2,500 Watts Can't Get Any Lighter

Possessing the same desirable functionality as Alto Professional's TS3 series speakers, and boasting some favorable upgrades, TS4 Series speakers provide stage-ready performance that's easy to integrate into any setting. A whopping 2,500 watts of power generates a truly authoritative output, which can be controlled entirely via EQ control and from Alto's free smartphone app. TS4 speakers also come with True Wireless Bluetooth linking capabilities, providing a smooth, seamless connection between devices whenever and wherever you may need it. Sweetwater sound professionals are always looking for versatile speakers to bring to their next gig; given the TS4 Series speaker's lightweight build, there's always a surplus of them on standby.

Additionally, a 3-channel EQ mixer and controls via the free Alto app provide an easy way to swap out configurations, letting you shift your frequencies and characteristics to grant the perfect sound at any gig. Best of all, TS4 Series speakers — although jam-packed with functionality — are incredibly lightweight, making them a cinch to travel from session to stage.

altos ts 412

Ok first let's start with room size 10x14 but entire house 2000 sq. and I hear them in the entire house and in my back yard no problem. 2nd delivery ordered Wednesday got it Friday after noon. ok now the good stuff Hehe I upgraded from Rockville rpg 15 tops I got them them 5 years ago they was true 250 watts rms. well now I picked up the alto ts412 and a alto 212s sub 12 inches but it all together with a sound exciter and a Pyle pmx7bu. now what I use my set up for. before people start to criticize. I am no Dj and don't plan to be. I use this with a tablet to stream my music nothing more. so for me this is plenty now. will talk about system the alto ts 412 sound amazing clear solid and punchy loud sound. do I think it's 1250 rms no I would say the woofer is about 400 t0 450 rms as for the lows for highs I don't" know had a few systems just talking about 2 here only but anyway back to the altos ts 412 these would work well in a small venue or mid venue no problem whatsoever. Do I think they worth the money as of this review yes would. I buy again yes as for longevity I just got them so they just a day old only time will tell. one thing I do know this is the first pa powered speaker that I could bring up volume pass half way with no clipping. I can take it up to 9 clock with out clipping. as for the app nothing special I could do everything from back of speaker. setting up tops and sub some advise save you the trouble and time and will sound great plug tops into sub. don't go from sub out to tops will not sound good and may not benefit from all the power. but do what you like you pay for your set. as for me i tried both set up. and for me tops out to the sub sound way better and lots of power. do I recommend them oh yes I do. will not regret. I do't get pay to do reviews but I was very happy with this and felt it was worth my time. save you money on Ev or what ever els is expensive all the same trust me I worked for a corporation. all they do is swap name and outer cabin of items we even sold the rights to use our brand on other speaker that was not ours. don't get me wrong if you spend 4 or 5 thousand yes you will get something way better but for $ or $ bucks more you paying for the brand. at the end all made in China. lol

hands down the best for dj, band or solo gig
to the person who's replaced 5 tweeters in theirs, I call total bullsh*t.... thats definitely operator error. Ive have several sets of these and have literally had zero issues.
Wow
I read a lot of reviews to find what I needed. I'm in a band that plays small to medium size venues. I wanted enough power for outdoor events as well. Another guy in the band got Alto TS12S subwoofers. We put them together outside and put them through the paces. I couldn't be happier with the sound quality, plenty loud and crystal clear, with plenty of headroom to go even louder. Thanks go out to my sales engineer, Jeremy Kaiser, for helping me out with another purchase from Sweetwater. When it's time for my next big purchase, probably a Helix Stadium, I will reach out to him again.

Love these.. Comparable to Mackie Thump
Love these... just as powerful as my Mackie Thunps, but much more clarity on the high end. I own both the 10 & 12 inch in this series. Skip the covers and buy cases, you will be much happier if you move around alot from gig to gig.

Works great for church in the park.
We bought set of these speakers to use for Church in the Park.
They work great. We bought two 25' XLR cables made by Gator and you can put a different color one each end which works great to know which one is going to which speaker. Just wished I had bought longer XLR cable. Will probably get one 50' XLR.
