Ashdown Rootmaster RM-414T or something else? Lightweight cabinets only. Budget 500-600 range

The Rootmaster RM-414T offers 450 watts at 4ohm and is only 47ish pounds.

I found a local Markbass New York 122 for around that same price, but it's a 212. I play post-punk and some punk. I'm old, female and can't stomach lugging around the refrigerator on an upcoming tour.

I use a Mesa/Boogie D-800+ amp (400 watts at 4ohm, 800 watts at 2ohm)

Are there any other lighter weight bass cab options I should look at in this price range? Looking for most bang for buck that will play nicely with the D-800+
 
I had the same head and now have a Mesa WD800 into a couple of single Subway 1x15's . Both are excellent amplifiers. They pair extremely well with the Mesa Subway line of cabs. The cabs are a little pricey, but light, powerful, sturdy and sound great with those heads. good luck !
