Sealed LCR 1299 Build + Questions

Hi,
I am about to go to HD and begin my new 1299 LCR build (+2 recently done VBSS).

Question- Since it is sealed, per diysg website I should use polyfill. How much polyfill should I use per speaker/total (how much should I go buy?). I noticed walmart has 5 and 10 pound boxes, HD has denim insulation etc. I would love so input/recommendations.
I am also unsure of where/how much to put it. There isn't much info on the page there.

Cheers

Just pack them nicely from top to bottom. Since these are sealed and the backs of the mids are sealed, there's nothing to worry about. The old rule for subs was ~1 pound of poly per cubic foot of cabinet.

Quick build update:

Started building the 3 boxes. Bought a circular saw for the cuts, and used jigsaw for the bracing (bracing not yet glued in).
I am concerned about the proper bracing method for the center, any comments on if this was sufficient would be appreciated.

Cheers its looking like an actual speaker box now

That looks correct as long as the half braces are in the middle of the 12 in. drivers.

Nice job and the paint job makes the speakers really stick out.

Nice. A few friendly recommendations:

- I build little box stands for my sealed 1299s to raise them up a bit and bring the waveguide to ear level. Might want to think about that. See attached pic.

- you need to pull them out from the wall a bit and toe them in. This will really help the sweet spot.

- I hope you plan on getting some absorbtion into that room. With the tile floors......your going to have a lot of reverb and echo issues.

Otherwise, nice work.

Are you running the THT's as your subs with the 1299's? If so what are you crossing at?


Sorry OP for off topic.

Yes. I'm running 4 xover at 80hz. I have a 7300cuft sealed room I'm using as my HT.

Nothing wrong with having a set of 1099's and 1299's.

I'm sure 1099's would make great surrounds!

Have you ever compared the 1299's to the 1099's as far as sound quality and impact?

I've listened to both. Not back to back it even in the same room. The 1099 is what pushed into DIY. To me, the 1299 has a bigger sound. Which, shouldn't be surprising. But, the 1099s are truly amazing speakers.

My lord, if this is your intended room for these with the subs then you either live alone or have the most understand wife imaginable.

Really nice job you did on them.

@WickedDogs and @Rowan611

Did you use different crossovers for the vertical left and right vs the horizontal center channel?

I have 3 vertical 1299's but want to change the center to a horizontal orientation. I'll be ordering a new baffle but didnt know if I need a new crossover as well.

As far as I know it's the same. But, @mtg90 built mine. So, I cant say for 100% certainty.

Great point, @mtg90 built mine too, I should've thought to PM him. Thanks for the reminder

You can build them that way depending on the driver depth.

They are designed for a certain box volume.You can adjust the size a little bit without sacrificing much.Cutting the box down to less than half the size would not be good.

Just my .02

according to spec, the 12" woofer's depth is 5.35" only, would it ok to have 6" depth enclosure with minimum space behind the woofer? what's the required height if the depth=6" and width=13.25" in order to remain the designed box volume?

Wow I’m impressed . I have a plethora of wood tools,and sometimes kick myself for not building my own speakers .
I still haven’t heard any remarks regarding how they sound ? Although you may be biased lol .

I’ve never seen these before . Is this a kit you buy ,and just build the enclosure to the recommended volume?

Thanks ,that’s very interesting. Are you owner builders happy with the sound of the waveguide tweeters?
I’m debating to buy a 5x5 wood cnc router next summer ,and would be able to make front baffles very easily .

Are you guys sealing the midranges off inside the enclosure? I guess I’m asking if you’ve made a separate enclosure internally,in order to isolate the drivers from the main woofers
