Hey Matt, would there be a sound difference when mixing original birch and MDF low frequency boxes? I'm really trying to figure our how to fit these Titans as surrounds. I have 3 LCR and would really like all 7 or better yet Atmos to be the same speaker. Not easy to find baltic birch sheets. The original 21" depth will have me down to two chairs instead of 3 for a row. My goal is to run the same speaker at full range for the base layer.
Hi @Matt Grant. Steve Smith at Home Theater Gurus is designing my room. He's asked me if the waveguide on the Titan can be toed-in. Can that be done independently from the rest of the enclosure? He's trying to figure out if the whole cabinet needs to be turned so he knows how much to allow for the wall in the front of the room.
Hey Matt, I have a fairly early set of 3 Titan 615 standard version speakers... I love these speakers so thank you for the work you anf Erik have done on these. I have 2 or 3 questions that maybe you can help with. 1) I have one 15 inch driver that was damaged in a move and I would be interested to know if there is a replacement availible. 2) What revisions were made to the cross-over and how do they affect the performance of the speaker? I am currenlty in the process of building new enclosures for these, I figured I'd check on if any updates available would be worth investing in. 3) Lastly, Since I bought the standerd versions I have the lesser performing of the 2 availible 15" drivers. Is it possible to upgrade to the better driver and if so, are they still availible? Thakn you
Awesome! I have the "standard" verson of the Titan with the lesser awesome of the two woofers that were offered... Which do you have availible? I'll likely send email and ask the same! thank you

Erich, do you still have the 21" cabinets and are you planning on putting them on the site? Any chance of getting a price and specs (size, tuning, etc)? Mickey
My chairs sit pretty low so ear height is around 36" depending on if chair is reclined or upright, on the titan 615 it puts the tweeter kind of high. I flipped the upper section over with the tweeter on bottom and that puts the tweeter a little low so I temporarily spaced the upper section up a couple inches to listen and see. It's a subtle difference but the tweeter being closer to on axis vertically does add some high frequency response that is nice. These have the newer crossovers with the mods already incorporated. Interested in thoughts in general with the mid on top, and I think I'll make some bases that raise the whole speaker a couple of inches and run them flipped. I guess it's better looking to put the spacer under the woofer section and raise the whole cabinet than to raise just the upper section. I've had the crossovers sitting in the back of the upper section but they don't fit there with the tweeter on bottom so I think I'll mount the crossovers in the woofer cabinet as well and use a speakon four pole to feed the uppers.
Hey Erich, that’s how I’ve had it but probably not enough tilt. I’ve noticed that on my mini statements with TM arrangement it tends to sound better above the tweeter, but that doesn't seem to apply to the titans the same way, probably due to more controlled directivity. I might try the more tilt and see, just don't want the upper sections to vibrate off, things move around in here if they aren't nailed down. I've thought about coming up with a screw type arrangement to fix the upper section to the cabinet and have the back able to be adjusted, just haven't figured out what to do that would require minimal mods to the cabinets. Maybe magnets in front and an adjustable foot or feet in back.
More tilt is good, it's a better solution I think because if I can ever get to building the 818s that will go in this room they will need the tilt as well, and flipping the top section is dependent on the height of the woofer cabinet, but tilt is not. Now just need a simple way to attach upper section, rubber feet are moving around and just not great. Magnets and adjustable feet I think, if anyone has a better solution post it up.
If you want adjustable tilt I'd use a pair of 90 degree brackets at the front of the cabinet, screwed down to the cabinet with a bolt on each side into the waveguide bracket. Something that looks a bit like this: Then use a single adjustable L-Bracket at the center back which would allow you to adjust the angle (may require some minor bending):
@Matt Grant thanks, that black bracket could work at the back and be adjustable. Maybe some of the magnets with screw holes at the front, they could be hidden. I tilted them down and it was noticeably brighter, the Dirac had probably boosted the highs. It was interesting and not subtle. Got around to re-running Dirac and it helped with that. It's an incremental improvement but worth the effort for sure.
Hey @Matt Grant I just bought three of the titan 818s. Very excited to get the flat packs to build these. I see that 2 inch acoustic foam or denim insulation is recommended with the titan 818 flat pack. I'm having a hard time finding 2 inch foam and I have spare rockwool safe n sound insulation left over from building some acoustic panels. Can I use the rockwool with some spray adhesive to line the inner panels or is that not recommended? Would it be better to use 1 inch sonic barrier foam from parts express?
