New to Forum E60 stereo suggestions

Hi all,

Just got an '09 535i x drive after my beloved 01 740i waved the white flag with 202k. Love the car but the non-logic 7 10 speaker setup with nav is pretty anemic. I have the bass covered with a JL sub box that i'll install but need some suggestions for the interior.

Have looked into Bav Soundwerks but would prefer to see if another relatively painless option exists from brand name speakers that would sound good running off the factory power and not be too awful to install.

Any idea where/how many/specs on the factory amps?

Thanks in advance and enjoy the ride

Armen

What's your definition of "relatively painless option"??? Less expensive? The BAV are closer to plug and play, the only other option on this forum (installed by Oceans10) is a little known German product specifically fitted for BMW, including E60 5 series.

He replaced tweeters, 4" mids in front doors, and the underseat woofers. They also come with cross overs, but not needed.

I've not seen any other options...

Sorry can't help, no L7 was a dealbreaker for me...passed on 2 very nice 550's that somehow didn't have L7.

The Logic 7 amplifier actually fills more boxes than just "amplifier" on the block diagram:



- 9-channel amplifier (center/Front L+R/Rear L+R/Side L+R/Underseat L+R)


- DSP sound processor with fixed equalization and crossover filtering (active crossovers are around 150 cycles - mid/tweeter handoffs are handled passively and mechanically)


- A BMW-approved implementation of Lexicon's Logic 7 ambient "surround" processing (if you read the white papers on Logic 7 technology, you see that it's really a recording technology. It was not invented as a way to play back stereo recordings.)


- MOST optical to analog DAC


I mention all these functions because it's important to know what the output of the Logic 7 amp is like. It's not a full-range signal, it's not a flat signal. Most install shops don't have the gear on hand to measure the electrical signal out of a stock system, and so most shops are at a disadvantage when working with this sort of upgrade, as it turns out.




There are two paths to choose between to upgrade the sound in cars with the Logic 7 system:


A) Take the processed, crossover-filtered analog outputs of the Logic 7 amplifier, and attenuate them and then re-amplify them with a new amplifier - possibly applying some sort of correction to the signal along the way.


B) Use a MOST-input device paired with an aftermarket DSP device, and replace the stock amplifier with aftermarket gear which acts as a MOST-to-analog converter, along with a user-adjustable DSP equalizer, crossover, and preamp. Then you can connect new downstream amplifiers.


Approach B sounds amazing. B also costs $1800 before you've touched an amp or a speaker. For that reason, 98% of all Logic 7 upgrades involve approach A - which we make sound great. We have used both.




One path we've taken with the E60 is to use the Zapco DSP amplifiers, and mount them under the rear deck or under a subfloor. These amplifiers have optional external attenuators which work well with the Logic 7 amp outputs, and the DSP allows us 10 parametric bands per channel, numerous crossover filter options, and time delay correction per channel. The ability to EQ L and R differently and the ability to use digital delay to offset the differing path lengths




Another approach that helps a lot is to use a woofer driver that has great midbass response. This helps anchor the drum kit in the front.


A system like that, with Zapco DC350 amplifiers - one for the underseat woofers, and another for the front speakers - Zapco attenuators and cables, Morel Hybrid Ovation 4 components, and Jehnert XE200 underseat woofers, would run about $3950 installed and tuned here at our shop. This includes plug-in harnesses, all wire and cable and hardware, and our BMW speaker mounting adapter plates and rings. We do systems with lower costs than that, and we do some with higher costs than that. Since you have Rear PDC, we would run your fader all the way to the front and the Rear PDC audible alert will still work through the stock rear speakers independent of fader position.


Another approach that we have used, that is somewhat common, is to use the JBL MS processor to improve the sound of the stock 4" and tweeters, and then upgrade the underseat woofers and add a small amp just for them (the MS processor has 30W per channel that can drive the stock mids and tweeters acceptably). This is a good approach for someone who likes the Logic 7 idea, but wants better tonality and better dynamics. It's not my personal favorite, and I'm not sold on the Logic 7 technology (although I must mention that the MS implementation is far better than the BMW implementation). That approach starts at $2400 installed, using an Arc Audio KS125.2 Mini amp and Jehnert XE200 underseat woofers. This also includes our adapter parts. Since you have PDC, we would not use the rear speakers, just the rear side speakers, and dedicate the rear speakers for the PDC alert.

Very knowledgeable ... however, what about putting a 12 inch sub along with its dedicated amp in the trunk?
