    I made one comment, on one post you made. If I was trolling you, your mom would text you.

    There's a big difference between using a incandescent bulb as a "protection circuit" and using it as part of a RC network. I don't have the wiring diagram that Luke used, but I suspect that's what he did. I've said that from the start - this is what I think happened. It's my educated guess.

    Now, I'll be glad to debate with you where GAS when wrong in their "business". Let me know where you want to start. I know you're one of Luke's friends - so I get it. But for the love of God man, let it go. It's over. Move on. Luke isn't coming back.
    Seems like you are the one who can't let it go...

    George, your lack of actual knowledge on this topic is showing.

    Crossover Fuses at Parts Express. Choose speaker crossover tweeter protector lamps, bulb replacement tweeter protection lamp for crossovers plus.

    Well, if you browse through that bimmerforums e38 PNC link where he blow us, and takes his marbles home, there a lot of talk about 2 different batches of the PNC's that he did. One worked good. The second batch was unlistenable it was so bad. IRRC even the infamous Jordan chimes in at some point - having bought two, one good, and one bad. Being that all those caps and inductors are run-of-the-mill, off the shelf stuff from partexpress.com, it's kinda points to the bulbs.

    He're what I think happened. Luke took a multimeter to the bulb and measured it's resistance.....and said "Hey, I can use this as a resistor in my crossovers!" - But what he didn't know was that as a bulb filament heats up, it's resistance changes dramatically. Basically a bulb is a very poor resistor. (Resistors, at least decent ones, should stay the same value of resistance throughout their wattage range)
    Dome light bulbs were definitely used in crossovers designed in the say 1970s and 1980s, mostly as tweeter protection as you started to dump more power into your speakers. Wired in series, it would act to prevent damage to the tweeter. I don't think Luke measured the cold resistance and had a lightbulb go off over his head :nice:, I think he was paying homage to the crossover networks / tweeter protection concepts of yore.

    I hope these bulbs weren't placed in a filter circuit, since you want the filter frequency to be a set value, and I doubt they were.

    Yes - it's in all of his work, sadly.



    There's also along list of screen captures of him holding people boxes hostage if they dare to leave feedback for him.

    Ported vs Sealed box is a question for the ages. Generally speaking, ported makes a sub louder, but less tight sounding. That's good if you like low and loud. Or if you only have an 8" woofer, it's extra good to get down low and make it a bit more pronounced. When you have a 12" woofer, some people go for sealed to make it tighter, and more accurate, but less "I want to shake the neighborhood" - With that said, there are exception to every rule, and it depends on a lot of factors.

    I installed some of his products (ported through the center parcel shelf, ported through the seat and ported through the stock speaker locations), they all sounded great, even so with the cheap speaker he would throw in for free when the customer requested.

    Also installed one of his crossovers, didn't have any weird light bulb, was actually a well put together product, but this was many years ago - not sure about his 5 series products, or stock upgrades.

    EDIT: Looks like 2015 was the last time we saw anything from him at the shop...

    Tell that to dozens of e39 guys on Bimmerforums that received units that were so unlistenable, they would try thing like unplugging a tweeter just to make it sound decent (and no, that didn't work). Luke's response to that was to "go pound sand, I'm done"

    So yea. The crossovers were a flop for them. For sure. https://www.bimmerforums.com/forum/s...SP-E39s/page11

    Eventually he got a different batch of bulbs - or something. And "poof" there goes all the work that was done.

    I tried to relay this info to him by a friend of a friend to tell him this, but he didn't want anything to do with that advice.

    And should we talk about all the posts he deleted when he was a mod that criticized his work in any way?

    That was always my impression as things went down. I bought a compact box from him and received it in a timely fashion. When I was heavily into electrical modifications of amplifiers and head units, him and I also spoke on the phone about product ideas and such. He was super enthusiastic about audio and pushing limits. As far as what the "real" deal with GAS going under was, I have no idea since I did not get involved. It was sort of an unfortunate train wreck to observe on here.

    Is this magical luke box just a box that fits in an e30? Maybe there is a market for a Dave box.

    @Five5peed May I ask how you sent the money? Did you actually receive the item, or are you waiting on it???
