The Twins - DIYSG Titan-615LX Build
 
Imgur Album



So a little backstory, I’ve been meaning to build some end-game mains and have been eyeing multiple DIYSG designs for years. It all started when I heard a pair of 1099’s at the 3rd Annual Upper Midwest GTG July 2015 at @lukeamdman house.

The value was obvious, the sound was phenomenal, and I had to hop on the DIYSG train. Throughout the years I read threads ranging from the Fusions to the Volts to the 99 series. I knew I wanted something with high sensitivity but with a little more authority down low. This led me to the 1299’s. @bossdog304 in southern Minnesota was so kind to allow me to demo his setup and I was floored. He had a huge space and his 3 1299 setup filled it up amazingly. The highs and mids were truly incredible, but I felt the need to add a bit more authority to the lows. Off to WINISD I went for the next few weeks to model up some ported 1299’s that would go a bit lower. In order to maintain a smooth frequency curve I ended up with a 10cu/ft box tuned to 49hz measuring 66” x 21” x 16.25” that would likely weigh 200lbs built with MDF.

I was about to pull the trigger but I was compelled to do a run-down of all of DIYSG offerings one last time. This led me to the Titan 615LX. Countless hours of diving into build threads and listening reviews formulated the conclusion in my head that these would not only sound better in the highs, but have a serious amount of authority even down into the 35 Hz range, all in a much more manageable package. The ability to buy a flat pack allowed me to assemble these beasts in my basement in the freezing Minnesota winter without having to pull out the table saw. I caved in and made the purchase in February 2018.

The baltich birch was flawless and easy to work with. I used gorilla glue and clamps from Lowes.

Used 3M 77 spray adhesive to glue in some excess foam mattress topper I had lying around to line the inside of the cabinet.

Finally onto the baffles.

I’ve been in love with black duratex ever since I built a few Full Marty subwoofer cabs so it was a no brainer to take this route again.

I opted to mount the crossover board to the bracket because it’s far too pretty to hide. I also screwed in some rectangular binding posts to the corner of the bracket which worked out perfectly.

Done!

The first time I fired these babies up I knew I had made the right decision. I had to confirm not once, not twice, but three times that my subwoofer amplifiers were indeed OFF. That’s right. The bass out of these babies is drywall flexing, rib cage reverberating, and organ palpitating. And the woofers are barely even moving with the 100 watts I’m feeding them.



The stereo imaging took me by surprise. At the end of Pink Floyd - Another Brick in the Wall where the man starts yelling about “How can ya have any puddin’ if ya don’t eat yer meat?!?!?!”, his voice was clearly coming from 3 totally different corners of the room and it freaked me out.



The bass kick from these is downright violent and unexpected considering the size of the cabinets. Talking Heads – Burning Down the House comes to mind as a great chest thumping track on these speakers that really blew me away.


The highs are absolutely one of the crispest I have ever heard. Bird sounds, ocean waves, high-hats, all sound incredibly real and life-like. For audio with a lot going on, instruments are separated and easily distinguishable no matter how complex the track is.



Overall I am floored by the Titan 615LX. It’s an explosive speaker, in a relatively small and lightweight package, for a VERY reasonable price. I don’t believe the value could ever be beat for what you get here. It has hit all my marks and then some. If anyone is on the fence about these I’d say don’t be. Life is short. Whip out the credit and improve your happiness 10 fold.

the imaging of bigger horns is really nice. i think the next "better? you could do would be a danley soundlabs sh50 which is a lot more expensive but offers a significantly bigger horn and therefore lower horn loaded extension. For the typical home theater however, the titan is a great choice for the size/price.

The ideal atmos setup to me is 5 of the titans across the soundstage but "matching" in horns is not as big of a deal to me as it is in traditional dome tweeter surface loaded speakers where timbre matching seems much more of an issue.

With horns, the lower that a horn goes in FR, the nicer that I find that speakers sound.

The Titans look great! Another happy customer [emoji51]

VicTorious1 05-19-2018 06:02 PM

Looking good. Do you have the Titans paired with the two Fully Martys and two dual sealed subs? If so, pics?

Jk7.2 05-19-2018 06:40 PM

Nice build! Any plans to add a center channel?

Gonna rock a phantom center until I move into my new place next year, then maybe consider a center at that point.

Off topic but, how do you post pics like this ? I have Imgur, but I can only figure out how to post a link to pictures, not the actual pictures themselves.

Right click the image in your imgur album, copy image location. Then use the "Insert Image" option on AVS and paste that link in there.

tk123 05-20-2018 10:17 AM

I normally use my phone for taking pics and posting. Is there a way do do it from phone ?

Place the link inside [img.]....[/img.]

You need to delete the two . After img

For posting from phone choose advanced then manage attachments, select photos on phone, click upload, once done close that and post.

Well that didn’t work like I wanted it to.

Click as if you're going to quote my post, and see what I changed on yours to make the pictures show up. Each instance of "url" or "/url" becomes "img" or "/img"


jjackkrash 05-20-2018 11:45 AM

Are all the parts in your build from the kit except the the spring loaded circular terminal cups?

Also, and maybe a more general question, I notice everybody uses clamps, is there a reason not to use 2P10 and skip the clamps? (If you have never used this, you hold for 10 seconds and its cured in 30 seconds and its crazy strong).

In addition to the 615lx kit, he's ordered the waveguide supports, assembled crossover option and the plywood flat packs for the 15" woofers, and the rectangular binding posts. The kit comes with the front baffle if you are building your own enclosures.

Steve Kuester 05-21-2018 11:44 AM

Nice. You're going to be a stop on the next tour, right? I would really like to hear these.

I don't have a dedicated space yet, but I spoke with Luke and he was very willing to let me demo these at his place at our next GTG!

Even better. I'd love to hear these next to Luke's mains.

@kaiforce - Looks great I just got the kit in and am gathering the rest of the supplies needed. Looks Awesome BTW!


I am going the duratex route for paint and curious as to how much you used? I was thinking a gallon will work but not sure any input would be appreciated. Thanks

Paint it on with a foam brush to start you off with a dark slate and you can get away with 1 thick coat. These boxes don't need much. A gallon is plenty.

These look great, and I really like your decision to mount the crossovers visibly. I had a thought while I was looking at your pics... these would look PHENOMENAL with a custom black PCB used for the crossover board. If I ever do a set of Titans that's what I'm gonna do (now that you put the idea in my head). :)


Also, way to fully exploit the width of your room!
