Studio 230


2-way 6.5” Bookshelf Loudspeakers

Sonic dynasty fused with high-tech destiny

Place a new kind of legend on your bookshelf We admit it: we’ve made a loudspeaker that wouldn’t have been possible in another time and place. But so what? We’re in this business to break all the rules of impossible. Meet the new legend in town: the JBL® Studio 230 bookshelf speaker. As part of the new 10-piece JBL Studio 2 loudspeaker series, the Studio 230 was built to speak the languages of both legacy sound and forward-thinking technology. Tested relentlessly in the world’s most advanced sound research lab – our own – as well as pitted against competitors in real world comparative listening studies, we aimed this one for the fences. We constructed a front-firing 6.5” PolyPlas midrange speaker and a rear-firing Slipstream bass port to envelope your senses in tight, powerful bass. Others might have relaxed and called it a day – but that’s not how we do it at JBL. We took further cues from our work designing the world’s most legendary recording studios, and gave our Studio 230 the kind of tech that makes for premium cinema listening: a 1” CMMD® Lite high-frequency driver that ensures low-distortion, and a High Definition Imaging (HDI) waveguide design that offers pinpoint sound imaging and firm natural balance. Then we topped it off with seductive features like gloss black paneling, soft rounded edges, and your choice of either Black or Espresso woodgrain finish. We combined the power and precision of high-tech audio with the sleek urbanity of “it-factor” design. For those able to hear the truth, we’re confident you’ll hear it –full volume – upon first listen.

Rated 5 out of 5 by from An outstanding loudspeaker - bought my second set About a year or so ago, I bought my first set of Studio 230's from JBL. I loved the speakers so much, that I bought a second set to match with a separate Yamaha amp that I own. I also own a set of the ELAC B6 loudspeakers, so I was able to compare them with each other. The ELAC B6 has slightly better bass, but there was a noticeable, higher sound quality, overall, with the JBL Studio 230's. My musical tastes run the gamut from acapella choir, jazz, folk, rock, punk rock...etc...you name it. These are genuinely high quality speakers - so match them with an appropriate amp that matches their 20-150W range. Soon, you'll find yourself immersed with wonderful sound. The large numbers of 5 star ratings from other satisfied customers reflect just how good these speakers are. Well done, JBL.

Rated 5 out of 5 by from Amazing clarity. First off I want to know how these woofers are being measured because by my measurements this is closer to a 5.25 than a 6.5. That being said however you will not miss the extra inch in size as these speakers really put a very loud clean bass that I never imagined could be reproduced in a speaker of this size. I had some old pioneer 8in three way speakers and not only are the highs and mids much clearer but the bass is actually deeper and much less in your face. The best part of these speakers is how soft they sound. They have a very calming sound to them. No matter the music I play they never seem to be harsh or too upfront. They have a very smooth signature to them. Seeing how they perform now I would gladly buy these again and will tell everyone about them.

I am using the studio 230 as left and right surround speakers, at what height should these speakers be?. The manual says that the tweeters should be ear level and also says that if you use as surrounds they must be 1.5m - 1.8 from the floor.

Asked by: Vijen
Dolby Labs says the surround speakers should be a minimum of 2 to 3 feet above the listening area.

I had mind set on the Arena 130 but after reading all the positive reviews on the Studio 230 I’m considering changing my mind. Is there a huge difference in the sound quality between the two?

Asked by: Trap
The ARENA 130 is a great speaker that can handle an awful lot of power, up to 125 watts, and it sounds great. However, there is no arguing that the STUDIO 230 is a higher quality speakers. It can handle up to 150 watts of power and is made of higher quality components (woofer, tweeter, crossover). My personal opinion is, I like the sound of the STUDIO 230 a bit better. It has a more natural, full-range sound, to my ears.

I have studio 190 speakers. Can i use studio 230 and 235c with studio 190 speakers. Thanks.

Asked by: Serkanonde
100%. I have the Studio 190/180/130 speakers and recently "upgraded" if you will, to the 235c. It bends in perfectly with the other speakers in terms of sound and looks. In fact with the grill off it looks like it could be part of the 190 series. I am very, very happy with the 235c.

hi. looking at my pair of 230s am i right in thinking banana plugs wont fit ?

Asked by: jimmykeys
Hi Even though we cannot and do not recommend using banana plugs, it is possible to use them with the Studio series speakers. Remember to remove the plastic red and black inserts in the speaker inputs before attempting to plug in banana plugs.

Can these speakers be placed horizontal on a bookshelf instead of vertical as designed? It looks like the feet are not attached and could placed on the long side okay for a horizontal placement. Would placing on the side influence the sound in any way?

Asked by: KW3416
There would be little to no difference if you place the speaker sideways. Feel free to place the speaker however you want it to and make sure that there would be space to breathe at the back where the connectors are located.
