In a couple weeks I'm bringing some of my audio equipment to a volunteer event where they're taking over around a 600x600 foot (180x180m) convention center space. Right now, I have some EV ZLX-12BT PA speakers and an active sub. Everything will be set up at one of the columns near the middle...

I have a Crown XTi2000 amp laying around waiting to be used. There's also an upcoming event I go to annually where I bring a sound system to play for a huge group in a huge convention center space. Until now, I've just brought a boring old Samson PA speaker. Now with the latest updates to my...

I'm looking for something to replace my MOTU M2 because I want better mic and ADC quality. I'm looking at the RME ADI-2 Pro FS R versus the UltraLite Mk5 because they're the best and cost doesn't matter because of a special financial situation I'm in. So, which one has a better mic pre-amp...

At my local hardware surplus store there's this clean but old Radio Shack "100w" "PA" amplifier sitting around for a mere $40. I couldn't tell when exactly it was made but it was rack mount with an attached 2 prong power cord (no ground) and in place of the VU meters were these placards saying...

I have just calibrated my system to have a nice, sloping down curve in the bass region with the spikes ironed out (fixed a little more after taking this screenshot) but now I'm listening to music and it seems like there is no bass. So, this is where the rubber meets the road. Should I opt to...

Is there any interface with S/PDIF or AES output support that also has a volume knob other than the MOTU UltraLite Mk5? I want one for my KH750 setup which supports digital input and I believe doing everything digitally might reduce latency.

Something that's been REALLY bugging me is how there has been a focus (not recently but always) on tiny little details that nearly don't matter. For example, just look at cables, MQA, effect plugins for mixing and mastering, better-than-audible SINAD, you get the idea. Meanwhile, "nobody" is...

I know cables nearly don't affect sound quality (they can if they're corroded, super duper long, or are unbalanced without shielding) but I feel worried about the ones in this cute little XLR adapter I just got 2 of: https://www.amazon.com/dp/B000068O59 In comparison to most other XLR cables...

Anybody else interested in how music affects surgery performance? There is actually some research on this, but notably, little gives specifics such as what music is played, nor the sound systems they're using, and the acoustics of the operating room, despite how much these factors were already...

I recently got a Fosi ZD3 DAC because I needed the balanced output. However, the big volume knob on the front feels a little too jiggly for an otherwise great quality device, does anybody else have the same problem? If you do have the same problem then we can rule out this being due to a bad unit.

I'm considering swapping out my single Kali WS6.2 sub with one or more sealed subs because the transient response just isn't good enough for me. I have the Neumann KH150 speakers, so my first choice was the KH750 with how good its group delay and frequency response is. However, there are so many...

Here's how you can find what music has bass in stereo so you know if you need stereo subwoofers or not. I use Linux so I also use EasyEffects which makes this task shockingly easy. 1. Add a Stereo Tools widget and invert the phase in one channel, left or right 2. Add another Stereo Tools and...

Due to unforeseen circumstances I now have a 1800 watt 18" PA subwoofer (EV ETX-18SP) sitting in my parents' living room, where I've set up the TV with a Hisense HS2100 soundbar. This soundbar includes its own sub which appears to connect over BT, but I can't connect to it directly with my...

I love my new KH 150s but I feel like there's a slight problem with them. They have an underdamped step/impulse response, which means that any impulse coming in will ring a nonzero amount. This is largely due to the speaker's ported design. To make sound through the port's resonance, you first...

What is the material of the woofer in the Neumann KH 150? I cannot figure it out because my white ones reflect all the light off my flashlight and there's no other info out there on it. I'd hope it isn't paper because then that opens it up to moisture damage which would be super bad for an...

LTT shows that by buying other people's "junk" used, you can make an impressive sound system for cheap! What do you think?

How do you feel about the idea of OSP or Optical Signal Processing for sound systems? I'm already working on a DSP (Digital Signal Processing) project here but there is a whole other world in optics waiting to leave the laboratory. The idea is to use optical components like semiconductor...

I really want to get a pair of KH 150s to replace my Kali LP-6v2s which have hiss and noticable distortion. But I don't like how a pair is a whopping $3500. However, with upcoming US tariffs, there's a huge chance they'll become even more expensive in the future. Should I buy them now or wait?

I can't believe there is only ONE article on the internet (https://addictedtoaudio.com.au/blogs/how-things-work/let-s-measure-the-bluetooth-codecs-which-performs-the-best) comparing all the widely available Bluetooth codec options to see which one performs the best. So, I decided to do my own...

In one of my gym audio setups, I'm using a pair of EV Eliminator Double speakers from 2004 (3 way) which are rated 400 watts at 4 ohms each. They're connected to a Crown CE2000 amplifier which is also from around 2004. With how poorly PA amps tend to be rated (the Crown XTI4002 has only 66dB...
