    Hi all

    Had my SLK door speakers upgraded over the weekend. The original OEM speaker was distorting on the r/h side.

    I'm a bit underwhelmed considering the price of speakers were £165 AND there is now a slight bass distortion on the l/h side now! :eek:

    I don't think it's the speaker itself, more to do with something inside the door vibrating.

    The technicians had my car for 4 hours what with having to install hands free head unit. (Taken out of previous car).

    Car is back in Weds to sort out the speaker! Grrrrrr! :mad:

    Kyle :(

    They are called Rockford Fosgate Punch Series. The right speaker sounds awesome! Lol

    They do look very good! Should be very nice in the SLK. I thought about putting a Pioneer underseat sub in mine but settled for the "grippy-Scotch" Alpine SPG 17Cs in the doors.

    They are fine, but a bit 'championship' compared to the Rockfords. ;)

    When I collected the car they suggested fitting a pioneer active sub behind the seat for a bit more ooomph! (must be a technical term).
    I'll wait until they put right the prob of left hand speaker first. :(

    Blimey! Is anything ever straight forward these days?

    My all singing all dancing £165 door speakers were not designed to cope with bass frequecies so Ive been told by the shop!
    Im not a bass freak but I do like a little bottom end to my music.
    The shop has suggested the speakers I bought bring out the mid and high frequencies. To add bass they suggest a subwoover at £200.
    I must have MUG tatooed on my forehead! Why didnt they advise me of this before the install of the door speakers?
    Im thinking this is a synical ploy to get more money out of me.

    Without being able to dial in any bass on these speakers they sound tinny and ****e!

    Grrrrr!

    Are they the correct impedance for the head unit, they only way to get more bass it to make the mounting more substantial, if the door frame is not strong enough,, then the speaker frame (chassis) will try and move counteracting the bottom end, and this is bass lost, most all round speakers have to cater for both ends of the sound, and with out a dedicated pressurized box for the speaker, then the power output is very limited, and the cone will just flap

    The head unit is 'high end' so I imagine the power output is not an issue.
    If the original r/h speaker hadnt been knackered Id have been happy with them. They put out a nice rich deep sound.
    Now Ive paid a lot of money for speakers I cant load any bass on. I dont get it?
    I shall be having words with Uplands Car Radio tomorrow.

    Speakers mounted low down in the doors should be more of a bass speaker rather than all round, mid to high frequencies only go in a straight line, so no point in having a complex speaker in the bottom of the doors as you will not hear any benefit, any mid range should be mounted higher up and tweeters at ear level. You could have bought a basic low frequency speaker with a stiffer cone and suspension for circa £15 to £20 max each

    Looks like I'm resigned to fitting a subwoover. Not because I want one, it's because I need one to acheive the sound I want from £165 door speakers. :(

    Just a quick update on this.
    Uplands Car Radio have fitted a Kenwood active sub behind passenger seat (not enough room to place under seat). They left the Rockford speakers in tbe doors and didnt replace with next model down as a 'good will' gesture.

    Im HAPPY with sound now, plenty of bottom end for all my drum n bass tracks! Lol
    :)
