1299 Speaker Layout

More info on parts used will come later. I wanted to see which layout you guys think is best for the 1299. I need to decide if these will be ported or sealed because I'm only going to be able to get one flat pack made up for this design. I could get extra baffles cut for any of the options though.

Sealed will get down to 80hz with some pretty good midbass. Measurements would be about 15"w x 40"h x 13"d.

Ported would obviously give more midbass, but would be bigger and cost a bit more due to a larger enclosure and cost of ports. Measurements would be about 15"w x 44"h x 14"d.


I've also drawn out slot ports or round ports. Which of those do you like best? I like the slot ports, but the only ones I could find are the ones used in the Fusion-15 and those aren't the prettiest ports, but functional.

I'm leaning towards sealed for the flat packs just to keep size under control. Any ideas?

I vote for sealed. It would not take up much more space than the 1099 currently does.

For an additional 4" in height, definitely ported

Just to add, IMO the allure to these "12"99's is the improved mid-bass they'll offer. Let's not neuter that.
If space is a concern, there are many smaller product alternatives. Another option is to offer both baffle types for sealed & ported.

Argh -- I just completed my 1099s! I may have to make those into bedroom speakers to upgrade to the 1299s!

If porting allows for more midbass, then doing that will allow these speakers to stand out in your line up. The sealed version isn't much larger than the 1099, it would be crossed over at 80Hz and it would have the same sensitivity. Not much differentiation and frankly probably not with your effort. For more pronounced midbass, right now the only options in your line up are the quad woofer 893 (untested with lower sensitivity) or the 1899. I love the idea of the 1899 but the cost and size make them not very realistic for most people. 15 x 14 x 44 is big but doable.

Would porting these allow them to be crossed over to a sub at 60Hz? If not would going slightly taller allow for a lower tune so one can easily and safely cross them over at 60Hz? Allowing for more midbass and a lower crossover point would distinguish these from the rest of your pack and probably allow you to reach a larger demographic.

BTW I prefer the slot port 😁

Are you planning a horizontal center channel, too?

Yes, there is a center channel just like the other models.

This design is pretty much done, I'm just curious about sealed versus ported. More info will be posted later.

From what I've read, anyone that doesn't have enough midbass from the ported 1099 needs to adjust their speakers a little better because six 10" pro woofers should allow for plenty of midbass.

Ported using slot ports is my vote. I really, really like the look of this...the next question is obviously going to be "when can we have them?"

Easily cross at 60. Even sealed that would be doable.

For the L&R I want which ever gets me the best for my ear listening height of 35". Ported or sealed will require a sub anyway. If ported--I'd prefer slots.

Which drivers are being used? I probably missed a link somewhere listing the drivers.

I also agree with slotted ports. But then again the sealed would save some real estate probably at the cost of spl. If you get to that point though, you are in for some ear troubles...me thinks...

The height of the waveguide center is about 23.5" for sealed. Ported is about 25.5", so probably not enough difference to matter.

Would these be offer along with a flat pack or just a baffle?
Thinking I might like to try these and then sell Patzig my 1099's for over head ATMOS speakers to blend with his 1899's .

Once I figure out which design to go with I'll get flat packs made up. But I can get just the baffles made for which ever option isn't turned into a flat pack.

Sealed at 40" tall I think the entire cabinet can be cut from a single sheet of Baltic birch.

My vote is sealed if you can add several inches to the bottom of the flatpack to result in a free standing tower that doesn't really need stands. With the drivers power handling and sensitivity then some EQ, I think they should suffice with mid bass. Based on the tuning of the 1099s, the 1299s would be tuned lower, but if I'm crossing my subs over at 80hz, would I benefit from the ports? Sealed would sure keep cost down and offer more flexibility.
But as far as bang for buck, sealed has my vote for sure.

Designing a simplistic base for the speaker (at least the L/R) would be a first also wouldn't it? That would be a cool option I suppose.

I'd like to see sealed with an overall height of 48". If they could still be strong to 60hz this would negate the need for additional mbm's.

Sealed probably won't be "strong" at 60hz without some EQ. There aren't many pro audio woofers that will do that in sealed enclosures.

To get the center of the waveguide up to 40", the enclosure would have to be over 50" tall. That would be pretty much impossible to ship as a flat pack, or baffles that could be snapped in half.

Ideally they would sit up on some type of stand. Those could be made for very cheap, I'm just not sure what size people would want because it would likely vary a lot.

Really how many guys "here" don't have fairly indepth eq skills ?

How about offering a baffle that put the wave guide on top with the mids and the two woofers underneath ? I'm looking to get the waveguide to about 34". With this option going ported would work fine. Have one large ported chamber and a small sealed chamber up top.

Stands are quite simple but an actual tower is quite desirable.

Erich, do you think it would be easier to EQ out midbass that is stonger than ones preference or add it via EQ? My understanding is most auto EQs in AVRs decrease peaks to make the response flat but add very little and typically only try to minimize dips, not add midbass. And very few auto EQs allow for a user defined target curve. I may be wrong but boosting via EQ would seem to necessitate an additional EQ put into the mix for most people. Dirac Live is probably the ideal solution but it is of course really expensive.

If you aren't able to personally EQ your speakers other than running an auto EQ, look at this from another angle:
Cutting down dB levels from the midrange/bass will save a little juice from your amps as apposed to needing more

Auto EQs are still going to let the drivers be drivers. If I have an SVS PB-1000, and I run my auto EQ...I get my "flat response". Now lets say I have an SVS PB-2000 and I run my auto EQ...wouldn't their be more bass with the PB-2000? Auto EQs just basically correct for room modes and set speaker/sub distances to make sure everything is playing on the same page.

I get that . So basically what you're saying is auto EQ let's a speaker designed to have strong midbass continue to have strong midbass but it will not add it to one that doesn't inherently have it. Of course that's where external EQ comes in. I personally am looking for strong midbass preferably without the need for external EQ.

My vote is ported. Erich would corner ports be an option to keep overall height down? or maybe even rear porting?
