Range Rover L322 (2003-2005) Harman/Kardon Logic 7 Subwoofer Speaker Driver Replacement Pyle PLPW6D

In this video, I give detailed instructions on how to replace the subwoofer drivers in the original Logic 7 Subwoofer that comes with the 2003-2005 L322 Range Rovers. The original driver units are 6" drivers with dual 4 ohm voice coils. The most economical unit available that fits the original design characteristics is the Pyle 6" dual voice coil subwoofer driver, model PLPW6D. I detail the installation process and also give some of my thoughts on the Logic 7 system and Harman's company ethos. I'm not affiliated with them in any way, but just a big fan...and I absolutely love the Logic 7 integration in the 2003-2005 Range Rovers, the sound is fantastic.
I'm also a DIY speaker builder and audiophile. I believe in good sound that can be scientifically measured as such and reject snake oil in the industry.

Wonderful.

This is very interesting, I am considering doing the same on mine but you miss out the most important key detail. How did it sound when it was reinstalled?

I buy recently this subwoofer and dont have any connections in L322, please picture where to connect him in the car? Tnx

I just noticed my drivers have no output to them . Previous owner has installed another brand. Connections seem fine Would not matching the ohms of factory speakers result in no output at all?

Great Great Video. I have a 2007 Range Rover SC. Do you have a recommendation for midrange door speakers that produce a little more of the low tones

Is this the same as the 06 with the logic 7 system?

Any possible way to fit 6.5” skar subwoofers?

Hi Gavin, the PLPW6D is pretty much an OEM-compatible replacement and has a cutout diameter of 142mm or 5.59." I did a google search for "Skar 6.5" subwoofer cutout dimensions" and saw a figure of 5.826" That's 0.22" more than the Pyle. Your first problem would be the diameter, you might need to grind out a larger diameter opening. And your second problem might be the mounting holes. Although the Skar looks to have 4 holes, I'm not sure if they would line up as closely as the Pyle. Regardless, I respect your choice on what driver to use, but the higher performing drivers really need beefier cabinets, porting, and even possibly bracing to make the most out of them. I don't think the little plastic factory enclosure would really let those Skar driver shine the way they deserve.

Voice coils that lost their impedance over the years ???!!! That's a first !! The speaker impedance is given by the length of the voice coil , to lose 0.1 of an ohm , you will have to shorten at least a few inches of wire from the voice coil :) !

Fascinating comment, let's explore this. From what I understand, you are right, and I am right too. Can't a blown voice coil (say for example in a driver with multiple voice coils) affect nominal impedance? Can't a damaged voice coil (say from rubbing during intense output or high excursion and the ensuing heat production) damage the coil itself causing a nominal impedance change? Why is it that the nominal impedance of a well worn driver never matches precisely that of a new driver (and I mean several ohms reading off reference).

@raduflorin6154 2 года назад

@@mjrgroup NO it cannot, the impedance is given by the length of the wire , if you have measured them and it gives you less on the multimeter, that's normal , as the multimeter picks up the DCR , not the impedance which is a bit lower then the impedance ( around 3.5 ohms instead of 4 ) !! By the way , did you had a chance to measure them , the original drivers are a bit weird , i have seen an L322 subwoofer, same shape , but the drivers had 3 mounting points ( in like a Mercedes 3 pointed star) , and the drivers had an orange label that said HAES ( made in Hungary) and they were DVC but 8/8 Ohms , not 4 !

Good vid...just 20min too long bro

I dont believe this is the Logic7 subwoofer, the Logic7 HK subwoofer is an obscure shaped driver (single subwoofer) and silver in colour

Thanks for your note. The initial 2003-2005 Rovers had the dual 6" drivers as part of the logic system, but in later years (2006+, and in some reported cases {late year production 2005}), the full size Rover switched to the proprietary shape single oval-shaped subwoofer you describe. From the workshop manual, the dual 6" subwoofer is visualized in the Logic 7 diagram, for the 2003-2005: workshop-manuals.com/landrover/l322-a/entertainment_and_information_systems/logic_7_speaker_control_diagram/
