  1. Well I fitted the SC200 amp modules on the weekend and spent yesterday listening to them. It is a little bit clearer mid/top but the biggest difference which I didn't expect was the improvement it made to the bass. The bass just sounds so much better , more of it to begin with but also the quality of it is very good. And it wasn't just the very low notes , it was all bass frequencies that improved. I ended up half of my listening session without the subs going and just the SBA-761's because the bass sounded so good and it was surprising me at th
  2. Ha , I don't have the wife factor to worry about. I built up a subwoofer amp with a 2400w smps power supply with stereo irs2092 class d amp modules , about 400wrms each channel 8 ohm and for the mains I am using my Playmaster Pro Series 3 amp which I bought from Jaycar (when they had audio stuff) and built about 20 years ago , I recently tried some Holton amp modules https://holtonprecisionaudio.com/collections/diy-audio-amplifier-modules/products/hpa-nxv200l-r4-balanced-xlr-input-amplifier-module but I found I preferred the sound of my Playmaster amp so that's what I have been us
  3. My subs are flat down to 20Hz in room so I get all the good stuff down low including what you can't hear but feel , you don't know what you are missing out on if your system doesn't reproduce the lowest notes with authority , for me it's almost the most important aspect of my sound system.
  4. Yes , the speakers on top are for Atmos. This is the link for my subwoofer http://mainkas.tripod.com/page/audio/allmighty/tangen_sub2r.htm I stumbled across this sub over 20 years ago and built one then , that's the one in the photo and I have another one in the opposite corner of the room that I built a few months back. The subwoofer is the cleanest / lowest sub I have heard , I have been to a few live concerts and I think mine sounds better. It shakes the crap out of my house , very good for movies as well. It actually looks a lot l
  5. Yes I will get some pictures and I just realized I don't have a finished picture of my subwoofers , I will get some of those as well.
  6. I fitted the Textreme tweeters on the weekend , I also changed the tweeter level resistor from the 4.7 ohm I previously fitted to a 6.9 ohm as the sensitivity of the new tweeter was higher. Wow , these are impressive tweeters , the airiness has improved a lot as well as percussive higher frequencies and also the stereo imaging has also gone up another level which I didn't expect. I think my main problem with the original tweeter response I was getting was that I came from listening to the Vifa D25AG metal dome tweeter for the last 20 years and was very much used to the
  7. If budget is of concern then definitely console but for best performance/visuals and options PC is the way to go. I have had both PlayStation/Xbox consoles and PC over the years , early on it was a 6 month cycle for PC upgrades to stay up to date and I grew tired of this and moved to consoles for a while , 2 years ago I moved back to PC due to wanting to try out iracing ( irenting , bloody rip-off , crap car handling , Rfactor 2 is so much better ) and have only upgraded once in that 2 year period , so it seems this has slowed down and you don't need to update as frequently to pla
  8. Yes , I had one of those bandpass sub boxes from Jaycar , first sub I owned , had it placed behind the couch and it use to send some good vibes through the body. I ended up making it a ported cabinet and squeezed a 15" JBL Pro Audio driver in there , I still have the cabinet. Unfortunately the original 12" driver didn't survive after a subwoofer amp fault sent the full 80v dc rail to the speaker , that was one burnt voice coil.
  9. Yeah , finally my Sb Acoustic Textreme tweeters will be delivered today from Wes , hopefully I will get a chance to fit them this weekend also I should have the SC200 amp ready to test as well , I will report back in a week or two on the outcome.
  10. As much as I am rooting for Jack and hope he does well I have a sneaky suspicion Bagnaia is going to outclass him this year and I hope I am wrong but I think Jack will loose his factory ride next year due to better performers. Oh Well there is always Remy Gardner on his way up and doing well.
  11. Give Rfactor 2 a go , it's the most realistic handling of any driving simulator , it is way more fun and enjoyable to drive than iracing the only thing letting it down is the online side of things but if you have some friends you can setup a local server and choose your own tracks and cars and race with your mates , this is what I was doing and it was a blast. Now I only play WRC 9 and do the Esports as I am now part of a team (World Erally Racers).
