[quote user="coops"]I would never presume to make such a claim, regarding active bass,I have heard quite a few systems now where the ( active )bass is very disjointed, Avantgardes for example, and the music just does not flow, but I will discuss your...

I've been thinking abut this question form several angles. Firstly practical.I thought I'd better see what low bass sounds like. And to get some idea of placement possibilities. So I set up my LS3/5as in the (rather cold) un-converted barn. Couldn't ...

What is sitting on floor inside of left bass radaitor? Looks like two bullet tweeters? I assume he is just putting them there for storage as there is nothing inside right channel.He must be getting a lot of sound out of the back of those woofers righ...

Actually if that horn would not be bending atop, go for another couple feet vertically, consequentially has a smaller throat and of course has a strong back chamber then it would be a very good J-horn (presumably that the walls and joints are not res...

I visitor of my site shat me an email informing that that above depicted horn installation by Marc Henri and Andre Klein was made French Musique-Concrete company. I do not know a lot about those people, beside that they hand around Jean Michel Le Clé...

Can I have some opinions on a potential mid-bass driver for my Altec 515s, as pictured in the attachement? What are the obvious or potential problems I should address?see attached photo: 120 Hz - @800 Hz.For the Altec 515 such a horn should be ...

Well, congratulations, Jessie, and welcome back to the Surreal World!For a while there your posts were reading like a dime novel!I hope you will try the doubled ML2s to see if you also hear the unusual effect the ML2 has on bass.What I get is th...

I've been thinking; rather than placing the mid-bass horns off to the sides or above the rest of the horns as in the first two images below (a CAD model of the horns in my new place); a plan which implies accepting imperfect time alignment...Ori...

I've continued thinking about construction since posting my previous laser-cut hallucination (titled "Painless mid-bass horn"...). Thinking mostly about the transition from round driver to rectangular horn... I don't know how...

Hi Keith,That is an interesting way of setup the S150 horn. Most of GOTO setup that I have seen set the S150 high and point down to listening position. All of them crossover the S150 + SG505TT at 200Hz to 1kHz range. I wish that I h...

I'm a new reader of your website and one subject which interests me a lot is that of upper bass horns.As you have noted time and again (with which I agree almost completely, after reading a lot of 'research' [many claiming to defy the laws of physics...

I built a pair of tapped horns, as per John Hasquin, designed to integrate w/ mid-bass horns (cross over ~ 70-80 hz). Loaded in the corners, the low bass is well supported, and, they "dissapear" sonicaly. By that, I mean, they don't "stick out" at ...

[quote user="Romy the Cat"] A few years back I wrote somewhere that I “developed” a semi-mathematical formula according to which an acoustic system’s result might be absolutely objectively weighed up. I did not go very far with advisement of this eq...

Consider a triode connected 13E1. 95W dissipation, will probably work beautifully with the existing OPT if you adjust the gap down and if you can rewire your arrays to present a somewhat higher impedance.Something like 400V-450V / 200mA-ish will ...

[quote user="KOTriode"]Romy, in the contrary, it is very unfair to compare my 845 amp with the 6C33C. The main reason is the 845 amp used the best output/interstage transformer available, while the 6C33C's output xformer is pretty good but far from b...

Hi Romy,So it is time to think about the bass output transformer in my DSET. My bass channel will be 8 x 25W/8565-00 each side set in a sealed box and will cover the frequency range below say 100Hz. These drivers can be wired anywhere between 1R an...
|
|
Well, it might sound as a heresy to you, but I personally
consider the impedance curve is a bit irrelevant in this application. In this application
you need to care only about only 2 things: if you have enough power in you LF
DSET to drive your li...

I heard far worse bass performance in a good number of other rooms at the show. If the intention was to give people an experience of how large scale music/sound reproduction was or could have been 70 or 80 years ago, then the arrangement they chose w...

[quote user="Kerry Brown"] Yesterday a friend of mine brought over a CLIO analyzer and we graphed the impedance vs. frequency. I was surprised that the subhorn measures like a ported box tuned to 50 Hz ! [/quote]Yes, this all is very explainable. The...

[quote user="cv"]Romy, Can you expand a little more on what the issue with dipole bass is and what it does incorrectly? I'm still not sure I know exactly what you mean (and I've had a look at some of your other comments on the site).[/quote]Chris,

Jessie,
Perhaps if you search something in the throat jungle you might fish some interesting results. You see, optimizing the driver to throat transition you might get some HF out of upper bass driver. But besides getting more HF there is something ...

.... available bass horns are the same to me and I customary discard them. I also care less about the price: I am talking about an interesting horn design but not about an interesting product to buy. The beryllium cones - yes I do not like them in TA...

Actually it is very interesting question and I almost feel you pain for decision you will be making. I do not think that anyone would be able to express any arbitral opinion about the subject, as least an opinion that worth to follow. You see, buildi...

I have the CD but didn't get a chance to listen to the B9 effects you mentioned yet, but all the 515Bs and 15" Vitavox I have heard were in larger vented boxes. I think of the dryness you told of as part of pushing a paper driver down in a sealed box...

[quote user="ml8"] If you think gas regulators make sound of 6E5P so nice, didn't you try putting gas regulator tube in the grid of the 6C33C, and why? [/quote]
