JBL LSR305P MKii and Control 1 Pro Monitors Review

I know that this might have been answered a lot here but how many of you owners listening from about 1-1,5 meter away from the speaker, hear the twitter “hiss” and how annoying might this be?
I want a smal pair of monitors mainly for my SSL2+ interface and sometimes for my RME ADI-2 DAC fs used in another system.
Another option I’m considering are the Adam T5V
The space for the first ssl system is limited … for the second is adequate for 5inch woofer!
Thank you very much!!
I've got the 308p Mkii, and indeed that has hiss too. It's fine at 2m listening distance for me, and is inaudible at 2m. I can certainly hear it at 1m though. (I'm in my forties and can hear up to 15kHz+, so I think "most" people would hear this hiss at 1m). If you're playing music through it then you won't hear the hiss, but when nothing is playing you'll hear it at 1m, and probably not at 2m.
 
I am not sure how big a deal the hiss is as I sit 60cm or so from mine in a small 2x2 Meter room that is very well acoustically treated. Yes when it is silent you can hear the hiss but it is no louder than my Hackintosh that is liquid cooled. I still hear wall wart transformers over this.

So Dead silent (no), but it is pretty low.
 
Thank you for replying ... from what you say I do not think that I should go threir way unfortunatelly!
I am quite sensitive to sound artifacts of this kind. Even the very very slight hiss that comes from my main system in about 2+m away, at late night listening is annoying to me!

Sorry fo rthe off topic question but does the Adam T5V have less (if any) hiss?
We use Adam A5Xs ($500 / each) in some studios at work and they are quiet.. no idea on the T5V. Good luck!
 
One question I been debating is to upgrade these 305s to the 705P? I use the JBL sub also. Or the other option I been considering is going with the Genelec One Series but there is also a substantial price difference. Did consider the Neumann 310 but I think they may be too big for this space.

It is amazing for the price how well the 305s but I do find they compress pretty easy. As I am producing this can often make decisions on compression tricky.

In my case the room is not treated well so I suppose the hiss will be louder!!

That is a good question which I am not sure about. On one hand reflections could echo and cause a perceived loudness but I find with my treated room I am well more aware of anything coming out the speakers as the room is way more silent. I suppose ambient noise is more the actual factor here though.

Agree, the more proper room treatment, the more you hear the monitor / less you hear the room. I believe the hiss will be more noticeable in a treated vs live sounding room..

Won't recommend 705p if you sit 60 cm from them. They hiss pretty badly.
Buy other brand that doesn't have this flaw.

Louder than the 305?
One thing I like about JBL is the dynamics (Subjectively). I use my SVA 2100s still in the home theatre setup and also a good double check for mixing. I have found it hard to find a similar speaker so was hoping the 705s. But it may be other brands if the hiss is as bad as you say.

Didn't compared them side to side, but loud enough to be annoying for sure.

I use the 705P's (and the 708P's) mine have virtually nothing of a hiss. Wonder if the one's you heard were damaged somehow?

I have 2 705p and 1 708p. All of them has similar hiss. It's actually rather interesting hiss as there is certainly one-two frequency that stands out in this hiss, its not white or pink noise. I've seen this measurement in 7 series thread which is output to the woofer and it has that spike.
Sound and recording also measured 705p hiss and it was bad.
Maybe all of them are damaged then, but if 5 of 5 are damaged then qc is trash and even more reasons to avoid them.

It is a very valid point on the hiss and even my 305s when I am cleaning signals I can not rely on and usually go to my HD 800s headphones (about all they are good for). For a so called reference monitor this should not be there.

What's the source they're connected to? They might just be reproducing the idle signal of a source with inherent noise. Maybe??

All powered speakers I have used in the last 30 years have some hiss or amp noise - the 705/8's noise is comparable to the Adams we use and less than the Genelec 1031's in some of our studios. This is noise that is audible only when you put your ear to the tweeter section.

The 3 series has considerable more hiss at idle than any of them from a short distance.

It's connected to AES3 output soundcard. Check sound and recording, they have really loud hiss, Neumanns are 10 dB more quiet.

Sound and Recording the German mag? Will do, 10db is huge. When I was shopping I heard several Neumann monitors, thought they were excellent. Are you looking to unload the 705's? If you're not happy with them, PM me please. I know someone that is interested in a used pair.
 
I'm pretty happy except the noise, which isn't a problem anyway because I listen to them from 2.5 meters.
Just saying I won't recommend them if someone is going to listen as close as 60 cm.

I'm figuring that a listening distance of 1.5 meters and 45+ degrees off the tweeter axis would OK when it comes to hiss, then. I'm considering nabbing a pair to replace some 30 year old passive 2-way JBLs that AFAICT are doing a good job in an ambience/surround role in my 6.1 system, and I'm wondering if the 305 MkIIs would be a worthwhile upgrade given that their intended role isn't particularly demanding.
 
Is there a difference between the LSR 305p and the LSR 305p MKII? I finally found this original thread so wanted to ask.

Edit. I found some other measurements on the site: "There is some similarity, though it looks like the newer model might be brighter (but it also has a less pronounced 12k dip and slightly better DI)."
