Your Active Speaker Designs / One more try - 4 way
Last post by yoke - April 24, 2024, 04:16:48 PMHi
Here is one more try, but this time more complex
just test cabinets
whell, thay are test cabinets for the last year + ...as I'm a little lazy and undetermined how to procide with final design but will get there...eventually
basic informations :
- RAAL 140-15D - Hypex NC100HF
- Satori MW13TX-8 in 6L - Hypex NC252MP - one half
- 2 x Satori MW19TX-8 in 18L - Hypex NC252MP - other half
- 2 x SBa SW26DBAC76-8 in 16L (with linkwitz transform) - Hypex NC500MP
All closed box design
Sound is really nice
But will try 2 x Satori MW19TX-8 in 50L bass refleks - just to see what I will get
and 1 x SBa SW26DBAC76-8 in 12L, I have the filing that 8L for it is just a too little...will try...
Here are some videos
I know that you can't judge sound by youtube videos, recorder on mobile phone, played on one or so
but it can give you some idea about the sound
I like to watch them, and like to record them, but I know the limitations of them
will get back once I make some progres

The Dark Room / Re: Duntech Sovereigns to feat...
Last post by Tranquility Bass - April 07, 2024, 05:52:26 PMThis is disappopinting. A classic bait and switch tactic 
First entice the punters with a legendary speaker such as the Duntech Sovereigns and then change it at the last moment to their latest offering - a design which had nothing to do with the late John Dunlavy. Even the picture looks photo-shopped ! Not a good look I am afraid

Halcro & Duntech & Döhmann
The best of Australian – maybe the best in the world!
This unmissable audio suite will host Duntech's brand-new Princess loudspeakers – $120,000 floorstanders that take their lead from the company's legendary Sovereigns, acknowledged by experts as the most accurate in the world. With the drivers symmetrically arranged on a vertical axis and time aligned, you have to hear these speakers!
The power comes from Halcro's very latest reference amplification, a triumph of form and function, unique in its imagination of what an amplifier is and how to puh the boundaries of technology.
The third Aussie legend is analogue playback courtesy of a Döhmann Helix turntable, engineered to deliver unparalleled performance in analogue playback and is the result of many years of research, development, collaboration and listening by internationally acclaimed analogue designer Mark Döhmann and his team.
It's an Australian supersystem not to be missed!

News Updates / Is Digital Audio Transmission ...
Last post by Tranquility Bass - March 19, 2024, 06:14:13 PMFor those fake review websites and infuencers that keep promoting "audio-file" network switches please get your facts straight and stop spreading mistruths and propaganda just because it is profitable for you to do so. That is no excuse to do it.
Unlike these fake reviewers and as someone that has actually designed DAC and DSP hardware all I can say is that once those 'ones' and 'zeros' are re-assembled inside a buffer within a DAC or DSP, the electronics does not care where they came from. Whether it's an S/PDIF, Toslink, USB or ethernet connection via streamer and network switch etc it makes no difference to the DAC hardware how they got there as long as there are no errors in the data then each source will produce an identical result and this can be measured as well !
And there in lies the rub. These fake review websites rarely measure anything if at all. Instead they will come up with a whole lot of lame excuses as to why they should not measure anything which is contrary to the people who design the hardware and/or the silicon used in most modern electronic devices. None of their lame excuses stands up to any scrutiny which should be a red flag to anyone reading it. What these people are doing is sending the industry back to the dark-ages and promoting a whole new industry of snake-oil merchants, snake-oil products, scam artists and spivs.
The only caveat here is that different devices may use different levels of isolation with the possibility of passing noise into the connecting device. However this all should be clearly measurable but of course if you don't measure anything then how would you know ? Of course this aspect which is usually the focus of most of these fake reviews has no bearing on the end sound quality. And changes in someones subjective interpretation of sound-stage is certainly not a reliable performance metric !!

News Updates / Re: Why we would never use a D...
Last post by Tranquility Bass - March 14, 2024, 02:11:50 PMAnd from DEQX's own white paper !!
Yes Mr DEQX, the off-axis response is very important especially when trying to deploy steep slope linear-phase crossovers. Well and truly busted Mr DEQX
QuoteIn consumer speakers where crossover slopes of typically 12dB/octave are used, the same sound is coming from both drivers, typically for an octave above and below the crossover frequency. Unless these sources are perfectly timed to meet in phase with each other (time aligned), the resulting mix of sound will produce 'comb filtering', which can sound 'nasal' or 'flanged'.
Another problem has also been introduced by using multiple drivers to reproduce sound – a single instrument may now sound like it is coming from different places. This results in poor off-axis performance because varying degrees of summation and cancellation occur depending on the relative distance between each driver - a phenomenon known as 'lobing'. Because the woofer is often physically placed further back than the tweeter, this lobing is also non-symmetrical in the vertical plane. The loudspeaker's off-axis performance is important because although this is not necessarily what is heard directly, it is ultimately heard because of its coupling into the room.
QuoteTHE DEQX SOLUTION
The active DEQX crossover and correction processors provide help to resolve the problems mentioned above at a number of levels. Although impractical even in 'active' analogue crossovers, DEQX provides true linear phase very high-order crossovers that provide absolutely precise time alignment and phase coherence between drivers, while limiting the 'bleed' of similar frequencies over the crossover region so that lobbing effects occur only at the imperceptibly narrow crossover region, and dispersion patterns remain similar between drivers.
Yes Mr DEQX, the off-axis response is very important especially when trying to deploy steep slope linear-phase crossovers. Well and truly busted Mr DEQX

Last post by Tranquility Bass - March 13, 2024, 11:17:02 PMHere is a blast from the past from my thread on diyaudio where I was trying to mind my own business on diyaudio but the tentacles from stereonet weren't very far away A DEQX fanboy coming out of the woodwork desperately trying to sway people away from buying my preamp at the time of the pre-order for the UP2 and UPP around late 2019 which is about the same time DEQX decided to offer a discount to celebrate an odd 21 year anniversary. Hmmm, funny about that

Well I have got bad news for you. I have three good reasons why you should AVOID using a linear phase crossover. This should change your mind

QuoteSecond, what I really like about my DEQX crossover at the moment is the implementation of linear-phase crossovers (FIR). The software treats it just the same as Linkwitz or Butterworth crossovers. Just choose it from the list, that simple. All other DSP solutions so far expect you to be a DSP expert to be able to implement linear phase crossovers. I was looking for this in audioweaver but so far have not found it yet. Maybe I'm missing something. Now before anyone likes to discuss the downsides of linear phase crossovers and why I would want them but there is only one simple answer: Because it sounds better in my system and except from linear phase crossover I can't think of anything why I would need the amount of DSP power that is on offer in the Ultimate Preamp

Last post by Tranquility Bass - March 07, 2024, 06:39:29 PMWhy a single amplifier driving a passive speaker is such a bad idea but nobody is talking about the elephant in the room !! Maybe if your amplifier is carved out of a solid block of aluminium billet, or you buy some uber expensive speaker cables, or use some cable lifters or even use a grounding box it may solve these fundamental issues but wishful thinking never solved any technical problems

Last post by Tranquility Bass - March 06, 2024, 06:28:48 PMHas anyone noticed how stereonet starts flogging tickets to their show right at the time Australia Hifi hosts their show even though stereonet's show is 31 weeks away ?? That's what they do
And see what they have this year that is definitely worth going to see
