. With a very large front-loaded horn, it'll crack 144dB at 30Hz. 35Hz is excursion-limited to 141dB, and above 40Hz, you're passing 145dB.
These are all single-driver, ground-plane, with a large amplifier. You lose a couple of dB at 30Hz if you limit to 3200w.
The down-side, of course, is the size of the box: 8366.5L, or 295.5 cubic feet. Hey, you did say "regardless of size".

Hi Chris,
well that is something, i am ideally looking for graphs of already existing Subwoofers, i have mad a promising measurement yesterday and i would like to know if i can keep up with the best Subs out there. I will post my graph as soon as i get back to the PC where it is located.
its a large cab, 129x60x92 cm and loaded with 18" IPL BandC speaker.
i wonder if there are any Danley 1x18" for example that somebody have made 1w/1m SPL measurements ? Or any other ? Looking forward. greetings

Sensibilité : 107dB 1w/1m (2.83 volts / 8 ohms)
High pass: 33Hz 24dB/oct Butt
have free plan in his site.

Perhaps a car audio driver with sufficent power handling and excursion and a huge amplifier could beat the Faital at the 30Hz point by using its greater excursion capability. I would link to a driver on databass but the site seems broken, very expensive though!
