JimboSpins's review"Go JBL"

The JBL Pro JRX 125 is a pair of speaker cabinets that I purchased years ago for under 1000 dollars. They still look brand new and sound exactly the same as they did the day that I purchased them years ago. I have used many JBL speaker cabinets before and I know that most all of JBL products are built to last a long time. These cabinets are built with JBL’s best drivers and crossovers. They have steel grilles and are covered with carpet material to keep them scratch proof. Each speaker does have handles on them (built into the unit).
The frequency range is 38Hz to 16 kHz with a peak capacity of 1000 watts and 500 watts of continuous power. These speakers do get loud though and have a crystal clear sound. I originally purchased a pair of these back in 2007 for some shows that we had going at the time and I was not sure if I was going to keep them because I thought that I was going to need more power but they ended up staying apart of our gear all the way up to this day and I would not think about getting rid of them because they have a great sound and the tonal quality they provide for certain instruments like guitars is second to none.
For the money, you will not get a better sounding speaker in that range. These speakers are pretty heavy but for the quality of sound you will get it is well worth the back ache of carrying them around with you. These speakers are the true reason why I love JBL speakers so much. They are made with the best materials and have the best sound (in this price range). I would purchase these again any day, even if they were made years ago I still think they have held their value well!

Audiofanzine FR's review

- How long have you been using it?
I've been using it for one year.

- Which feature do you like the most / the least?
Output power
All in one (half three-voices speaker)

Weight (you'll break your back if you try to carry it alone. Not designed to be transported by one person)
High frequencies (imprecise highs. No details)
Mid frequencies (where are they?... Stop dreaming: the 15" speakers produce only low frequencies)
No protection corners

- Did you try any other models before buying it?
An Electro-Voice speaker that was over 20 years old
Hi-fi speakers (B&W, Infinity, Technics, ...)
Mackie SRM450 (V1)

- How would you rate its value for money?
Very good All in one. Very low price. The quality is on the same level as the price. The cabinet's wood is a bit fragile. No corners. Cloth covering tends to come off. Nevertheless, the product is ok for mobile disco applications!

- Based on your experience, would you buy this product again?
If I could choose again, I would buy a pair of JRX 115 plus a subwoofer. Do take the weight into account!!!

- Other
The speaker is ok for dance music. For vocal reinforcement, choose another product!
I use them as P.A. in bars, dance shows in sport halls or birthday parties. They work very well for these applications! However, the JRX 115 is a better choice if you want to fly the system!
I replaced the tweeter with an EV driver. An active crossover would be better to get a really good sound.

Considering the price, this speaker has punch!

A childhood dream come true ....
Continuous power: 1000W
Peak Power: 2000W
Impedance: 4 Ohm
Frequency response: 45 Hz-16 kHz
Max SPL: 133 dB !!!
Weight 43 kg

The filter for the crossover, is announced by JBL to 2kHz, so equalization was set accordingly.

JRX 125 ... I listen for two days ... full break!
What I like most is the accuracy of these speakers.
I bcp ecouté other speakers auditoriums shops ... The value for money is excellent,
€ 438 enclosure is cheap for the quality of the global.
Yes, I would do this choice if need another pair of JRX 125.

Personally I do not find that acute crachouille the contrary they are of a rather high accuracy (Titanium + ferrofluid cooled).

This enclosure class requires impeccable source and quality (to proscribe mp3 ...) and suitable amplification,
so that equalizer (mandatory for such power!).
Personally, my source they are Pioneer CDJ 200 + table Numark 5000 fx connected XLR output on a digital equalizer Behringer DEQ 1024,
that even plugged it into an amp Peavey PV 2600 and all with cables Monster Cable brand (+ modulation Speakon XLR / XLR + RCA / RCA).

Frankly, after a quick adjustment of the equalizer ... it rocks !!! lol

-> Specific treble, a clear and present medium, high and low (but not too much).

For lovers of the infra and low looking for grazing the resonant frequencies 45Hz ....
add to these JBL JRX 125 two subwoofers HK Audio (46 cm) + a second PV 2600 amp filtered 150 Hz max ... and there is a beautiful set reaches sono Pro allows you to add sound 500 to 800 persons fingers in the nose!

In summary, buy JBL JRX 125 eyes closed, no problemo.
By prévoyer against the budget (important) for quality cabling ... because it is a necessary condition for a good final result.
Do not hesitate to take the 4x4 mm² for speaker wire in Speakon NL-4.
Personally, 400 Euros cables (Speakon / Speakon + modulation XLR / XLR + RCA / RCA modulation), it hurts me somewhere ... but hey, I'm a purist ...

The only problem with these speakers ... weight ... 43 Kg per speaker! Devil to buy emergency !!!!!

10/10 I put these speakers because for that price in other brands there really of crap ....
The sound system at this price, go ahead, go to your nearest dealer!