  12. I ended up upgrading to the TrakRacer TR80 rig with my own seat ( Saas Kombat seat , very comfortable) and the inverted pedal mount , the inverted pedal mount works well and the TR80 rig is nice and solid with no flex with lots of adjustability , much much better than the crap RS6 Mach 2 I had.

  13. You could do it the other way but the general convention is the way I described so that full signal level is supplied to the volume adjust and it then reduces the signal to the amp.
  14. I would put it in between the preamp and amp , the volume control part is usually the last thing in the signal chain before the amp. You shouldn't need to alter the pot and if you were wanting to change the max output of the tone module you would need to work out it's gain and change that.
  15. If no preamp then the simplest way is a good quality pot at the line in input of the amps , dual ganged if it's a 2 channel setup. If your source can vary it's volume then that would also do.
  16. Silicon pads were created for convenience so to speed up assembly time but mica washer and paste still have the best thermal transfer properties , I personally try to always use the mica washers and paste.
  17. My stereo subwoofer amp I built using these and it easily drives my subs beyond there physical capabilities. https://connexelectronic.com/product/smps2000rxe/ https://connexelectronic.com/product/irs2092-stereo-amplifier/ My subs have never sounded so good. Also all my amps in my car are class D and it sounds fantastic.
  18. I also wanted to try some SOT-23 surface mount PNP transistors in my Playmaster amp (Q3,Q4) , as the Playmaster PCB is configured for TO-92 through hole , I needed some adapters so I knocked up a PCB , the gerber files for the PCB are on my google drive. Out of curiosity I am also building the Silicon Chip SC200 low distortion amp modules and will give them a try too.
  19. Yes , SB Acoustics TW29TXN-B-8 Textreme tweeters are what I am waiting for from WES components.
  20. Well I have fitted the Playmaster Pro series 3 modules back with the Connex SMPS power supplies and it works very well , no noise and very quiet and weighs quite a bit less. While I was at it I also changed the amp modules input transistors Q3 Q4 (BC556) to KSA992 (different pin out so you need to bend the legs to match) and matched their Beta and Vf , I also cable tied them together with some thermal paste so their thermal properties stay the same. I am now back to the sound I am very happy with , the Holton modules never did it for me and were just very boring to list
  21. I spent yesterday listening to the Holton amp modules. I think I am going to fit the Playmaster pro series 3 modules back as they sounded better to me. I'll give it another week before I decide for sure. The things I liked when I first set up the Playmaster were gone with the Holton modules , the clarity wasn't there compared to the Playmaster , there was no sparkle or excitement to the sound , very boring , maybe good for really bright speakers , oh well only way to find out was to try. Still waiting for the Textreme Tweeters. Cheers
  22. I feel like such a dick. When I rebuilt my subwoofer amp from mono to stereo for dual subs I used a Connex IRS2092 class d stereo amp module , you need to wire it so 1 channel is out of phase with the other channel to avoid bus pumping (class d thing). I had done this but when I was fitting my clipping indicator I discovered I had misread the labelling on the outputs of the amp module and didn't have the inverted channel output swapped around so I actually had one subwoofer out of phase with the other. I had not picked this up as I also fitted the second sub at the same t
  23. I had to make another version of the clipping indicator PCB's (clipping_ind_V2) , I changed the resistors that will dissipate heat to standard size through hole resistors except for R9 which I made a 5W through hole resistor , R4 and R5 can't be 0402 surface mount size as I discovered because of heat , I have tested it and it works well now. I now have the SMPS from Connex so I have everything to rebuild my amp , should be in the next week or so . I am still awaiting the Textreme tweeters to try.
  24. Wow , I am really surprised and impressed. The Denon has Audyssey XT32 calibration and after performing the calibration and limiting the frequency range to 500hz it has done a much better job than MSO did with my dual subwoofers. With MSO I still had one particular strong resonance which I could never quite get rid off with multiple tuning attempts , which was very annoying on certain tracks that used a lot of that frequency as it was noticeably louder than the rest. Now after calibrating with the Denon and the included mic , it has removed the resonant fr
