I put the Super Milq and the new one-stage Milq today and was playing them together in order to see which would be more interesting. It is imposable to “compare” as is the upper bass and lover mid channels as the Super Milq has all kind of line...

[quote user="drdna"] So, my thought was that below 35 hz, there are many ways of thinking about amplification. Some might say SS amplification is helpful due to power demands of horn loaded 18" woofers. To use 6C33 might be a trade off but I do not k...

This is the project that I been thinking to undertake for years. I have motioned about in multiple times that Vitavox’s S2 lower region is very lucrative but unfortunately not exactly useable if the driver run all the way up, unless you are wiling to...

Rich,
I think it’s too early to seriously to talk about sound of your driver. As I understand you have no horn for this thing. Your comment that the driver goes all the way unto 8kHz clearly indicates that you used wrong horn before. If you stick a...

Continuing in my quest to the finding the new DPoLS with my Super Milq I did some “critical test listing” today. I’m certainly getting closer. I spent a few hours to play with the playback and I recognize that the first signs of the approximation of ...

[quote user="Romy the Cat"]If I succeed to make my midbass horn at attic then I will face another problem that I do not know how to address at this point. The horns will be powered from Melquiades bass channels – it means it will use a good 70 feet s...

This week I will be trying to address why the Milq midbass is clipping. This is very interesting one. Currently the Melquiades LF channel uses an output transformer 700R to 5R or 11.83 to 1. I thought before that I have much lower ratio, like 5:1 bu...

Here is a good illustration for people who do not get it why La-profile is suck a damn idea with lower then MF channels. There is a guy in AU who makes the La-profile horns from some kind of plasmas and sell horns separately, not organized into c...

Hello Malinowski,
Sounds like you may already have the necessary experience in working with plaster, but in case you're not used to making anything this large:
For the final horns, especially if they are large, use hard modeling plaster. My up...

As I said above your you "experienced today with GOTO" is just your transitional
feeling and you will change this feeling many times. To accommodate a pair of 42Hz
horn in a system is a year-long project otherwise you get an accidental result.

[quote user="martinshorn"]The bass horn for the ak151 is housing a rear chamber slightly open, giving the injector channel - that creates a lot charme, flavor and „heart“ but also 3 dimensional projection. [/quote]I need to say that that very muc...

A friend stopped by tonight when I was test-listening my midbass horn. He got freaked out from the size of the thing. I played for him some Gerhard Oppelt’s organ recordings. He told me that I am crazy, like I do not know it myself. Anyhow, he made a...

One of the challenges I see for my midbass horns is to minimize hf output. The goal is to operate the horn in a bandwidth where it can cross to the higher horns, and have each horn function in their best sounding manner. My drivers are Altec 515-16...

[quote user="Dresden"] I've concluded that building at least two--and perhaps three--different versions of a Mid/Upper bass horn design will be required to determine which of the three configurations perform best. [/quote]

[quote user="Paul S"] The best hi-fi LF I have heard came from modified "pro" units (multi-15s) that had a LOT of power thrown at them; and furthermore, the system was "managed" by an... equalizer (albeit, done in real time...). [/quote]

Robert, what I meant is following: when you will be collecting requirements for you own drivers specification and will evaluate the implementation methods then you need to have you own identity what you are trying to do. I might post a lot of differe...

Anthony, yes, it is a perfectly legitimate question and I asked
myself this question many times. I do think that if you make horn from wood
then heat will damage them but if your upper bass horn is from concrete (like Jessy did) then it does open ...

And email from a site’s visitor:….

Ronnie,
Very nice, though I do not know where you would like me to move the thread. (It looks like it’s OK where it is). There are some comments that I might to pass.
You decided to go for a large MF driver. This is fine if you like it but I ...
