Official HTM Series Speaker Thread

  1. It will be an MTM, still deciding between dual 8" and dual 10", and between 4ohm nominal or 8 ohm nominal. If you had to pick what would you like to see?
  2. I would like to see a dual 8" with 8 ohm nominal for a horizontal center. Since 3-way SEOS horn centers are available in 1099/1299/1899 or you could pick up a rather tall 88 Special with the 15" SEOS horn--nice to have the option for another dual 8" center with the SEOS horn. Will it be a 2-way or 3-way, will it use the 8" SEOS horn like the HTM-6 and what will the crossover point be? Have no idea the lowest point the 8" SEOS will cross, but if it can cross at 1,300Hz or lower would be great. Another option would be to use the 10" SEOS horn and driver, borrow the 1099 five inch mids and run dual 8" drivers and put the ports under the 8's to make the 3-way HTM center around 30" or less wide when laid horizontally (although still 12.5" H like the 1099). Give it an odd name like HTM 898 Center or something. It would "fit" between the Alchemy 8 MTM center with EOS horn and the larger/heavier 1099 Center. The HTM 898C would have the efficiency, power handling from the dual 8's and punch to give the SPL for the HTM-8/10 and 12. Would the issue be getting 16 ohm versions of the HTM-8 Neo driver?

    Thanks for letting me throw my 2 cents in, I'm purchasing a center kit in the next month or two so have to decide. Any idea when the HTM Ceter will see the light of day? Have a great weekend!
  3. Yeah right now the easiest options are for either a 4 ohm 8" MTM ~98dB/2.83v - 95dB/1w, using two of the 8 ohm woofers from the HTM-8.
    Or a 10" MTM which could be either 4 or 8 ohms (since the 2510 comes in both variants), 98dB/2.83v/1w for the 8 ohm version, 101dB/2.83v - 98dB/1w for a 4 ohm version (just one of those options will be designed).

    It will likely be a two way crossover using a new SEOS waveguide that works better for horizontal MTM designs. Crossover will likely be <1300hz.

    This design is likely a few months out as no real work has been started.
  4. If the 8 has to be 4 ohm, I'd vote for the dual 10 in 8 ohms. Will the dual 10 be 30 inches wide with the horn? I'm aware the HTM series is supposed to be behind a screen but for those of us not using screens, width is always a factor. Just trying to figure out sizes of centers, the new works better for centers horn should be interesting. How wide is that horn since the closer you can space the drivers, the better the MTM. Will it be around 8 inches wide or so? I can see something like an 8" wide SEOS made for MTMs to be integrated into the Alchemy center, that would be interesting. Keep us posted and thanks for the information.
  5. I'd vote for dual 8" strictly for size purposes. The 8" seems perfect for non-large home theaters. I would love to stick a dual 8" MTM underneath my OLED.
