HTM Speaker Kits

  1. 3" might be too thick for the sides if that is flat but would work for the back of the enclosure, though if it is the wedge or egg crate shape it should be fine.
  2. Yes you can make the cabinet larger for more low end output and extension. A custom enclosure around 2-3cuft tuned to 45hz would be the ideal solution.

    That said you could take the stock baffle and make an enclosure around 15-20" deep and shorten the ports to about 1.5" long which will give you decent extension into the 40's. It's just that the stock ports are a little undersized for a larger enclosure volume and running full range that so they will start to chuff at moderate to high volumes with bass heavy content.

  3. What is the prefered mounting method for the damping material (mineral wool) and the crossover?
    Like do you glue the damping material and screw the crossover?
  4. Thanks Matt, that is really helpful. I'm looking for some wall mounted speakers that shall play in my kitchen / dining room that is about 430Sq ft. I'm looking for someting that could play a bit loud but not reference levels of course and I'm willing to sacrifice some dB to be able to play down to around 45Hz. Can I also make the box more shallow and with higher and wider baffle? 2cuft in size sounds like they wifey would accept :)
  5. If you cut the damping material just right it should be able to wedge in there without any kind of glue to hold it in place. Otherwise you can use hot glue or spray adhesive.

    The crossover should be screwed onto the cabinet wall.

  6. You could make it wider, taller and more shallow. I would mock it up with cardboard or something beforehand to better visualize it in your space, 2cuft is pretty large a box to hang on the wall. In your situation I'd also consider the Apollo or Helix kits which would give very good extension in a much smaller cabinet and should still reach the output levels you desire.
  7. Hi Matt, for mains and a center I was looking at 2 HTM-10s (wall mounted) and the Fusion 8 Alchemy Center. This would be for a large open vaulted room. HTM-12s would be a touch too big. Noted what you said above and looked at Helix and Apollo kits. Would 3 of either these kits be a better choice for sound quality as an alternative? My primary concern is wall mounting a rear ported speaker which would happen with Helix and Apollo but not HTM-10.
  8. I cant seem to find any specs on the Seos-77 waveguide anywhere. In the new HTM 10 center specs it says less horizontal dispersion than the HTM 12. Any thought on what kind of dispersion it has compared to the one in the HTM 12?
  9. I'll get information posted about the new waveguides as soon as I can. I had them made up about 1.5 years ago, possibly longer, just no time to get them in a speaker design.
  10. I'm wondering if it's possible that we'll see an 8" or even 6" version of the center channel. An 11.5" high cabinet exceeds my clearance by 1.5".
