MKSOUND_HT Posted June 10, 2024 Posted June 10, 2024 (edited) Hey all, i've always been fascinated with the idea of a david vs goliath system, where I combine either say big amps with small speakers or big subwoofers with small but equally as effective speakers. My original "David vs Goliath" which can be viewed here combined MK Sound M7 speakers, MK Sound M5 speakers and some SVS PC2000 Pro subwoofers. It was a great system and loved it. Shortly after I changed to MK Sound S150 MK2 speakers and Dual V15+ subwoofers (plus rotel amps) which was an amazing setup but a few curveballs in life mean't i would need to either sell up or downgrade. I made the most of what I could and combined some of my ideas to build a more budget friendly David VS Goliath Round 2. Here is that system | SPEAKERS | LCR - MK Sound M7 Speakers x 3 Surrounds - MK Sound M7 Speakers x 2 | AMPLIFICATION / PROCESSOR | ToneWinner AT-300 Processor 7.3.6 ToneWinner AD-5100PA+ 5 Channel Power Amplifier | SUBWOOFERS / TACTILE TRANSDUCERS | MK Sound V15+ Subwoofers x2 Dayton Audio BST300-EX Bass Tactile Transducers Dayton Audio APA1200DSP Subwoofer Amp | DISPLAY | 75" Samsung RU7100 4K TV (Would love to upgrade this one day to a 98" 4k TV or Laser projection tv). Tv is currently on floor, I am just waiting on a Vesa floor stand for it this week. Edited June 13, 2024 by MKSOUND_HT 7 1
MKSOUND_HT Posted June 13, 2024 Author Posted June 13, 2024 Hey all, just had a little update on the system. I've wanted a standalone vesa stand/cart to be able to put my tv on. I love mounting to the wall using vesa bracket but this way I will be able to change tv screens and have a bit more adjustability if I decide to move the room around its a TV Stand cart I got off ebay. It supports upto 80kg I believe. My dream of one day having a 98" TV will be great and should fit on this stand too hopefully haha I am also working on a 3d printed bracket for this part of my couch. Since the Dayton Audio BST-300EX Tactile transducers will be mounted to this section of the couch, I wanted to 3d print a plate to cover this section and have binding posts. The BST300-EX are 4ohm each, so I will have 2 sets of binding posts at the back and run them to my Dayton Audio APA1200DSP subwoofer amp (its 2 channel, one for each). Here is a small draft of the plate I am working on. It still needs screw holes to attach to the couch and maybe a few other connections for future proofing. I would love to make it out of 2 pieces (and will be black). I love creating stuff like this. Just adds a bit of your own touch to the items. 4
MKSOUND_HT Posted June 16, 2024 Author Posted June 16, 2024 (edited) Hey all, I've been super excited to share this. I have just got 2 Dayton BST-300EX and i've figured out that a Startech Server mount Vesa monitor Bracket fits perfectly inbetween most 2 seater couches with a centre console. I put Furniture nuts from the back of the wood of the centre console frame so i can take it off and on as much as needed without having to worry about threads in the wood. I 3d printed a little plate for the binding posts too (one for each). My amp only has 2x 8 ohm or 1x bridged 4 ohm (Dayton APA1200 DSP sub amp) so I have had to run seperate channels, but if i get another 2 at some stage I will likely run them in a total of 4 ohms (2x in 8 ohms and 2x in 8 ohms for combined 4 ohm load). Here is my attempted Double decker bus. That is 2 of the star tech server vesa monitor brackets clamped together. This will allow me to add another set of BST300 EX under the bracket and still mount it within the 1 piece. I 3d printed a little bracket since only 2 of the vesa mounts match the BST300EX (strangely it matches perfectly for the Buttkicker LFE). While i was there I also mounted a bluetooth accelerometer so it will be easy to tune the buttkickers. And since its hard mounted it will have a lot more accurate vibrations. I still need to do EQ'ing but my APA1200DSP doesn't have much adjustments (and none below 20hz) so I might have to get a dayton audio LF DLP to assist. Edited June 16, 2024 by MKSOUND_HT 4

