The full-rage single-driver acoustic systems is probably the most hated playback topology by me. It is irrelevant if you use $200 Fostex or you use a family reserved edition of AER driver for $64.000. The result you have the same: a horrible dynamic ...

Ok, let dive a little bit further into my examination of the subject of Lamm ML3
What is important is to undusted that my view less targets the Lamm ML3 but rather it targets the ML3 as a representative of entire class of amplifiers. When I to...

[quote user="oxric"] As to why people are interested in the 16 ohms drivers, that is only true of some. The idea is that if the Vitavox S2s are being used, and a single amplifier to drive the different channels, it seems to make sense to go for 1...

Romy:I was not aware that manufacturers of multidriver system let you attenuate individual drivers. I guess if you multi-amp, then you have control at that level. I have never encountered such a system so I cannot say, but if it is an option, then ye...

[quote user="HookEm"]I've heard so much about these legendary SET mono-blocks; but as I understand it, it's VERY important to match them up with proper (efficient) speakers.Anyway, I'd welcome some feedback on matching these amps with Lamhorn 1.8's +...

Maybe no other hi-fi group has thought more about the cabinet's contribution to sound than the single-driver crowd. Many of them like the "immediacy", "integrity" and "purity" of the single driver sound so much that they endlessly hu...

[quote user="floobydust"] The main component that limits low-frequency response in any SET is the OPT. For these initial designs, I used the smallest Hashimoto SE OPTs... their H-203S for the 2A3 and their H-507S for the 45 which are rated at 7...

I am NOT talking about single wideband drivers or any back loaded type horns. I am talking about properly made front loaded horns.
For example, the Danley Synergy horns, that use single horn with multiple drivers to cover a wide band...

I can see objections to using paralleled tubes to achieve higher power where the channel has a single driver, but surely where you have multiple drivers differences between the drivers themselves would render any disadvantage of using (say) one tube ...

Maybe what we need is five channels to cover all the octave and two or maybe three drivers for each channels. You could then tune the contribution from each driver to get the correct tone for each channel. The only drawback is that it would require m...

Yes, heard Kevin’s installation with large subs. I did have S5 driver in past, it was a single driver and I did not use it in my system but rather experimented with it. I was not too impressed but it was long time and it was during my people when I w...

I can understand wanting to reach out to audio people everywhere, but think that this speaker is a joke for many of us here. It certainly has nothing to do with advanced audio or evolved music reproduction. Even on a DIY site, how much traction does ...

[quote user="Joe Roberts"]I thought I was quite clear about my evaluation program: Put it on. Play some music. Does it present a compelling emotional experience of musical enjoyment for me? If yes...GOOD! If no, maybe somebody else will like it. This...

Would it not be possible to create a type of transmissionline, but with a closed port and many bends to spread the internal resonances and provide means to damp them.Perhaps it is even good to tune an open transmissionline to a couple of octaves belo...

[quote user="Romy the Cat"]...to hear it from a person who advocates a single driver approach :-)[/quote]
Hahhaha, if
you call the combination of 4x23” + 4x15” + 12”+ 8” +2” a single driver
approach, then the people who really use single driver sp...

John, I have to confess that I feel very not easy about the idea of Synergy horn. I did not hear the Danley Synergy horns and I have very superficial understanding of what he is trying to do with the whole Synergy/Unity idea. The whole idea does ...

[quote user="rowuk"]Brass instruments function much differently than audio horns. First of all they are built extremely resonant by mismatching length and horn taper. The taper of the bell is there not for horn type efficiency, rather to change the a...

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="rowuk"]Hi Amir,your english is just fine.I think that there is an additional factor that your formula needs. Sense of pitch is not determined acoustically by "Q" unless we are talking about pure sine waves. When we add the overtones foun...

So, I have finally started testing a single Bass Cannon in my room.First, I had to get the rigidity as high as possible and then damp the steel ringing as much as feasible. I used butyl rubber/aluminium automotive deadener on the inside of the tube ...

Well, I see where this dialog is going and what the essence of the dialog is all about. I think it is the point where the sings are comprehensible -enough, at least on the subject of the Silbatone Acoustics new speakers. I told or implyed everything ...

The things I like best about a good wide-range drivers are coherence and immediacy; like nothing else I know of.But awareness of the limited range (certainly not FR), dynamics (certainly not natural on most music) and any res...

[quote user="haralanov"]Ironically or not, I have no practical problems with it, simply because I’m not using big UB horns. My upper bass channels are much more compact – 4 very massive 15” drivers with no horns. Their integration to my main widerang...

Ok, since you people stop to drop the euphoric saliva around the Goto subject I think it would be worth to outline my interest in Goto. Not only worth but I kind of feel an obligation. I feel that my site surprisingly has become a resource that ...

The quality of microphones is irrelevant and if you use not 1/3 octave sweep but Noise Generators then you need to run time average on your RTA. Time average analyzers is fine but it need some additional experience to interpret the results. I do...
