HERTZ CPK 690 PRO LINE
(6 X 9) MM (IN.) | SYSTEM | 360 W | 4 OHM
THE AUTHENTIC HERTZ SOUND EXPERIENCE FOR THE YOUNG ENTHUSIASTS
The latest addition to the Cento PRO line is the CPK 690 system equipped with an elliptical woofer to avail of the 6 x 9 door placements, which are particularly common in the North American market, such as for the models of Toyota and FORD groups.
Like the other speakers of the Cento PRO line, the woofer cone is made of pressed paper, the most suitable material to obtain a linear and controlled emission even when the woofer is driven with very high power.
All electroacoustic parameters have been optimized to obtain maximum performance with door installations; we therefore find a magnetic group and voice coil improved for an excellent power handling and a lower resonance frequency.
The large emission area of the CP 690 increases the woofer efficiency and extends the response down to 35 Hz.
The crossover made with selected components, features a low-pass filter on the woofer with a 6 dB/oct. slope and
12 dB/oct. on the tweeter with three levels of attenuation.
CPK 690 is dedicated to the young enthusiast who wants a front row seat at their favourite concert while sitting comfortably behind the steering wheel.
CP 25
- Soft Tetolon® fiber 29 mm (1.14 in.) dome and 25 mm (1 in.) voice coil cooled with ferrofluid, for a natural and yet detailed reproduction of musical nuances.

- Neodymium magnet with high-density magnetic flux, optimized for maximum control during high-energy dynamic transients in the mid-high frequency range.

CP 690
- Pressed-paper cone with FEM-optimized geometry, it combines rigidity and lightness for a color-free sound.
- 30 mm (1.2 in.) double layer voice coil sized to maximize fhigh excursion and power handling.
- High-density flux ferrite magnet combined with low-carbon polar plates for reduced distortion at high power levels.
- Compact and transparent three-spoke basket, acoustically combin

Still the champ.
Color: Black/Negative Digital/Gray, Color: Black/Negative Digital/Gray
I absolutely LOVE my Casio GBA800 that I have bully bars on, so she's quite huge. Analog with Bluetooth, pretty cool. If I ever remember to use such things. I have a phone and laptop on me usually, why do I need to play with my watch? I want to tell time, that's it.
Comes along a good sale for an Ironman, and I used to be a complete fanatic for only Ironman for a real person's needs. Why not, I've been fighting the Casio all day with my coat cuff, let's get something a bit slimmer for when it's coat season. See if they're still great. Yup! Sure is.
It's been probably 25 years ago last time I wore this style of Timex, and can you believe the button setup and beeps are all still the same as way back when! And somehow, my subconscious remembers the button presses. Wild.
This thing is light as a feather, and I got the inverse LCD for fun, which is cool as all get out, but takes some getting used to. The Indiglo sure looks awesome, though, and she's like Knight Rider down there. Stealth. The display is big, and easy even for my old eyes, the band is supremely comfortable, and there's a strap catch that actually works correctly! With no Bluetooth, battery life should be outstanding - always used to be. Back when watch batteries were like $12 each. There goes my allowance! Lol.
I'm very impressed by this timepiece. I really didn't mean to order order it, but, oh well. I love it as much as my Casio. Affordable tough watches rock!

This Timex Ironman lives up to its name
Color: Black/Digital Gray/Black
Timex Ironman watches have been with me for a decade. This particular one I just ordered as a backup for the same one that I have had for seven years (and still works perfectly). I don't know why I ordered a backup except that I love it so much that I couldn't fathom the idea that Timex might discontinue this model. Why do I love it so much? Because it is functional in many ways. Aside from its durability, reliability and the fact that it fits on my wrist so comfortably, it is easy to read and extremely useful for tasks that need countdown alarms as well as regular timers (it has three which you can set). Since I gave up "fashionable" watches years ago in favor of practical, easy to read, multifunctional devises I found this Timex the best of all the other brands that I have tried in this category. Years ago, President Bill Clinton, who jogged regularly, was heavily chastised for wearing a very functional Timex Ironman watch in the Oval Office instead of what the professional politicians considered appropriate for a President. It was then that I realized how important it was for a person to wear a watch that they loved, and that was functional for them. At that point in time I had many other watches that I didn't jettison until later when I realized that I need only wear the watch that I loved and was useful to me. I still have another watch that I saved for "appropriate" times out but have only worn it once. The rest of the time my Timex Ironman stays on my wrist wherever I go.

A very comfy, pleasant casual sports watch- especially good for training
Color: Black/Digital Gray/Silver-Tone, Color: Black/Digital Gray/Silver-Tone
The Ironman series of watches has been around for about 40 years now, and with good reason. The current iteration doesn't disappoint. It's light weight, easy-to-read, has a good backlight, offers simple operation, great buttons, a decently loud chime, and is a feature rich watch. I purchased this one on a lark; it was sold as "used- very good" from an Amazon warehouse for $20. The Timex packaging/ box was damaged, but the watch itself was new, wrapped and seemed unused. Since I do not wear an item's packaging, I always look for such items when shopping on Amazon, as it can save quite a bit. In this case it was $12 less expensive, or about 1/3 less costly.
I have owned a digital watch for over 40 years; from left to right in the photo- my 1980 Seiko (owned since new), my daily Casio, which has solar and atomic clock radio signal time setting, and the Ironman for you to compare size. Owning a number of Casio digital watches, I was pleasantly surprised by the comfort and ease of use of this Timex Ironman. The Ironman does feel somewhat more "plasticky" that some Casio watches I have, which may influence some buyers. But once you get past that feel, if you like the look of the watch, it's a great offering, especially at a $20 price point. The on the Ironman, a chronograph, a countdown timer, a second time zone, three alarms, 30 lap records, occasion reminders , and a perpetual calendar make it comparable, or better than many of the similarly priced Casio offerings. The Ironman does not feel quite as substantial as some of the lower cost G-Shock offerings I have tried, but is at least as comfy on my 7 1/2 inch wrist. Water resistance seems fine at 100 meters, and the recessed plastic crystal should avoid most scratches. The features should be very useful for those who do not want to wear a smartwatch for training. I hope this review has been helpful.

this is the perfect daily everyday use digital watch........
Color: Black
hands down the best edc digital watch available, this watch is everything you need at a quarter of the cost of other digital watches. we all know the durability of iron man watches its legendary, but where this watch beats even other iron man offerings is the size of the digital numbers displayed a bit larger for aging eyes and what makes it even more durable than the other iron man watch's is that the instructional labeling of the buttons is under the glass and wont fade or rub off under use making it look cleaner and newer for longer. now lets mention the size or foot print of this watch, i own several watches from competing brands and almost once a day i hit the watch on something a door knob a table corner, but when I'm wearing this Timex 40mm i never hit it on anything due to the thinness of the watch.
