Klein + Hummel O 300D’s

WEBLOG
When I started my search for a killer pair of studio monitors years ago, I had no idea that it would eventually lead me to my current favorite piece of gear in the studio–the Klein + Hummel O 300D. Yep, I’ve gone and done it, and no, it did not cost me almost $7k (I was incredibly lucky to find a pair on ebay). It was listed for $3,000, and as I watched and watched, not a single person bid on it, so I went for it. Thank God it did not have a sensible reserve price, because anyone who knows anything about high-end gear knows that the 300D’s are a steal at $3,000. This past couple of years in general has been rough for me, and the 300D’s sure soothed the pain a bit. Just look at those soft curves on the waveguides:

Here they are, sitting pretty in my studio (need to add some Auralex Mopads to cushion their bottoms):

Here’s a Sound On Sound review that reads like a love letter. I generally prefer Hugh Robjohns’ reviews to Paul white’s , as Paul tends to be more cautious with negative remarks (for the sake of not pissing off the advertisers?).

You can find out more about the sexy Germans from Klein + Hummel’s website.

I’m not sure if I can add anything to Hugh’s review–he’s certainly heard a lot more high-end monitors in his career, so he’s bound to know a lot more. If he says the 300D’s are amazingly good, then who am I to argue? My own experience with them (after having had them for a few days) is that they are certainly very revealing, accurate, with an open soundstage, non-fatiguing, and have the cute little K+H red lights in the front that blinks if you overload the internal limiter–which I’ve yet done (I’m pretty sensible when it comes to monitoring levels–I try not to exceed 90db, and usually keep it at around 80db~87db). For such a small size, they definitely do deliver unbelievable big sound, yet remaining accurate and not hyped in any frequency range. I’ve thrown just about all kinds of recordings at it–classical, industrial, metal, electronic, jazz, vocals, rock, pop, film/game scores…etc and they have performed beautifully. They do reveal bad recordings for what they are though, whereas lesser monitors mask the shortcomings. I’ve listened to some of my own recent cues, and I’m hearing things that have changed my mind about how I should mix them. I don’t think I’ll be using the digital inputs, since I’ve read from other 300D owners that they aren’t really all that better than the analog inputs.

All in all, I’m just thrilled to have the 300D’s in my setup, and I’m also ecstatic over the killer price I got them for. I doubt I’d want to add the O 800 sub to them, since the 300D’s go pretty low already (definitely lower than the listed 40Hz, since it’s a closed enclosure and 40Hz is what’s rated as within the flat response range). Maybe if one day when I need a larger studio, I’d add the sub.

I want to give a shout out to Jeremy at Guitar Center’s San Jose branch. He was a very cool guy who helped me demo a bunch of monitors and allowed me to move them around (which the stores typically don’t allow) to get more accurate listening positions for A/B’ing different pairs.

I might have ended up with a pair of JBL LSR6328P’s if I didn’t see the 300D’s on ebay, since I was quite impressed with those during my last listening test there. The 6328’s blew the 4328’s out of the water (I had a good impression of the 4328’s until I heard the 6328’s), as they made the 4328’s sound almost timid and limp. The 6328’s had much nicer soundstage, and overall a lot more articulate and dynamic (not in a hyped way).

I got to test the new Mackie HR824 mkII’s while there too, and I was quite disappointed. The treble was rolled off and sounded like there was an invisible blanket over the high frequencies (maybe Mackie chose less fatigue over accuracy?). It’s still got that fat bottom end like the previous version, which may or may not be accurate, but for the bass heads, they’ll buy them just for that.

I got to hear one of the Blue Sky 2.1 systems (finally!), and they were definitely nice, but sounded like there was a hole missing in the frequency range (lower mid’s). It must be due to the crossover issues in the 2.1 setup.

The 300D’s weren’t my only recent ebay winning bids–I also nabbed a Kurzweil PC2X master controller keyboard:

I almost went for a CME UF-80, since I finally got to try one out at Leo’s Pro Audio (in Oakland) recently, and the action is not nearly as bad as some have claimed on the internet. In fact, it felt remarkably like the Kurzweil and Fatar’s piano action. I was going to get it because I wanted to connect a Yamaha BC3 (breath controller) to it, and it comes with the connection ready (otherwise you’d need to spend a couple hundred more just for a converter). But when I saw the PC2X on ebay, I had to go for it, since I could connect a ribbon controller to it, AND it’s got the breath controller port too, not to mention it comes with some pretty good sounds. My logic is that if I’m paying the same price, why not get something that actually makes a sound–I might find some presets I really like. I don’t need all the knobs and sliders on the UF-80 anyway, since I already have a Novation ReMOTE 25 SL. I ended up getting the PC2X for $711. Not too shabby at all.

I nabbed a few other items off ebay as well–a M-Audio 4×4 MIDI USB interface (my Midiman 1×1 is not going to cut it now that I’m adding more gear, since I don’t want to do too much chaining), and a Behringer Xenyx 1622FX mixer (please don’t groan. Not all Behringer products are crap. Plenty of Behringer’s products have gotten great reviews. Besides, if I hear any unwanted coloring/noise from the Xenyx, I’ll immediately get rid of it and get something more “respectable”).

All that remains is pretty much acoustic treatment. I’m willing to spend up to a couple of grand to treat my studio, but any more than that, I might have to consider the DIY solution. I’m currently looking at both Realtraps and Auralex solutions. I’m a lot more impressed with Realtraps so far, since their customer service is a lot more in-depth, and they are the one company that gets name-dropped constantly at high-end audio forums by reputable mastering engineers.

I’ll need a good all-around mic too, since I don’t have a decent one in the studio right now (just a couple of el cheapo’s). I haven’t had the need to record vocals or acoustic instruments for a long time now, but that’s going to change real soon. Maybe something like a Studio Projects C1, Shure Beta 87C, or RØDE NT1-A.

    Incredible work man, these have to be the best pieces i’ve seen! Wish my art teacher frosty could have shown us graphic design like this, they’re wicked!
