For resonant frequency and mode shapes I think part geometry will be the most significant variable. I cannot quantify damping for PLA, because I haven't done any decay tests, but I think solid parts (i.e. 100% infill) with reasonable thickness will have at least acceptable damping (especially...

I'm not an expert, but here follows my understanding. I am curious to hear Timber_MG's comments on this topic. Unfortunately a room with chamfered corners does not reduce or obviate the need for bass traps. If it were the case removing or reducing the angle of the corners of a room with sheets...

Thank you for posting this. I have only watched a few minutes of the video, but I am already captivated by the conversation.

Since the first time that I met Oom Chris I fondly remembered every visit, conversation and moment spent in his company. A true audiophile and organ music enthusiast unlike any other I have met. An intellectual and prolific reader. A kind friend. I always admired him. Now, I will cherish the...

Orthogonality (math) is the topic to research for more information on how two channels of audio can be picked up by a single stylus.

Have you considered 15" or larger woofers (similar to the ones you are currently using) in a massive bass reflex enclosure to fill in the bottom end?

I had a pair of EV DL15W woofers, which have low fs and large VAS, a few months ago which may have been ideal for you Phase, especially considering how low you're crossing your horn. Speak to Kent Kassler he may still have them. If not, one of his contacts (where I got my pair) may have...

Are those DIY loudspeakers? If so, is there a build thread for them?

Yes, seeing as most audiophiles are in the majority of situations using a very expensive cable just to connect two pieces of cheap hookup wire why don't they just use the same cheap cable used inside the speaker cabinet and the same cheap hookup wire used inside the amplifier chassis outside the...

Oh Shunyata - the folks that sell an adapter which people can use to "burn in" their power cables. haha Sorry Gavin I don't want to appear cynical. Some reading may say that it is already too late for that. Thank you for the links. I'll play them tomorrow. Regarding dynamic current in power...

Those are the same folks that sell the acoustic dots and quantum fuses. What is this device of theirs called? I'd like to read about it. Do they explain what they mean by dynamic current capability or how a standard good connection or reasonable diameter conductor limits dynamic current...

Yes, I've seen those. Luckily (or perhaps unluckily) I don't foresee needing that much amplifier power for my setup anytime soon. My prior thinking could apply to this situation too though if one uses a 20A power conditioner. If my understanding is correct any amplifier that can run on a 20A...

That's what I've read some people post; current draw is a problem for bigger amplifiers. If a power conditioner is capable of 15A current delivery my understanding is that any amplifier that works on your wall socket should work on the conditioner and that anyone claiming the unit isn't capable...

I've read this too, but I want someone to provide a physics based explanation of their belief. My understanding is that if the power conditioner is capable of delivering 2500W of output and my power amplifier only draws 500W of power there shouldn't be any negative impact on the functioning of...

That is a cute unit. I need a larger unit for about eight components though. I like that the Samson has dual digital multi-meters display input voltage and load amperes of both the switched and unswitched outlets, LED lamps that pull out from the front panel to illuminate other components in...

Not entirely unknown though. https://www.audiosciencereview.com/forum/index.php?threads/surge-suppressors-are-surgex-units-the-best-available.2262/ https://www.sweetwater.com/c960--SurgeX--Power_Conditioners The unit on that for sale advert does look a bit rough though and not being able to...

Which model of theirs do you have?

Thank you. I recall you sent me a link to one for sale. I should perhaps have gone for that. It has less features than the Samson unit, but the Furman has two more output sockets. Who knows which unit has higher quality circuitry.

I think he is asking about this exact unit because of the advert. I am also looking for a power distributor with surge protection functionality. That SurgeX unit looks good, but I can't find any info about the RLi unit specifically. I do find the SX-1215-RTi units online though. I've been...

Fingers crossed. If the amplifier was operated with the front door of the radiogram closed while the back of the radiogram was pressed against the wall there would be poor airflow through the amplifier chassis and the ambient temperature of the enclosed space that the amplifier is situated in...