Nicely done @MKSOUND_HT I cant wait to get a 100inch tv to replace my current screen in the coming years! Thank you so much buddy. Really appreciate it. I've been contemplating adding an extra 4 channels (front wides and side surrounds) haha.
MrBurns84 Posted June 17, 2024 Posted June 17, 2024 Actually, been meaning to ask.. How did you find the PC2000's sound? as compared to the M&Ks? 1
Hi-Fi Whipped Posted June 19, 2024 Posted June 19, 2024 Awesome work, I use MK sound speakers too and I have no doubt that the M7s would punch well above their weight, particularly given the two massive subs you are running! 1
MKSOUND_HT Posted July 5, 2024 Author Posted July 5, 2024 (edited) My deepest apologies for the delays in my responses below. On 18/06/2024 at 9:49 AM, MrBurns84 said: Actually, been meaning to ask.. How did you find the PC2000's sound? as compared to the M&Ks? That is a great question indeed. I must admit there was a bit of time between the PC2000 pro's and when I got the M&K's, but I reckon the M&K's maybe sounded a bit cleaner, this was likely due to the sealed enclosures. I think the V15+ still went down to 18hz or so but they are relying more on in room gain I think. I think the SVS definitely dug deeper at 17-23hz. I always wanted to try out a SVS PC4000 one day (or two haha). I've been a huge fan of the Sono tube subwoofers from the early days of DIY i guess hahaha.

Oh thank u heaps. Its so nice to hear that you are also a big MK Sound fan. I was wondering which gen S150's you currently own? I had the Gen 2 model S150 silver logo at the bottom) and foam between the tweeters. I reckon the heritage and the amazing memories of seeing this equipment when I was too young to afford it (I think at all ages to afford it haha) that you are one day owning the equipment you dreamt of feels amazing.

MKSOUND_HT Posted April 2 Author Posted April 2 Hey all, Its been ages since my last update so i thought i might pop in a few details for any readers My Dayton Audio APA1200DSP subwoofer amp that was powering the Dayton Audio BST300-EX Bass Tactile Transducers has unfortunately failed. I am just working at getting a warranty claim on it. I think i might return back to a Dayton Audio SA1000 amp, but since I am running 2x 4 ohm bass transducers, I will only be able to get 500w at 8 ohms out of the amp (only half of what it can do at 950w at 4 ohms). It won't really make much difference if i was to get 2 more Dayton shakers (i have the space for it in the centre console), but even with a total load of 4x 8 ohms i will still only be giving each bass shaker 950w / 4 (50w less if i ran 2). Just feels funny to not use up all the power. I also had the idea of integrating the plate amplifier to the back of the couch (there is actually heaps of space behind there), but problem is the width of the centre section is 28cm and the plate amp i had in mind is 30cm (so it won't look neat like I was hoping). Not to mention a Interconnect at the back and a power plug (i could use right angle interconnect).
MKSOUND_HT Posted April 10 Author Posted April 10 I've been running a 75" Samsung RU7100 on a AV stand and really love it. I am about 3m away from the tv, but since i've run a 150" projection screen I still miss that size (i'm lilterally half the size of the screen before). I've been considering a TV instead of a projector, and the biggest I could afford would be 100%. I did some photoshops to show the difference. Not quite sure what option to go for atm Current Setup - 75" TV Photoshop of 100" TV Half half - 75" and 100" Previous setup with 150" Projection screen (was a bit too big I think from the 3m seating distance especially for games)
MrBurns84 Posted April 11 Posted April 11 For movies, at a 3m seating distance, i feel that a 120inch screen (max) is watchable. I sit 3m's away from my 100-inch screen and at times i do feel that i'd wished to have gone with a 120inch screen. I wouldn't bother with a 110inch as it wasn't noticeable over the 100inch. A friend of mine replaced his old 85inch screen with a 85inch tv recently and now regretted his decision. There's something nostalgic about watching a movie on a projector screen on 1080p res over 4k high def tv. Since you do game, Tv is preferable due to higher refresh rates, imo.

Long time no speaky Thanks very much for the reply. Hope you are keeping well on your side. I've been investigating Ultra throw projectors as well but the price is quite a lot higher than the 2 projectors I had in mind. Epson EHTW-7100 and Epson EHTW-6520 I've got this wierd fear of mercury based lamps on bulb projectors if they ever explode (i have a very absorbant mind so when I read something its hard to forget once I know something). This was one of the reason the Epson EH-LS650B Laser 4Ke Ultra short Throw Projector was also another choice, and I could do 120" quite easily. Logistically I think getting a 100" 4K tv would be very difficult getting it in the front door, so I think thats one of the reasons in the back of my mind I wasn't so keen. From the pics I could find, they have the tv on a pallet haha: My partner gave me the 75" Samsung RU7100 you see in the first pictures, so it has a special place in my heart. But there is just this feeling in the back of my heart that there is an itch only a big screen (100"+ ) can suffice. 1 1
Hi-Fi Whipped Posted April 14 Posted April 14 Yeh once you've had a 100" plus screen size I'd think it would very hard to go smaller unless I had no choice, spent my whole life wanting a room that could facilitate a large PJ screen and now the 135" screen at about 4m seems spot on. Could you have purchased a smaller PJ screen and kept the PJ you had or did the numbers just not work?
