This weekend wife told me that I should not do nothing else
but to fix my playback and this was exactly what I wanted to do. Yesterday I took
good 14 hours to play with it, moving boxes, trying to find a good
configuration, making measurements, th...

I came within an inch of mentioning Gould in the first post but decided to leave it to Fischer, whose performances earn a dedicated post, especially as noted.Yes, there's no way around Gould in his high manic perfection. But too much of Ba...

It is hard to get used to the idea of 1 or 3 LF channels supporting a "stereo" hi-fi. But the way it winds up working is that the "wrong number" of channels, or sources in the "wrong spots" can make things sound worse, because of cancellation an...

Hello RomyI like Shelters as well, so I finally scrubbed-up enough money and began to search. I was always happy with 901, but there were none around. Last night I got a 90X, with (supposedly) around 100 hrs on it, within driving distance. So today I...

Romy,I say "Go for it"! With your usual documentation, we can only profit from you getting the hernia first. I got mine operated on last week, so looking is all that I can do for the next 3 months.One thing that has always roused my curiosity: your ...

I understand your recommendation and agree. I need to have upper bass and MF and than see how to merge fundamental channel in between.So, I better postpone experiments with compression drivers and only compare 12" Supravox in two horns: 42Hz 2m long ...

Gera, I have lived with similar for years, turned this problem all around many times. While something like 15" Tesla AROs should work well up to 250 Hz, I think you will have to get very clever to get more than flatulence or thumping below 40 Hz fr...

Yep, indeed, it looks very nice. The 8 sections of bass line
array look visually slightly overweening but I think when you put the upper
bass horns in place it will visually balance the things out. I feel some sort
of envy to the way how you plan ...

My minimal distance between front of the upper bass horn and listening position is irrelevant as I set the proximity not according the upperbass but according a vertical shifting of HF image. Under a normal circumstances I might be as liitle as ~7.5”...

[quote user="guy sergeant"]I meant the upper end of the LF horn response. Firing it downwards at the floor as they do and then expecting good performance at 200-300Hz in the listening position is a tall order. There may also be some confusion where ...

LOTs of time pretty much wasted lately, looking at "HE" direct-radiator drivers that are actually only HE at their uppermost frequencies, with diving responses and large-to-huge power "ratings" that allow the "pros" to simply turn up the heat to...

Checking if you playback can discriminate absolute polarity is very simple and very effective way to find out if you acoustic system is not fundamentally faulty. Flip the polarity and monitor the result. If you did not experience dramatic changes at ...

I think 8-8-1 will be very good configuration all together.
Make sure it stays sufficiently far from back wall. Point the axis toward to your shoulder and I think it would
be fine setting. Turn off tweeters and Fundamentals channel and set right

I have been enjoying the "Euroclassic Notturno" (BBC?) program on swedish radio tonight. As a happy rookie in the world of classical music, I seek advice on Tchaikovsky based on what I just heard; His Symphony No. 5.I thought: "Horrible waltz mi...

Here are some photos of Martin Sedon's 204Hz and 340Hz Le Cleac'h horns, which likely have more reasonable shipping charges and fit through doorways, etc. better than the 160Hz version. They have a T-factor (expansion rate) of T = 0.8, which was reco...

This subject of digital crossovers became quite popular during last few years and many audio-people give up and go for a simplicity and painlessness of digital crossovering. There is an army of people out there who would swear by a complete transpare...

[quote user="Kiom"]great project ! do you have a idea when it will be ready ?[/quote]Hello Kiom,I imagine getting the frames done and all but the 45Hz horns in place by September. Because of the mass involved, the Upper-Bass horns take FOR...

Jessie, there is another solution that you might consider, that might be viewed as compromise for one-side as might not be view is compromised from other side. If to allowed ourselves to close eyes to midbass timing-integration and if the geography o...

Hi Romy,
Well firstly on those, the tweeter is not offset to one side - it appears to be time aligned directly behind the midrange horn and upper bass unit. Secondly, that's a JBL 2405....

I have long wondered why it seems that hi-fi systems always fail to deliver realistic "weight", certainly with orchestral music, no matter how they "measure". A "flat" chart is a virtual guarantee of sound that ultimately lacks "...

[quote user="Jorge"]Andrew,Dont buy all the drivers at once, I would get only the upper bass horn drivers and maybe the mid drivers, you will have to play around with these for a while before things start clicking toghether, by then who knows, ma...

I'd like to point out that Fostex 500 MKII is very much not sharp and artificial sounding. If anything it's an opposite -little too syrupy , soft and round so it blends with cone mid better than beryllium tweeter. I have no first hand experience with...

Herman, I am glad that you feel better about sound from your midbass horns. I do not know what damage digital amps incur but even your experience of hating the sound of those horns to falling in love with them just after changing the amp do suggests ...

We now call those modeling lamps in our big stobes. I think that the analogy is even better considering your intentions.I personally feel strongly that high sensitivity is the correct path and that small ported woofers in a MTM box will fall short of...

I had this same experience listening to B&W 801 matrix speakers recently. These were very dynamic, more so than most speakers, and this stood out above all else. But these were not pleasant to listen to. I wanted to leave the room.These were made...

[quote user="jessie.dazzle"]Do I understand correctly: AG used Fane 8Ms in the Trios upper bass horn?[/quote] Oh, no! AG in Trio’s upperbass horn used similar 8” driver with 103 sensitivity. That driver was bad and it made me to look for a replacemen...

Ming, did you consider to hang your upper bass horn that screws everything up at the very top of the room and then nicely position the MF channels according to the rules of time alignment instead of the rules of warehouse storage? You might also cons...
