Last week I have a privilege to audit Winthur new setup with 2 additional 10" DIY Subs. This was my 3rd visit to his place...
I remember my 2nd visit to his place with some re-align of speaker placement plus some tweaking on 2 18" subs the bass i feel can go much deeper and with lot of rumbling... his surround sound & bass had definitely improve a lot after my first visit.

This time with just 2 additional 10" subs... he has bring his bass to another level... this time the bass not only go deep but also play cleaner and tighter plus the rumbling feel.... this kind of movie experience is where you don't get it from the cinema... 8)
For those members who had visit him once should pay him a visit again.
Thanks Winthur, i enjoy every moment of your demo session.
Cheer!

Thanks Kennyluck2000 for the kind words. Could not have done it without the comments, feedbacks, constant questioning and answers in order to reach where it is today.

not only to kennyluck2000, but also to other members who had spent precious time in visiting my humble nest for audit.

still a little bit more to go before doing another Open house again after the arrival of diffuser panels arrive :)

Thanks all once again

yah agree with you Kenny bro.

Today happen to visit Winthur the 3rd time in a row. Got some solid stuff from him.

My Jaws drop.... The " presence " is really good.
The up front Dual 10inchers mid range drivers did perform with solid good quality bass
My thoughts as below:

1. The Twin 10 inchers sound natural and " felt " punch. :)
2.Have never heard such a dual combination DIY 10inchers
   which Mids bass up to par or even > than some 12" subs out there.
3. The back 2 18 DIY inchers will rumble with Wind. :)
4. Driven by Model NX6000d Behringer power amp ( Channel A &B ) , they look really outstanding.

Really good job Winthur. V enjoyable session thumbs up.

Outstanding Amp :)
Saw on web this power amplifier delivers 3,000 watts/channel into 4 ohms or 1,600 watts/channel into 8 ohms,
giving you plenty of headroom to work with.

Ok... i finally had time to do calibration last night using the Marantz MM8077 power amplifier. I bought this power amp due to the following reason:

1. Testing, since i've seen quite a lot of review that this power amp is match make with marantz AVP and since i am using one, i would like to give it a try

2. Sound signature, to prove that is it indeed "heavenly match"

3. Additional channel, the more the merrier even though not using, who know i may need in future? :P

The specs can be found here https://www.us.marantz.com/us/products/pages/ProductDetails.aspx?CatId=avseparates&ProductId=MM8077

The channels are pretty pack to one another to be honest. As compared to the previous emotiva XPA 6 Gen 3 which i am using which are pretty spaced out. The Marantz has a left right switch vs a flip switch on the emotiva for balance and unbalance input.

The binding post seems a bit flimsy but it does the work if you using the banana plugs which i believe most of us do.

It has a little cooling fan on the right which i am not sure if it is even activated, since i am using the AC infinity T10, the temperature does not go as high as emotiva is what i notice despite playing at high volume.

The sound (Audyssey with dynamic vol and dynamic EQ off, marantz power amp for all floor speakers and emotiva for all heights speakers):
In my personal opinion, the sound is not as harsh when playing loud. using SPL meter playing at 80 to 85db ish, the volume from my marantz 8805 is around -14 to -13...which is already pretty loud.

For Movies, what amaze me is despite playing loud, the clarity, dynamics of high and low and the surrounds sounded liquid smooth and clear. Tested incredible hulk and john wicked 2, the sound is so clear and smooth, it is precise and i trust that at certain scene, some details i do noticed with the marantz but not the emotiva...or maybe it's just me for not noticing.... example, you can actually hear something when reeves is walking in the tunnel before meeting the lady whom showed the middle finger before the gun fight starts.

For music, all i can say is it's undeniably excellent! I can say they (MM8077 and 8805) is made for each other! May be there are better power amp out there which i've not heard or tested in my environment before but i can say that for now using 8077, when playing vocals and musical, maaaaan it just sound so pleasing and good! it's buttery smooth, no fatigue at all, listening at -23db is just right for my room. some tracks which i've played became even more lively, music sounded coming from surround sides and overhead but its actually stereo. For the first time ever i swear my Mrs actually commented about my gears saying "how come this track sounded so nice now?" We sat on the couch and listened for about 3 hours until she fell asleep.

I am not sure if emotiva sounded distorted to me when playing high volume but after a movie with emotiva at -15db and music at -22db, it does gives a little fatigue at the end. Do note that my dynamic EQ and vol is off.

During the audessey calibration pulse sound (pew pew pew), i do noticed that the pulse marantz gaves is like "smooth, taking its time, no hurry, soft," kind of feeling. The emotiva is like "com'on let me give all of it, i have lots to give, chiong arrrrr" kind of feeling LOL. But overall after the audyssey, all volume definitely balance out, which eases my worries for a bit. My guess is since emotiva is a USA machine, it should be more daring in producing anything.

Its not that emotiva is not good, emotiva is definitely showing that "look, give it to me and i can do more" kind of feel. i guess my preference just changed from hearing all action and loud, to hearing the details but at the same time loud. i enjoy more details now despite at low or loud volume. :) The watts does plays a part i agree but after calculating the distance, the 1w/1m and sencitivity of my speakers, it may not require so much of a power per channel at the end of the day. Depending at what is being output at the time of moment also.

I'm doing little change, tweaks here and there... as soon as i am done, i hope to invite forum members to my place for some refreshments and enjoy the movie + music at the same time.

