hi guys first timer here be gentle //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

anyway i have been reading alot in the forums for awhile and just decided to join in and im now looking for some new comp for my car (scion tc) and have narrowed my list to the following

alpine type x refs

Pioneer TS-C720PRS

ppi 356cs

also i am currently using type r comps and type r coax int the back with an alpine 4 channel amp so this time i want something a little more "laid back" type of comps any suggestions would be greatly appreciated thanks guys!!!

 
How much power does your Alpine amp push? I assume you're going to be using the included passive crossovers with whatever components you buy?

What kind of music do you listen to mostly? What are you looking for really out of your comps? High-end cymbal sizzle? Hammering midbass? Clear midrange for detail on instrumental tracks? I know most people want a nice, balanced overall clarity, but if we know a little about your listening prefs, we might be more able to recommend something.

Also, I assume these will be going in stock door locations? Are you doors deadened at all? If not, might you consider doing some deadening and sealing of your doors to get the best possible sound?

Do you have a sub as well, or are you looking for your comps to play all the way down into the low, low range? If not, where do you plan to cross them over, removing bass frequencies? 80 to 100Hz is a pretty common place for most people, although it depends on if you're using the crossover on your amp (likely 12dB/oct) or if you may have a steeper crossover on your headunit (many offer 24dB/oct slopes).

I know... alot of questions. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

 
I got some re comps great components and you don't really want to run components in the back just in the front. Midbass in the back and then comps up front. I will sell you my re's for $120 shipped.

 
@trdoc i have the alpine mrv f450 running the set is this enuf? and listen to mostly hiphop and rnb from what i have read the type r are a little too harsh on the tweeters and i think i can vouch for that so looking for more clarity, and yes my doors are already deadend:)

@morgans thanks for the offer but im pretty much dead set on the list...

 
Ok, as for people telling you that you shouldn't run components in the back, it's just simply bunk and internet bandwagon-jumping. Here's why:

People talk about not using rear fill at all. This is true in competition circles, rear-fill is frowned upon, because it detracts from the front image and staging if not implemented extremely carefully.

However, in today's world of video setups and 5.1 theater in the car, as well as most people who couldn't give 2 shits about SQ competition, all they want is something to 'fill up' their car with music. Hell, most people don't even care about stereo separation, much less imaging and staging! Also people say that you should spend the majority of your money on components up front (since this is where the driver sits, and there will always be a driver in the car, but not always rear passengers). Saving money on rear-fill by using coaxials (or not having rear-fill at all) is one way to allow for a bigger budget for better speakers in the front. Arguing against components in the rear is mainly just an argument for monetary savings and installation issues, not sound issues.

However, this poster already has Type R comps, but I would guess those are in the front, and the Type R coax are in the back, making it a moot point. But if people want to have rear speakers, that's their preference and if they're not competing or trying hard to attain imaging and staging, then rear fill is no issue whatsoever.

Personally, I don't use rear fill, and haven't since removing the stock system. In my wife's stock Taurus, I keep the sound faded about 75% to the front, because my 2-y/o son rides in the back and I don't want it blaring in his ears, although I generally don't turn it up much at all when he's in the car. But I can see the point that for most people, it makes little to no difference, and in fact, most novice or new amateur enthusiasts will pick a rear-fill system as their preference over a front-stage only system. This has been my experience in the past. Do I miss rear-fill? Not a bit.

Now...

That Alpine amp is 70x4 @ 4 ohms, which isn't bad at all for most entry-level components. The one's you've listed will probably do fairly well with that amount of power, but if you've got the opportunity to bi-amp them, I think you'll be pretty pleased with the improvement. And you could run the rear-fill off your deck, instead of the amp (assuming this isn't what you were already planning). In a car that small, you can easily fill it up with a great set of bi-amped components, and those rear coaxes can fade out of the picture. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif I can't comment specifically on those sets, although the mids on the Pioneers have had their praises sung many times on the forums. The tweets are nothing special, and some people say they kinda crap out at moderate-to-high volume levels.

Other than that, I can't help ya. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Good luck!

 
trd i dont mind taking of the coaxials in the rear like u said if its gonna help or run it of the hu but what is bi-ampng? how do i do that? is that any diff with goin active?

plus given my current system what u think is the best?

OK, here's a picture of a standard crossover:

http://www.woofersetc.com/index.cfm?fuseaction=product.display&Product_ID=1237

Notice there are 6 terminals on each crossover... 1 pair of inputs and 2 pairs of outputs... so one amp channel goes in, and gets split to go to the tweeter and the midrange. Make sense?

Now, here are some bi-ampable crossovers:

http://www.woofersetc.com/index.cfm?fuseaction=product.display&Product_ID=4985

http://cgi.ebay.com/MB-QUART-CROSSOVERS_W0QQitemZ230180868721QQihZ013QQcategoryZ18800QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

What stands out about these? They have 8 terminals, which in a bi-ampable crossover means you have an input for mids and an input for highs, as well as an output for mids and an output for highs. So you can run a separate amp channel to each speaker, and still use the passive crossovers. So in your case....

You could use a standard crossover setup and run a single channel input from your amp to each side, then run your rear coaxes off the other amp channel. So you'd in essence be running 70x2 to the front components, and 70x2 to your coaxes in the rear.

With a bi-amped setup, you could run 70x4 to your front components, and your coaxes off the deck. This is what I would recommend. I personally prefer sending plenty of good clean power to the front components. I have noticed a significant difference every time when going from standard passive to bi-amped, or actively crossed over with a separate amp channel for each speaker.

That would be my recommendation.

So, as to your choice, I'd look into whether all of those sets offer bi-ampable crossovers (obviously the Pioneers do), if one doesn't, if it were me, I'd exclude it.

 
You can bridge the amp and deliver it as one channel to a regular crossover or a bi-ampable one. I've tried that, too, and unless your amp makes ALOT more power bridged, it hasn't seemed to offer alot of benefit to me.

Yours does 70x4 or 200x2... so you would be bi-amping at 70x4 (140 watts per side), or mono-amping at 200 watts per side. It might offer some benefit, but I don't think the Pioneers will benefit from the extra power. Can't say about the other sets.

 
ok kinda figured bi-amping do u guys think this the best way for the comps i mentioned with my current amp or do i need a new amp as well? all the sets i mentioned are within the 65-75 watt range.
