Aura made their 1808 driver in 80s and most of the 90s and it was wonderful. It had huge high-temperature neodymium magnet, unique magnet geometry with underhung 4" edgewound aluminum voice coil. It was the only 18-inch...

Thanks for your further thoughts and explanations Robert, Romy and others.It looks like the full room enlargement will be my choise. Dont know i want to block the windows though. Maybe i can solve this by making a glass window behind the screen.. I w...

I am using sealed bass arrays of 3 per side. I have six 10" scanspeak woofers in total. I aim to operate them from 38hz to 160hz with qtc 0.707I also have a tapped horn that I am using with my current horn system. It is 244cm's high and 125kg's compl...

I wonder whether an Altec 416 in a sealed enclosure plus transconductance amplifier would be the better solution for most people/circumstances....

Yes, for practical reasons, one side of an IB driver is usually "wrapped and sealed" to deliver lower frequencies from the other side, since it is generally impractical to actually make a baffle large enough to prevent sonic shorts. However, at high...

Actually it is very interesting question and I almost feel you pain for decision you will be making. I do not think that anyone would be able to express any arbitral opinion about the subject, as least an opinion that worth to follow. You see, buildi...

I agree that the right 15" is a nice size for mid-upper bass. I suppose yours are the 15" Vitavoxes that were made to go in boxes? Of course, the usual reason for ports is to "extend" LF, and most modern LF drivers are used in something like this, ...

For the sake of helpfullness, I think that we may separate the differences of the ported speaker designs of myself and Petar. What I have described is the standard, pedistrian model of a vented speaker. Petar's is a hybrid aperiodic-...

If LF are sealed, I would suspect that the strong SS/hybrid would be better able to keep the drivers "off the air cushion". When the drivers get to that point I hear something I would describe like this: Take your fingernail and...

[quote user="Joe Roberts"]The Western Electric L-9 in Munich was/is an infinite baffle design. The 754B woofers are in a sealed enclosure with a front horn. There is no possibility of cancellation between front wave and back wave of speaker, so I wou...

[quote user="de charlus"]It is indeed an interesting subject; I am instinctively drawn to it due to the fact that the majority of orchestral instruments - the majority of my listening is orchestral/chamber/classical soloists - produce their own sound...

Romy, at some point you did mention lowering current and shortly thereafter, if not in the same post, you added something to the effect of raising voltage. You even mentioned values you have tried, and I printed it out. But since I am usu...

It is not the thread to talk about Tapped Horn but listening to what you Tapped Horn users saying I do understand my suspicions about the concept. I can’t objectively judge sound from Tapped Horn as I did not hear any properly made, calibrated and in...

I needed 20Hz - 50 Hz in a large 7 meter x 6 meter x 15 meter room, and I wanted a sealed design. I have wine barrels laying around and fortunately the internal 4 cu ft of a wine barrel is perfect for 2 x 15 inch woofers in a sealed system. The barre...

Hi Cat,The more and more I listen to reproduced music, the more I realize dynamics and tonal respect are key to start any reasonable installation. This kind of crosses over into some driver discussions so bear with me...My Tannoy 10" ...

Actually a Tapped Horn would be bigger than a sealed enclosure, here is one of my first TH tests. The sound is very different than the sound coming form a Sealed encolsure. My first impression was that the bass was gone! There was no bass sensati...

Hi Greg,linkSearch the site and you'll find that Ulf has created a upper bass horn using the aforementioned TAD 1201's.I also own a pair still in boxes waiting for the weather to warm up enough for me to start some enclosures and horns for.My origina...

Hi,I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

In the linked there above “Barn Conversion - James' Project” I have expressed my attitude toward low frequency bass. I certainly not “against” bass horn it but have “concerns”. The “open bottom” concept that I invented for myself is always make me to...
