  1. Drywall's hung and taped.  Finishing will start today.

     

    Test fit all the holes for lights and speakers.  Kudos to Klipsch for designing the CDT-5800-CII with 1 3/4" reach on the retainers. So they will easily be mounted in a ceiling with double drywall thickness.

     

    Side surround backer boxes fit well also.  Looking forward to mounting speakers, but have to build stage, riser and columns before paint.  Then speakers!

     

    Happy New Year!

  2. It's been awhile since posting, but I'm getting closer.  First layer of drywall has been installed except for the bulkhead area where we have to move drywall to have access.  Second layer installed on the ceiling and in the areas where false soffits needed to be built.  Those were structured today and the speaker wires have been routed to the equipment rack area.  Hoping to be ready for mud and tape this weekend!

  3. Clips and channel installed for the ceiling.  Backer boxes installed and wired.  All cables run.  Ready for drywall.  

     

    86 sheets delivered.  Will start hanging it this week.  Partnering with a friend that does drywall finishing to do the whole job, including paint when the drywall is done.

  4. I've seen recommendations on other forums to either loosely stuff the boxes with poly-filll or to simply put a square of insulation in one end of the boxes. So I'll probably do the poly-fill.  I've not encountered any suggested downsides to either approach.  Any comments here?

  5. Should I put any insulation inside the boxes around the speakers?  Or leave them bare like the Heresy speakers are?  I've had one recommendation to put a square of insulation in one end of the box for damping, but am hoping for more suggestions.

     

    Thanks!

  6. Backer boxes finished. Good first experience with applying Green Glue. Toughest part was cutting and fitting the drywall in the boxes.

    Ultrathin recessed light fixture boxes:

    Combo boxes. These will accommodate both a speaker and a recessed light placed next to each other in one box .

    The sealant isn't pretty, but won't be visible. I plan to use the approach of mounting them with supports fastened to the ceiling channels. After doing the small replumbing job, I'll install DD + GG under the two HVAC supply runs and be ready to locate the backer boxes and finish the ceiling insulation. Then on to building one last bulkhead before running speaker wiring. I also need to run a LAN cable from my upstairs modem to the theater. What do you recommend? CAT 5, 6, 7, 8? I'm totally unfamiliar with network cabling and will appreciate your advice. It will be about a 50' run.

    Thanks for the suggestion.  I've looked at those and wouldn't mind using them, except they are pretty pricey.  I'd rather build something at much lower cost and spend that money on other areas of the theater build.  The Dynabox looks like the bees knees for retrofitting though!

  8. I'm going to start building backer boxes soon, so thought I would ping this group on size and interior treatment.  The boxes for the CDT-5800-CII's will be about 12" wide x 12" deep.  The length can be pretty much anything within reason.  Any recommendations on approximate volume of these boxes?  They'll be made from 5/8" MDF (because I have it) and will be lined with a layer of either 1/2" or 5/8" drywall for soundproofing.  So, I'm trying to decide how long to build the boxes and if they should be stuffed with some absorbent material.  If I make the boxes 1.0 - 1.5 cubic feet of volume, should that suffice?  Would I gain anything by increasing the volume?  I suspect not, since I doubt there will be much low frequency sound coming from above.  And should I stuff them with fiberglas insulation or pillow fluffy stuff or something else?  Or leave them "unstuffed"?

     

    Thanks for any advice you can share!

  9. Thanks.  I'm engaged and totally looking forward to the journey. 

     

    Funny story...I received the six CDT-5800-C II's yesterday and had them temporarily stacked near the kitchen.  My 90-year old mother in law looked at the boxes, and focused on the word "ceiling".  She asked if the boxes contained ceiling tiles.  And I said no, they are speakers.  She said speakers, why do you need so many speakers?  I replied, because I only have 13 and need more!

     

    Cheers!

  10. Oh no, Bill, I'm in the early stages of theater construction.  I expect it will sound fantastic, but will have to wait awhile to confirm.  I'm working on two projects at the moment, so the HT won't get my full attention for awhile.  I've been collecting the audio gear for quite awhile and actually have spare amplifiers to press into service if needed.

     

    Attached is the current status of what's not in boxes.  All of the speakers could certainly use refinishing, but since they'll be hidden in the theater, that's not part of my plan.  I fire them up to provide incentive as I work!  And yes, it does sound good...

     

    Cheers!

  11. Thanks for all the responses.  I bought the CDT-5800-C II's today.  There was no recommendation for enclosure size.  These speakers were meant to be installed in the infinite baffle of ceiling joints, so no enclosure is required or specified.  

     

    Looking forward to getting them to the point that I can fire them up!

     

    Cheers!

