Hello all, first time posting here. Interesting topics!
However, this all seems very one-sided to me. I know less about speaker design and measurement than probably most of you all, and certainly less then Amir (or Danny) – and I will not comment on this Ascend modification. But: Has anybody here actually listened to any of Danny`s mods (to avoid the term upgrade) or are you judging them just from measurements other people performed? I am far from being susceptible for snake oil or even a Danny fanboy, but at least I can talk about real-world experience.
I have a (now vintage) B&W 802 Matrix speaker that had developed a fault in the stock crossover. So I went and ordered a replacement crossover from US based specialist who builds crossovers with 100% stock design, but no PCB and better parts (no boutique stuff, though). Out of curiosity I repaired the stock crossover with new stock parts, so I could compare. The upgrade won, although the tonality remained largely unchanged, unsurprisingly. But it was still missing something. As I had already thrown unreasonable amounts of money at these old speakers, I decided to go all in and ordered Danny`s upgrade when it became available – although Danny himself said (in the video) that there was little room for improvement. So I ended up with three crossovers for the same speaker, I even built an A/B comparison test rig, just for fun. Bottom line: Danny´s crossover won hands down, also with wife, children and friends in a blind test (they did not even know what I had changed when switching). Dynamics, imaging and resolution were clearly improved. Way beyond just being confirmation bias.
I had kept the stock crossovers to be able to revert to them and preserve the resale value, but went ahead and sold them. Not going back.
Does this mean every Danny mod will work? Absolutely not. Does it mean they CAN work, even though the measurements show little if any improvements? Absolutely. So condemning everything he does without ever having actually listened to the real thing is probably not the best way to go.
Edit 1: I know Danny does not listen to them himself, because he claims to know how it sounds - which is somewhat ridiculous.
Edit 2: Dannys crossover would not fit in the box, and he clearly had not tried to make it fit. So I had to go external, adding a lot of clutter...
Edit 3: So he does not put a lot of effort in such a upgrade project (the video probably takes up more time than the rest), which I can understand from a business point of view, but not as a paying enthusiast...
