About the Audiofrog GS40

Build an Audiofrog system

The Audiofrog price tag sets its speakers apart from the run-of-the-mill but buys you astounding car audio. When they demo'd the GS Series at Crutchfield headquarters, I listened, slackjawed, fantasizing about a world where speakers this powerful and clear were installed in my car. I'd pair them with Audiofrog's GS10 tweeters and the optimized GS410C crossover system, but there's always the option of using active crossovers in a three-way system with GS60 6-1/2" midrange drivers. The beauty of Audiofrog's a la carte approach is that it imposes no limits on your ultimate car audio vision.

Audiofrog GS40 4" Midrange Speaker

This little 4" wonder is ready to change your daily drive.

What a woofer

Audiofrog designed the GS40 4" woofer to deliver the midrange details in a custom component system. A responsive polypropylene cone provides high internal damping for smoother frequency response, and Audiofrog uses a 1" copper voice coil to enhance power handling.

Creative installation

Audiofrog was founded by experienced installers, who know all the pitfalls and shortcuts of custom installations. With the included mounting hardware, you'll find custom fabrication of a speaker location much easier. The GS40's removable ring can be painted or upholstered, depending on your vision for your interior. The grilles are ideal for painting as well.

Product Research

Features

Durability: The Nitrile-Butadiene Rubber (NBR) surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.

Multi Component Systems: The GS40s are designed to mate with the GS10 tweeters (item number 898GS10, sold separately) using the GS410C passive crossovers (item number 898GS410C, sold separately). They can also be used in an active system with (or without) the GS60 woofers (item number 898GS60, sold separately) and the GS10 tweeters using an electronic crossover.

Note: Audiofrog recommends a low pass crossover set no higher than 3.5 kHz. The minimum recommended slope is 12 dB/octave.

Power Handling: Audiofrog lists two RMS power figures in the manual; 70 watts RMS in the technical specifications section and 15-75 watts RMS in the recommendations section.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
for my 2014 BMW i3 [ New User  Jan 29, 2018 ]
A
Good reviews on you tube also made in the USA and I was looking for a 4" mid to add to my system to create a 3 way system up front for better staging and sound separation. [ luis  Dec 14, 2017 ]

Size and quality. [ Reed  Aug 22, 2017 ]

Q
What is the diameter of the speaker, excluding the speaker grill ?
[ frank  Nov 23, 2019 ]
1 answer
A
4-11/32 is the overall speaker diameter. 3-11/16 is the inside diameter of the mounting plate - you'd want about 3-7/8" hole to mount. 4" should work too.
[ Alex  Nov 30, 2019 ]
