JBL GX502 130MM. Buon prodotto, arrivato nei tempi previsti. La qualità audio è buona, i bassi sono potenti e riescono a scendere sorprendentemente bene di frequenza considerando che sono altoparlanti da 130mm, anche la gamma alta è buona anche se personalmente trovo la timbrica del suono un po' "metallica". Nel complesso un buon acquisto soprattutto se paragonate alle casse originali. MONTATE SU DACIA DUSTER senza particolari problemi anche se bisogna cambiare gli spinotti di attacco. Nel complesso soddisfatto. Read more

I can't believe the sound I am getting from a small speakers. My smart car dashboard speakers packed up so o need to replace them. I liked the reviews of these speakers. I am so glad I got them the sound is amazing I not have much base going through them but your be stupid to think you get good base out of a small speakers. The sound is crystal clear and the tweeters are great as well. Great buy Read more

I have the speakers running off of my aftermarket Kenwood head unit. They sound great for the money. Read more

My wife’s vehicle is the 2016 Acura MDX with the standard sound system: 1 Subwoofer in the back, 2 rear door speakers, 2 front door speakers, 2 tweeters at the pillar by the windshield and 1 center speaker at the center of the front dash. We have this vehicle for 4 years but I rarely drive it until a month ago, when my car was in the shop for a week. I noticed that the sound is decent when the vehicle is not moving but not too good with road noise and the clarity is gone. Setting the treble control (on the head unit) to more than 75% (of the range) only make it worst with too much treble. Crank up the bass control causes the sound muddy. I started listen with only the front, then the rear speakers. The volume of the rear speakers is lower than the front, mainly with mid and muddy bass. I removed 1 of them to inspect it and understood why. It is a full range speaker with the whole frame in plastic (yes, metal at all), the speaker is very light. I noticed the stamping on the frame indicates the impedance is 2 Ohm. With this information, I started searching for replacement speakers that can improve the sound, starting with the 2 rear speakers. My first place to shop for car’s speaker was Crutchfield. To my surprise, it doesn’t carry any 2 Ohm speakers. Since I keep the head unit, replacing the 2 Ohm stock speakers with 4 Ohm aftermarket will reduce the volume which reduces the bass. With the subwoofer is on the same signal line of the rear door speakers, I don’t know how it will behave if the impedance of the rear speakers changed. On the Crutchfield page, I found this 2 Ohm JBL speakers but according to the service rep, this model has been discontinued so I couldn’t order them. Not give up yet, I search on Amazon and find it still available here so I order 1 pair. Replacing the stock speakers is not too bad, the most difficult part is drilling 4 new holes into the metal of the doors so the JBL speakers and the plastic adapter plates (came with the speakers) can be mounted. I also ordered the wiring adapter so connecting the new speakers and the vehicle harness was a snap. After 1 new speaker was installed, I compared the new vs the stock speaker. The different was day and night. The new JBL produced clean high with tight bass and clear voice. The stock speaker was mostly upper bass and mid range, the overall sound was muddy. Another good thing was the volume remains the same between 2 speakers. After the 2nd new speaker was installed, I listened with the rear speakers only. The music was really gooooood (yes, it was that good). I slowly faded in the front speakers and the muddy sound started pouring in. I then compared the front speakers only and the new rear speakers and again, the different was day and night. I knew I need to replace the front door speakers so I ordered another pair. The wiring adapter I ordered came with 4 pairs so I can use the left over for the new front door speakers. Attached are the side by side pictures of the JBL and the stock speakers. Read more

ハイゼットトラックのドアは元々10cmスピーカー用の穴しか開いていないので、グラインダーとドリルでドア鉄板に穴拡大して取り付けました。中華製の10cm 200Wスピーカーをつけていましたがアンマリだったので取り替えました。 国産で同価格で再生周波数等 性能の高いものもありますが、その性能だけでは音を語れないのがオーディオの面白みであり、醍醐味です。 まさにJBLは性能以上の価値があります。低域、中域の厚みが増して、今までのスピーカーでは再現できなかった音が見えてきました。 これにはびっくり。いつも聞いてた音楽がまるで別物です。 かなりの方が満足する音を奏でてくれると思います。ダッシュボード上にもJBLホームオーディオ5.1CH用スピーカーをセッティングしておりJBL4スピーカーで毎日楽しんでおります。国産品と値段で迷ったらJBLを断然おすすめします。 Read more
