Righto then, I guess there is no reason not to try this, except that one of the original crossovers here is non-functioning (if I remember correctly), so if trialling in stereo I'll have to crossover in Melquiades. Should have the parts here to do t...

[quote user="speedysteve"]The systems I've heard with steep slopes (only 4th or 8th order) sound hard and unnatural to me.[/quote] Yes, the higher order crossovers do sound harder even if all time alignment measures are taken. Still, do not forget th...

[quote user="rowuk"] Need of Time alignment, in my opinion is an "acquired" taste like
with cigars, good wine or cognac. It is the product of an investment in time,
purpose and result. [/quote]

Putting together a speaker system that ticks all your boxes is a lot like doing anything else well: it is fine to experiment in order to find your range and learn your options but once you choose a path you must stick to it. Chopping and changing i...

Well, it looks I’m near finding a more or less acceptable setting for the T350 tweeter. Ironically and completely accidentally it is not far form I use to be. It is still on the slope at 20Hz (since the T350 is pretty dead at 16kHz) but now it is &nb...

Stephano Two good ears has put a post on his site about his new 4 way passive xover.I think this is a better direction than the digital xo. The designer, Thomas, designed also the preamp and I guess he has taken into consideration the input and ...

[quote user="drdna"]I was really shocked when I saw this idea of yours. It is a trade off of course with improved control over narrower frequncy bands being traded for axial symmetry. Yet because the position of the drivers is so very imp...

Hello again, Romy...
I totally agree with you about changing the rear chamber volume. It makes a very positive improvement in extension as well as quality. Also, I had never dreamed of a driver with a variable compliance resulting in a variable...

A friend of my after reading my comments about the EdgarHorn installation in Vegas (in here) asked me why do I think the bass in Bruce’s room behave as it behaved. I tried to think about it. Some of those thoughts intersect with some other projects t...

Well, acg, I am not wild about your idea of the curved frame,
primary on the reason of esthetics but it is your speaker not mine and you
shall do whatever pleases you. A few mandatory things that I would like to

Will try to answer all questions here.Romy: I understand why you do not wish to use the term “surround sound”, but it is the accepted term for what we are discussing. You may add other terminology, but it only muddies the debate until others accept i...

I guess you cannot say you listened to a horn system if you dont have an upper bass horn.The upper bass horn has to fill in the response from the compression driver down. At this delicate range nothing will perfectly macth it but another front horn. ...

I don't have RF sweep generator but it's fairly easy to source here. I will take the tuner to local FM tuner tech to re-check alignment and we'll take it from there in a couple of weeks. I will have to read more about RF circuits trough this tim...

Sounds Very interesting, If you can change the loose insulation in there for Cellulose, it is supposedly much better sound wise than fiberglass. It would also help to avoid leakage of bass to other parts of the house through the attic, if that is p...

Gee, now that I read my post again after yours.... that last bit didn't quite say what I was wanting to say (I hate when that happens). I was really referring to people being "brand specific" as my example of the 45 showed that you can't always...

i see the words time alignment quiet often in this forum :)Which is a good thing. But can you show a graph / measure that says what it means in a result?Or do you just mean the woofer is standing next to the mains?Cheers Josh ...

Tweeters Alignment - what is a bitchy subject! I was mildly complaining about it for years and during the last few weeks I complain about my own tweeters - primary because the very same issues of the imperfect alignment. This there is a derivation of...

I have been doing some work with integration of tapped horns. I have discovered some interesting things that are not being discussed on any other forums. I’ll start at the beginning so a full picture will be clear. At first I placed the tapped ho...

Ah, Texas, they are truly helpless people. They did not reach the level of humans evolution when such a fine things as bass time alignment would matter. They need to experience an influence of the Renaissance first.... Seriously, a nice looking list...

I helped Romy shuffle around some hardware and connect some cables yesterday. That damned table weighs about 100.000 pounds. This was one of those once-in-a-lifetime opportunities to see live, in-person how Romy thinks about audio and incorporates th...

Ok, none it is time to dive into the practical process of tweeters alignment. Once again I presume that we are taking about monopole tweeters that use AFTER your midranges compression drivers (read my previous post). Some people use term “supertweete...

Great analyses, David, thanks. I can’t concur as now with anything. Macondo in the room with midbass horn was a complex installation and with ULF it became even more complex. Some of the things I setup by ear and do not use measurements, I just know ...

http://hifiknights.com/reviews/speakers/rdacoustic-evolution/I think that David should search here about full range speakers. As he obviously can't hear the difference, maybe reading about it will help improve his designs.David, just for your informa...

Number one, that I'd like to run by you guys due to it's simpler nature and closer to reality execution is the idea I have been thinking about. No first hand experience with any of this.Say we use something like altec 1505b multicellular horn that sh...

Now I have been listening the different crossovers trying to shape the new Macondo general balance. This is so fascinating ceremony that I do have a lot of fan. The things doing alone very well. I boosted upper bass and it worked now very-very well....
