In the Thread: Garg wants more horns.
Post Subject: ...and we're back.Posted by Gargoyle on: 8/1/2024
Starting at the top. I have some HF drivers on the way, so I thought I would make a few cones to try when they arrive.
On top of paying too much for the convenience of amazon, I also unintentionally ordered mylar drivers instead of phenolic. Do I care? I don't know.
I just want to build something without the usual hifi angst over parts selection, especially ones that are nostalgic in others eyes.
I have parted out my SETs and Altec speakers. Tonight I am listening to a pair of monoprice monitors with only one tweeter. It can get lower than this, but not much.
The DE10 tweeters will need to be run above 2-2.5Khz. These are 884Hz tractrix horns. I figured it was as good of place to start as any.
ChatGPT gave somewhat conflicting information on a somewhat ideal horn size for this driver depending on what it thinks you are asking for. Perhaps more nuanced than I give it credit for at times.
In order to facilitate experimentation, I purchased a pair of generic pro audio style 234XL 4-way crossovers. I actually like the rack mount style but will be soldering past the XLR connectors. I was tempted to DIY some ESP or Marchand active units, I even hoped that these would be through hole electronics should I desire to upgrade components. However it did not make sense cost wise, considering these are in cases and have power supplies. About $100 Canadian each.
Eventually I will build some little tube amps again, for the time being I will be focusing on building the speakers and using class D. I have three TPA3255 amplifiers to use as stand ins. I don't really have a fourth amp in mind or anything more suitable than another D amp, would probably start building tube at that point.
I also bought a USB mic (Umik-1) to use with REW, no matter what you buy it is always wrong. Using this particular mic for time alignment is convoluted. Again, lets not fuckin obsess over every purchase, just I really thought I knew what I was buying, as say compared to a speaker DATS or a mic and computer interface etc. Regardless I am looking forward to actually doing some in room measurements which should be cool.
