Alphasonik18" Flagship Series 3000 Watts Raw Sub Woofer Speaker Cast Aluminum Basket Driver for Pro Audio PA DJ Cabinets Replacement Subwoofer with High Power Extremely Clear and Loud - FW1832

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's5 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

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.

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.

I’m impressed,i needed to replace my blown altec lancing 418,but altec doesn’t make any more and a used 1 is 525.00 dollars,so shopped around for something made today and not 5hundred dollars just for the 15inch and not some cheap import “ want to be” speaker cuz they are many of those.Came across alpha f/s 15”,had good specs with a cast aluminum basket,not cheap little steel basket so I bought. Installed in 1 of my 5ft altec pro audio boxes and listened to it compared to the altec 418 and it hit harder & a little lower that’s y I’m impressed just at 59dollars each,I’m pushing them with a 5k watt NAD power amp,they sound great.Highly recommend

I took a leap into the world of alphasonik 18” flagship series 3000 watt speaker, and let me tell you it’s pure audio bliss! This powerhouse delivers a sonic experience that’s beyond satisfying. The deep bass and powerful sound make it a standout choice. Trust me, if you’re into jaw- dropping audio adventure, this speaker is the real deal !TikTok @rippleride

I was surprised with this sub. I usually use eminence, but this one performs just as well, and frankly, seems a little bit tighter of a response.

After playing for two hours, we start to smell burning smell wouldn’t you recommend them

Unbelievable is all I can say. I just tested this 18 out Saturday night. When I say I tested it, I mean I tested ran my Berenger 18' at 80hz and increasing the volume throughout the night, dropping heavy bass, money bagg yo, sexy red, 21 savage etc. Just barely red lining, this thing didn't drop a tear. Got one before I got the second, grabbing the second one now and will use the order as a backup.
