Titan Speaker Kits

Discussion in 'Home Theater Speaker Kit Information' started by Matt Grant, Jan 18, 2017.

  1. Thanks for the info. I might give that a try. If I also get around to measuring them outside again, I'll try gating the response a bit and taking more measurements. Thanks for your help.
     
  2. Well, I ordered the parts. Hopefully I'll get them installed next week. Not sure when outside measurements will be completed.

    hi
    some great information here.
    i have a few questions about room setup:

    what is the recommended minimum room size and distance to front and side walls?
    also , how far to sit from them to integrate properly?

    and lastly : how does the titan compare to the vortex 15 for music, just sonic quality ?

    sorry lots of questions, i will probably do a search on avs also to get some info....

    thanks

  4. Did you have a chance to test out the crossover part revisions for the dual woofer version? I'm finally getting around to building mine and wanted to order the replacement components before I start soldering. Thanks for the extra time you've spent testing these!
     
  5. No I haven't due to a lack of motivation to carry these back upstairs and outside. Especially now that it's cold.

    I will say that now that I have had some time to play with these a while, I'm not sure I would suggest the mod anyways. I have found that with the second woofer added and the crossover of that woofer up to 300 Hz, they still sound a bit bloated until I got them eq'd flat down to 100Hz. Any rise that starts above 100Hz I found undesirable. Specifically noted in deep voices such has Kanan Jarrus from Star Wars Rebels and Chrisjen Avasarala from the Expanse. Their voices just sound boomy and not accurate. Additionally, it was noticeable during orchestral pieces like the imperial march or the Hanz Zimmer performance of Pirates of the Caribbean. The brass didn't feel like it had the presence it should until I got the eq down flat to 100Hz.
     
  6. Totally understand.

    I'm building mine now with the only crossover mods being the omission of the 33-ohm MF R2 resistor, the MF C1 cap increased from 18uf to 22uf and the MF R1 resistor decreased from 6-ohm to 4-ohm (all recommended by Erich/Matt). Once built I'll throw some measurements and feedback up here.

  7. @Matt Grant, I see you edited your first post to include the Titan-818 in the title! Do you have any information you can share about this?

    Eminence 18" woofer,
    Celestion 8" midrange
    Same Celestion compression driver as the 615LX.

    99dB / 2.83v
    8 Ohms.

    350/1700hz crossover points.

    In general just bigger/badder then the 615LX.

    Teaser Pic.

  9. Those look awesome. I'm looking forward to seeing price, footprint, frequency response, and polar plots.

    Will there be a midrange/waveguide upgrade option for people with a 630- basically making an 830?

    Thanks.

  10. Hello Matt. I am having problems deciding which subwoofer you have designed would fit my needs best. I am using a pair of Danley Sound Labs sm60f synergy horns for my tops.

    My listening space is not very big, 12 feet wide by 18 feel long with a listening position of about 12 feet from the front of the room. I want a pair of subs to sit under my Danley's for purely music only listening. I really prefer impactful and clean bass over deep boomy sounding bass. Musical tastes include rock and many types of electronic music. I'm not necessarily looking for pro audio loud, but I really want that felt in my body experience many of the reviewers of your MBM series mention.

    At first I really like the sound of the reviews of the MBM-12, but I think the cabinet would look a bit odd being a good bit smaller than my tops. The MBM-15's on the other hand have a similar width as the sm60f's and the height would be just about perfect.

    Can you comment on the performance of the 15 vs the 12? Do they sound the same with the 15 just having more output? Are the drivers fairly similar in their attributes, as in they excel in the midbass realms? I am also under the impression that the 15 can be tuned to a desired frequency response similar to the 12, is that true?

    Do you feel like the 15 would be a good fit for my tops? They do seem to get really good reviews from people who use them for music, but most of the info on them that I have found has been more from the home theater community.

    Finally, with the addition of the Titan 818 teaser pick above, I might assume that perhaps a "MBM-18lx" or similar may soon be coming available? If this is indeed a potential how would you rate its sound signature in comparison to the mbm12 and 15? Just based on looks, it looks quite similar to the VBSS, of which I am also considering strongly as an option.

    Any thoughts about my questions? Thank you for your contributions to the diy community!
     
  11. Well I haven't directly compared the 12 and 15 in a strictly MBM roll though I do suspect their qualities will be similar with the 15 certainly being capable of more output. The 15 can be tuned lower if needed and I actually would tune it a little lower (~30-35hz) if SQ is a priority over output.

    Now the Titan-818 will be getting a couple cabinet options and those cabinets will also be available as flatpacks for standalone usage with a variety of woofers. The 818 cabinet in the photo is basically a VBSS size cabinet with short ports tuned to ~30hz. The woofer from the 818 may be sold with the cabinet as an MBM/music sub and I feel that woofer/cabinet combo is the most tactile and sounds the most effortless of the three (MBM-12/MBM-15).
     
  12. Thank you Matt for taking a moment to answer my questions, I really appreciate it. Your opinion on the 818 cabinet sounds really exciting, and I think its exactly what I have been looking for. The 30 hz tune with an 18" driver with tactile punch really does check all the boxes for me, especially if you are rating it above the 12-15 which received many great reviews in my research.

    Will the 818 cabinet feature an off the shelf driver? or will this again be something custom tweaked for your purpose? Do you have an idea when these kits/parts are going to be available over at DIYSG?

    Thanks again, very exciting news!
     
  13. I asked Eminence to make us some samples and I think at last count they made about 7-8 different 18" models.

    We tested each one and decided which sample works best in the speaker design and then put in the order. Specs will be posted soon once the kit goes up.

    The design is basically done and all the parts are here, I just need to finish the product page and calculate costs.
     
  14. Thanks Erich and Matt. If I may ask one last question. You mentioned that the 818 cabinet is similar in size and tuning to the VBSS. Could you describe the expected similarities or differences in sound quality, character and output between these two designs?

    Thank you
