Duly noted, thanks - that will have to be tried out for further assessment.

Is this for mid-bass or ULF?
Actually it's more of a mid-bass driver (certainly no ULF) that lilmike has informed models very well in the Microwrecker. But the thing is, a tapped horn can take such a mid-bass driver (that models well in the given tapped horn) and turn it into bass monster to around 20Hz (give or take, depending on the specific TH), while maintaining the sensitivity of the drive unit. Other tapped horns, like Danley's TH-115 (where the B&C 15TBX100 is also used) don't go as low, but in return will sport a higher sensitivity. You go sub 20Hz with a tapped horn and you start eating further away of the sensitivity, and horn size increases rapidly. So, for music/HT use the M-Wrecker seems like a good compromise in terms of extension, sensitivity and sheer size.

Now, If you can build 2 of them and get them in different spots for even room response youd be hard pressed to beat it.
Notfastenough built 2 THT's with ultimax drivers and im not sure if his house is still standing or not, but he seemed to be very very very impressed and pleased with them.
Another guy had 2 lilwreckers and could make vision blur.
So where I ended up, and I hate to keep bringing up these darn JBL 12's...but im running 4 12's with 4 more about to go in and Im way happier then just the single 15 horn. IF I had the space I think I wouldve built another horn, then stack them on top of eachother and have them facing opposite directions behind my screen. Im keeping mine because down the road I just may use it if I find myself with a bigger house.
So basically my thoughts are you should add another sub if you can, 2 subs is still better then 1 horn in my eyes unless you really really dont care about only your listening position. Me...If I have people over I dont know where ill sit, and I dont want to give them the seat with no bass, and I dont want to sit in it myself lol. This is what multiple subs vs one sub is great for.
Yeah, point taken on using two tapped horns, and not just one. It's not impossible in my listening room, just.. well, darn imposing. I'm still thinking to possibly start out with one, and then see where that leads. And thanks for mentioning Bills THT(LP) - actually I've been looking into that one at an earlier juncture, and I'm sure it's a very capable bass horn - feedback is certainly positive. For my temperament though I've settled on the M-Wrecker, as it seems to bring some qualities to the table that I find intriguing. It's indeed crazy what a tapped horn can supposedly do with a single 15," or a smaller unit for that matter, like with the Pico. That's what really amazes me, that such a horn can unload the driver in a sense and take the heavy burden off it. All the more reason to expect that effortless bass quality, while effectively setting in motion much more air than the drive unit alone (i.e.: as a direct radiating unit) would be capable of.

Coming from a guy that put 2400wrms on two RE audio SEX12's in a large dual opposed sealed box (to keep it from walking off). I replaced them with dual picowreckers from lilmikes design pdf (only two little 10" sws alpines). They do so much more than you'd expect and on 1800wrms. The 12's would strain to fill more than half the garage space I use this in (32x36). The pico's have no problems at all and extend outside to the carport
to rock when washing cars etc. Just giving an idea.
Agreed as posted above take the svs cube and place it where you plan to build a huge TH footprint and see the response. I'd say if can stack or get them in there do duals as well. Make sure have a HPF and enough power ie inuke or ep4000 (950wrms/channel for each sub; dual 2 ohm coils wired
Welcome to insane output from relatively small footprint. Hey it's smaller than a array of subs
and that is efficiency.
Oh, no offence taken. Please, throw the gloves, people, and let me learn of your honest oppinions
I need that kind of feedback to get a bearing on the difference between my SVS and a tapped horn, being that I have no experience with the latter. Conversely some may advice me to run away screaming from a tapped horn, but, too late

, look at bill fitzmaurice's web site and find the THT and look at the THTLP. Square foot wise, terrific bang for the buck. No HPF needed, and a known build in the DIY world. Build as wide as space permits.
Perhaps with these stood on end, you could place a pair of them. No one is steering you wrong by suggesting a pair in separate locations. And horns LOVE corners btw.
If crossing very low like you suggested, they could be in the back of the room and your ears would be none-the-wiser. Just a bit of delay needed (which is an absolute necessity thanks to the horn length anyways).
Honestly, for the most direct answer, details (constraints/compromises) about the room will help the most. Pictures are always welcome
Thanks for recommending a different placement of the TH. Will a (mini-)DSP be able to apply sufficient delay? And regarding the THT; thanks, but per above I've settled on the M-Wrecker
Actually Josh Ricci's Othorn (tapped horn with a 21" B&C unit) also appeals to me, but that sucker is a true monster and likely way way WAY above my league, so to speak
I'll get back with more details about my listening room

Oh, didn't I miss a reply above on the same question? Well, sorry - didn't intend for that, but since it's asked here as well. Cables? Well, main speaker cables are a shotgun combination (single-wire termination)of 1.5mm Mundorf Silver/Gold solid core wires and Duelund DCA16GA. IC's are KaDo RCA (Danish cables), and power cords are DIY twisted 1.5mm solid core copper wires with pure copper IeGo connectors. USB cable is Wireworld (can't remember the model name), but that one's likely up for replacement sometime in the near future.
A picture of my setup attached.
