GSG Audio Design - South Gate, California

I can’t say enough good about Kevin and the GSG team. They have been key in the diy audio 🔈🔈community for years. Kevin is super knowledgeable, and his customer service is even better. If you want the baddest and biggest subs around. They are the folks to talk to. Thanks again Kevin for the low end of my end game setup.

GSG Audio is a great company and I'm glad I chose to buy from them. The owner, Kevin was in contact with me multiple times and answered all of my questions through the process and even after I received my items. I will buy from them again in the future if the need arises. They are very knowledgeable and not pushy at all. I was upgrading from SVS PB-16 Ultras, so I wanted to notice a difference and went with SI HS-24s and SpeakerPower Amps. I built 2 custom enclosures and used a GSG BTS Flat Pack for the 3rd enclosure. The Flat Pack was a great way to go. Thanks!!!

What can I say that hasn’t already probably been said.

I ordered 4x BTS 15” flat packs, along with 4x stereo Integrity SQL 15” woofers, plus a speakerpower amp to power it all.

Service was top notch. We had a slight hiccup with the last 2 woofers, but Kevin called and texted me personally several times to ensure I knew I was on his mind. In the end everything was delivered. Packaging and palletizing was exceptional.

It’s a great group over there and they’re wonderful to work with, including the folks at stereo integrity.

These particular speakers are excellent and you can see how nicely they play in my space from the EQ’d graph, reaching down to 10hz before I decided to put a HP filter on it. They may have gone down lower in the room but I had no desire to chase further.

Don’t think twice about the products or GSG team. They’ll treat you right.

Kevin and his team were instrumental to making my dream home audio system. I was not happy with any of the available big box speakers. I was drawn in by the devastators... But Kevin was able to steer me in the correct direction to the 18 inch MBMs.

He spent hours on the phone with me before my purchase, and during my build-out to help with small issues I had.

I don't know when this guy sleeps, because he WILL NOT end a call until everything is 110% understood

Amazing company and customer service. Talked to Kevin and he was extremely helpful with product information and even recommended an amplifier he does not carry because I was on a budget and that made the most sense for my setup. I'm not paid or compensated in any way for writing this review. I am just happy that there are companies out still out there with integrity and great customer service and GSG is definitely one of them!

GSG Audio Design is great. The flat packs are precision cut and go together much easier than I thought and the end result looks great and performs even better. You won't be disappointed. Kevin and Dan are very helpful if you need it and I really liked being able to buy a product designed AND made in the USA.

Great company to deal with! It is not Amazon so don't expect your order in two days, be patient, their team is working hard! couldn't be happier with the dual evolution 18's. a great alternative to the jtr cap 4000 at a lower price point

World class company to deal with. They will get you any combination of the best subs possible for any budget range. Easy to reach, great to communicate and work with, and very accommodating. You can tell that they are passionate about what they do, and they care about each and everybody they talk to. I couldn’t say enough good about GSG, Kevin, Jason who have always been great to advise, coordinate with, and just have chats with about subs and anything HT related.
