RockvilleRVW1800P8 1800W 18" Raw DJ Subwoofer 8 Ohm, High Power Handling, Deep Bass Response, Durable Build, for Professional DJs and Live Sound

Wow! Got myself two of these 8 ohms (4 ohm since I'm sharing into a single 500 watt dayton subwoofer amp. I built the boxes 4.5 cubic feet net SEALED with adequate bracing. The amp gain only has to be 1/4 way up, NO MORE. Use the DSP in your receiver to help balance out what needs to be. Wow! I got these to sound great with music as well as home theater! And yes! Plenty of push and vibration all the way down to 20hz! KID YOU NOT! This is because of their size and I have two of them. I went with sealed because I want the response to be quicker to make up for their cheapness and size, and it worked out nice! Best part too if one ever damages I wouldn't mind slapping $100 down for another, easy replacement!I've played with many SVS models, and I went DIY and hearing the results I don't feel like I'm missing much. Again, 100 bucks a pop!

The speaker works great, I am very satisfied.

I have four of these speakers and they worked okay

One of my Behringer B1800X sub drivers suddenly betrayed me, developing a heartbreaking open across the voice coil. The cost of a replacement coil was steep—$100 just for the part—and the process to replace the coil was daunting, filled with uncertainty. I knew that if I made a mistake, all my efforts might be for nothing. It felt like a gamble, a battle against time and money, and I was on the verge of losing hope.Then, a glimmer of temptation appeared in the form of an 18" Rockville. With rave reviews echoing like a chorus of reassurance, I felt a flicker of hope igniting inside me. For about the same price of a voice coil replacement, this seemingly perfect alternative beckoned—an opportunity to breathe new life into my beloved system. Risking it all, I took the plunge and purchased a "used-like new" Rockville subwoofer from a third-party vendor, spending less than $70. The product container was blemished, yes, but the subwoofer itself radiated that untouched, pristine quality—no signs of wear, no evidence of mounting. It was my first Rockville purchase, and I confess, I tend to be picky with my audio gear—trained to expect a certain pedigree, wary of disappointment. But the price was compelling enough to soften my stubborn standards, so I rolled the dice.When I held the Rockville in my hands, I was struck by how astonishingly similar it was to the Behringer. The basket and magnet—identical in every detail save for the basket color—made my heart pound with hope. Its weight felt equal, no difference by hand. The only physical differences I could see were the coating on the cone—something the Behringer lacked—and the Rockville surround with one less rib, though its ribs were slightly wider. The screw-down wire terminations on the Rockville were a nice touch, good quality too, whereas the Behringer had spade connections. Everything lined up perfectly—the mounting holes, the bolts—they fit flawlessly, as if it was meant to be. I required no enclosure modifications as the mounting holes lined up perfectly - which was critical as the Behringer enclosure has threaded tee nuts for the driver mount. The insertion and securing process was straightforward, almost effortless, reaffirming that I might just have found a true replacement.I was able to do an A/B test with another Behringer B1800X. By ear, I could only discern a slight efficiency difference with the Behringer being a bit more efficient, but it was easily correctable running a multi-sub setup. That being said, one could always get equal output levels adjusting sub amp input or output settings - but the amp will work slightly more to get it - but it is slight. Maybe I'll do some sweeps with a mic and REW to see if any other significant differences exist. I did not hear any other by ear. Low extension was similar, mid bass punch was comparable. Let's see if this thing will handle the rigors of Thursday night frat parties.Overall, for what I paid, this is a tremendous option. I'm satisfied with the quality and ecstatic with the value. This Rockville kept me from having to either attempt a repair for the same price or fork out hundreds replacing the entire subwoofer unit while still making use of a perfectly good enclosure. Highly recommended for a low price replacement for a failed subwoofer driver.

Not gonna lie but these things pound some clean bass👍🏼If you want clean, between 32hz-120hz bass and then get them. I have 4 and custom made enclosures, each pair ran on a crown 1502 amp and they have blown me away especially for the price!!! Sometimes the crown amps tend to clip a bit but these things love that power especially being clean power and run cool👍🏼 each sub is receiving about 400-475 rms and amp is running of course on bridge at 4ohms. These amps can give you a band pass filter which is awesome!! but i have them at 37.5hz to 125hz and they are more then happy to run all night so far not complaints and have used them about 12 times 5 hour edm and hiphop parties nonstop. Sound very similar to 2 jbl srx dual 18’s with the custom made boxes. highly recommended for a project!! Get a pair and feed it the right power and a good enclosure and you will not be disappointed.

They work well. Cant be beat for the price.Also, upon googling these speakers, i came across some DJ forums where members were asking if anyone had heard of these, followed by abundant nay saying by "brand name" guys automatically downing these as "no name" brand speakers. Well at the price, any half successful dj conducting venues should be able to painlessly afford to try these. I must say, I am VERY pleased at the performance of these drivers.Included were all necessary specs,(see pic) in case you would want to design your own enclosures. Anyone can drop names of brands that cost an arm and a leg, but let the product do the talking. I think these deserve a look by anyone interested in 18 inch high power handling drivers.

Once again people "MADE IN CHINA" normally garbage, but not always. Most name brands outsource to China unless you're talking top of the line. These hit pretty hard, good size magnet, put them in a transmission line box, the whole house shakes like crazy! Sounds clean driving it with the Behringer Inuke 6000. The amp was questionable itself but when I used my QSC RMX 2450 it kept popping the breaker. That amp actually can overpower this speaker. Anyways hits hard, sounds clean, you can tell it is a quality speaker. I have bad China, and good China. This is an example of the GOOD CHINA.

Subs are junk hooked them up blew one within the first 20 minutes, just blew the other March 21st and had no distortion.
