I just came across these, what brand and models are their main competition? Are they to compete with JBL PRX?
null on Oct 24, 2011
BEST ANSWER: I would say that the JBL PRX has the edge due to their build, and wattage and amplifier quality. For more information on the PRX series call 1800-268-5520.
Why it doesn't sound right when I use my phone to play music,?
A shopper on Feb 27, 2016
BEST ANSWER: As in all audio, source is everything. Depending on your particular phone or the cable you are using to go from phone to speaker, you may only be getting half the signal. If you are getting only music and little to no vocal, or heavy vocal and little to no music, this is likely what is wrong. Beyond that, most other issues can be overcome by manipulating the settings on phone or speaker.
How many ohms does each speaker have?
Mike on Apr 2, 2015
BEST ANSWER: The Alto TS115A is an active speaker, meaning that it has no effect on the Ohm load of a passive speaker system. You would connect this before the amp in your signal chain if using this along with passive speakers.
Hi is it possible to use the Alto TS115A Active PA Speakers as a passive speakers.

thank you.
echot on Feb 21, 2015
BEST ANSWER: The only way to use the Alto TS115A as a passive speaker would be to open up the cabinet and remove the amp inside it. I wouldn't recommend it.
Can I purchase a warranty with the re-manufactured TS115A?
Brick on Feb 12, 2015
BEST ANSWER: Yes, you certainly can purchase a warranty to protect your TS115A, and given the shortened manufacturer's warranty on the refurbished model, we highly recommend it!
Does the (Used) Alto Truesonic TS115A come with XLR cables?
Mike on Feb 12, 2015
BEST ANSWER: No, all products on our website come with just the power cable unless specified otherwise.
What is the Output Power Wattage?
Ed M on Jan 2, 2015
BEST ANSWER: 800 watts peak power
What is your experience with the reliability of the TS115A?

I've read some pro reviews of the TS115A that were extremely favorable, but it seems like there are lot of people complaining about reliability.

I looked over the customer reviews at Guitar Center and Amazon and there were an awful lot of people (about 25%) that have had problems with them, mostly with the woofer end.

I know there a lot of idiots out there, but I'm not seeing similar complaints about the TS112A. In fact, *none* of the reviews of the TS112A complained about them failing.

I'm looking to use these for a small (fairly quiet) band for backyard parties and rehearsals, maybe for open mic night at our church social hall and some karaoke. I think that is the kind of thing the TS115As should be well suited for, but I'm worried they won't hold up.

Is there something else near this price range that you think might be more reliable? Do you think the TS112As would be a good choice instead?

Mark on Nov 3, 2014
BEST ANSWER: Given your application, I don't foresee you encountering any problems with the woofer. My regular client for these are DJs who love to push their systems and I don't get returns or complaints fairly often on these. If you are concerned about the unit's lifespan, we do offer 2 and 4 year warranty extensions to make sure you're covered even longer.
Im thinking of buying some of these, just need to know if they come with a warranty? If so, how long? Thanks.
Joe on Feb 2, 2014
BEST ANSWER: Great question! Since these have been reconditioned by the manufacturer, they carry a 1 Year warranty to provide peace of mind on your investment! Additionally, PSSL can offer Extended Warranty Protection that will cover an additonal 2 or 4 years--you have the potential of having 5 years of protection on these speakers!
What exactly is meant by reconditioned or used equipment?
DJ Malarky on Jan 22, 2014
BEST ANSWER: Thanks for reaching out to us to get your question answered! Any items sold by PSSL as having been reconditioned have been inspected by the manufacturer and any concerns have been addressed. The equipment is expected to be in as-good-as-new condition. In many cases, the original warranty even applies.
Hi, im planning to use this speakers on a country that has 220v ac power source. It says at the back of the unit AC POWER 110V or 110V- 220V AC or 220V -240V AC, can i plug this directly on a 220v ac sourc or do i need to change the fuse rating first or use a transformer? your answer is greatly appreciated-thank you
Reggie on Feb 21, 2013
BEST ANSWER: From that listing, it seems that you should be able to plug directly into a 220.
what fuse rating should i use in the iec mains cable?
null on May 27, 2012
BEST ANSWER: That is more a tech question. Please feel free to give us a call at 1-800-945-9300.

Product doesn't last long!
Pros: Attractive Design,Easy To Set Up,Easy to Mount,Great Sound Quality,Good Power Output

Everything people say about this product is true!
But people are rating the product, The day they used it or here them for the first time..
What people are leaving out is that the speakers are not built to last long.
If your a Dj who does more than 3 gigs a month these speakers are not for you.
They are not durable, they are priced cheap, so they are made cheap!
Over 100 or more speakers have shipped back to the factory for repairs. My alto speakers included. It's been there for over 2 months. Still have got them back!
I called the company regarding my speakers? They said they don't have the parts to fix my speakers until late August! This company sucks! A friend of mind bought the same speakers and his went out! Sounds good, priced good, but doesn't last long!
Save the headache and stress! Buy another brand this is a waste of time!!

Best Powered Speaker
Pros: Easy To Set Up,Great Sound Quality,Good Power Output,Attractive Design,Easy to Mount

As a mobile DJ I wanted something very loud and clear with very nice bass in a light weight cabinet. These speakers deliver all that and then some. I did a side by side test with several of the more popular brands including some very exspensive speakers and bang for buck these just cant be beat in my opinion. And the opinions of the other people who were at the test site. If you are a mobile jock, please look into buying these speakers and Im sure you will be very happy.

Good Speaker With Upgrades
Pros: Attractive Design,Easy to Mount,Good Power Output,Great Sound Quality
Cons: Weak Woofer For Amp

I have to say that Alto was not my first choice for speakers. We tried them and they sounded much better in the Mids over the Thumps. Yes, these units failed the first 2-3 uses. The woofers blow and warranty was a mess. We ended up upgrading the woofers to Kappa Pro's and had these units running over 2 years with no problems! Amp and Driver are great, Woofer = UPGRADE!

ALTO TS115a's / TS112a's ROCK!
Pros: Easy to Mount,Easy To Set Up,Great Sound Quality,Attractive Design,Good Power Output
Cons: Keep The Gain Low

As soon as I used these, I knew I needed to get more. That was 3 months ago. Now I have another pair, and a pair of the TS122a's, being EQ'd thru an ALTO AEQ215.

My next wishlist item will be a pair of the TSSUB18's to complete this system, and maybe an additional set of TS112a's because I fly the sets of the 15's stacked as a pair for mains, and the 12's on stage for monitors. Another set of 12's for monitors will round it out.

I am very happy with the ALTO lineup COST vs QUALITY

Solid speaker.
Pros: Attractive Design,Easy to Mount,Good Power Output,Easy To Set Up,Good Construction Nice S
Cons: Stability At High Output

For the money this is a good speaker. The sound & build quality is good but not great. Do not push these hard. Dont expect a lot of bass. They are good for small venues.
