Hello all,
I would like to introduce myself, my name is James, but I go by JJ. As you can see I am located about 30 miles east of St. Louis on the Illinois side. We just purchased this house last year and finally have the room to build the home theater. I am very excited

to build this room and will be a dream come true for me when it is done. This is a room that I have been wanting to build for about 15 years now. I am planning on doing all the work (no use of contractors) with some help from family and a few friends and of course the knowledge base here on the forum.

I have been checking out the forums here and seeing everyones progress and admiring there work and wanted to officially start my thread for my HT build. Looking through the gallery of the HT's, I am really impressed with the workmanship of a lot of these rooms. I am hoping that my room will turn out half as good as theirs. I hope to gain a lot of knowledge from forum members here while building the room. I would like to thank everyone who has posted there experiences on the other thread titled "Things I wished I would have done differently on my project". I would like to especially thank Parker Clack for starting that thread. There is a lot of good information and insight in there that I plan on implementing.

Now that my wife is happy with the scrapbooking room I built for her in the basement I can now turn my full attention over to the HT room.

I am on a limited budget (trying to stay around $5K to $6K) and will try and get the most bang for the buck setup. I welcome any suggestions that people may have for me while I am building this room. I have a lot of ideas for the room and I am making many of the pieces of the room myself. Please let me know if I am planning something that may not be a good idea.

First, I will start off with my diagram that is not totally to scale of what I have in mind for my theater room. If you see any flaws in my design or misplacement of something or something I should add, please feel free to comment on it.

Here is the list of equipment that I have purchased so far:
Panasonic PT-AX100U
Elite ezScreen 120" High Contrast Grey
Toshiba HD-A2 HD DVD player
Onkyo TX-SR805
Klipsch RC-62 Center Channel
Klipsch RF-82 Fronts
Klipsch RS-52 Surrounds
2 - 15" Exodus Audio Tempest Subs (Infinite Baffle Setup)
Behringer Amp EP-2500
Behringer Parametric EQ
Monster Power conditioner and surge protector HTS-3600
Buttkicker Amp and 4 Transducers
Insteon Lighting system and software
Harmony 1000 w/ RF extender

I am planning on purchasing an Oppo DVD player and maybe an HD player at some point. I will also be looking into getting a new satellite reciever for HD content. I am also working on building an HTPC to play movies, music, and pictures.

Here are a few additional pictures of the current state of the room.

I just received my speaker wire from Bluejeanscable and hope to start running speaker wire this weekend. I also plan to get started on the platform for the second row seating.

Here are some photo's of my A/V rack that I am currently working on. I planned on painting the interior of the rack flat or satin black. The arrows are pointing to a slider that I made for a glass door. This will allow me to keep the tinted window closed or I can swing it open and slide it along the outside of the cabinet for storage to keep the rack open or to keep the kids from accidentally breaking it.

I will post some current pictures of the A/V rack along with the DVD storage pull out that I have also made. The DVD rack will hold approximately 300 movies or so. The slideout will have a handle located in the middle of the door and will pull out of the wall and has storage on both sides of the rack.

I am looking forward to get to know everyone here and getting some advice and answers to questions that will arise during the build. I welcome any thoughts on my whole project, especially if you see me heading for a pitfall. I would like to Thank everyone in advance for any future feedback to any of my questions and or responses. I will try and keep my build updated on a regular basis to let you how I am progressing.

Thanks,
JJ

Hello Jim (JJ),

Welcome to the forum!

Hope your HT construction works great. There's one thing I immediately noticed, because I'm having a giant (

) reconstruction going on myself: the chairs are in the room where you're still working (drywall and all). Isn't that extremely dirty? Or did you just put them there for the photos?

Cees

JJMJ71 · 06-10-2007, 09:02 PM

Thanks Cees, I hope your build is going well also.

I received my projector and screen and wanted to see how everything is going to work together. Basically wanted to do a mock up of the room make sure there was enough space between couches and stuff like that. Now that I have that done I will recover the furniture up with plastic drop cloths.

Did you have pictures up of your room up on the forum yet?

Thanks,
JJ

Cees Alons · 06-11-2007, 05:54 AM

Yes, I figured it must have been something like that.

No, I don't have any pictures up yet. I'll need some time to sit down and prepare it. (Also, reconstruction-English (-jargon)

is more difficult for me to produce and it takes even more time.)

Time for an update...

Well I made some good progress on my platform for the second row of the HT room. I still have to finish the steps and the wall enclosures around the back couches and the wall along the back of the front couch. I am also in the process of running wiring for buttkickers and electrical wiring for lights around the steps. I also have insulation that I will be putting inside of the platform as soon as all the wiring is complete.

