Looking at Vox as a glorified 2-way Altec speaker with tweeter and supertwiter with all " not optimal" choices ,folded 70's PA thunderbolt mid bass cab time misaligned crap ( Romy's opinion ) bi-radial Vitavox midrange suitable for derby races and d...

[quote user="Jorge"]I have seen Beyma rewrite their specs when they redo a driver and even add a letter to the driver for that change, even if it is the same driver.Now I have seen variable FS responses form different drivers of the same model also....

[quote user="Jorge"]One more thing about the JBL 375, I did play around with them enough, I aligned the diaphragms several times untill they sounded their best and were very listenable, This was some time ago now, I didnt turn my horns then, so I tr...

Of course I am not really talking about Rullit but only holding up his implimentations against his stated aims. This is certainly no special case, since most smart people learn the talk and the "look" long before they learn practicum, if they ever d...

Surely one of the objectives of this site is to allow people to be guided towards good sound by discussing the issues involved in getting there. Whether that entails discussing the merits of different recordings or performances or whether it entails ...

So, two almost two years later and this contraption is still in my room and "ain´t goin nowhere" :-)Guys, I became obsessed with horn speakers and specially with Onkyo product so I would like to share with you my latest experiences.The speakers I tal...

[quote user="morricab"] I have found that the Apogee loudspeakers ribbon drivers can quite successfully reproduce correct tone. The reason why is this: They have very little coloration from the driver materials themselves (no nasty resona...

Hi Jorge,If $18,600 is the price of your 4-way horn system, even without knowing more about the sound and the choice of drivers, I think it is an amazing bargain by anybody's standards in the current high-end audio landscape. I hope you are inundated...

Hi, yes i agree that my solid-state amplifiers were not best choice for compressio drivers, they were my second amps when electricity was bad, otherwise I use a custom made 300B from La maison de l'audiophile for my system when electricity is v...

Wojtek, I am indeed hemmed in by the fricking electricity these days, to the extent that it is about impossible to hold on to a baseline for reference. And the Lowthers only make the problem more apparent.Yes, I still wonder about how I wo...

Mike Hi, prices and value well the new Gamut speaker was next door to us in Munich, Euros 95K it was unbelievably poor , Avantgarde charge how much for their large Trios yet the modified conventional drivers they use cost only a few bucks each, as to...
|
|
Not that it matters, but I can't remember if that speaker was originally ported or really "sealed". Some of the old drivers were actually put in "tuned boxes", for better or for worse. I understand that your objectives for this driver afford you a ...

My room, is 16 to 17 feet wide, 27 to 28 feet long by 12 to 14 feet high with all walls splayed, with a combination of absorption and diffusion on the walls. All electronics are fed electricity by three pure power units originally recommended by Rom...

Yes, the way you came up with the Dunnoy is FUNNY! But I will tell you now that I was thinking of the 10" Tannoy for the reverb channels, not because it "does everything well", but because it is acceptable in terms of scale, and it has tone, and it m...

To follow up on Romy's latest broadcast on his visit to my house.My left and right speakers consist of Jl Audio 113 revision 2 subs to 70 Hz., Edgar 50 Hz. 6 foot Straight horns with two 12 inch electravoice drivers each to 500 Hz, Edgar round mid ho...

Well, there are standing waves, and there's SPL, on and on, and there are plenty of good arguments against any implementation. Not many drivers today that would be a fit for IB, which might include ways to damp s.w. resonance, such as interior "curta...

Curious to know if this guy nails just the pitch, timbre and attack, or maybe it also does dynamics?I have run across a few car speakers that are simply astounding in a narrow range, provided the going does not get too tough.Bob Fulton (RIP) found on...
|
|
Big 93 dB woofers with a "split" no-feedback SET?Perhaps if you re-think the LF drivers you might indeed start with a vanilla version/pair of the Melquiades, just to get a sense of what you're dealing with. If you are able to get or get a sense...

John Hasquin showed up a couple days ago and suggested that many of modern compression driver manufacturers design thier products to get the "best" publishable parameters while completely disregarding any basic horn design rules and actual sound resu...

[quote user="el`Ol"]But when the frequency where the dipole acoustic short circuit "kicks in" is clearly below the Fs of the driver, everything "dipoly" that can happen are rear wall reflections with the wrong phase, and that danger is also reduced b...

I am not "working backwards" from a tweeter. I presently use Harbeth M40.1s, but having recently heard the Living Voice Vox Olympian and an Audio Tekne horn implementation of Ale Acoustics drivers, the experiences opened up new vistas of what is poss...
|
|
Hm,… yes and no. Inductance is not necessary an evil. Well, it is an evil for open-top-end drivers but you need to look at the life of compression driver all around and then you understand that inductance is not limiting evil. Sure with grow of diame...

Those who publicly hate you the most will line up to buy the house the same way they buy Lamm amps with plastic speaker postsand Vitavox drivers , don't forget to leave the antenna mast and as many artifacts as you can ,down to Koshka poop, heheheMa...

I think it best you speak to Ralph directly ,he works with these drivers every day.I do recollect that inthe case of the Supravox ,where there are permanent and field coil versions of the same driver,Ralph told me that there wasn't a huge difference ...

Here's something from a guy perhaps better known for his direct radiators:http://cgi.ebay.com/Atelier-Rullit-RH-T903-field-coil-drivers-/330581513356?pt=Vintage_Electronics_R2&hash=item4cf831948cBest regards,Paul...

user="martinshorn"] What Klaus also highlighted, is the importance to
him to unlimit dynamics - in order to achieve the most live-alike sound. First
of all, he noticed that Goto pleases him the most with uncompressed transient
attacks more...

Hi Romy, i used S2 for about last ten years and recently gave up on them, i don't have the skills to get the soundI want out of them. They were giving me lots of string bite, but not the fat wood sound, they were closer with old multicell horns tha...

Robin, I guess I got off on the wrong foot when I phrased the first paragraph as I did. I meant to agree with Herman about "dissimilar" drivers, but I also meant to continue thereafter with other thoughts on the initial topic, musical vs. audio pitc...
|
|
Another thing to consider here is a specific reason or reasons to use the "PR Type" Scanspeaks as subs, since Romy says outright that the Dannoy's PR cones have "no ouput", but the (rather amemic) LF from the Dannoy'ed Tannoy is all there is from the...

Nice to see someone actually try it. I know that fast rates "work" from MF and up; but I have not tried it with compression drivers/high gain/LF.Thanks for sharing.Best regards,Paul S...
