Newly completed HT
« on: 4 Jan 2024, 03:50 pm »
I thought I would share my recently completed dedicated HT.

I am a long time symphony orchestral musician who has at the age of 69(soon to be 70 this month) decided to build a dedicated HT(go figure...) which I have just finished about a month ago. The room is 16' x 22' and I am running a 9.2.4 system. The original thought was 90% movies and 10% music.  That ratio has shifted to about 75/25.

Before I start, a little about this room... I am an avid woodworker with a full shop above my garage. Except for drywall work, everything in this room was made by me. The first thing I made were the speaker stands for the surround bed layer.  If you look at the pictures below you will notice that all of the Chane 740's in the bed layer are upside down(meaning the port is up). I asked Jon Lane(owner of Chane Music & Cinema) about this and he said to try them oriented this way. I could not tell the difference either way so it made easier when designing the stands. The stands are made of maple cabinet grade plywood with solid maple on the outside and top and bottom.

Room treatments are a must to give any speaker a chance at greatness. I was going to go the GIK Acoustics route but through an audio buddy of mine(thanks TedB!), I contacted Jeff Hedback out of Indianapolis who is a musician and recording studio designer. He will also design dedicated home listening rooms although it isn't his main gig. I sent him all the info he requested regarding my room and he came up with a design after computer modeling my room. I cannot go too deep into how I constructed as it wouldn't be fair to Jeff.

I built a false wall to house my 128" 2:35.1 scope screen, LCR, and the front sub. There are two wings at 30 degrees which house the left and right speakers. The false wall and extending 5 more feet out, the walls & ceiling are covered with panels of triple black velvet. The rest of the walls and an 8'x8' section of the ceiling are made of diffusion panels constructed up in my shop. The only drywall is on the ceiling and 12" on both the top and bottom of the walls. The space behind the screen/false wall is also acoustically treated. The four ATMOS 740's are all oriented to the main listening position.

There are six seats, three on the main floor and three on a 13" riser. The riser is filled with insulation. I also built a bass soffit(filled with rockwool) that circles the two side and back walls. Cement floor with padding and carpeting.

I took a BIG leap of faith going with Chane Music & Cinema but after some due diligence I went ahead and ordered 3 752's for my LCR, along with 12 740's to complete a 9.2.6 system. After some thought and discussions I decided that having six ATMOS for my size room would actually hinder the sound so I went down to 9.2.4 system.

The Chane 752/740's are an absolute joy to hear on 4k movie multi-channel content. Yes, I ran ARC Genesis on my Anthem AVM 70 so that all the speakers play nice with each other but in my opinion, room correction cannot help a mediocre to bad speaker. The ability to ratchet up the volume with NO adverse effects(other than your ears) is extraordinary.

My two channel listening for the time being is being handled by using a NODE N130 to stream Qobuz via a digital COAX cable to the Anthem AVM 70. I believe that the DACS in the Anthem are being used. Count me impressed by the soundstage the 752's deliver. But in addition to the soundstage, I find the 752's to be an accurate sounding speaker. This is especially important to me when listening to classical music both symphonies and chamber music. Believe me when I say that I know what woodwinds are supposed to sound like as well as the horn section in a Mahler Symphony. The Chane's deliver the goods.

I do believe in speaker break-in. The woofers just have to be played in order to loosen up. The 752's have been changing slightly for the better. I never cared for horn based speakers. I am a devoted soft dome tweeter guy. I don't know Jon's recipe but these 752's sound like no horn-based speakers that I have heard to date. No... I take that back. I heard a great demo of JTR speakers and they were also pretty impressive(at multiples the cost of the Chanes).

The Guarneri String Quartet's Complete Beethoven Quartets sounds pristine. The decay in sound(thanks Jeff) is scary good. Chris Jones' vocals on the album Roadhouses and Automobiles is also fabulous. These speakers don't improve bad recordings. They still sound bad. But man are they good on well recorded material.

In fact, I like the 752's so much that I sold two of the 752's and bought 753's for my left & right speakers.

The pictures below show the original front stage with the Chane 752's and then show the change to the 753's.

You did an incredible job!

Wish I was local so I could hear it!

Your new AVM 90 should take it to a whole other level.

Very impressive! Jeff Hedback does great work as well.

Thanks George and Tom.  The room took me over 3/4th of a year from planning to building it out.  All of the diffusion/velvet panels can be taken off the walls, exposing the studs, so that I have easy access to any wiring.  I used Beau Clip Fasteners to attach the panels to the studs.

I am in the process of building a wood/glass door for my audio gear.

Yes, Jeff Hedback is the real deal!  Well worth the investment!  Even our Golden Retriever "Molly" likes being in this room.  Of course, this means vacuuming a ton more.

Randy,

Can you tell us more about the speakers?

I am not familiar with Chane...

Thanks,

George

George-

My choice of using the Chane's came out of all the in's and out's of planning and building a dedicated HT.  I had never attempted this type of system and just like 2 channel music systems, one can go down the $$$$$ rabbit hole really quickly.  Instead of buying a set of speakers and maybe a sub or two, I was looking at having to purchase 13 speakers along with two subs.  Since I wanted to "hide" the front LCR/sub, I decided to build a false wall.  I therefore was looking for a sealed speaker design for the front LCR.  I also wanted all the speakers to be from the same company so that I could match the sound all the way around the room/ceiling.

This led me to start looking at vendors like Power Sound Audio(PSA), JTR, Arendal, and Chane.  I have heard the JTR's and they would have been my first choice.  However, their cost completely blew my HT build budget to hell!  I also knew that I would not be able to listen to any of the others before buying.

I liked some of Jon Lane's design principals with his 700 Series and decided to buy 3 752 models for my LCR and 10 740 models for everything else.  As I stated, I ended up with 2 753's and 1 752 for my LCR.

The 753 floor stander employ three 8" ScanSpeak woofers.  The woofers are in a sealed alignment.  There is a matching 6.5" midrange paper cone driver.  The tweeter is a prosumer 1" compression driver made by Eighteen Sound.

The 740's are meant to be an on-wall speaker but I built stands as it gave me greater ease when pointing these speakers towards the main listening position.

I am literally blown away when I listen to 4K material from a 4K player.  The Chanes have met all my expectations.  Two channel listening is still a work in progress. I will report back after recalibrating my speakers with my newly acquired AVM90.
