Most of you have heard me refer to my DIY 15" Neo magnet subs. Here they are, all 48 pounds (each) of them -

They are High-Passed at 40 Hz, and are driven by a 7 pound(!) Behringer iNuke NU3000. The NU3000 can swing 49 volts on it's outputs before the sine-wave starts to flatten (clip), which equates to a true 300 watts RMS at 8 ohms. I've heard lots of Behry stories - this amp has never let me down.

When I was younger, I was keeping my eyes out for a pair of Carvin LS1801N 18" passive subs being sold locally. 53 pounds (also neodymium magnet)!! I've never heard of a lighter 18, but too heavy now.

I use a hand cart to move them. However, there are always instances where they must be lifted, and I'm finding that even though only 48 pounds, my 73 year old body would prefer something lighter.

They go to every gig, and they sound wonderful. A quote from a Bose ad - "I'm going to buy two more B2's for max bass thump. Club owners like the great tone at Lower Volume Levels." Yup!! Bottom line, I'm not going to stop using subs.

For max sound quality, I built them from particle board, so I may first try 5/8" Birch Plywood. If they end up around 40 pounds and still sound good, I'll be golden - the tops I use are 20 pounds, so the tipping factor is not too high.

However, I'm open to other suggestions - active or passive - in the 35 to 40 pound range. Any ideas?

I really like the sound of the RCF 7xx series subs. The 705ASII (15") is a bit heavier at 63 pounds, but the 12" version (702ASII) is in at 43 pounds.

The downside to too light of a sub means you need to be very careful if you pole mount tops of some weight. If I was to go to a very lightweight sub, I'd make sure it laid flat, with the pole mount on the side so the tops had a better chance of staying upright.

Pole mounting looks good; certainly symmetrical, but that’s not necessarily the best way to deploy them, as I know you’re aware. But if @Handinon is set on smaller, lighter subs, he may need to couple them, and/or corner them, just to get the same kind of tone he got with his larger, heavier subs. I used some 15” subs for years (a brand Handinon would not likely buy), and I almost always coupled them to get the best BOOM!

Per feedback so far, I may go in a completely different direction - 10" Horn Loaded subs. Laid on their sides, they have a 24" x 24" footprint for stability, use an $80 driver, and weigh 35 pounds!
