It is amazing what hard work, patience, and the genuine desire to treat customers the way we want to be treated will result in! Just like the song from the TV show “The Jeffersons” used to say…looks like we are “Movin On Up”!! As you all know, we sell our products on Amazon.com. It helped us to get where we are today. We are in constant contact with our rep from Amazon, giving and receiving feedback and always looking for ways to improve through Amazon Services.
We received a call from them yesterday and they gave us a link to go to. What we found on the other end of the link was both humbling and exciting for us at the same time. Amazon decided to feature us as one of their Seller Success Stories. We were floored. We have always strived to grow the business. I guess you are never really prepared for the day you finally get world-wide recognition from Amazon. Here is a link to the story: http://www.amazonservices.com/content/case-studies-seismic-audio.htm?ld=AS
You guys know we are not the kind to pat ourselves on the back or anything like that. We are just regular guys trying to make good on our business model of providing musicians the most cost effective and high quality Pro Audio products on the market today! We believe that all musicians should sound their best, without breaking the bank to do so!
We encourage you to take a look at this article written by Amazon on Seismic Audio Speakers.

One thing we have always taken a lot of pride in is our dedication to our customers. We have never wanted to be just another corporate entity that treats their customers like a number. If it were not for you guys, we would not be here, period. It doesn’t matter if it means staying on the phone with you to ensure you get exactly what you are looking for, or our guarantee that we will be here to answer any tech questions you have. Many of you know us by name and have built relationships with us over the years. We would like to return that favor by allowing you to get to know us more personally and how we came to be in the pro audio and music industries. We are not all musicians. but if you get us in our cars or in the shower, we are all Rock Stars at heart. Allow us to introduce ourselves…the guys behind Seismic Audio.

I have often been asked about my relationship with music and the speaker industry. My usual response is that it was by chance. I enjoy music, but the other guys around here are the one’s who have all the passion for music. The next question is usually that I must share the passion on some level, otherwise why would I work in an industry that I am not passionate about. Honestly, I am still shocked that I wound up here because I previously worked in the food industry for 16 years. Then, I lost my job. It is funny, you see all the unemployment statistics in the newspaper and news, and you don’t think it is ever going to be you. Suddenly, there I was. Unemployed, wife, and two kids at home. It was scary. Wondering what you are going to do and how big of a step down I would have to take.
My friend, Steve called me out of the blue with what I thought was a crazy idea. He offered me a job on a trial basis. He then explained to me the entire history of Seismic Audio and the direction it was going. Details of how much the company had grown and the things he had in mind going forward. I thought it was crazy. The idea of him being willing to bring in someone who knew essentially nothing about Pro Audio.
It has been an amazing experience, It has been like a dream. And it came at a time when I desperately needed a dream…so I guess you could say that music saved my life.

Why is my PA Speaker not working?
This is one of the most common questions fielded by our Technical guys during the day! Of course there are many possible reasons why, but one of the first avenues of investigation should be to check your speaker to see if you have blown it. We understand that calling in and speaking with someone in tech support can sometimes be a hassle. Therefore, we wanted to publish a quick step by step tutorial of how you can check it yourself and confirm or eliminate this as the problem.
1. These first thing you will need to do is to carefully remove the speaker from the cabinet and inspect the spider to verify that it is connected to the basket contiguously with no separation. (The spider is the suspension between the back of the cone and the basket, right above the magnet).
2. Next, you will need to place a finger and a thumb from each hand around the dust cover in the center of the cone on the front of the speaker. Press down lightly! Allow the voice coil to move down with the pressure, just a quarter of an inch or so, and then rebound with no pressure. This movement should be smooth without any noticeable interference between the moving parts. If you hear any noise other than air movement, then there is reason for concern.
3. The third and final test involves the use of a 9 volt battery. Obtain a 9 volt battery. The terminals on the 9 volt battery line up with the terminals on the back of the speaker. Touch the terminals on the battery to the terminals on the speaker. The speaker should move at least 1/8″ . If it does move without any ‘scrubbing’ noise, the speaker is good. If it does not move or does move accompanied by a ‘scrubbing’ noise, then you have a blown speaker.
This is the most effective and quickest way to tell whether or not an audio event has caused your speaker to blow. Again, it is one of the most common questions we take in the Seismic Audio Speakers tech department. We thought maybe you all would find it useful in the event you were having issues with your PA speakers. As always, we welcome you to call us and we will do anything to help you and get you the sound you want.

