## Description

The chill finally crawls from off of your spine. For a moment there are no words that can describe the gut-wrenching bass tones you just heard. The next moment, you can't stop thinking of new ways to let the world know of your experience. You've just been exposed to an Alphasonik Flagship super woofer, and you won't soon forget the experience. These subwoofers are an industry standard for those looking to make bass tones once thought unheard stand out right in your face and make their presence known. Whether you are building your own speaker cabinet or replacing an old subwoofer, the Alphasonik Flagship woofer speakers are what you need! These Flagship models are great woofers that produce awesome tones with punchy lows. With ratings ranging from 400W RMS all the way up to 1500W RMS depending on the size you choose, this speaker driver can handle what most high power amps can throw at it. The Alphasonik brand was designed to make any musician of any caliber or a DJ sound great. All of our Flagship series subwoofers use our environmentally treated non-pressed paper cone - the most natural sounding material in the industry. Our paper cones reduce distortion when needed at lower frequency levels. This series also incorporates an extremely durable poly-cotton spider that is resilient from fatigue while still having robust response rates. The new Flagship driver series represents a milestone in high-powered subwoofers design. With its incredibly high RMS rating and extra-long cone excursion, Flagship woofers drivers provide maximum amounts of amazingly clean, deep bass. The Flagship is a superior choice for the low frequency sound of any high-powered sound system, from DJ rigs to the largest professional touring shows. The designs and engineering of these powerful drivers are ideal for instrument amplification and high portability applications such as DJ and small touring bands. Feel the bass of the next generation!

Review: Badass sub in a good way well worth the money.... - Okay I'm a DJ and I was looking for a good sub at a reasonable price.. boy did I make the right choice. This speaker hit so hard and so low that I get goosebumps.. sometimes I turn down the mids and highs just to hear the bass I'm a low-key bass head..lol I bought this speaker to replace my Peavey 18 inch sub.. now I'm looking for another box so I can buy another speaker and have twice the bass..... Update a year later .. So I add another sub to the system. And boy boy boy still a great sub... Don't sleep on it this is really awesome so I love the low's 5 years later subs are still going hard Now I just need to put them in two new boxes.. I might try to get something made.. You won't be disappointed
Review: Very disapointed - I bought this to replace an extremely old Carvin sub that had literaly dry rotted. Installed the sub in the box and started breaking it in with low volume. I was running it crossed over from 30 to 120hz with a behringer Inuke nu3000DSP amp. My signal is clean and all of my gains on my sources and mixer and crossover and amp are tweaked with an osc scope. Even at unity on my mixer{almost wide open} Itis set so there is 0 clipping and an average of close to 600 RMS watts going to the sub. With that said, During break in I was blown away. The sound of this thing was incredible.Clean deep punchy bass and very powerful sounding. I actually turned the gain down a bit more because it was a bit much for my 15 inch tops. After a break in period I fed them a little more volume and was even more impressed.The amount of air this thing was moving and the sound quality was beyond belief. Skip ahead a month.I had never even turned them up to the max levels I had set when I started getting a popping sound on deep bass notes. Iwasnt giving it any where near its rated power and it was a clean signal with no clipping. Luckily because of covid i wasnt out doing a dj gig with it.Over 50 year old fairly knowledgable sound guy here. I have to say stay away from this one. Sounded good but it should have never blown with the low volume and clean power it was getting.

### ⭐⭐⭐⭐⭐ Great Replacements
*by E***C on January 1, 2024*

I've used 3 of these for replacements in a Yamaha 218 cabinets. They work very well with this cabinet, and they easily out gun the stock Yamahas in both sound quality and strength. Each speaker sees around 2K watts regularly, no problem. They are still strong living a hard life 2 years and many shows later. I'll use these any time I need a replacement.
