priviet. I tried many ways. I cut the front outside faceplate open, and put a second driver on it. So that two drivers were firing onto each other face to face in one single hornthroat, rest normal single K. To my surprise the output didn't increase ...

[quote user="Romy the Cat"]I can’t predict what sound will I get with hardwood floors and how it will be different from think wall-to-wall carpet that I have now. Currently I have architect wood joists 30 feet long running at the bottom of the floor....

Hello Guy,Please excuse the rapid fire response, bit short of time today.1)Your comments about the Io cart are most interesting; clearly it ain't about saturation. Here's another idea: if the domains in the magnetic material limit resolution (leading...

Amir, what you have written is not a philosophy, it is not a path that guides decisions, not a document what gives others insight into what music does to you and why. I have been following your posting, and to be honest, it sounds more like an audio...

Moreart, somebody sent me this link last year. You are surely the DIY pioneer of back loaded Manger.As you probably know this is a touchy speaker to work with. Rated at 91 dB/W input by the factory, we measure ~91 up to near 92 dB/1W/1m in our two mo...

Hi Romy:No need to reach for your medical glossary. The medical condition that I call 'Imponderabilis Neurosis,' is only the preserve of highly disturbed individuals such as myself (Hamlet seems to have exhibited symptons which are highly indicative ...

Amir, I told of my own approach to wall power in other threads. Basically, I tried to make my gear as tolerant of AC variations as I could without simply smoothing everything over. My DAC runs on battery power. I modified the power supply and changed...

I stopped by today in a local warehouse and picketed a 4x 16” fiber pipes and 2 two 20”. I absolutely love the effect. As soon I brought the tubes to the room and took the cover off in the hall room turned to be much quieter at HF. I did not expect t...

[quote user="op.9"] One thing nobody has mentioned is using the room’s corners. Is this a no no? I’ve been trying use McBean to model a horn exiting into the corner – with a middle ‘mouth’ about 1m squared - and using a conical approximation as the r...

More days came, with different electricity and it looks l like the PP2011 hold its stand – I did not detect a significant change in Sound so far. I gave a scoop plagued in the wall all time and I did not see so far a relation between the wave profile...

[quote user="rowuk"]Alex, I have a APC RT UPS which is a regenerator and UPS in one. I use it for on site recording as you never know what you get from the wall socket. Dimmed lights, PA and all sorts of other devices like air conditioning and refrig...

Hello Romy a long time visitor now a member. I have always been interested in what improvements can be made to my incoming power. I use a BPT 2, PS noise harvesters and quite lines through out the house. My system has always had very good sound...

[quote user="PurePower"]The PurePower batteries provide power to the AC regeneration whenever it is required. That could be during a black out, it could be during a brownout, it could be for a fraction of a cycle it could be for 10 minutes. The simpl...

It might only appear that it is irrelevant subject. In reality this is the subject of my LONG DREAM… and I have almost realized it.
I spend entire days to redo the Air Conditioner system to accommodate it for my listening room. The house has a...

I think that picking a DAC is like picking speakers - regardless of the price, we don't know what we have until we get there. I do not think that it is possible to compare digital and analog playback forms. With a turntable we have as many choices (g...

The visual element of the brief shoyld be able to be achieved by doing thing nicely, thought out and with good materials.I am aware of the no parallel walls and this may well be utilised into the design. A simple stud wall, set inside the perimeter w...

I set two multicells with LF-enabled S3 drivers. I set them on the outer side of Macondo MF. Playing with crossover, volume and towing of the multicells I was able to a degree to get the effect that would like to get. The pointing the multicell...

I have come across this company mentioned in a preview on '6moons,' and the information on the company's website suggests that this is in theory really a complete solution, and one that makes sense even to the non-engineer that I am to...

I feel strange tonight. I woke up at 2.30AM to feed the diabolically-smiling baby and as Thomas went back to sleep I keep walking back and forth of the listening room for 2 hours, having quite bewildering feelings. As Amy the Kitten moved with me we ...

There is a lot on this site about room treatments, if you take the time to look for it. For example [url=http://www.goodsoundclub.com/GetPost.aspx?PostID=1829&Phrase=sails]remember this from a few years back?[/url] I suggest you browse the site for a...

I really enjoy this site. Romy has a fresh view that is actually easy to understand, if one simply reads instead of interpreting what he writes.Still, a view from "higher up" is something that many of us are not privileged to. Looking at the major co...

A friend stopped by tonight when I was test-listening my midbass horn. He got freaked out from the size of the thing. I played for him some Gerhard Oppelt’s organ recordings. He told me that I am crazy, like I do not know it myself. Anyhow, he made a...

I talked for a couple of hours today with a local Solar Power technician, I sort of told him all the gear I have that would need to run on batteries and we got a shaky number; from that number he started calculating a bunch of panels and batteries a...

Oops, I almost forgot the size of 14”. This is kind of off the wall size but still there was two exceptional drivers in this size that I met.
The first is JBL 1400ND. The 1400ND was initially used in JBL K2 system. It had underhung voice coil, neody...

Ok, I have been experimenting with placement : Long wall versus short wall. Though the frames have wheels and roll very easily, my room is cursed with an elevated platform smack in the middle of everything (about 14 inches higher than the main floor)...

Hi everyone,It is quite ironic that the day I hear from Fane telling me that the Fane 8Ms are finally ready, I should receive this update from my horn maker maestro. Russ Collinson of Layers of Beauty. Russ, if you ever read this here, please take a ...

Lx, I do not think that my any of my PP2000 or PP3000 were been modified by APS specifically to suit my needs/complaints. Well, I did complain if I see something that is not right but there were (to the best of my knowledge) not customization for my ...