  12. Thanks for the warm welcome and information.  One other question related to the ceiling speakers.  Since this will be a soundproofed room, I'll be installing the ceiling speakers in backer boxes.  I've looked at the Klipsch specs for the 5800's but there is no info on recommended volume for an enclosure.  Any experience to share?  I'll ask Cory as well.

     

    Thanks,

  13. I'm in the process of (finally) building my home theater.  9.4.6 configuration using all Klipsch Heritage speakers for the bed channels.  3 LaScala I LCR and 6 Heresy I surrounds.  I'm about to order 6 speakers for the ceiling.  Since there are no Heritage speakers built for ceiling installation, I'm leaning toward the CDT-5800 C II.  Can you share any experience with this combination in timber matching and seamlessness of sound for HT use?  I'm about ready to give Corey a call, but thought I'd check in here first.

     

    Cheers!

  14. How about mounting a pair of HI's, or HII's "Chipotle style" in the ceiling between the studs.

    Bill

    That's a great idea, Bill, and one that I had thought of. Problem is a Heresy is both to wide and too deep to fit in my ceiling joists. I'm wondering, though, whether in-wall speakers would be just a good or better than the in-ceilings. They would certainly fit into the joists. Might they have better range?

    Cheers!

  15. QUOTE=SoundChex;25707745]Actually, it looks to me that installing a Front Height Left|Right (FHL|FHR) speaker pair plus a Rear Height Left|Right (RHL|RHR) speaker pair and configuring the AVR to use them as the Height1 and Height2 speaker pairs in an Atmos 5.1.4 configuration would also produce a speaker layout correctly structured for Auro-3D 9.1. (Looking at the user manual for the Yamaha RX-A2040|RX-A3040, that seems to be the only Atmos speaker configuration offered...?!)

    Thanks Sancho. This is the first diagram I've seen with the recommended angles for the ceiling speakers. I guess I have time to wait on the Dolby official recommendations. And I thought I could just do 4 ceiling speakers, but these diagrams indicate a whole lot more! Perhaps for the true Atmos "cinema experience", but I'm thinking 4 will be enough for me.

    Cheers!

    Chuck

  16. I emailed Klipsch tech support with this question, but haven't received a response yet. When I do, I'll post it here.

    Sancho, where did you find the Atmos speaker diagrams? I've done some preliminary searches, but it seems Dolby must be waiting for their Atmos introduction later this year before they post that info.

    Cheers!

  17. The kpt-1201 has the same 12" as the heresy. But idk how I would feel having them right above me. If they fell that would be pretty bad.

    I think I agree. Looks like it would be almost like mounting Heresys in the ceiling. I was thinking more about the Architectural Series speakers that are designed for in-ceiling mount. Perhaps I should run the wires and watch for new Klipsch Atmos-inspired speakers to emerge......

    Cheers!

    Chuck

  18. As I understand Atmos, the desired location is in the ceiling for all 4 speakers. So that's what I'm researching. I'll run the wires for sure. Just looked at the Klipsch Architectural series. Products are available in a variety of sizes in the Reference and THX Ultra II lines. Just hoping to confirm how to best timbre match.......

    Thanks,

    Chuck

  19. I 'm in the process of building a dedicated HT in my basement. I've purchased most of the electronics and the speakers. It will be a 7.2 system including La Scala LCRs and Heresy surrounds. With the pending introduction of Dolby Atmos, I plan to wire for four ceiling mounted speakers, in the event I decide to include Atmos at some point. That leads to the topic of this thread. What Klipsch ceiling mounted speakers would best timbre match with the Heritage line? I'm looking to check for fit and cost in the event I decide to include them.

    Thanks for your advice!

    Cheers!

  20. I'm using an XPA5 to power my 3 LaScalas and 2 Heresies. In someone elses system the noise floor may have presented itself, but it has never in mine. My system is dead quiet. I wouldn't hesitate to recommend the Emotiva.

    Whether or not the power is necessary, I did it for the same reason mentioned earlier. It was worth the money to exterminate the upgrade bug! And trust me, this setup will kill it! However, I don't doubt that the lesser amp would have been fine.

    You're going to have one fine system. I had to go with RS62's for my sides due to space constraints, but they do a great job too.

    What do you have in mind for subs? edit: oh, I see the pair of Tubas in your sig. What's your room size?

    The room will be about 3500 cubic feet in size.

  21. Thanks again guys. Based on the comments about low noise floor and Emo's questionable ability to satisfy in that area, I'm now looking at some Class D amps, even a DIY version. The reviews on these are that they have a virtually undetectable noise floor and that they have a warm, tube-like SQ. And Class D amps are great for subwoofers too.

    Still pondering......
