Neumann KH 150 Monitor Review

[Trell]

Can’t cotton to their “overfed” look.

Overfed? What do you mean?

That's one take on the meaning of "overfed" Genelec monitors.

Fun fact: one of the two - I don‘t know which is which - is related to Bruce Willis and regularly calls Willis‘ mom.

No, I am not kidding.

The forum software on mobile, by repeating the inserted images as attachment thumbs of the same size, is doubling-up on your hilarious joke. This is too much, I can't take that many curves!

I've been offered a good deal on a secondhand pair of KH150's in as new condition. I was planning to change my Eve TS108 sub to the KH750 to use with my KH120's but it would possibly be cheaper to replace both the KH120's and Eve TS108 with the KH150's I've been offered! What would you advise?

Get the KH150 and then also some new subs obviously.

Ha yes dream on. That would be great but I don’t have the budget for KH150’s and subs!

 

[HarmonicTHD]

I’d keep the KH120, get the KH750 and some MA1 room correction.

Well maybe not now but these monitors can last a long time.

Depends on what you want/need from it. KH150 goes to 36Hz full space and around 30Hz in real room. It has extremely low distortion even at 100db pair and even at 40/50Hz. But in can't play 18Hz as KH750. But KH750 seems to be weak and distort a lot if played loudly. At lower levels with MA1 KH750 + KH120 can be very nice too.

Good job Neumann, finally a 6.5” 2 way speaker I might buy.

Now Neuman when are you going to release that dual 12” 3 way with a 5-6.5” mid?

Maybe I’ll be able to hang up my boots and just enjoy the music.

If you read Neumann‘s recommendations you will find that they recommend two KH750 for the KH150 exactly for that reason.

Neumann could offer larger versions of the KH750 to match their higher output monitors, like Genelec does. They could even make it ported, also what Genelec does.

The KH750 is a nice subwoofer but it sure does have limitations.

It's bizarrely small for a sealed box sub that goes that low. The Rythmik I have has a 2" larger diameter driver and a substantially larger cabinet.

Sure, but here people want more output than the KH750 can deliver.

Neumann does have a gap in their subwoofer range with regards to output.

Yeah, that's why I ended up with the F12 instead of the KH750.

Yeah but EQ is the only reason it measures that low and it isn't meaningful in any way beyond looking nice on a graph. I compared the KH750 to a BK XLS200 a couple years ago when I was picking a sub for my KH 80's and the difference was basically nothing. The XLS200 is even smaller and costs around £350. It's just lacking DSP/High pass filters etc.

Hello Teashea! I'm new here and I would like to ask you how you can seriously evaluate your speakers in such a non treated reverberant room? I don't want to be offensive, just asking. I can't see any acoustic treatment in your room. It seems, that you have enough money for buying many Neumann monitors, but I'm afraid that without any reasonable treatment they never can sound as good as they are. I'm sure, that the room is number one and plays the biggest role in sound perception. And speakers are way behind. I'm thinking if to buy KH150 which are for my small room 3,6x4,7x2,7m enough with their 36Hz -6db. Or to buy new KH120 II which are way more cheaper and may be even better in midrange distortion and then add some quality subwoofer to let them breath a get more headroom. They seems great speakers except design...

First of all, the room as substantial sound treatment. The wall panels are my proprietary design. One must also consider the size and shape of the room. Second, one must understand nearfield listening and the science involved in it. With very nearfield listening , it is important to consider the contribution of direct sound level compared to any reflected sound. Third, understand that not all reflected sound is bad. A certain amount of spread frequency reflection is good. A dead room is a terrible listening environment - if one could achieve that. I have been a music producer for sixteen years and this is my fourth studio. Here is a photo of the other side of this particular room in my studio. There are also large opening on the side of the room to assist in getting rid of standing bass waves. I also use several Focal, Audeze, BD and Neumann headphones to check and compare things.

I think that the KH 150's would be a viable option, depending on the discount you are offered - which to me should be more than 30%.
