ESP Sound has been our exclusive sound company since 2006. Paul’s expertise is extraordinary when it comes to finding the perfect mix for our band. Trust us, It’s not an easy thing to do with 5 to 6, live, open microphones onstage along with five instruments and with 4 separate monitor mixes. Whether it’s a club, small corporate event, large wedding or mega large indoor/outdoor festival or venue, ESP can adjust, adapt and make us sound incredible wherever we are. Bottom line is, You can have the greatest band/sound anywhere but the real truth is, if you have bad sound, it doesn’t matter how good you are. You’ll just sound bad. Paul Duffley and ESP Sound, understand and know how deliver our sound to the audience. You’re as good as your sound company and Paul is great! They also go above and beyond in several other areas. If they are busy (as they always are) they secure the best alternative sound for us through there vast network of sound professionals. We could go on as they do so much more. So if you’re looking for the right sound company, look no further. We couldn’t give a higher recommendation to Paul Duffley and ESP Sound.

Over the last three years I have worked with ESP Sound system’s entire staff in a wide range of music venues, less than ideal situations and huge concerts. Paul, Dave & Tim have always gone above and beyond the call of duty working with the artists to get the sound they want, the venue to get the volume they want and all my staff in running a successful event. Three years ago I worked with four different sound companies and now I only work with one, ESP. The others didn’t go out of business, charge too much or do anything wrong – they just didn’t get it like ESP did and does. Whatever your needs are from an acoustic session to an area, ESP will satisfy.

Paul, I want to thank you for the incredible job you and your team at ESP Sound did AGAIN this year at the 10th Annual South Boston Street Festival! I can only imagine the challenge it must be to provide sound for two stages simultaneously for such a wide range of musical acts – in such a short time period, with just moments for sound checks. Many of our performers commented on how good the sound was, the quality of the sound systems and the expertise of the team. Great job! Thanks Again.

I use ESP for all my shows and would not think of using any other company. I always receive positive comments from the Audience and the Artist. It’s a great feeling when you have a sound team that is so professional that you do not have to worry about one of the most important parts of the show! (My last artist wanted ESP to travel with them around the globe!)

For the last 5 years, Paul Duffley has provided exceptional sound and service to the Town of Watertown for the annual “Faire On The Square”. We have been very pleased with Paul’s ability to provide sound for multiple stages, and work with a wide range of entertainers. I would highly recommend Paul and ESP Sound Systems for consistent reliable service. Of all the vendors I contract I am most at ease knowing Paul will handle the sound.

We have dealt with sound companies for shows across at least four states. And ESP has been one of the most professional and impressive companies that we have ever dealt with. After the very first show that they ever did for us, Paul and Dave knew our band’s sound better than we did. They will continue to be our #1 choice for big sound venues.
~ Thomas Brooks

ESP is my go-to Sound Company for medium sized events. On Time and Under Priced, Duffley brothers do it right.
~ Johnny Wiz

From our end, with the number of details that go into creating an event space for 3000 people on a beach parking lot, knowing you and your staff would be there providing great sound and service made working with you a no-brainer. Very easy from start to finish.

Paul and ESP Sound Systems have done a fantastic job for our band ”First Class Band” at many of our prestigious venues and special events. Their equipment sounds rich and full and their crew is a pleasure to work with. We are a very high energy ”dance band” and the sound amplification has to be right to make the crowd dance and let me say the dance floor was packed each time we hired ESP. I recommend ESP Sound Systems to anyone who is looking for a great sound, done by pros.
