[93 lb] It took me a few minutes to dial in the JBL, but once I figured that out it sounds smooth and complimented my setup perfectly. I'm not sure why anyone in a studio setting would want to use anything but the 80hz crossover. It had PLENTY of power, in fact, it's set to about 40 percent power to balance out with my studio monitors. Folks that say it doesn't have enough power need to turn down the gain of their monitors.

The whole idea of a studio sub is not to blow you away (which this can certainly do) but rather to compliment (extend the frequency range of) the monitors. It does this very well. If you don't use this balance, your mixes will not be accurate may result in them being low-frequency deprived.

I can easily switch between sub + crossovered monitors to monitors with no crossover with my Mackie 1642VLZ4 mixer. I just use a subgroup output to isolate my monitors without the sub. What makes this possible is that the HS8 monitors have 2 inputs, so your miles may vary.

When dialing your sub in, remember that less is more. I've found this to be true in just about every facet of life.

Happy Mixing.

[30 x 25 x 24"] Monitors by itself are good enough for small rooms, but if you have a bigger room, a sub is a must. It fills out the bottom frequencies and nicely rounds up the sound. Perfect for a 2.1 home cinema setup. Best matching seems to be with JBL LSR 305. If you have 308, the bass might become overpowering.

[93 lb] Added this in with my edit bay and I love it - everything is much fuller overall.

[Plywood] Only had it for a week did two gigs and love it. Very good sound quality

[93 lb] I work with a variety of clients who have vastly different Audio needs. I paired this sub with some LSR’s and have been very pleased. Whether it’s a singer/songwriter with an acoustic guitar and vocals or EDM/club music, this setup is very adaptable. Just give your speakers some space away from hard reflective surfaces and enjoy! One note - I wish there was a protective grille; it would just give me some piece of mind.

[128 dB (Peak)] It's a big one but paired with the 305s it works nicely. Placement is really important. Happy I waited for it to come on sale.

[93 lb] Purchased for personal use in my garage, sub compliments JBL speakers and produces really good quality.

[95 dB] Glad & very, very happy with this JBL 218s & it's Performance. I'm from the Islands T&T & playing my type & others of course, jus can't go wrong. You get the Ultimate Lows that you would expect from this JBL 18. Unit is all Black & Attractive. Ty B&H for directing me to get this Subwoofer. Plays with two JRX 225, also from B&H.. Best Sound System..

[128 dB (Peak)] Unpacked and connected, didn't have to adjust anything. Plugged my studio monitors to the outputs of the sub, then monitoring system out to the sub inputs, hit play and go. Sub has a higher wattage than most, higher price, but I waited until it was on sale. I did consider other active subwoofers, but this one has a larger woofer, and flexible in's and out's, and is tuned to match my JBL 5" studio nearfields. Great item!!

[30 x 25 x 24"] I bought this subwoofer from B&H on sale for $300 when originally its $500. I did research on it and when I used it, it works exactly as advertised. I am satisfied with this product and the way B&H works. No issue at all and use this subwoofer in all my sessions from recording vocals to making beats.
