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.
(Picture shows a mockup of ported 1299’s with Full Marty 18” subs on the side and dual sealed 18” subwoofers in the center)
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.
(Pre-assembled crossover boards were flawless)
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.
Drilling holes to mount the spring loaded circular terminal cups
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.
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.
