HTM Speaker Kits

  1. You should have a piece of paper in one of your kits showing how the crossover is assembled. If you can't find it or misplaced it, send me an email.

    I use my setup for home theater use, but what I do enjoy most is just pure and simple stereo music listening (so 75% music, 25% movies).
    I really do appreciate a good soundstage and imaging, and this would be one of the main things I would be hoping to improve.
    With a good soundstage I do prefer having a phantom center, as I don't have a permeable screen and thus the two speakers seem to work just dandy.

    My room is ~20ft wide and ~10ft deep, and I listen with the speakers ~6ft apart ~6ft away with the front speakers ~3 feet off the front wall to give them room to breath.

    I was thinking that bookshelf speakers would be ideal, as I am using my Marantz SR 7002 for bass management and currency has a crossover set at 140hz as I am using bookshelf speakers and dual subs currently.

    I was looking into the HT vs HTM series and wondering if you think that would be the best fit? Or would you recommend something else? or what within the HT/HTM would you recommend?
  3. I'd go for the HT-12 or HTM-12 if you want the best phantom image from the speakers. They have the largest waveguide witch gives them the most directivity control. Though the smaller HT models will also work well especially at that close distance.

    The HTM-12 will have the edge in sound quality if you are willing to splurge for that model. Otherwise the HT-12 is nearly 90% of the HTM-12 if you are on a budget.
  4. Perfect! Thanks for the reply! Just making sure you think they would also be the best option for music and stereo imaging / soundstage.
    The HTM-12s have slightly higher end components is that correct?
    All these options certainly can lead to analysis paralysis, so looking for one final thumbs up before ordering the HTM-12s.
    Thanks again! I really do appreciate the input!
  5. How does the 88 Special stack up against those two?

    I've just ordered 2 HTM-12s. I am struggling to find the recycled denim insulation in the UK. I've found some sheep wool 100mm insulation for walls and floors. I was wondering if this would be a good substitute for lining the speakers? If so, do you need to stick the insulation to the walls with a spray adhesive? Many thanks.
  7. I can't comment of the sheep wool though I "think" it would be fine based on info I looked up. Also 100mm is too thick, 40mm to 50mm should be fine.

    Yes you need to attach it to the walls somehow. I used spray adhesive in both my HTM12's and HTM6's. The smaller panels of the HTM6's made it easy to get good adhesion. However I had issues with the larger panels on the HTM12. It may have been my brand of adhesive being sub par?
  8. I lined my Vortex-15s with rockwool that I had leftover from building bass traps. I secured it by covering it with Parts Express speaker grill cloth (also left over from the bass traps) and stapled it down. Works well, looks pretty good, and traps the fibers.
  9. I was thinking rockwool, but those fibres scare the heck out of me.
  10. I definitely wouldn't want it loose in the cabinet, but it seems fine covered with with the speaker grill cloth, which is more substantial than I might expect. I've had no issues with my acoustic treatments that are also rockwool covered by the same fabric (although for those I did layer a nylon screen under the fabric so my cats couldn't slash through to the insulation).
  11. Hope everyone's staying safe! Looking to buy a three pack of HT-10s soon. Any ETA on HT-10 and Flat Pack combo inventory?

  12. I'm working through the inventory this week. I get crossover components from Parts Express and they're out of a decent number of the parts for many of the kits, so I'm not sure how many I can put in stock.
    Nick S and Subramanian Arumugam like this.
  13. Erich - are you guys still waiting for drivers for the HT-8s?
  14. I do currently have the HT-8 parts and also ordered more woofers last week. I am finally in the new building and slowly getting kits back up on the site and should get some of the HT-8's up this week.
  15. Ok, hopefully my last question before I put in an order (and when stock becomes available)!
    I have been doing more reading about the importance of the off axis response / polar plots and also resonances and thus I have been beyond impressed with the off axis response / polar plot for the HTM-12.

    I have done some further looking and have managed to find the HT-12 off axis response on an AVS form (have not found the polar plot, but since it comes from the same date, I can easily visualize what it would look like) and it also looks pretty darn goodHT-12 off axis.png .

    What I am wondering is if there are off axis responses / polar plots for the HT-8 and HT-10 (to compare to the previously posted HTM 8 and 10 data). Its ok if the data does not exist, I am just wondering.

    Ideally I would also love to see the off axis responses / polar plot for the updated HTM-12. If that data is available that would be amazing and I think I would have enough info to commit to one (likely the HT-12 vs HTM-12).

    Also, how would the higher end components in the HTM-12 help outside of what can be seen in the frequency responses (sorry for being naive and new to this technical audio stuff)?

    Thanks for any info!
