If you are feeling adventurous, you could get them made diy, like I did. Mine are huge both physically and sonically. Can blast my ears off, with absolutely zero distortion. I was looking at speakers in the 5L+ category 3 years back, to upgrade from my pmc floor standers. And on a suggestion from a FM, I went down the diy route. I needed a lot of flexibility in the design, with the possibility of going active in the future. So the crossovers for the 3 way design, are external to the speakers. Another criteria which nudged in this direction, is that I like transmission line bass, as opposed to ported and sealed design. So my speakers were designed to exactly compliment my musical tastes, with 10 inch drivers in a TL. If your room is bigger, then the drivers can get bigger accordingly. The absolute limit in my small 11.5 x 15 ft room was 10 inches as per the designer and builder of my speakers. These are a no brand name, but I've been in love with them ever since my first listen.
On the downside, I might never be able to sell them on, as there is no brand weight behind them. So it is not a path everyone will be willing to go. Besides, just beacuse they are DIY, doesn't mean they are cheap. The crossovers alone cost close to 1L to build from imported components. So just an alternative idea to munch over
