Does anyone have the FULL specs for every speaker driver in the H&K config? In fact, to be useful to all, for both sound systems?

Sepcifically, diameter, depth, location, Ohm value <--- what I really seek.

Thanks!

Don't forget the Thiele-Small parameters and sensitivity.

 

These are not published so they are going to be hard to get.

as for the diameter, depth location and ohm value i believe all of those are in a thread here somewhere. Search with google and you can probably find it easier that with the in site search

 

mainly I am interested in sensitivity. I did a swap on a G35 coupe some time back, same sort of deal, "premium" blose sound system, swapped speakers for a near match in impedance and light year difference in sound without burning out the amp.

 

I haven't measured the new h/k drivers, but the HiFi door woofer is around 86dB. The midrange is around 87-88. I say "around" because these are low quality speakers and they vary quite a bit from driver to driver. I've measured the rest of the T/S params, but they aren't going to be of any use to anyone.

Based on my experience with other BMW systems I am sure the new h/k is very similar.

As for mounting diameter, depth, etc, it depends. For the door woofer, the mounting depth is 2.93" max and the cutout is 5.5". The mounting height can be limiting, depends on the OD.

The midrange is more complicated - it isn't a simple cavity. The overall flange limit is about 5.05". The depth limit is 2.125", but it depends on the magnet/basket shape and diameter.

regarding the regular (not H/K) Gen 1 lower front door speakers in case anyone in interested:

"I don't have all the data compiled into a concise report yet, but I can share info on the stock drivers off the top of my head.

DCR/Re: 3.5 ohms
SPL 1w/1m: 89.2 dB
SPL 2 VRMS: 89.7 dB
Qt: 0.7
Fs (resonance frequency): 75 Hz
xmax: 2.5 mm
Frequency response: OK: hole at 1kHz, rough response above 4kHz, with spike at 5kHz. Response extends to 10 kHz to meet passively crossed over tweeter (1st order, capacitor).
3/4&" Voice-coil, good for 20-30 watts continuous"

"The "specs" for the stock 5.25" speaker are: 89.7 dB sensitivity, 75 Hz resonance, 75 Hz-10 kHz +/-3 dB, 3.5 ohm, 3 mm xmax, Qt=0.68. The crossover point with the stock tweeter is about 9kHz (be careful about going lower, image could be less stable). The tweeter has nice response from 3kHz-20kHz, and is as good as most aftermarket &quot;balanced dome&quot; tweeters. I'd leave it in the system unless you buy a 2-way kit, or really want an expensive 1" dome."

 

Cristo mentioned this - but keep in mind that is a 1st gen non-h/k door woofer. The layout of the 1st gen is totally different, yielding completely different speakers, and the non-h/k speakers are also different animals. They get even less power, and a trade-off was made between bandwidth and efficiency. I'm surprised to see anyone say they measured that driver at 75Hz-10kHz +/-3dB. I'd be interested to see the test conditions, equipment, and processing applied.

To give you a sense of how much these speakers vary (an indication of poor quality and poor manufacturing processes), these are our measurements of the same speaker from a different '03:

D 112.8 [mm]
Re 3.37 [Ohms]
Fs 74.69 [Hz]
Zm 22.41 [Ohms]
BL 4.01 [N/A]
Qms 3.819
Qes 0.676
Qts 0.574
Vas 9.252 [liters]
L10k 0.28 [mH]
n0 0.54 [%]
dBSPL 89.46 [1W/1m]
Ms 6.88 [grams]
Cms 0.66 [mm/N]

Note the difference in Qts (TacoTim measured ~0.7). That is big difference for what should be the same speaker - and the two drivers would sound significantly different.

The bottom line, to bring it back to the OP, is that speakers in the 2nd gen are comparably low-quality, but even lower efficiency.

 

Well, since I'm already in the files I guess I might as well post the 2nd gen #'s (I didn't want to get distracted with this, but too late )

Think this might be helpful. Found it on the Harman/Kardon webpage.

Kevin great info - hopefully someone can find similar on H&K stuff.

 

Unlikely - I didn't find those, I measured them in our lab. Harman certainly isn't going to publish it - at least not honest numbers. I will be pulling them next time I've got a MINI with the new h/k in the shop, but the numbers are virtually useless in this situation. Maybe tell me what it is you are hoping to gain from them and I can try to be a bit more helpful.
