I'm not very familiar with BFM subs, but the designs that I've seen seem to have poorer frequency response (FR) curves and other performance parameters relative to the F20 design discussed here. I always recommend placing subs in the corners of the room, just behind your front mains then EQing the whole lot to be like one loudspeaker on each side to get ~flat FR down to 20-25 Hz. This will dramatically reduce the harmonic distortion at or below 20 Hz shown in the graphs--assuming that the author was testing in half space outside on the ground when he generated the plots shown in his build thread.
Your ears will like the results, I believe.

To say one is better than the other depends on cabinet width & driver compliment.
There is only one design for the F-20, the THT has many build options.
Different drivers work better than others depending on how wide you build your cabinet.
I agree with the others here about a tapped horn not being able to match up well to the La Scala or Belle bass bin, tapped horns get distorted before meeting the ~100 Hz cutoff point.

I prefer pie charts over graphs.

Happy Birthday old man.

Worth every penny.
Upgrading to the bigger MCM ?

True, not cheap.
Ever try cooked cheese? Try it in a pan that does not stick, cook it until the oil is gone and it's crispy.
Ok it was an accident when making the grandkids grilled cheese sandwiches, it was good so I threw in more cheese to do it again.
I do the same thing when making quesadillas, cheddar works great as does mozzarella.
Not sure if cooking the moisture out is healthier or not but it sure is yummy.

Throwing the phone in an empty cup works good too.

Its not just Ford, GM & Chrysler are no different.
Shyt rolls downhill and american car makers treat the ones who keep them in business like trash.
If it was not for american loyalty the big 3 would all be out of business.

Growing up listening to horns everything else sounds bland.
Horns deliver realism and minute details that other types of loudspeakers just cant deliver.

We got recall bulletins every day at the GM dealership.
Possible Dave works at Ford, knows somebody who works at Ford or found information on the subject on line
If i recall customers were only notified if it was a safety concern.

Good catch Dave. Loose pin will do it.

Sounds like a bad ground or something wrong with the head unit.
Normally a bad ground would make the noise through all the speakers at once but its still possible to only happen with one.
Try to keep a log of when the problem occurs for documentation and if you could capture the issue with a recorder (phone or whatever) even better this way you have a fighting chance for a free repair if your warranty expires.

Happy 4th of July.
Don't blow off any fingers this year.

Theres not enough information on the websights to determine the differences.
You would need to do a side by side comparison in the same space to tell witch is better suited to your ears.

If it needs to be lightweight check out the Bill Fitzmaurice Simplexx 15HT sub, it uses lightweight braced plywood construction, corner ports to reduce cone rock and will offer plenty of output for your room size. Its a DIY sub project but there should be a cabinet maker near you.
The weight should be near 1/2 of the others mentioned, it uses the Dayton HO 15" driver
Here is some info.

If your budget is tight and you need some bass check out a basic subwoofer kit & amp from parts express.
Add a can of primer, a quart of Rust Oleum and a good brush and you're all set, under $600
You could add 3 foot long 2" ports to the cabinet and it would get you down to ~ -3dB @ 27 Hz
Sealed version would be ~ -3dB @ 45 Hz -5dB @ 35 Hz

No need if you're not bi-amping.

Go out and audition as many models as possible, what sounds good to one person may not be right for another.
-
Much would depend on your application and room size.
If you plan on using these for pro sound usage the minimum i would recommend would be a pair of 15" or a good 18" professional subwoofer.
For home audio much would depend on room size and if they would be used for music only or home theater application.

Now that's a good looking bike. For the record I've driven lots of dirt bikes growing up, as well as couple street bikes when I was 18 and also ride my dads Suzuki Bergman on the regular and am very comfortable on it (5XX lbs). I am just super new to the cruiser or harley style of motorcycle.
I rode dirt bikes myself growing up, i feel there is no better training for the road and bigger bikes than riding on uneven surfaces, jumping dirt hills and general all out fun riding through the dirt, grass & mud.

Mixing different subwoofers is a bad idea.

2 expensive high X-max 18"s would probably give the THT a run for its money, THT max output is around 127dB.
The THT will offer less distortion and cleaner bass notes.
Depending on cabinet tuning and driver choice the 18"s could dig deeper.
The THT is tuned to 22 Hz, corner loaded should get you to about the same frequency in a large room.
