Sonic dynastyfused 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.

Studio 230 is rated 5.0 out of 5 by 26.
Rated 5 out of 5 by from It's what the Pro's Use ! As a veteran Recording Artist I can say this... Studio 230's are "true studio monitors". Moreover, every commercial Cinema uses horn loaded speakers for the mains & surrounds. These are horn loaded speakers. Is it any wonder that your local Cinema has JBL horn loaded 2 way speakers as surrounds hung along the sides & rear walls? Now, we can too. If budget allows? 7 of these puppies used in a 7.1 surround setup in your home, would be unbeatable! Especially if, you were to add a "worthy" sub-woofer to the mix. Studio 230's truly are 1 of the greatest 2 way speakers ever made for under $500. ~ peace

Rated 5 out of 5 by from Best price and best performing for home theater Had many options but went with Zeos Youtube review on these and took a chance. Loved how sturdy and big they are and they fit beautifully on stands as fronts in my 7.1 surround system.They sound great with a clean, non harsh tweeter and great bass.

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
i have found these dpeakers sound best close to the floor rather than ear height,with the grills off.. i bought 30 inch stands and after hearing them on them put them back on 12 inch little tables.theres so comparison in my room !!

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.

How would these fare outdoors on short stands with about 100 watts per channel?

Asked by: def38
The Studio 230 are designed indoors and are not made to resist humidity, while it can handle 100 watts per channel just fine. It may not last long outdoors due to a different environment .
