I am surprised there are not dozens of LHorns built already, especially when they make great couch tables or TV stands or ???
honestly, probably because there aren't a lot of Ghorns around either. it's a BIIIIIIIIIIIIIIIIIIIIIIIIG build that requires an expensive driver... that and the fact that you're the only one who built one and people tend to go with the ones that get a lot of traffic. that's my suspicion at least

It seems as though my quest for more BASS has come full circle...... Plan "A" was 2 Full Martys with the UM-18....... then I found the Liiwrecker........ then I found the LOWARHORN..... same size, more output... sweet!

I thought that my quest was over UNTIL....... I found the beast called SUBMAXIMUS. Funny enough, SUBMAXIMUS is just a hair larger than 2 Full Martys.

Please correct me if I'm wrong..... SUBMAXIMUS has MORE BASS OUTPUT from 1 less expensive driver (SI HT18) than 2 Full Martys with UM-18's.

How did I get the wife to agree to the SUBMAXIMUS you say....... I have to build her this FIRST! http://www.tantrachair.com/wp-conten...88978879821252
Plus it's also a side benefit for me ......

So fear not my friends......there WILL be another SUBMAXIMUS before the end of summer!

^
check the dawnings of the MAX evolution to see what the designer decided upon, iirc not too enthusiastic about the SI 18 but not undoable


tantra chair "looks" simple but isn't this one of "write the check and get down to business things"? anticipation is one thing but . . .


MAX comes to about 38 ft3^ mol


you have my attention

@asarose247:

I have read through the thread several times, the consensus was that the SI 18 was just ok...... I'm looking to run a sim of the FAITAL PRO 18HW1070 to see how it fairs in this box. I have used it in PA rigs 25Hz+ tune in the past with great results.

After my reverse engineering was done..... the frame is a WAY easier build than any folded horn...... the PITA will be getting the stitching correct for the seams of the cushion on top. Once the cushion is taken care of, I could be finished in a weekend.

Ya, definitely on the large side.
I would say the driver is cheap, but it is all relative...I am used to $900 LMSs. With the group buy and under $400 that is ton of driver for the money, especially since in the LOWARHORN it would best multiples of cheaper drivers in other enclosures, it really is more economical...IF you have the space.

I agree on the traffic. Once another gets built I am guessing the interest will pick up dramatically.

tantra form easy to make, accommodating padding , trickier
what about lots of multi layered foam/denser foam/bed topper foam
and then instead of a form fitted cover, a real accomplishment in itself . . .
a removable cover, just needs to be "close', not so "exact"
you can use/attach adjustable straps, attached away from the action, for tautness, keeping it mol in place, have them pass underneath, or thru some holes cut near the bottom , pull straps thru and take up the slack, not necessarily from Harbor Freight, but you get my drift . . .
a new product line for HF?
Eureka! By George, I think he's got it!
a cover made of something smart, like they use in the liberator pillow . . ., removable. washable , wipes down well . . . ripstop nylon comes to mind
TMI?


and maybe/sometimes an extra coverlet or a nice fuzzy/snuggly towel . . . just to top things off
YMMV
LOL


pictures or it didn't happen
I'm just sayin' . . .

yeah, once theres like half a dozen builds it'll start taking off, especially with the rash of UXL 18s coming from the group buys

Is the HPF based on pushing the driver with 1200w? What if it were only 600w? 300w?

Quote:
WARNING: A high pass at 13-15 Hz is REQUIRED to protect the driver.
Here is the excursion with only 1200w:

As shown, the driver unloads quickly below ~15Hz.

The graph was based on 1200w.

The lower the power the lower the excursion, but a high pass filter is recommended on most designs.

Yes, if you have a very capable driver and only feed it 500w you could probably get away without out, but why live dangerously?

You will need some form of EQ regardless...just apply the HPF and mitigate the possibility of damage.

Understood, and your assumption is correct. Just clarifying so we are all on the same page.

Hey Brian! Welcome to AVS!

You might want to subscribe to the Dueling Lowarhorn build as well. It is more active as the build is currently in progress.

You don't realize how big these things are until you start pulling out the measuring tape in the seating room. I thought it would be cute to put one in my front room as a couch table but 24" is a bit big. The wife just looked at me funny. Honey I can cover it in shag and see if it puts you in a better mood.

Ha! Yes, they can be a bit large, especially when you are not used to larger enclosures. It's like most things though, after you get used to it you forget about it. I put a table cloth over mine and it works well.
