Overview

Our take on the Audiofrog GS40

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.

Highlights:

  • 4" polypropylene speakers (pair)
  • for use with GS10 tweeter and GS410C crossover or in systems with active crossovers
  • power handling: 15-75 watts RMS (200 watts peak power)
  • frequency response: 90-12,000 Hz
  • impedance: 4 ohms
  • sensitivity: 88 dB
  • removable grille mesh and trim ring can be painted
  • flush-mount depth: 1-15/16"
  • warranty: 1 year
  • Our 60-day money-back guarantee

What's in the Box:

  • 2 Midrange drivers
  • 2 Grilles
  • 2 Grille mounting rings
  • Eight 1-1/8" Self-tapping screws (3mm Allen head)
  • 3mm Allen head bit
  • Instruction manual

Was scared to buy because im used to all the big names, and was worry they wount sound good. I was happy to hear they are great and sound great.

Awesome Sound, Build, & Price

Crutchfield Customer Review (What's this?)

Works and sounds great in my car. I was quite unsure how it would install in the stock BMW setup, but I managed to make a secure fitment and connection. These speakers are a steal at prices, BMW wanted to charge me $250+ for one component speaker, yet these fit the bill and sound better. The build quality of these was my greatest surprise, opening the box and seeing a solidly constructed speaker compared to BMW plastic speaker wowed me the most. The sound is hard to describe so all I can say is it sounds better than BMW stock speaker.

Pros: -Price -Build

Cons: N/A

Crutchfield Customer Review (What's this?)

Only giving 4 stars because the measurments of the trim ring are incorrect in the book. Speaker cut out I found to be 3 3/4 was a snug fit also the outside diameter was well over 4 inches of the grill and base I think it was 5 23/32 I have it written on my mdf sheet ill update later. Speaker wise holy cow im hearing details in my music I've never noticed. Hopefully with some more tuning time hopefully My full Audiofrog gs 3 way front stage will win some trophies for the price I don't think you'll find a better 4 inch mid!!to

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. We've listed the recommended range in the specs table.
