I've searched everywhere on s2ki regarding people's opinions on new components. I've read all the threads, but wanted to ask you guys a question

Currently I'm running Alpine SPS-600C coaxial speakers. They have good bass, but I'm looking for something stronger

I've narrowed down my choices to:
Alpine SPR-17S
Alpine SPX-17REF
Polk MM6501

It's going to be powered by an Alpine MRV-F340 amp:
55 watts RMS x 4 at 4 ohms
65 watts RMS x 4 at 2 ohms
130 watts RMS x 2 in bridged mode
2-, 3-, or 4-channel output

Going to be running components only, not planning on using a sub

is that amp going to be sufficient? Should I bridge it? Why do the Type R's have more wattage than the Type X's?

 

would like to know some suggestions as welll
im using sps-600c comps too
I also have an 8" jl audio. both powered by alpine mrp-f300

 

I'm most likely going to go with the Polk MM6501's

 

I had Polk dB series components and they sucked. The crossovers were garbage and the soldered conenctions broke. I have Alpine Type Rs and love them. Much higher quality in all aspects.

 

Based on numbers alone, the Polks go lower into the frequency response range and have higher sensitivity than the Alpines. But that's just on paper--I haven't compared them.

 

Unscrew the shell for the crossovers, or look up pics online and compare. Alpine is much more robust.

 

The sound of the Polk dB components alone made me stay away from them (I thought they sounded like complete junk). Sad to hear that their QC might be as bad as the sound output.

In the "lower end" I prefer Alpine Type-Rs and Infinity Kappas.

 

I have db6501's.
They suit my needs, and have almost convinced me to not put a sub in. Almost.

Most of the music I listen to does not have low bass, or bass that needs a 10"+ to give you good reproduction.

The tweets are a bit bright for my tastes, but I can fix that with a resistor (I think). Will have to go look that up when it becomes time.


I am sure the coating of sound deadening in the doors helps with the "bass" response of these speakers.

 

I believe that is the same model I had. If you mounted the crossovers in the door, I would recommend remounting them somewhere else to avoid problems.

 

I'm talking about the MM6501's which are different from the DB6501s

I've heard the DB6501s in person and don't like them
