1299 Ported towers

I recently completed building 2 1299 towers with a slot port, for listening to at the upcoming SE MI GTG at my place and then at @hd0823 place. I’ve posted pics and info about them in others threads, but I think these deserve their own thread. I’m hoping the 40 people coming next weekend can post some listening impressions here for others to get an idea what you get from a design like this. Thanks to @eng-399 for helping model the ported cab, and always answering my questions! Here I go......

1299 Ported towers

Here’s the design. Overall dimensions of 14.75 wide, 16” deep, 52” tall. Roughly 6cf of internal space. For a tune of 30 hz, this requires a 2” slot port, full cab width by 9” deep. I came up with this cutlist and had a local lumberyard cut perfect mdf to size. Note that the back panel sits recessed 1/4” for design ‘flare’ lol.

Top/bottom
[email protected] 14.75 X 16
Sides
[email protected] 16 X 50.5
Backs
[email protected] 13.25 X 50.5
Fronts
[email protected] 13.25 x 9.5
Ports
[email protected] 13.25 X 9”
Braces
[email protected] 13.25 X 14.25 (between back and front panel, below baffle)
[email protected] 13.25 X 15” (behind baffle)


1st mock up.

Cab assembly
Here’s a few pics of the usual glue and screw cabinet building I usually do. Predrilling and countersinking corse thread drywall screws 1 1/4” long. With lots of glue. sanded and ready for the next step

1299 Ported towers

I chose to veneer these with the parts express paperbacked veneer. Walnut. Veneer goes on easy. Flush trim bit and 220 wrapped around a paint stir stick for cleaning up the edges. I used contact cement. Got a little light headed with the garage door closed because it was cold outside. I just heated it up and kept everything shut so I could work. Finished the veneer with waterlox. Three coats and they look fabulous.

On to the duratex. For the seem between the veneer and baffle, I used an old trick. Hung my tape over the edge 1/4” or so, and trimmed it off with a single edge blade for a perfect tape job. Then rolled on duratex, no thinning, with a foam roller.

My listening impressions:
I love these speakers. Where they sit right now they are way to close to the front row. And placement is bad, so close to the side walls, but from the back row the imaging of the soundstage is fantastic. With ‘pure’ mode active, they are satisfying full range speakers for music. Voices are phenomenal from these bad boys. I wish I would’ve just built a third for movies too, because voices are so good coming through these speakers. And they will get way louder then you’d ever need, with clean clear sound. I had a group of friends over last night, and one of them made the comment that these are warm sounding. I told him that is probably because of the subs. So I turned them off. He agreed and changed his mind. They are actually quite bright without the proper placement and treatments, especially without subs. But with all those things being addressed, I am confident these would be end game, excellent home theater speakers. I always wanted to hear them. To the point that I built them. Lol. But I’m not doing them justice with proper placement and room treatment, but hopefully everyone who hears them will benefit from that experience.

I'm anxious to hear people's impressions of these. I'm thinking that perhaps I jumped-the-gun in buying a set of JTR's, when I could have built something just as satisfying for far less money. At the time, I just didn't think I could pull off a LCR build.

Building these was a skill level 3 out of 10. Lol. If you can hold 2 pieces of wood together flush, diy sound group makes the rest so easy. The crossover boards by @mtg90 make the wiring a breeze, the baffles are cnc cut and perfect, the flat packs (where available) are easy to put together and get good results. I honestly think anyone can do it with just a few key tools.
The veneer, well that takes a little more thought.

Still trying to pick out the veneer I wanna go with tho. These will be in a open living room so I gotta try to make them look pretty for the wife lol.

Oh, it wasn't the cabinet building that I was worried about, it was coming up with an assemblage of drivers and crossover that would be truly awesome. Modeling speakers is not in my wheelhouse, but I can build the heck out of cabinets.

Just out of curiousity, where'd you get the 1299 kit? Is it a one-off, or an upcoming offering from DIYSG? Nevermind... found it by using the search (DUH!).

I’m still in debate about 1299s L/R sealed or ported towers w a 1099 C (height issue)

OR

Titan sealed or ported 612 (original) L/R w Titan 612 DC center....

Thankfully have no money so I can ponder away

212HTR's. Though, time (and now, illness) hasn't allowed me to get them in my room. Mostly because I planned a fairly extensive overhaul of my rack when I made the swap... Incoming power, amps, etc.

Incidentally, what are you feeding these, power-wise? I see DIYSG recommends 800w, and the 212HTR's are recommended up to 2000w. My plan was to bridge one of my Cinepro 4k6's to 3-channels for the fronts.

They are hooked up to my gen 3 xpa 7. In stereo they get about 300 watts. But with the 99db sensitivity, I’m only using a fraction of that.

I;m closely following as this is my next build as I am struggling Ported or sealed 1299s..

I WANT (not need) 3 ported with a horizontal center. Eric explained, I wouldn't really need ported as I will have Subwoofers going also. So bummed DIY stopped the ported baffles. Honestly a lot of it is the "Look" of ports. lol So I';m looking to do a Slotted horizontal center and Maybe these towers., or maybe all 3 slot ported with matching center (horizontal). This build looks awesome. I bet they sound GREAT. Cant wait for the GTG impressions. Nothing ever happens around my area. lol

If you KRANK it.. They will Listen..

I have the same situation, needing a horizontal center. But, I was thinking of doing something like JTR does, with slot ports flanking the drivers. You could still make use of the baffle DIYSG supplies with their kit... just incorporate them into a wider cabinet.

I so want to come hear these speakers in person but, unfortunately I will not be able to attend. So I am going to make my decision from the attendees observations. Hoping to get some comparisons between the 1299’s and the Titans.

I plan on bringing my pair of Helix Domes and my Bluesound Powernode 2.

I wonder what these would sound like on the Powernode.

That would be an awesome build. Please post pics.. I would love to try it if I can get the tuning to about 55 to 60 hz with that design. Id rather do Slot ports. I'm definitely going ported, but don't know how low to tune the Center. I just love the look of Ported. With Subs, I'll probably always go with Ported for the efficiency alone.
