[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...

Okay, since you ask, I think I have said it before, and I consider it kind of pointless since we are talking more for the sake of nostalgia not anything to do with what we may do with our audio systems in the present. Anyway, yes I owned the Rosewood...

[quote user="Jorge"]Hello Anthony,I did experiment with metal tubes for bass in a sealed configuration as you are planning. The weight of them, even made out of thinner than you would like steel, is prohibitive. If you make them out of aluminum pipe...

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="noviygera"] Question, Romy:Why do you suggest to add the extension on the back, not the front, as B. Edgar suggested. He specifically commented that the MOUTH area is too small and said the throat size was OK?[/quote] Herman, the mouth a...

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...

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 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...

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...

[quote user="hagtech"]Yes, steel chassis can be both good and bad. It likes to conduct magnetic fields, so you have to treat things appropriately. A little spacing under a choke can go a long way. Otherise you have a 120Hz motor.&nb...
