I see some interesting small subwoofers on the Tang Band website that Parts Express doesn’t carry. Particularly a
4”x6” subwoofer that would allow me to build a ~25cf reflex enclosure tuned low. I own a pair of Anarchy 554’s, a TB W5 and Dayton Epique 5.5” but all seem to need a larger cabinet to allow a low tuned reflex alignment. Running any of those woofer pairs sealed will allow ~90db @ ~30hz but I loose a lot of headroom making big cuts in the midbass to get a flat response.
I’m shooting for a 27 hz tune, likely with a passive radiator. I’d be building a pair, maybe into the actual front L&R mains or maybe one under each front main on my lamp shelves. I currently have the 554’s in a .23cf sealed enclosure with Tang Band W3 bamboo fullrangers. If I can build a small pair of low playing subwoofers I might use a pair of RS100’s with soft dome as front L&R. The RS100’s would roll off naturally for an acoustic xover of ~125hz.
This is to be used in a townhouse where 90db of bass is about the maximum and I’m pretty sure the Kartesion Sub120 or one of the smaller Tang Band units would get me there. A pair of 4” Dayton TCP115’s with 5” passive radiator theoretically gets me around 85db at 3/4 excursion (4mm total xmax) but I’ve seen measurements showing high odd order distortion below 100hz on them.
I build all my audio toys small as there’s just not enough room for even .5cf cabinets to look like they fit in. Also if my girlfriend sees larger speakers she thinks everything is always loud, if she sees a compact setup magically it’s not loud 🤷🏼♂️
I enjoy the challenge also, I love the idea of a pair of smaller bookshelves that play low and get just loud enough to start bothering the neighbors. And, a pair of .5cf reflex enclosures with a long throw woofer model up to like 100db below 30hz which is just asking for trouble if I’ve had a few.
Thus a pair of ~.25cf cabs seems appropriate. The Purify 4.5’s are way out of budget. I’m very open to learning about any other brands offering small low fs drivers with good xmax.
Thanks in advance

I love the Sub120 but the E150HE should kick it's *** in output, even in 0.15cf sealed. I guess you can put a Sub120 in 0.2cf with some PRs to reach 30Hz but that just doesn't seem very efficient use of space to me unless you're limited in power. I'm not sure how headroom works but do you really lose some if you Linkwitz transform the E150HE?
I hope you're not thinking about the Sub120_vHE - that thing is just too sexy to be used 🙂

You’re right jaak, theoretically, the Epique 5.5 and Anarchy 704 sealed in .22cf win with both pairs hitting ~95db @30Hz in winsld. The Anarchy 554 and Sub120 are also tied with each pair modeling at ~90db @ 30hz. The difference between the 554 and 120 is in .22cf the 120 needs ~125g on a 7” passive radiator to achieve it and the group delay shoots way up there around tuning.
I could spend over two hundred plus another sixty on new cabinets on two 120’s and not have any improvement, and potentially loose performance because of group delay. Or I could spend a hundred bucks and get another Epique 5.5” and have 5db more 30hz. Would be really fun to bring my shop loudspeakers into the house, a pair of Anarchy 704’s, and Dayton 8” reference series passive radiator in .5cf capable of ~105db @ 30hz.
For reference I model everything at about 80% xmax because that’s when it seems klippel tests tend to show a limiting factor in linear excursion so I just ball park my modeling around 3/4 or so excursion to be safe. I’m also fixated on the 27-30hz range. I’ve found that when I listen to synthesized music the lowest notes tend to dip just below 30hz so it’s a requirement in my builds. I also build my amplifiers with mostly Dayton KABD dsp boards.
