[quote user="skushino"]Guys, my attention has been elsewhere the past couple of weeks. The catalyst for the original post was to go beyond the usual "speakers in a room" approach, and use the room itself as an integral part of the sound. IB seemed ...

The reason that I built the 6C33C preamp was to explore the 6C33C true musical potential like I did with the 845. Not only did I compare the sound of these tubes in power amp, but also in preamp. The reason is that with power amp you might hit some l...

[quote user="Romy the Cat"] The “expedited” sound
shorten a bit the decay time/volume and makes transients more prevailing. This
is what very commonly audio people feel as “quality” but I degree with it.

Carbon
Jesse,
Looking back I realize my writing wasn't as clear as it should have been, sorry about that.
I have found and added image of the carbon baffle.
Another int...

Thanks for sharing these images Serge.I would like to learn more about the Audiotekne bass solution.What size driver is that, is it a sealed cabinet, what is the baffle,and what frequency range is demanded from this box?Ho...

It was not a “heart”
but pure stupidity and my underestimation my Chinese builder. I decided to make
it back mounted and naturally requested to make some bevel over the driver
whole. I did not even care about the size of the baffle and I decided t...

[quote user="Romy the Cat"]fiogf49gjkf0dWell, that is kind of the end of the little midbass era. As
we begin to prepare the moving in a month I removed the Vitavox driver from
Midbass horns. The even went unnoticed in my family but I have a lot in ...

Yep, thanks.
I still do not know why you feel that I will not exploit the “ringy dustcaps” on the Malaysian bass drivers; in fact I never gave up on this idea. I preliminary concluded that my MF channel might not go lower then 700Hz but I did not sa...

Thanks, LBJ, I ma slowly getting into where I would to be in term of understanding, at least it is what I think I do. You are perfectly identified what I am shooting for: "its not a musical instrument but it won't piss me off", it is exactly what I w...

Hi Romy and thanks a lot for the always interesting topics and discussions going on... I'm quite new to DPoLS and consider the approach of "obtaining sound in a room" more than "speakers positioning" - too often to WAF fullfillment and aesthetics, th...

[quote user="Romy the Cat"]This is all because you are a primitive person with very simplistic and amateurish understanding of many things. You need to learn from much more sophisticated people, of cause I mean myself. Take a look: I do not run like...

I did put some gasketing under the driver, not thought but to so what it will do. I used the substance that I described above. It is Home Depot 3207680110 or the model #DS110 Pug duct seal by GB Electrical. The best thing about it that it is that pla...

Hi Roman et al!Allow me to introduce myself. I have followed with amusement Romy the Cat for many years. He is ascerbic and ultracritical, but he does know audio. We share many tastes, like the Koetsu Onyx Platinum foir instance, on...

[quote user="NBC"] 1) What dimensions for 1808 baffle would you suggest? [/quote]
It would be easy to circulate from the resonance frequency of the driver. The 1808 marked at 24Hz but in practice it could be anything from 23 to 29Hz. Since you...

Today I had a promising experience. Bill is keep experimenting with his Dannoys and I was visiting him to see what's going on there, since I am still waiting for my panels and I can experience the Dannoy foreplay only valceruasly. We did a very usefu...

[quote user="rowuk"]
Impossible. A passive radiator can NOT change its tuning frequency on the fly. It is a Helmholz resonator - one single tuning frequency. It is also NEVER in phase, it is always late as it takes several cycles to ...

Thanks, Josh. I looked for it and found a good link that accumulates a lot of recourses about Danley DTS-10.

Romy If you would thank about what you are building and what it does, you would grasp the concept of my thanking. You have a 7inch hole on your bafflle with your woofer on the back side of it in a sealed box. The only...

Romy,
No, the DAC was not set at maximum level (for best sound) while Cyrille listening to the system. It was set at normal volume for the whole system. When Cyrille dropped by, I was showing him the Field Coil open baffle speaker system which con...

Let start from far away…. Sometime in the past, while I was fighting with bad electricity, I was trying a variety of symmetric transformers. I do not know if they were implemented as good as they should (I doubt) but I detected an interesting common ...

Romy,Regarding your first illustration:Some time ago I intentionally made two different boxes for my ScanSpeak drivers to see what will happen, because I do not believe in theories and trust only to my ears. The boxes had exactly the same internal vo...

Carbon is used by Audiotekne in a variety of products, from vinyl claps to a speaker with a 35mm carbon front baffle.
Some guys in Italy compared the same housing configuration built in wood using the same driver and they swear it's so much better b...

In one idealistic configuration I envisaged for myself, for a situation where cost and practicality no object, the basic room shape was pentagonal, with the facets ot the pentagon curved inwards to eliminate parallel reflecting surfaces and simultane...

Hi Romy,I have found that the Apogee loudspeakers ribbon drivers can quite successfully reproduce correct tone. The reason why is this: They have very little coloration from the driver materials themselves (no nasty resonances as the reso...

So first in line, the horns. They stressed out that particularly the horn flares where not within the comfort zone of their own developer team.That triggered the recruitment of Bruce Edgar. The design is only his, and they took it 1:1. Of course too...

This is very interesting question. I do not know a lot of people with whom I might collaborate it as very few run ULF channels. Most of time people run just bass channels. It is my experience that whenever audio people talk or think about the low...
