Hi I have just bought a pair of pioneer 4inch splits. They are the TS-c1002 model(.http://www.pioneeraus.com.au/car_entertainment/speakers/tsc1002/index.html) I bought these because they are the only 4inch speaker ive found that claism to hold 50 watts rms power. I got home and read on the box though that at full range thay only have a 10watt rms power rating and that the woofer miderange cutoff frequency 450 htz with a -6db/oct HPF to get the 50 watts of power. Does this mean it has its own HPF built in to the midrange or i have to go buy a seperate one. It has an inline HPF filter but it looks like its for the tweeter and not the woofer. Also on installation i thought you would of ran your power rfom your amp to the woofer then to the tweeter but it looks like you run both straight from the amp. Wouldnt that give the tweeter to much power and do i also have to connect both midrange and tweeter to the same channel?
Sorry about this post being very long also. I have a HPF on my amp but its an at 80htz and im thinking thats nto going to be enough
thanx for the help and sorry if this is a stupid question

do i understand that you dont have a crosover with these?
never mind i read and found out. there is an inline crossover. this should handle the spliting of the sound between the midrange and tweeter... i honestly wouldnt put 50watts rms of power to these speakers though...
there are some 4" component speakers that can take 40-75watts rms of power but they are usualy very expensive... 4 inch speakers just dont have that much movment it doesnt take much to get them loud.

and a few others all make higher power hadnling 4" speakers.

If I read the specs correctly, the amp's HPF should be set to 450 Hz or higher for a 150 watt max signal input. That's a bunch of hogwash.
Yes, the specs say the woofer will do 70 Hz, but probably only at low power before the cone begins to break up. The tweeter is fine as it already has a passive crossover.
The best I can suggest is to listen very closely to these speakers as you adjust the amp HPF. Start at 100 Hz., and work your way up in HPF numbers until you get the desired SPL and clarity at moderate power.
This 4" speaker seems more designed for upper midrange and highs from the tweeter. Any low bass (under 100 Hz) will probably make the 4" driver loose control and spit out a large amount of distortion.

Yes the only problem i Have is that My amps HPF Is nto adjustable its either HPF at 80htz or its LPF at 80htz . It has this on the box aswell which im unsre about, its 50 watt nominal Woofer Cut off Frequency > 450 z with 6 db/oct HPF which im guessing you have already read. But It says when not using the network(what network ? the one i have to purchase seperatly?) connect non-polar capacitor in series (rated voltage of 63v or more and electrostatic capacity of 90 U(weird u symbol) F or below. Does this mean i have to make up my own passive crossover for them if i dont use the network........and have u heard of things already built into speakers to block off frequncy's because mabye one is already supplied? Any thoughts. Im not looking for this speaker to play any low to slightly mid frequncies whatsoever. Those brands I think i would have a hard time finding because i live in west oz. And also since I have no connectoins to be able to connect my tweeter to my midrange im guessing ill have to connect my tweeter straight to my amp......wouldnt hat be way to much power for my tweeter(Puttting both tweeter connections and midrange conntions on the same channel)? Cheers For your replys

Well, we discussed this at length in the chat room the other night. We agreed that 200 Hz., would be a good place to roll off lows to the 4" midrange driver. The tweeter already has a filtering cap on it.
A 200uF filtering cap with 30-50 volts operational range is fine. That's a good match for your midrange speakers. (Roll off begins at ~200 Hz.,
-6dB/octave, filtering slope)
Say you have 50 watts going to the splits:
200 Hz., full 50 watts
150 Hz., -3dB down (25 watts)
100 Hz, -6dB down (12.5 watts)
50 Hz., -12dB down (3 watts)
What to look for:
