Product Details

Kicker DS40 DS Series 4" 2-Way Coaxial Speaker Pair

For an easy-to-install, drop-in factory speaker upgrade, the Kicker DS Series coaxial and 3-way speakers provide the clear midrange and crystal clear highs that ultimately define a great-sounding audio system—all while fitting neatly within your budget.

The DS40 4" coaxial speaker's woofer uses a heavy-duty motor structure and EVC™ (Extended Voice Coil) technology, not found in stock automotive speakers, to create remarkable performance with ultra-clean midbass punch, and the polypropylene cone with ribbed, UV-treated surround allows for precise, linear excursion and optimum sound in the critical midrange.

A coaxially mounted 1/2" balanced-dome, polyetherimide tweeter is driven by a rare-earth neodymium motor to supply outstanding definition, while a polyswitch resettable fuse protects it from being overdriven.

Specifications: • Power handling: 25 watts RMS/50 watts peak • Impedance: 4 ohms • Frequency response: 60-20,000 Hz • SPL: 88 dB • Overall diameter: 4" • Cutout: 3-3/4" • Mounting depth: 1-13/16".

Inside the box you'll find:
• Two DS40 4" coaxial speakers
• Two 12" lengths of tinned speaker wires with terminals pre-attached
• Four butt connectors
• Eight 1" self-tapping screws
• Eight speed clips
• Owners manual

For seamless sound throughout your audio system, the Kicker DS Series includes a wide range of 2-way coaxial speaker sizes to fit many popular door and dash locations: 3-1/2", 4", 4" x 6", 5-1/4", 6", 6-1/2", 6" x 8", and a 3-way triaxial 6" x 9"

Kicker DS40 DS Series 4" 2-Way Coaxial Speaker Pair
Kicker DS40 DS Series 4" 2-Way Coaxial Speaker Pair is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from suprise packageI bought this set of speakers a long while back when they were still new to the market, i had made a 6x9 baffle for the rear deck of a 94 sable of mine. Since the 6x9 set was hovering around the 70-80$ mark. I just needed some reinforcement to fill the rear end. I had a single 12" sub on a mono. And these filled in the midrange/highs crystal clear just running off a budget Kenwood excelon 395 HU with integrated controls for frequency cutoffs to the low end for the rear channel. Not perfect but matched well enough. And at 88db/sens, any head unit will push these quite well. These PEN 1/2" tweeters zing smoothly for such a low end model even after hours of DnB i never felt fatigued. A no brainer compared to similarly priced 4"-5 1/2" models if you need to just fill some dead air. You are certainly getting your money's worth. Also very sturdy stamped baskets, not once did i ever feel i was going to unnecessarily break or ruin the mounting tabs. Though the treated surrounds may still deteriorate and fatigue a bit after a few years, one that was always in the sun where i parked eventually flaked apart some on the surface but still worked, by that time anyone who has bought and used this set for a while will usually upgrade by then.

Are there any T/S parameters for these?

I am looking at doing a small boombox with these, just looking for the parameters to get the most bass out of them.
Asked by: MarcD
Unfortunately manufactures almost never post TS specs for small auto speakers like this. They will have an Fs around 70-80 Hz and a high Qts for free air applications. Based on this, a medium sized sealed box will give you the flattest bass response. I would recommend 0.3-0.4 cubic feet per speaker.