Alright, so it's been a while now since i've updated this thread. I've been trying to get things up and in place as fast as i can before doing the next invite session, however new things keep "appearing" and being added to my home inventory lolx... while pending for my last piece of equipment, which are the Apollon Audio Stereo Amplifier NC800SL for my front left and right speakers, as well as the Apollon Audio Monoblock NC800SLM for my center, i thought i share my little journey here (again) since my very first open house.  :)

After hearing the many senpais suggestion and opinion here in this forum, i have made some changes to my listening environment, the 3 major target areas are

1. add more ceiling speakers in achieving the 3 sound formats DTS:X, Atmos and Auro3D
2. change my 18" subwoofer cabinet size
3. add diffusers to narrow sound gaps.

After hearing a few senpai's setup, i must say they are ALL AWESOME! Well, its a journey, never a destination... and i hope i can share my journey here after gaining some experience from the senpais lol

Point 1.
I started off with Auro3D format layout, since i can achieve the sound bubble of DTS:X as well as Auro3D with Top surround VOG and Center Height. I thought i can get away when introducing Atmos by "matrixing" them....This proves me wrong because nothing can beat the sound FROM the correct speaker placement according to guidelines. Following as close as i can get with WAF, the result in what i've achieved are not only having DTS:X as well as Auro3D with Top surround VOG and center height, but also Atmos.

I've added top middle left and right speakers so atmos can be played from the respective speakers :P


So in total, i am having 8 height speakers. Front heights and rear heights for DTS:X, Auro3D, Atmos, Top middle for Atmos, and finally VOG and center height for Auro3D. This is done so that i can enjoy all sound formats.


Here is the close up for the top middle left


Here is the close up for top middle right. Now because i wanted to make sure top middle right is the same level as my top middle left which is mounted onto false ceiling, i made one block same drop down length so that the same measurement and distance can be properly measure by room correction software audyssey.


Overall experience improves because Atmos can be properly played to its respective channel.


Point 2.
The main reason why i change cabinet size is to reduce the potential/slightest chance of port chuffing. After heeding a bro advice wechnivag, i decided to go for it to make a change of the cabinet that has been with me for the past 4 years coming 5.

This is the original cab with one port. Dismantling the subwoofer driver (TC Sound ultra 5400) is never easy due to its weight. Thanks to bro synthesis help in this. i can rem him saying, "the first time i did this cab i find it massive, now it seems a norm to me" lol... experience level up there i see.


The below is the final result of the "upgraded cab". With 2 ports now, playing edge of tomorrow will bring my neighbors come knocking on my door. :P
The subs are powered by the Behringer NX6000D DSP Class D power amp. (a bit of ko yoh here, we are the dealer for this lol)






Overall experience again improves. Digs deeper, prevents chuffing noise, more extensions i guess :)  gotta special thanks for kennyluck here. Due to my tennis elbow on my left arm, he is really super duper kind to help me send back the cabs and put back the drivers, yet got his finger hurt. 😓 Sincerely thank you Kenny!!!


Point 3.
Being skeptical about having diffusers then, what i have in my living hall are only absorbers. so what makes me think twice about having them... bro ronildoq's setup!! Hear to believe! No doubt absorbers, curtains, fabric sofas etc etc can reduce noise floors, too much of it makes the room sound dead.

Having a low noise floor brings out the finest details even at a lower listening volume, which what bro ronildoq and bro desray says (i believe majority of us would agree), reduces listening fatigue and at the same time can still have decent conversation when movie is playing. Now the magic of having diffusers are, despite the room sounding "dead" without any movie playing in the living hall, everything comes so much alive the moment a movie started. Sound dispersion, the environments, the sound panning all around MLP leaving minor to no sound gaps, listen to stereo, stereo music sounded so much like also coming from surround speakers, the WHOLE experience just up by another level (well maybe a little level).

This is unboxing picture. (yes, another bit of ko yoh here again lol, we are the only dealer for soundbox acoustic in SG lol)




The specs as below in brief for the white color:
-Material made of Polymer (with large molecules) with E0 Eco friendly paint over
-Full band frequency diffuser
-QRD arrays
-Improves sound fullness and surroundings sense without hurting natural RT60
-size is H1.2m x W30cm x D10cm weighing less than 2.8KG per piece.

The specs as below in brief for the grey color:
-Material made of Polymer (with large molecules) with E0 Eco friendly paint over
-Medium frequency absorber
-Polymer/polyether polyol fire retardant acoustic foam in between
-Deal with low freq around 300hz to 800hz
-size is H1.2m x W30cm x D10cm weighing less than 1.6KG per piece.



This is the before treatment pic


This is the after treatment pic


This is the overall front stage pic (just imagine flat wall and my glass partition all around :D)


Overall experience definitely improves by leaps and bounds! Sound gaps between speakers become narrower, sound panning between speakers improved thus sound is more immersive, stereo sound stage widens, it becomes more alive and is like listening with surrounds speakers but yet only stereo, all while remaining a low noise floor!

I would like to thanks all the bros here whom had invited me to their place to gain all these experience which then i can apply to my room.

As much as i wanted too to also invite bros to my place, i still waiting for my last toy for this year (yet) to arrive ,hopefully next 1 to 2 weeks time. Hopefully the NC800SL hypex NC500 based amp, with 2 x Sonic imagery 990ENH op amp will live up to its name for my Front Left, Right Center.

I look so forward for members to drop by my place once again, and at the same time taste the fragrance home made nonya kueh kueh that my wife made :D

Till then~

My apology, i am not sure why the pictures are so HUGE omg... hope someone can help to correct me by telling me how to make it smaller automatically.
