| A Question on Speaker Driver Efficiency I encourage anyone wanting to follow along, to grab XSim crossover simulator, and examining the Frequency Response, Watts Dissipated and Impedance charts. http://www.diyaudio.com/forums/software-tools/259865-xsim-free-crossover-designer.htmlThe "b... | |
| Sound differences between Copper and Aluminum Bus Bar Electrical Panels Where exactly does this end, and what exactly are you training your neural paths to do for you? I mean, if this is all that, you need to go fully off grid, and design some audiophile grade inverters. Maybe just go full battery powered listening ro... | |
| A Question on Speaker Driver Efficiency Hi OP! XSim will help you evaluate the impedance and relative output. You can try making up circuits of various speaker drivers, and the output volume AND impedance will change when you do. :) So it gives you immediate feedback to possible choices... | |
| New Speakers ... Can't Stop "Listening" Hi @kalali - This is a digression. I'm not saying everyone should design their own speakers, nor do I think saving money is the reason to do so. I do think every audiophile should get their hands at least a little dirty at least once in their hobb... | |
| New Speakers ... Can't Stop "Listening" @markalarsen I think you have a wonderful perspective! And yes, selling kits used is a B, but on the other hand, you did not invest that much to begin with. Direct comparisons matter a great deal, and it is horribly unfair to designers at JA to at... | |
| New Speakers ... Can't Stop "Listening" Shame I can't post images. So looking at the Stereophile review for the Perspectives, and the data at Madisound, the crossovers are entirely different. One of the main results appears to be the lowering of the tweeter / woofer frequency with the J... | |
| New Speakers ... Can't Stop "Listening" Found the review for the JA Perspectives, https://www.stereophile.com/content/joseph-audio-perspective-loudspeakerwhich are closer in line to the SEAS kit I was suggesting. https://www.madisoundspeakerstore.com/2.5-way-speaker-kits/seas-delling-... | |
| New Speakers ... Can't Stop "Listening" hi @rlb61 - Well, without measuring there is no way to tell exactly what was done for Joseph Audio. This is quite typical work by the way. Changes to the impedance, or suspension to accommodate target enclosures or crossovers are often done, plus ... | |
| New Speakers ... Can't Stop "Listening" By the way, as I was looking for something entirely different I found a Seas 2.5 way tower kit at Madisound, using similar parts. Worth checking out, especially for the price! Around $1,800 for the drivers with crossovers. You could probably get L... | |
| New Speakers ... Can't Stop "Listening" I have not looked inside the JA Pulsars, but I have to say, the impedance curve and measurements lead me to believe these are fairly conventional crossovers, but Kudos to JA for being so well implemented. The curious thing is the dip just below 2 ... | |
| New to DAC, need advice. Well, if you wanted to upgrade for cheap, the ZDac 2? | |
| New to DAC, need advice. I _really_ like the sound of the ZDAC. For the price, and when it was available, it is a really nice piece of kit! If you are going to upgrade, you want to look at Schiit or Mytek. On the other hand, the ZDac can make a nice DAC for your desktop. ... | |
| DIY - Affordable 2-ways to rival high end So undoubtedly some will ask "What do you mean rival high end?" Tonally these designs are really really good. The XT25 tweeters and derivatives have been used in speakers from Krell, YG Acoustics and Magico. The mid-woofers are also super smooth s... | |
| DIY - Exotic 2 way Hi Granny,Sorry. Look for the Mundorf MA 30. Here is at least a review:http://novo.press/mundorf-ma30-custom-made-speaker-kit-silvergold-series-review-worlds-first/Unfortunately it seems that I may have posted a kit which is winding down. It did n... | |
| DIY - Two kits using similar tweeter to Tekton I think those three brands of speakers use a peculiar type of tuning that happens in the "high end" which is quite different than this particular kit. Dynaudio is also different in that they often use a W shaped house curve. Each of these approach... |