So, you got yourself a great pair of Seismic Audio Dual 15″ Pro Audio PA / DJ Speakers. You also have great amplifier to power those speakers. You are ready to get out there and start rockin’ the house! There is just one problem – you don’t know how to hook the speakers to the power amp.
The most important place to start is at the amplifier itself. It is extremely important to make sure that amp is capable of handling the impedance (ohm) load from your speakers. For this blog, we are going to assume that you are using 1 channel of your amp and have a single pair of identical speakers and want to run in mono mode. Other configurations will be addressed in future blog entries. Most of the time, when running a PA in this mode, your speakers are going to be daisy chained (or run parallel). You daisy chain speakers by hooking one speaker up to an amplifier and then out of that speaker you hook up another speaker. Keeping in mind that for this example we have only 2 speakers with the same impedance rating, when you daisy chain speakers you divide the impedance. (For example, two 4-ohm speakers connected in parallel result in a 2-ohm overall impedance.) This is why it is important to be sure your amplifier is capable of handling the ohm load. If the ohm load of your speakers is lower than what your amplifier can handle, you will most likely cause severe damage to you amplifier! (And most of the time – void your warranty!)
Now, let’s go back to your pair of Seismic Audio Dual 15″ Pro Audio PA / DJ Speakers (SA-155T) for an example. Individually these speakers run at 4-ohms a piece. When you hook them up parallel (daisy chained), the ohm load of the speakers is 2-ohms. Remember, running your speakers parallel divides the impedance. A large majority of amplifiers can handle 2-ohms per channel (running non-bridged mode) – but it is important that you check your amplifier and find out! So, if your amp can handle 2-ohms per channel, you are ready to hook up the SA-115T because daisy chained together they carry a 2-ohm load.
Let’s say you got the same 2-ohm per channel amp, but you have a pair of speakers with a higher ohm load. So, you have two 8-ohm speakers and when you hook them up is parallel they would be a load of 4-ohms. Can you do this? Yes, as long as the ohm load is not lower than the amp is capable of handling then you are okay.
But what if you have an amp that is 4-ohms per channel and the SA-155Ts which run at 2-ohms parallel? Well, you guessed it – DO NOT DO IT! If you run this configuration, you will more than likely severally damage your amplifier!
This is just a general example and there are many ways to configure running your speakers to an amplifier. What I am trying to point out is the fact that you should NEVER run an ohm load lower than your amp is capable of handling. This can permanently destroy your amplifier!
Now that you have figured out that your amplifier can handle the ohm load of your speakers, you are ready to get them hooked up! The last step is actually connecting the speakers to the amplifier. You need to find out what kind of connectors your amplifier and your speakers use. Some might only offer binding post connectors in which you would use banana plugs. Others might have inputs for 1/4″ connectors or speakon connectors. What is the difference in these connectors? In the context of this blog entry, it is just the connector itself. When applicable, I prefer to use speakon connectors because they lock in place and you know that you have a great, secure connection. Also, when the stage is crowded, speakon connectors insure that no one is going to accidentally step on a cable and pull it out of the speaker. Another thing to keep in mind when buying a speaker cable, the heavier gauge wire you use, the better. Heavier gauge wire insure that you are getting less resistance from the wire and therefore, less signal loss. Keep in mind that the lower the gauge number of the wire, the heavier the wire, i.e. 14 gauge is heavier or thicker than 16 gauge. The size of the wire is really dependent upon the amount of power you are pushing through it and the distance of the run. The details of that are beyond the scope of this blog entry though. Just be sure to use speaker cables and not instrument cables!
Well, you got the correct amplifier, a great set of speakers, and all the proper cables. All that is left is to hook up the speakers and to power up the amplifier. To daisy chain the speakers just plug in a speaker cable into the output of the proper channel of the amp and run it one of your speakers. Once you have put that cable into the input of the speaker, grab another cable and go from that speaker to your other speaker. Now you are ready to start the gig and to bring down the house!

These are very common question we get: What size amplifier do I need? What amp will work with these speakers? How many amplifiers do I need?
A good rule of thumb to start with is to pick a power amplifier that can deliver twice the power of the speaker’s continuous power rating. For example, let’s look at Seismic Audio’s SA-155T (Dual 15″ Pro Audio PA/DJ Speaker Cabinets) which have a power rating of 700 watts RMS. So, according to the rule of thumb, to power these speakers we would need an amplifier that can produce 1400 watts. Another important thing to take in consideration is impedance of the speaker. (The Ohms at which the speaker runs.) Now, let’s go back to our SA-155T example. The SA-155T have an impedance of 4 Ohms and, therefore, we would need an amplifier that can produce 1400 watts into a 4 Ohm load. Using twice as much power as the speaker’s continuous power rating insures that you are getting a clear and undistorted sound to your speakers.
You don’t have to run 500 watts through a speaker just because it can handle that much. If, for whatever reason, you have to use an amplifier with less power than your speaker, be sure to use caution. If your amp is being driven into clipping, this could really damage your speakers. Use your ears! If you can hear that your speakers are distorting, crackling, or popping, you need to turn it down! Just because your amplifier can put out 200 watts doesn’t mean you should run it at 200 watts.
