Alpine Type-R or Infinity Reference Components?


Junior Member
Ok, I’ve been doing a lot of research, but yet I still can’t make up my mine. Perhaps you experts and sound gurus can give me some pointers.

I’m planning on powering the components with my Kenwood head unit. Below are the specs:

Kenwood KDC-MP922:

• high-pass crossovers for front and rear outs (12 dB/octave, selectable 40/60/80/100/120/150/180/220 Hz)

• low-pass crossover (12 dB/octave, selectable 50/80/120 Hz)

• 22 watts RMS/50 peak x 4 channels

• CD frequency response 10-20,000 Hz

• CD signal-to-noise ratio 105 dB

• FM sensitivity 9.3 dBf

The Candidates!

Alpine Type-R Specs:

• Crossover Attenuation Level : 0db, -3dB, -6dB

• Crossover Size (in) : 2-9/16" x 4-3/4" x 1-3/8" (WxHxD)

• Crossover Size (mm) : 65mm x 120mm x 35mm (WxHxD)

• Frequency Response : 40Hz - 30kHz

• Impedance (Nominal) : 4 ohm

Sensitivity : 86 dB/W/m

• Tweeter Mounting Depth with Flush Kit (in) : 5/8"

• Tweeter Mounting Depth with Flush Kit (mm) : 15.4mm

• Tweeter Mounting Diameter with Flush Kit (in) : 2-1/4"

• Tweeter Mounting Diameter with Flush Kit (mm) : 56mm

• Woofer Mounting Depth (in) : 2-3/4"

• Woofer Mounting Depth (mm) : 70mm

• Woofer Mounting Diameter (in) : 5-3/4"

• Woofer Mounting Diameter (mm) : 145mm

• Power Handling Capacity (Peak) : 200W

• Power Handling Capacity (RMS) : 50W

Infinity Reference 6000CS Specs:

Power Handling, RMS: 90 Watts

Power Handling, Peak: 270 Watts

Sensitivity: 92dB

Frequency Response (±3dB): 53Hz - 21kHz

Mounting Depth: 2-1/16" Mid/Woofer, 1/1/4" Tweeter

Impedance: 4 Ohms

The Questions!

I listen to all kinds of music, rock, rap, pop, classic, dance, and etc, so I’m looking for the best overall/complete system our of the 2 above. And I DON’T have a sub!

(1)Which components will sound the best (a best match) for my Kenwood head unit?

(2)If I was to get an amplifier for the components, which (2 Channel) Amp would be the best bang for the buck ($100-$120)

(3) Are there better sounding components out there in the $150-$200 range that would match the Kenwood head unit?

That’s all, thanks in advance.


I have the infinitys and they're really good for the price. I amped them with a jbl P180.2 and I don't get distortion whatsoever. With any components I would recommend that you amp them. If you want bass, you're going to need subs because the infinitys won't give you enough.

As for the Alpines, I haven't heard them yet.

I have the Infinity's and power them with a RF 400a4 - and I love them. I was torn between the same two speakers you are looking at, but was able to find the 6000 CS's for about $120 shipped (new), and I couldn't pass it up. I think I made the right decision, for what it is worth! //

I used to have the old infinity kappy 65cs ( i think that's what they were) the green ones, and I heard the type-r's the other day and fell in love with them. I think they might have a little more bass but they both sound great. You should try to listen to both and make your decision based on what you like. Remember to ask what they have pushing the two speakers too so you aren't dissapointed if you don't put enough juice to 'em. :thumbsupw

Off a head unit, the infinity's will do better. They have a better efficiency. The Type R's need to be amped....the infinity's should also, but i understand what your doing.
