Hello Paul,If I were to come across such a thing, I would not say no to a little experiment with a driver that used a neodymium magnet.All drivers I've been trying lately use AlNiCo magnets... Compared to some of the other dr...

Hi Klaus,
Spec sheet on the bass driver you plan to use here: http://www.greatplainsaudio.com/downloads/515_G.pdf Just to be clear, mid bass to me means from 60Hz - 240Hz.
Throat diameter : 9.9 inches ?I'm just a beginner, ...

A six year ago or so when I played with different compression drivers I bought a pair of Dukane 5A540 and at that time I was not able to find any information about them. Nowadays I was pointed out that an eBay sealer “ bayleafs” actions a pair of Duk...

[quote user="el`Ol"] Hello Romy, have you searched for explainations for these observations? Are there others who made the same observations and tried to explain them? Does the damping factor play a role?From my limited experience I can say that ...

Let me list for you what I think drives sound quality to me:1. In room flat response at the listening positions2. equal decay at al lfrequencies off axis3. Adequate delay between direct & first order reflections. 4. Lack of distortion, or suitabl...

Paul, Points well taken. The F120A is listed as a FR driver. In my humble view, it does quite well for it's size, albeit the last two octaves will not be in full force (okay, the last octave is mostly MIA). It's lower sensitivity does not ...

Romy,If you use the plastic surround S2's from 500-5KHz won't you still have the bulge that concerned you at around 1.2K? I thought you suggested that the metal suspension units didn't have this bulge.Otherwise it seems a nice idea, albeit a bit expe...

hi Woitek. The K33 extend the bottom end by the high Q, to almost 40 cycles . Which is only ok if you work with passive XO on a single amp. Well that's how they were designed. Having designated amps that allow you to steer the parameter or even bett...

Here are some of my observations regarding the Wolf von Langa RCA 1428 replica. I long time wondered where mr. von Langa gets his phase correction elements and the diaphragm for his RCA 1428 replica. It's obvious that a niche-manufacturer such as W. ...

I am not a huge fun of S3 for MF use as the ceramic magnet is less interesting then alnico magnet for HF applications. For the low mid, or as I call it the Fundamental Channels the HF problem that ceramic has do not manifest themselves. My Fundamenta...

Gordan, I think you are missing the accent of what I meant to say. The Class A or not is not important for compression drivers and the S3 in particularly. I mean it is important and it much be ONLY class A but I do not see any SS amps switching in cl...

49Hz To 52Hz will be your peak, so the best you could hope for would be 3 hz below that flat with a perfect tuning of your length of your horn and back chamber of your box housing your woofers. If you shoot for the free air low res of your design, of...

[quote user="Bud"] I have a really barbaric suggestion... of course. I can set you up with 8 lLinaeum, soft, live horn, dipole tweeters. Stacking 4 per side should see you at 103 dB sensitivity and 8 ohms of impedence. You can stack them without inte...

[quote user="coops"]I have't heard the driver in the Beta, I am told that there isn't a great deal of difference sonically between the field coil and the alnico magnet versions of the driver. [/quote]

Good luck getting midrange from F120A for non annoying monitors. Seems reasonable to expect, many people have been very happy with these drivers... I haven't tried this specific driver, but have spent some time trying to get a simila...

KM, I don't know how you come up with the belief that I conclude that "it's a bad performing driver." Either the 138, or the earlier 120... Or that because I didn't use 120s that i haven't heard them. And as ever...

Hi Dominic,
I have some Rola's. Although intended (in organs etc) for quite widerange use I'm not sure that for listening to music they should be allowed to go too high. The other thing I found was that what lower frequencies they produced were more...

Unfortunately its $1000,- total... Its not fixed, i can still do alot with that though.Alnico is better but only available in vintage drivers right? How does neodymium compare?The Jbl's seem to fall off fairly quickly. I dont need flat to 20K b...

Well, it was not trick question; I thought initially that they were TADs. However, TAD uses Alnico7, Alnico 5 and Neodymium magnets not the cobalt magnet. The TADs drivers do not cost €4K but rather €1.5K. I never heard TAD use Samarium-Cobalt ...

Last time we wrote you thought I should focus less on tweeters and more on midbass.I am not done yet, but I have found a very nice midbass solution. Somewhat unorthodox, maybe.I have come to love police sirens! Without having A/B compared it to a pai...

[quote user="mats"]Good start Dan!The JBL phenolic 2" driver is 2482.I would lower the crossover point as far as you dare, 300Hz or so.Now the 2226 will do what they are pretty good at.Later you will likely want to filter the 2445 around 2k.A 600Hz h...

Romy,I am considering a midbass channel similar to that you are currently using. The plan is to use the channel as a form of EQ to help rectify a large circa 40Hz room mode...bass cannons below the mode, midbass above the mode, and upperbass horn ab...

If you try/find an acceptable active MC step-up, please share your experience. I think the (stupid) Boulder op amp is the only one I've heard so far that does not sound severely "compressed" to me, and it really pisses me off that I have n...
