Which one for my setup?
Which one for my setup? I am wanting to replace my sail panel speakers due to the fact that mine are blown and I would like a little more bass than stock. I have the Alpine CDA-9856 h/u and am not running an amp. Which one of these could I get the better sound out of?
Image Dynamics 6.5" Midbasses
sens. 91 dB
2 ohms
RMS power: 150 Watts
Frequency response: 65Hz-4KHz
OR
Audiobahn AMD60Q's
ses. 93 dB
3 ohms
Power Handling: 200 watts R.M.S. /pair
Frequency Response: 30Hz - 5kHz
2 Layer High-temp ASV Voice Coil
Since the Audiobahns have a little more resistance would that mean that they wouldn't be quite as loud as the Dynamics? This might be obvious but I'm not familiar with frequency response and RMS power yet.

i'd say the dynamics, the impedence is lower and your alpine is only pushing out like 20 rms anyway. the audiobahns have a better freq. range, 35hz lower, but they would have less power getting to them. i'd say you would get more potential with the dynamics
as far as frequency it is just the tone... er i think that is the right word, the speaker puts out, the lower the more bassier, higher gets the peaky stuff. rms is the average power it is getting, dont buy stuff for their max power output cause that is crap. that is just how much power they can handle before they blow, but they might only handle that for a split second. rms is max average power it can handle, so the higher rms the higher power you can run to them and still get clear sound out of them. your alpine is prolly rated at like 50w per channel, that is max power. that is why i say it prolly only puts out like 20-25.

If the speakers are driven directly off of an aftermarket H/U, why not put in full range speakers? Also, contrary to the above, the Audiobahns should be just as loud at the same volume level (according to the relative sensitivity specs for each, the AMD60Q's should be technically slightly louder. But not enough that anyone would be able to tell the difference) and they will tax your head unit less by drawing less current than the ID's. Of course, I can not vouch for the SQ from either as I've never heard either one.

The higher current of low impedance speakers gives the advantage of more magnetic force in deflecting the coil making it 'hit' harder. This is only advantageous in subwoofers. The trade-off is that subs are necessarily made stronger and stiffer to prevent them from shredding themselves, which means lower sensitivity, requiring higher power to overcome.
