It does not move at all, most of the weight is in the lower cabinet which makes it pretty stable.

Can these be inverted and made only 11" deep?

Why only 50hz to drop off! At this size they should go to -10hz.
It was measured indoors (as I can't really get outside to measure this time of year), an average of about a dozen individual on axis measurements between 1-5m, but the slight rise before and sharp drop after 50hz is still the room as it was placed in the middle of the floor in my basement for that measurement. I'd expect extension to be pretty solid down to 40hz or lower in most normal locations.

I don't know exactly where this will be priced but I do know the horn itself is about 16.5" wide.

I love the option for pre assembled crossover on the HTM, are you planning on making that option available on launch for titan as well?

Funny that I almost made this exact setup for my living. Just went with the AP7315 clone for now for outdoors. Look forward in hearing the price and specs.

+1 on this exciting new design, and nice timing - I'm diving down all available rabbit holes re DIY speakers. Also looking forward to pricing & specs. Nice job, guys!

This is my personal opinion on the Titan-615 I was able to hear this speaker because of me stopping by Matt's to pick up some subs and he had these there. I've heard a lot of diysg speakers in my room and like them all and there is a difference between each one offered by diysg. So imo these are my favorite. The sound from the CD the mid and the 15 is just amazing. I listened to these with Matt for about 20-30 mins going through some movies and the bass, mid bass and highs are by far the best I've heard to date from diysg.
Now I haven't heard the 1299's or the 1899's but these sound better than the rest of the speakers I've heard.

I remember moving all around his seats up close, the first row then the second row to see how they sound in each row and it covered each seat perfectly. We had a James Bond moving and there was bass part that played and I asked him if he had his subs playing (4-15's) and he said no with a big smile on his face to give an example. This was with one only on of these playing. So when everyone watches the video on these and watches them move well they move! The cd is so clear playing with mid I really can't wait to get my hands on this kit. He did really good job on the xo I know he tweaked it afterwards a little bit with what was done at the time I heard them was amazing.

Great work Matt!

The Titan doesn't use the QSC horn top section. It looks similar, but it's definitely not the same.

Thumbs up to Eminence for making us 3 different 6.5" sealed back samples. But in the end there just isn't really anything needed to improve on their standard model. After MTG90 tested and listened to them, we decided the regular Alpha 6CBMRA worked great as is. After reading some pro audio forums, I was surprised how many well known companies actually use that midrange.

The upper waveguide needs a screw-on compression driver versus bolt on. I don't have any higher end screw-on drivers yet and didn't want to use an adapter. So after ordering and testing every model I could find, the Celestion 1731 was the winner in sound quality. It has a poly diaphragm and neodymium magnet with a good sound like the compression drivers used in the other kits, which is what we were looking for.

That sealed back driver also has a JBL part number, for a pretty hefty price hike.

Erich, I think you and Matt really nailed this one. The surrounds Matt designed for me are freaking awesome, would have been great to have an all Matt designed system but no way I'm changing mains after all the work I just put into my DIY three-ways.

Hard to describe how good speakers that are horn loaded to less than 500 Hz sound on guitar driven music.

In this situation its a good idea to take nearfield measurements and merge them with the farfield. That will give a more realistic example of the extension. Or even display them independently.

Don't have the space (or WAF) for the Titan but..

The 15" gets my attention. Can they operate at lower frequencies than the 12"? Basically, can a 15" sub be made tuned to 18 or 19Hz and get reasonably flat -6dB performance?

My brain sez no but my heart (and interdreamer) hopes it can. This is what you get for yelling fire in a (home) theater--spill the beans!

I can't get them shipped in boxes from DHL because their size is too big to justify the shipping cost, so they need to ship slower on a pallet.



MKTheater, you could make them 20" wide, but you'd have to make a deeper cabinet.

Is there a way to throw them in the 3 cubic foot sealed cabinet? I have 3 of those lying around.

I really thought a kit was going to come out with the SEOS 18 and BA-750. Does this new speaker sound better than that combo?

This is very exciting! Later this year, I will be moving into a house that will allow me to build a dedicated HT room and I've been trying to figure out what speakers I will plan on using behind a screen. Looking forward to hearing more about these!

MKTheater, Putting the 15" in a smaller sealed enclosure will really kill its low end response, which kind of go against one of the main design points of the speaker. So probably not a great idea, but maybe MTG90 can give a sealed enclosure recommendation.

A SEOS-18 and DNA-750 kit would be pretty expensive because the SEOS-18 would have to be fiberglass. No idea how that project would turn out.



The 15" used in the Titan isn't going to replace normal subwoofers for HT use. If I had Eminence make them with the rubber surround like the Magnum-12, they probably could have. But sensitivity would have been lower and there would be people telling us that the subwoofer shouldn't always be placed under the main speakers anyway. So that idea was scrapped.

Erich is right this 15 isn't going to replace subs but it does have some really nice bass and midbass to it. At least when I heard it. I don't remember what level we played it at but it was loud in the room and Matt only has one of these Titan-615's built.

Nice driver choices. Should be able to come in at a reasonable price. The standard Eminence Kappalite 3015LF is pretty impressive. 9.6mm xmax and 17mm xlim. http://www.parts-express.com/eminenc...river--290-598

This has my interest.

I want to see final specs and pricing, if the cabinet can be built to 20" wide I may be in for three.

Is it the same 84 g mms?

Is there any kind of nice looking outer ring foam replacement for the 15" woofers being worked on? Like the 1099 woofers got.

The talk of the being able to have a woofer built that could be used a sub has me wondering. How hard would it be to get a pro sub driver built with an FS in the low 20s and 95+ sensitivity?

Hmmm... Oh 1099, I hardly knew ya. Jk. Now I've got to figure out where to put my 1099s. I really like them, but I was deciding between the 4722n and the QSC 2150 and just pulled the trigger on the 1099s in the middle of last year. Now I may have to upgrade later this year. Looking good Erich and Matt.

I'd be happy with 92 to 95dB myself--a 15 that will do flat to 20Hz, handle 300 to 600 watts and have 92+ efficiency would be great. (holding coffee mug office space style)
