    • Alto Professional TS412 – Excellent Quality at a Great Price
Style: PA Speaker
The Alto Professional TS412 is an outstanding powered PA speaker that continues to uphold the brand’s reputation for delivering high-quality audio at an affordable price. Having used Alto products for years, I can confidently say this model is no exception. The sound quality is impressive, with clear highs, punchy mids, and powerful bass that can handle any event, whether it’s a small gig or a larger gathering. The 2500W output ensures plenty of power, and the built-in 3-channel mixer offers versatility for connecting multiple audio sources. Bluetooth streaming and wireless speaker linking are game-changers for ease of use, especially for modern setups. The DSP and the Alto app provide additional control to fine-tune the sound to perfection, making this speaker highly adaptable to different environments. For the price, the TS412 delivers exceptional value. It’s durable, reliable, and performs on par with more expensive competitors. If you’re looking for a speaker that combines quality, power, and affordability, this one is a fantastic choice. Pros: Impressive sound quality with clear highs and punchy bass 2500W output, providing plenty of power for events of various sizes Built-in 3-channel mixer for multiple audio source connections Bluetooth streaming and wireless speaker linking for added convenience DSP and Alto app offer easy sound customization Affordable price for the quality and features offered Cons: A bit bulky for some users, especially for smaller setups or transport Not the absolute loudest speaker in its class, but more than sufficient for most events The app setup can be a bit tricky for beginners ... show more

    • Really great speaker for the money!
Style: PA Speaker
I bought this speaker to replace a fried Mackie drum wedge at the venue I work for. I have QSC K.10.2’s for the rest of my wedges and of course they are spectacular. There just wasn’t money to purchase another QSC so I had to look for other less expensive options. We have another Alto speaker, a 400 watt 10” powered speaker we occasionally use as a personal monitor or an extra main source in a dead part of the room that always has sounded great. I decided to go with the 12” 2500 watt Alto instead of the 10”. It sounds really good as a drum wedge and has more than enough power and range to feed it both kick drum and bass without it clipping or distorting. The DSP is simple but useful. Not using it but the Bluetooth works great. The only thing that I noticed about the speaker is that the enclosure feels a bit thin in a couple places and really vibrates at high volume levels. It is not creating any audible vibrations however, no rattles or unwanted sounds.its been in the venue for 2 weeks now and performing wonderfully. I’ll be checking in again at 6 months and a year. Now with all of this said it feels really good, vocals are hot and clear with no exaggerated frequencies or feedback tendancies. It’s not a QSC k.12.2 but it was definitely engineered well and offers a great sounding alternative without breaking the bank. The controls feel very solid. The speaker also looks like it should have a higher price tag. Great job ALTO! So after a month of nightly use in the club as a drum wedge receiving the full band with high levels of vocals, rhythm guitars, keys, bass and kick drum the speaker has surpassed expectations. It handles bass and kick drum with no problem at all and it is more than loud enough to be considered an option if you don’t want to spend the extra on JBL EON’s, or QSC k.12.2’s. When set flat they are nice and balanced and music over BT couldn’t sound much better. There are also DJ, Wedge, and a programmable EQ that is accessible through ALTO’s iOS app. ... show more

    • I got to tell you, THESE are a GAME CHANGER!
Style: PA Speaker
I originally was going to pickup the new Mackie Thumps but, the price point against quality is astronomical. There has been another type of speaker on my mind for over 2 years (this company), and recently they came out with this new line that blows Mackie speakers right out of the water when it comes to clarity of sounds, and low end. I set these up when they arrived. All I have to say is OMG! They sound just as good if not better than most speakers at this price point! The bass is hard, and clear! Plenty of power that does not rob your vehicle of space when transporting! The speakers are about 33 pounds each. 3 handles, beautiful construction, high quality! Perfect for DJ's and/or bands looking to pack a punch! I'm considering picking up the smaller ones as they are even pretty high powered for more compact setups! Move over JBL, Mackie, and QSC! Alto Professional donesn't play! Also, I know the price is a little high for them but, get the protective covers for them! You'll thank me later! ... show more

    • Great speakers and the Bluetooth is a nice feature
Style: PA Speaker
Review Image by Christopher
Great for such an affordable speaker. I've used this set with several events and they have performed well every time. I wasn't sure how well they could actually perform outside, but they do not disappoint. I have now had the chance to use them several times for various crowds. Outside as a set for several hundred people worked great. Used just one speaker outside in a park for a community giveback, and with just one speaker I had plenty of power and volume for 100 people. I was told you could hear it clearly halfway through the apartment complete. Very impressed for the price. Looking at buying a second pair but smaller. I first found this brand back in 2014 and still have a pair of speakers that work great. The added Bluetooth on the new models is a great addition. You can even link the speakers together using Bluetooth, but that only works with Bluetooth signal, so if I have a wireless mic plugged into the speaker I have to run an XLR to the second. Wish the Bluetooth link between speakers would have been for all signals being sent to the speaker. ... show more
