Our take on the Helix Blue B52C

by John Pollard
HELIX

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

German engineering meets car audio

Helix builds their low-profile Blue Series speakers to fit into more factory speaker locations while maintaining their high standards for sound quality. Helix earned its reputation by paying attention to the details, and these speakers really uphold the family name.

Helix Blue B52C

The Blue Series B52C 5-1/4" component speakers can handle up to 40 watts RMS of real-world power, so hook them up with an external amplifier if you really want to bring them to life. The added power gets you better bass and more accurate stereo separation, and your ears will thank you for the extra juice.

Woofer
Tweeter
Crossover

Woofer

Woofer: The B 52C component system includes woofers with injection-molded polypropylene cones and durable rubber surrounds. This process of cone molding assures a uniform cone thickness for superior linearity and clarity. It is also lighter weight and more rigid for decreased distortion and improved bass response.

Magnet cover: The woofers are shipped with a rubber magnet cover to protect the speaker. If the cover is removed the depth changes slightly:

  • Top Mount Depth: 1.931"
  • Bottom Mount Depth: 2.159"

Tweeter

Tweeter: The system uses 1" silk dome tweeters with neodymium motor structure. The tweeters can be flush mounted, surface mounted, or surface mounted at an angle using the included brackets. Once mounted, the tweeters swivel so you can direct them toward the listening positions.

Tweeter Dimensions:

  Frame Width Frame Length Cutout Diameter Mounting Height Mounting Depth
Flush Mount 2.160" 2.160" 1.835" 0.50" 1.0"
Surface Mount 1.845" 1.845" N/A 1.185" 0.4" (Screw Depth)
Angled Surface Mount 1.850" 1.835" N/A 1.355" 0.4" (Screw Depth)

Crossover

Crossover: Each crossover has screw terminal inputs and separate, attached 38" output leads for the woofer and tweeter. No crossover frequency or slope information was provided by the manufacturer.

Crossover Dimensions:

  • Length: 1.905" (plus wiring)
  • Height: 1.070"
  • Width: 1.385"

Nice mids and highs

Written By wolf, pittsburgh on Wednesday, August 07, 2013
Crutchfield Customer Review (What's this?)
 
Tried putting these in my subaru legacy in the front doors and dash speaker (tweeter) slots. Had to build harnesses for the tweeters, but the woofers went in the doors without issue. Despite the low peak RMS, these bad boys really sounded like garbage before I threw a clarion amp in the dash to power them. Mids and highs sound great, but bass lacks (as to be expected. from 5.25 speakers). The tweeters are loud, but they aren't harsh. I have my eq at -10 treble to compensate, which is a bit much. Mids sound great. Overall bass and treble aren't quite there. I need bass to "go to 11" and treble to "go to-11" for this to sound perfect. Not sure if I want to replace these, or try foam over the tweeter grill, and subs in the rear...
Pros:
Clear, warm mids. Tweeters are loud, but not abrasive
Cons:
Tweeters are too loud. Woofers don't have much bass, and it's easy to push them too hard, even with a 50 watt rms amp.

HELIX Blue B52C review

Written By Matt, Texas on Tuesday, September 25, 2012
Crutchfield Customer Review (What's this?)
 
I put these speaker in a Jeep because these are listed. They sound great. The fit great into a CJ7 and flush against the dash. Mid Bass levels add a kick to the front audio experience and the tweeters add the highs. Crystal clear sound from these and built well. Should be lasting enjoyment. One tweeter and one crossover didn't work. Crutchfield send me another set of speaker and I was good to go. I am very pleased with these and they add great sound....even for a jeep!
Pros:
Easy install, built well and clear highs and great mid levels.
Cons:
Tweeter and crossover was not working but they sent replacements.
