Mani, congratulations with Pacific.
You will not have problems to drive with balanced Pacific your single-ended amp. Juts buy a good quality XLR to RCA adapter or order XLR to RCA cable and you will be set. You do not even need to care about t...

Hi Romy, great site I just recently joined but have read your many posts over the years as I quite frequently end up here while searching the net for info. I recently purchased a pair of Super12 wharfedale drivers and thought with all your audio know...

[quote user="jessie.dazzle"]Romy, you may be right in suggesting that I am "going a little crazy in there" (I consider this a compliment btw)... so for now I decided to try some locally sourced precision metal film resistors (Vishays are not that eas...

Hi,this is my first post. This forum seems to be the hotbed for Goto discussion of some sort but there is barely any data but only a swamp of assumptions. So I bought a pair of SG-370DX drivers with S600 horns and measured them. Here's the frequency...

What do you know: have built another Melq monoblock and now I have a operational pair. They do fine, measure and sound identical. I did not close them up and keep them for now without the top and bottom cover as I will be doing a few minor adjustment...

Hi there
I can see Romy's face when he's trying to figure out Martin's time alignment strategy;0) I have Martin's 204 Hz horn with Fostex 208 E Sig. These horns are to be big to properly integrate with anything. They are OK with Fostex Lowther drive...

For those seeking some decent compression drivers that don`t cost fortune, I can suggest to try the Eighteen Sound ND1460A compression driver. It has aluminum dome and polyester suspension and 1,4 inch exit throat. Does it sound like S2 ? Probably no...

Ok, here's some calibrated sweeps. I ran the tetrodes in triode mode, with G2 strapped to plate through a 100 ohm resistor. First up is the western 6e6p.[img]http://www.hagtech.com/blog/images/6e6p.jpg[/img]I then built an adapter card th...

Well, I did some research and consulted with my network people and it looks like it might be unfortunately-expensive project. Still it will not be what I want.
They recommended me to go for what they call NAS (network attach storage). It tuned out t...

Dear Romy,
My tests showed 2 separate types of noise/interference being caused when TU-X1 & DA-924 were switched ON while the TU-X1 was set to OUTPUT FM: -
First noise/interference, the Sansui TU-X1 was passing an AM broadcast on VARIABLE OUTPU...

Romy,
I can't find a/the post(s) where you describe the advantages of using a 4 inch throat. Stereo-lab makes both 4 and 8 inch throat 140Hz horns but I don't think they could make an 8 to 4 inch adapter...
Also, would it be advisable to have t...

Absolutely flat response will usually sound as you've described it; listen to your ears. If you are hearing the opening bass line of "So What" via the sub, you must be running the sub pretty high in frequency to compensate for lack of mid-bass. From ...

Paul,
The idea of the not threaded forum is good that it is always there is opportunity to go back to all there and update own views, or to extend them. In many moths/years when the ML2 stop be a novelty for you, you might return to this thered and ...

Ok... Assuming the lack of time alignment is compensated for via a DSP:
There are likely large chunks of the frequency spectrum that go un addressed, and equally large chunks that are mall-addressed.
I would say that there are two main ranges ...
