After much listening and measuring I convinced myself that there is no way for me to escape the use of the 24dB per octave slope if I want to keep the sound of my midbass horn not violated. I also have to admit that I will not be able to render 4th ...

[quote user="MINGSU"]Here is an example on how to use GOTO 505TT driver. Use the GOTO S150 horn and crossover at 200Hz to 1kHz. If you like to use other type of horn and crossover point, you are on your own. Maybe good or maybe not but that is you...

[quote user="MINGSU"] SG505TT + S150 horn crossover at 180 Hz is not recommended by GOTO. The SG505TT driver is not recommended to use with single throat S150 horn. Double SG505TT driver is recommended to use with single...

[quote user="noviygera"] I think clearing this up this may be of benefit to other users who are building multi-way horns.Let's say I've got two horns mounted on a frame. There's a high horn above and a mid horn below and they are physically time alig...

I think most of reader get my point of the car examples. The main point is to follow the manufacture recommendation on how to use the driver. Of course, if you want to do something different, that is your choice but don't come back and blame the dr...

Operating a driver in an open baffle will cause front-to-back sound wave cancellation, aka the acoustical short circuit. In addition to this, a plane board baffle offers zero air load to the drivers cone. This is not good. That's why it sounded like ...

IMO A 60Hz attempt is too low and a 120Hz attempt too high. This is a difficult task, that of properly integrating horn loaded mid-bass withD.R subs.What type and slope crossover are you using ?I'm hoping you are going active here ?How much air can ...

[quote user="MINGSU"]GOTO always recommend to use 1st order active crossover and 2nd order passive crossover. The reason to use 2nd order for passive crossover is to protect the driver. Of course, the user can use whatever they like the best but the ...

Romy!Put on an engineer hat!
Time-aligned is an impossible task from my point of view. How can one perfectly time align different drivers? Align to what precision? mm, inch, cm or ft? 5%, 10%, 30% time align? Align to the tip of the cone or...

Jorge,
You're right about using identical amps. No doubt.
I have not used Dr. Edgar's passive network but I have tried conventional passive networks on Edgarhorns. They worked alright.
And I have...

user="Jorge"]We only
use the Beringher for bass under 100 hz, driven by the main amp. We tried a lot of different
solutions, including analog active xovers, the DCX is clearly better than the
Analog Xovers we tried. There
are very few com...

My five cents, folks... find nothing wrong in a flexible ULF, as it, sort-of, makes honour to any audio system and music and audio lover, as this "flexibility" strongly reminds me to various music and concert halls and venues around, where their "per...

Gentlemen:I've thought about this mid-bass challenge for quite some time. I have tried many approaches.For the sake of my example, let's assume mid-bass to cover from 60-600Hz. That just happens to be the classic "decade". I have to fully agree with ...

[quote user="Kerry Brown"]I don't understand when you say active crossovers don't attenuate. Mine does. Very well too, I can trim channels to match each other perfectly. And DEQX volume control is 'analog' = step ladder resistors. [/quote] I am not...

I've only had the pleasure of listening to 'professional' horns (whatever 'professional' really stands for)--horn normally used in concerts and small venues. (It was always so obvious to me--by listening--that the range of the horn-loaded 'bass...

[quote user="Tax"]The other options are to get some custom Amorphous OPT's <50R 350mA 8:1 as per previous posts, or to possibly pair Romy's LF tributes (for sale section) with a pair of Lundahl's in a two channel DSET configuration. The Avantgarde...

Last week found that the distortion I was having was due to some small separations of the woofer cone from the surround suspension probably from age and playing too loud. Applied the glue to them received from English tannoy dealer and distortion...

The crossover is built and will be testing it for the rest
few days. I am sure it will do some “comforting” for my SS amp. The question I
have no answer for myself if I need to use an input active stage. My preamp,
having 8R output impedance can p...

I am really not an expert in digital crossovers. I rented in past a few, inducing the Behringer DCX2496 that Thorsten mentioned. I less was concern at that time about the unit as prototyping crossover but rather was trying to learn if the digital cro...

[quote user="Reno"] ok. maybe we have a different understanding of "electronic equalization". We do not use active (i.e. electronic) equalization in the amplification chain. There is of course some equalization in the passive crossover but I real...

I spoke this morning with Yoshi and he made a phenomenal comment. He was complaining something about his bass. He uses a pair of big 15’ JBL in a box with an active second order crossover. So, when I asked him to describe what he feels is wrong Yoshi...

Markus,
If it is your task to stay with a single amp then all bids about line-level crossover are off. I would like to stress that although there are zillion theoretical and applied reasons to prefer line-level but still it does not mean that regula...

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...
