I am confused... are the lilwrecker and the microwrecker the same thing?

I can't find the microwrecker anywhere.

Also - Has Mike said why he likes the wrecker over the f20? I thought folded was better then tapped.

Not the same thing. I don't think lilmike started his own thread for the micro. Try here.

The Lilwrecker is a folded horn and a tapped horn. The f20 is smaller but doesn't go as low as the Lilwrecker.

Not as active on the forums as I used to be, sorry. No time for speaker R&D like I used to, and certainly no time to deal with another design/build thread.

The thread that was linked a couple posts up is the only place I've shared/posted the MicroWrecker plans on AVS, it is still very much a work in progress with me, it is just that I haven't done much work on it since I finished the test-build (not because it's that good, mainly because I've been that busy with the rest of life).

Rather than try to find a way to get it properly measured and tested, analyze everything, then re-fold/refine a few things that I'd like to change, then rebuild it and test it some more so I could present the finished product, I figured that I would share the interim plans I have at this point if people wanted to play along at home. The plans in that thread are current as of today. A couple ideas about things I want to do differently, but as yet, I've not changed a thing. When I posted them, I decided that it would be far easier for me to attach a file to a post here rather than distribute them via emails like I had been doing.

The MicroWrecker is much smaller (~20 cu. ft.) than the LilWrecker (~30 cu. ft.), it gives up a bit of extension, but it does get a bit louder. According to my measurements, the Micro's tune came in at 22 Hz. vs the LilWrecker at ~17 Hz. I don't have groundplane SPL measurements for the Micro that I 100% trust yet, the few measurements I do have for the Micro weren't done in ideal settings or conditions.

As far as preferences? Sure, I have mine, they may not be remotely close to anyone else's. This is audio after all, everyone has an opinion, and when it is your room and your speakers, who am I to say a thing if mine is different? For subs in my systems? I've tried a lot of different drivers and alignments over the years. Currently, I prefer the sound of a properly-done tapped horn over the other alignments I've played with, but that's just me, for now. I'm sure that there's someone conjuring up an even better way to make bass, we'll see what they come up with.

There is a technical reason that I prefer tapped horns vs. front-loaded horns when used as subs in a theater though, similar to ported boxes, there's an excursion minima at the tapped horn's tune. The cabinet is handling the heavy lifting at the low corner, not the driver. Nothing's free though, just like ported boxes, they unload below tune. I can deal with that via a highpass.
Mr.Tim and Michael Mitten like this.

Ports compress unless they're huge, and when they're huge, the build isn't simple.

Killing me! ha... not sure what port compression is. Had big subs so maybe I never experienced in recent memory. Before I got bigger subs I nearly killer my HSU VTF-3 though ha

In a nutshell, the port has to be large enough to function as a port, not just be a leak in the box. It has been my experience that more displacement requires more port area for the same tune.

There's quite a bit of discussion out on the web, as well as plenty here if you look for it. No point cluttering this thread up further.

Agree

I appreciate hearing a differing opinion.

Ported is the fad right now but horns have a reputation and it's great it hear from someone who has a great understanding of horns.

"You need large ports to move lots of low bass without port noise or compression. With the HO, we went to dual 4" ports, which nearly doubles the port size compared to the VTF-3 Mk 2."
