That 428Hz artifact
That's the frequency chosen for the test tone being played - it's the fundamental...
That 428Hz artifact
And if you use the boundary EQ at -3 dB ?what is the minimum acceptable distance of wall? could be problem placing the speaker near 20cm from the wall?
Thanks!
That's weird, I use them for TV/movie watching in a simple 2-channel setup, as well as for music listening at over 2 metres in I guess a medium sized room, and I rarely use them above the 9th indent, normally on the 7th - and there's 20 indents, so I never use them above half volume, and that's plenty loud for me whilst using a -3dB preamp too......that's with a 2V DAC for music listening and whatever my TV can output at max volume through it's connection which I worked out is less than 0.9V after it's gone through my miniDSP 2x4 processor (-1.5dB preamp built into it's EQ).I bought these with the LSR310s to use as a home theater 2.1 setup for the last 3 months or so. I think I'm at the point of selling them though - they simply don't get loud enough! And this is in a small/med room (3mx5m), about 2.5m away. Like the review says, the amplifier is really lacking. The worst aspect is when watching some multichannel movie content that gets quieter when downmixed to 2.1, and I have to crank everything to basically 100% to get it audible. There may be some hacks around this (like boosting volume to >100% digitally at the source) but for HT I think it's just too much a pain. If I was using them for nearfield only I'd probably keep them.

Same feelings. I have 3 LSR 308 in a room of similar area. Gets loud beyond my tolerance and frankly that of many, with 2 LSR 305 as surround, I have reached, on an experiment, above 112 db. That’s loud in any book. I posted the results somewhere in ASR. It was unbearably loud. Something is not set up correctly.That's weird, I use them for TV/movie watching in a simple 2-channel setup, as well as for music listening at over 2 metres in I guess a medium sized room, and I rarely use them above the 9th indent, normally on the 7th - and there's 20 indents, so I never use them above half volume, and that's plenty loud for me whilst using a -3dB preamp too......that's with a 2V DAC for music listening and whatever my TV can output at max volume through it's connection which I worked out is less than 0.9V after it's gone through my miniDSP 2x4 processor (-1.5dB preamp built into it's EQ).
Depends on how far you sit and, of course, background noise. At 2.8 meters, my seating position, I can't hear these with the background noise at 40 dB c-weighted measured on an iPhone 11 and the dBMeter app. At the same distance and background noise, I seem to notice that of the LSR305. I will perhaps measure and report but I never cared about their background noise.I'm contemplating getting these for a simple TV based stereo setup.
A question to actual owners / users: Is the idle noise of the 308P a problem? There are conflicting statements about this on the Net.
Another question: Some say they do have auto standby? (some say the noise disappears after some time).
The other option would be Adam T8V, allegedly almost noise-free but some find the treble annoying...
Hi, I think these are good speakers for TV/movie use, they have good smooth directivity so provide a uniform experience off axis, and they've got a good frequency response curve too, but you'll want to put the HF Trim Switch on the back of the speakers at -2dB to make it an even flatter anechoic response.I'm contemplating getting these for a simple TV based stereo setup.

Re-reading your post this is not the fault of the 308. Many movies dialogs are mastered too low. You have to really crank up the overall level to hear these well. or, if you have an AVR and a discrete center channel, raise the level of the center channel for intelligibility, with the results of ruining the audio Multi channel audio reproduction... when things get even moderately loud...

See if you've got anyway of visualising the dBFS level after Plex is downmixing, after which point maybe you can find a way to digitally boost all frequencies so it's closer to 0dBFS whilst leaving enough headroom to ensure you don't get digital clipping, but don't know enough about your setup to know if that's possible.I'll have to experiment more then, hmm. I'm going Plex on nvidia shield -- (usb) --> SMSL SU-8 (at 100% volume) -- (balanced) --> LSR310 at -10db sensitivity/60% -- (balanced) --> 308p at -10db/100%.
I think it is most likely an issue w/ Plex downmixing 5.1 and the volume levels dropping.
Follow-up: Now I got them, and well, in a desktop setup the hiss would possibly be a problem, I can hear it up to 1,8-1,9 m away.I'm contemplating getting these for a simple TV based stereo setup.

Don't forget to flick the HF Trim Switch to -2dB as a quick rough optimisation, makes them more anechoic flat. Or if you've got the ability to apply parametric EQ, then you could try my EQ that turns Amir's measurements of these speakers to a smooth Listening Window and at the same time a flat on-axis response (Anechoic EQ) - listed in my post here:Follow-up: Now I got them, and well, in a desktop setup the hiss would possibly be a problem, I can hear it up to 1,8-1,9 m away.
No hum or such, just "pink noise" like hiss. A non-issue for the intended use case, however.
This was what I did spontaneously, after just putting them on a table to test for function because the default treble was slightly too much for me. The final setup will be in a few months in my house in Poland, to which I'll be moving back from Germany. I decided to buy early, just in case...Don't forget to flick the HF Trim Switch to -2dB as a quick rough optimisation, makes them more anechoic flat.
Nice. (I edited my previous post while you were typing your reply - added a point about parametric EQ and a link to it.)This was what I did spontaneously, after just putting them on a table to test for function because the default treble was slightly too much for me.

Hi Amir, just trying to optimise the levels going into the back of my 308p mkii speakers, and have a question. I did some googling, you mention 0 dBu, and I found out 0dBu is 0.775V (RMS). From your picture you have the speaker on -10 dBv which I've found out through googling is the equivalent of 0.3162V (RMS) as a standard. If using this speaker with modern DACS that output 2V RMS then do we need to make sure we dial it down digitally to output the 0.3162V as a max when used on the -10 dBv setting, or would we also be safe using at 0.775V output (like you did) for the -10 dBv setting on the back of the speaker, or even higher voltage? This is in reference to you noticing clipping at high input levels.Well, there is that gain control in the back so I don't have absolute levels. I set it to 0 dBu for the 96 dBSPL with the gain setting near what you see in the picture.
I just picked up a pair of these from Amazon at $199 each. Mine are dead quiet when idle. I got them 4 days ago. This thread has been very helpful. They were too bright with the HF switch at the stock position. The -2 dB setting is great. I really like them. Currently feeding them via Chromecast Audio analog. Have the SMSL DO100 Dac on the way,I'm contemplating getting these for a simple TV based stereo setup.

Have you bought the JBL or the Adam? I guess the latter - I got the JBL and the idle hiss is quite noticeable (until the standby kicks in, which allegedly only the CE labeled version has). At very close distance (<1,5m) the idle noise would be a bit annoying to me.I just picked up a pair of these from Amazon at $199 each. Mine are dead quiet when idle. I got them 4 days ago.
