Question: Is this a single speaker or a pair of speakers?
Document: I bought a pair of these for my car and I absolutely love them! They have excellent sound quality and they can handle the low frequencies and not distort. They have a tweeter that you can adjust the decibels on. The speaker is built well and sounds even better. I am thinking about buying a second pair now.
I just put four of these in my 1999 Tahoe to replace my old factory door speakers. What a huge difference in sound quality. Very good sounding mids with a better capacity to handle bass than the old ones. Yes, they are sold as a pair!
Probably some of the best speakers I have ever had the pleasure of purchasing and installing for under $50 a pair. I was a big supporter of Pioneer products for many years, however after purchasing a set of TS-G1644R and comparing them directly against these, the pioneer's fall way short of being any sort of acceptable upgrade for a factory amplified system.
Great Quality! After replacing other speakers twice,,i always know i should have bought the JBL's. Well,,,i finally stepped up and bought this pair. I had to custom install them and mutilate the grates w/ my dremel tool to get them to fit. The funny raised crap on grilles will prevent them from being installed in a lot of places that regular speakers fit. It was a pain in the ass! Wow,,,so worth the trouble!
I blew out my factory JBL speakers from rockin a little too loud, so I set out to find something to replace them with. The factory speakers, just like every other car line, were insanely expensive. I came across these on AMAZON to replace my two front door speakers, and, I am so impressed, I just had to get a pair for the rear doors as well. THESE JBL'S ARE AWESOME.
Awesome speakers.Paid $34 for the pair; Bestbuy in Canada was $199 per pair. I put 4 of these in my B6 Audi A4. The install was not that easy because I had to custom fit them to the pre-existing baffles.The speakers sound quite nice, and even better now that I have used them for over a year. They are powered by a 4 channel JBL amp with new larger gauge wire.Be sure to take note that they are 2ohm.
Bought a pair of these for my vertically driven sound bar. They sound great and look even better. Several different mounting plates come with them.
My concerns were completely abated. I installed a pair of the JBL's in the rear doors of my 2002 Dodge Durango and I am very impressed with their ability to handle the low end (bass) with absolutely no distortion. The mid-range is nice and crisp. To my ear, the JBL's performance is superior to the stock Infinity's, at half the price (the Infinitys are 50 bucks a piece!).
I'm a happy camper till my next upgrade. I recommend this speaker for anyone wanting to replace their Bose speakers on a budget.
These speakers have excellent high ends. The bass is better as well because of the extra surface area. I believe it would increase the low end if it were in some sort of enclosre instead of using the entire trunk space. Just an observation. Great speaker for the money.
Answer: A pair but keep in mind these are full of bass sometimes took over the highs