I also have an update on my speaker delema...
I had a business trip to Washington DC and while I was up there I thought I would go around and check out some of the Home Theater stores in the area. I have been looking at getting the Klipsch RF-82's (fronts) and the RS-52's (Surrounds) and at the moment I am planning to run 5.1 surround, but will pre-wire the room for 7.1 for future use. The cheapest I have found these four speakers for is around $1200 - $1300. I went into a place and they just happen to be having a sale on Klipsch speakers. I was able to purchase all four speakers for $1000 and a $100 for shipping. Needless to say, I was pretty happy with deal. The speakers should be arriving sometime this week from the store.

For my AVR, I will be purchasing the Onkyo TX-SR805. I have been reading many good reviews about the receiver and I am looking forward to purchasing it and hooking it up to the Klipsch speakers.

Here a are a few pictures of my platform in progress.

Another angle...

I will post some pictures of the platform when I get some more done.
Any questions or comments are welcomed!

JJ

Finally another update of progress.

I have the platform constructed and is awaiting wiring for electrical and speaker wire for the Buttkickers. I will then have the construction of the platform complete. Here are a few pics of the platform with the walls and steps all in place.

Almost done with platform

The constructed platform

I also have been busy constructing the stage and have completed it, minus the walls that need to surround the screen and the side walls that butt up to the stage. Here are some pics of the stage.

Stage in construction

Stage in its completed form awaiting carpeting at a later date

Another pic of the stage and screen (I took the screen out of the frame so it would not get damaged, and wrap in plastic to keep from getting dirty)

A fun fact for the stage: The stage took a little over 900 pounds of sand to fill the stage. This should take care of any vibrations that would have come from the stage.
The plan is to have the speakers standing on the stage but hidden behind a wall with black speaker fabric over it.

I have a question about speaker placement for my surrounds before I run the speaker wire. I have the Klipsch RS-52's, which is a Wide Dispersion Surround Technology speaker.

Klipsch RS-52

Surround speaker locations are in yellow. Here is the first step using 5.1 surround with all Klipsch speakers.

Here is the surrounds with added Infinity bookshelves to complete the 7.1 surround.

Let me know which I should do. I could always wire for 7.1 and when the money becomes available I can then put in the last pair of Klipsch speakers for full 7.1?

Any thoughts or suggestions on this would be great!

Thanks,
JJ

Congratulations on the project. It's progressing nicely.

I see you have put a lot of money into a great set of speakers but have you thought about a sub upgrade? That little 12" RCA won't keep up with those Klipsh speakers. It sure won't pressurize a room of that size. My theater room is 16x25 and I use a pair of DIY 15" subs with a pro amp. It isn't enough for action movies. I've got four custom built 18's on order as an upgrade.

JJMJ71 · 07-19-2007, 04:48 PM

Thanks for the compliment Robert!

Yes, I plan on doing something with new subs not 100% sure yet. I will see what is left in the budget as I get closer to finishing the project and see if I could buy or build something a little better than what I have now. If nothing else at least get another one to help out the RCA!

Another question, if I split the low level line to many times would I start running into problems? An example would be: splitting out three ways to go to two powered subs and a buttkicker amp.

Also, what kind of cost are you looking at for 15" or 18" subs and either a power plate or an amp?

Thanks,
JJ

Robert_J · 07-19-2007, 06:43 PM

My 15's look EXACTLY like a TC 3000 and cost me a total of $250 each for the drivers. I got lucky and found some surplus motors (the magnet structure) made by TC Sounds for another company. They are close enough that it doesn't matter to me. If you want to get an awsome sub, jump on the deal in the link. It will disappear in a day or two since TC Sounds is raising prices by 30% to 50%.

My four 18's on order are another deal. Again, I got surplus TC Sounds neodymium motors (scrool down here to see both of the motors types I have - link). I've contacted another company that is selling me 18" baskets and their 18" recone kit modified to work in an infinite baffle alignment. They will cost me a total of $200 each. If you can't find a deal like this, great drivers are available starting around $100 and going up to $1,000. Find a budget and how much space you are willing to give up and anyone in the DIY section can help you design a great sub.

Plate amps are nice but a pro amp from Behringer, QSC or Crown has a great watts to dollars ratio. An EP-2500 (about 1,000w x 2 or 2,000w x 1) costs about $320. Crown amps will cost up to $1,000 but they will deliver up to 4,000w x 1. Additional circuits to your room are required to handle an amp like that. I even run my EP-2500 on a dedicated 20amp circuit.
The BK amp that you have is has been used to power some of these monster subs. But recent testing has shown higher than acceptable (to certain crowds) distortion.

Splitting the LFE signal is not a big deal as long as you use quality cables and splitters and have enough voltage on your LFE output. I split mine 2 ways now and I have it set at -2. I'm also running it through a Behringer Feedback Destroyer (I use the parametric EQ function to smooth the sub's response) and it can boost the signal some.
