Romy, reading back at my previous post you are correct, I was not leaving any wriggle room and was talking in absolutes. I apologise and will try to not post unless I at least have time to reread what I've written, or better yet prepare a post with ...

Bill has achieved excellent bass with his acoustic treatment. Everything seems fine; everyone nods approvingly. We convince ourselves that the secret lies in how bass reflects off the back wall, and Bil...

Bill, Romy,This is my solution to the bass, see them on the walls in this photo:Romy in particular, note the all steel construction. There is some foam in them behind the steel plate and the entire trap is only about 4"-5" wide. These bass traps do...

[quote user="Romy the Cat"]Anthony,I have much to share about my impressions and feelings regarding your project, but I’ll save that conversation for another time. For now, I’d like to address one specific technical point. I wrote about it quite some...

[quote user="Paul S"]Good job, Anthony! First Class installation! How low do you run your lowest S2s, again?Best regards,Paul S[/quote]Thanks Paul. Lowest S2's in the 250Hz horn are a narrow first order bandpass centred at about 800Hz from memory. ...

The higher SPL tuning of the Melquiades filters give me tremendous bass flexibility on which I am yet to capitalise. Currently, my installation has four bass channels, only the lowest is not driven by Melquiades:Upperbass 100Hz - 1kHz - time aligned...

Whenever you have a large project such as this you always look back and wish there were some things you did a little bit differently. I have a few minor issues with the physical layout of my versions of the actual Melquiades DSET amplifiers, but...

An opportunity came along to trial a couple of dacs higher up the ladder of the dac which I already owned. The opportunity also extended to trial a newly released preamplifier from the same stable. I trialled the dacs in my room over several weeks ...
|
|
Like the time periods B.C. and A.C., I now think of my installation in terms of Before Preamplifier (B.P.) and After Preamplifier (A.P.).As discussed on these pages, I built a hybrid 10Y DHT preamplifier that had more more gain than the Placette Line...

So, this year I've been steadily finalising the installation of Macondo and Melquiades into my room. It seems as though there is always more to do for perfection, but the end is very close now. There have been plenty of building and measuring and ev...

Not sure if I mentioned this before, in my solar/battery system, which is similar to Bills, sound is best at night when there is no sun and the inverter is drawing only from the batteries, but during the day with zero clouds the sound is really com...

The Trinnov is in my system for the first time tonight. Just a rough optimization done and running 8 channels in Auro3D configuration including Macondo, 2 front height, two rear height, two surround...very rushed...no great care taken setting things...

Bill, I do not think that what you describing is contribution of solar power. The actionable factors in your playback is new regenerator and new battery. [/quote]For sure it is the inverter and battery contributing to t...
|

Bill, good to hear. Enphase are from California but your batteries, inverter etc. could be from anywhere. I have an off-grid Enphase based solar/battery system for my office which includes the audio/video. My improvements are not in the same leagu...

Thanks for the tips Bill. No Trinnov guy to do the setup at this stage but apparently there is access to Trinnov in France. I may end up getting the salesman here...not sure...he is a long way away. The unit is sitting in a box downstairs patientl...

Romy, the Vitavox quip was a cheap remark following some visits to some expensive audio installations. The two major areas where I felt these installations were lacking was right where the S2's and 15" in my system are implemented...the Vitavox driv...
|
|
Bill, in my experience I am finding it harder and harder to understate what the Vitavox S2 and K15/40 bring to the sound of a capable playback system. ...

Yes, my Trinnov is brand new with the all the current bits.My thoughts with that video were towards the conundrum of what has clicked to get your system to its current level of performance. When I was watching the video I thought there were several ...

Was looking on line to see how Trinnov changed the adc/dacs inside the altitude and found this rather interesting video. Bill, Romy, does any of this ring true?http://tempuri.org/tempuri.html...
|

Jarek, I currently do not do RI. The immersive channels have only been used for audio visual stuff thus far. I purchased a Lexicon somethinorother to try RI but never got there to take it out of the box. The Trinnov suits my purposes as I can use ...

A few months ago I met a statement in one on my videos bass channels should not be driven by the same crossoveed signal as a rest of the system. In my view it is the key. In my current view it needs to be very de...
|
|
Jarek, I would try to listen to any immersive channel before you buy too many of them as in my opinion they need to at least roughly match your main speakers in the type of sound they produce. Here, I've had several hi-end'ish standmounts and booksh...

Now that is an interview. ...

I presently have three bass channels: Upperbass horn; Bass Cannons with 8x Scanspeak 10" per side; midbass with 3 x K15/40 per side. I have excellent response down to 30Hz or so all run by DSET. Bass is spectacular now that the midbass channel is ...
|
|
Romy, I've put so much work into the line level filters that I am very reluctant to set them aside for digital if I was able to. 7 channels each side + 7 immersive channels + 2 immersive subwoofers = 23 channels total and the Trinnov16 only has 20 ...
|
|
I am building subwoofers right at this moment. Have gone with a modern 18" that I've never heard and a large AB amp to power them. Will be low passed somewhere around 30Hz so I doubt that driver quality will matter... at least I hope not. This w...

Dual voice coils Romy. Not sure if the Auros have dvc but if they do then perhaps different amps on each voice coil....
|

Apparently there were two type of S2 diaphragms made: aluminium with paper former till serial number 4941 in May 1972 and the direct wound type with polyester surround. Apparently the S5/S6 diaphragms are interchangeable and are also direct wound b...
