I made the move toward to what I think might be done with Injection Channel for my Macondo. In the picture below is a new home for the 10-incher Red. The box is done interestingly. The front baffle is 1” MDF all the rest is 3/4n if a regular cheap pl...

Ok, the Injection Channel project is over. I dumped the boxes not heavily and very conventionally, painted them, installed the drivers and crossovers. Sure, before I put the injection channels into the Macondo frame I flipped them upside down and tri...

I was slowing mingling the conversion of the power supplied of my second Super Milq from 3 channels into 6 channels and I ask myself: is anything in that amp is made in the way that would allow me to close it up and never review it. Sure if I move in...

I was kind of frustrated with some strange high frequency roll off at my HF and Injection channels. It should not happen. The 9H OPT LL1627 in Injection channels should be good up to 23kHz according to my former tests with a full range Milq and the T...

There is a lot that is not there yet. There is no injection channel; there are no 2-drivers extension for
bass towers. I am progressing slower than before: 3 kids under 2, so it is kind
of hard. The injection channel will be
in a new enclosure, th...

After thinking about this for a while, I have had a thought that should be relatively easy for anyone motivated to explore and I would be interested to see what others on this forum observe from such experiments.Fundamentally I think the injection ch...

[quote user="drdna"] Fundamentally I think the injection channel and layered sound are different things. The injection channel is designed simply to compensate for the timbral shortcomings of a particular driver. However, because of lobin...

On this Saturday Boston Baroque performed in Jordan Hall Beethoven’s Symphony No.9. Boston Baroque is a very interesting group. It was a small perhaps 20 people chorus with truly phenomenal singer and it was a spectacular period-instrument band. You...

As I am slowly put Macondo back to the business a question come to my heard: how can I make the Injection Channel sexier visibly? As now Macondo is re-assembled and reinstalled but with no Injection Channel sitting atop. I extend no room for argument...

[quote user="Rewind"]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. [/quote] OK, but it is not how I feel about the service of injection...

[quote user="Jorge"]I guess it would be simple enough to add a couple of inches in order to bring the throat down to 4" in order to try the Studio 8M. I have already reduced it temporarily to 3" in order to try the JBL 2490h compression driver. ...

Both UB Horn roll off circa 130Hz in room. There are a couple of rough MDF boxes here that I knocked up from spare sheet a while back. Have not tested them specifically at the intended spot behind me but running around with a microphone shows those...

I wrote about it before and I was/am afraid this effect too. I discovered it a few years back when suddenly my bass picked some odd harmonics. After a few days I realized that the harmonics came from an acoustic guitar that was sitting in my list...

el`Ol,
it is so obvious with simple listening where is right polarity that is you try it you would not have doubts where is “right” and where is “wrong”. It is very clearly where the Red works with Macondo and where they work against each othe...

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...

Well, never say never and what I said that the Injection Channel is done it meant that it WAS done. I am experimenting now with other way of use Red injection. The application as is at the picture practically had no impact to imaging. However, I need...

[quote user="jessie.dazzle"] Your latest post got me thinking in a sort of incomplete way about how you might locate the injection channel... If you consider tone as a harmonic of the original source, then (depending on the order of harmonic) it may ...

I put the YO186 back to the use. The sound was fine but it had that a fine over glow of spoiled fall colors that I described before. It was not disgusting, in fact pleasurable but a bit too much.
Then I asked to myself what happen and why this...

[quote user="jessie.dazzle"] Its still not perfect, and I had the mic 1m from the membrane of the driver (had not yet read Romy's last post where he recommends putting the mic back at listening point). [/quote]
