Given that you're from Spain, and want a subwoofer for music, i would suggest two sealed 125L boxes with a BMS 18N862, you should be able to get each for about 600€/650€ in Spain.

Sold, please close.

For sale, the driver that's considered the best subwoofer driver in the world, the mighty LMS Ultra 18". For details, please see the data.bass.com review. They were bought second-hand on July 2018, but due to several constraints, i didn't had the change to use them, they are boxed since that time. I only mounted them to take a free air REW measure to confirm that everything was OK when i received them, and then, they were boxed and stored. One of the subs has very small mark, as can be faintly seen in the first picture, but its very very small and without any impact visually or

I've modeled the B&C 18" ds115 - 8, and unless i've made some error, it seems that it only needs very small box to achieve a 0.707 alignment in a sealed box. That's a major benefit when comparing with the other similar drivers.

Which would you choose between this B&C (or the 18" version) and the BMS 18N862 for a sealed subwoofer in a 125L box? Are they more similar than different?

In Europe the situation is the inverse. The BMS can be bought by 650$ and its widely available. By contrary, drivers like the HST18, UXL18, etc, are much harder/expensive to get. Taking this into consideration, do you think the BMS is a good alternative to the UXL/HST ?
