tresch, nice work, very interesting.
I'd like to see raw drivers measurements, without crossover.

unfortunately my roomie is a little protective of these guys and I probably won't be able to drag one out for more measurements any time soon.
I can say that from listening impressions at least the off-axis response is very good.
I could have gotten some measurements of the woofer by itself the the tweeter is very much permanently attached to the enclosure and there'd no good way I could have pulled it out for testing without probably damaging something. 🙁

I meant measurements taken without removing drivers from enclosure.
just bypassing crossover. that way we could see how crossover functions.

Can you elaborate? How is the microphone connected to the sound card? I have one of these and ultimately would like to test my speakers.
BTW, nice work!
TIA,

There is actually measurements done by someone.. http://www.audioxpress.com/reviews/media/AX201DA.pdf
hi,
i got the same speakers. I added a sub (css sdx15, dayton hpsa500, ported) to it and the sound has improved a lot. it does a better job if relieved of doing the lower frequencies.
Any one here has any recommendations as to how to improve the sq of 602s.

how much would i need to spend in diy speakers (drivers and crossover costs) to beat these speakers. Any suggested designs that are clearly superior to these. looking to upgrade mine.😀
It's never that simple- it comes down to personal taste, in most instances. For example, I'd take a set of Pioneer B20s in big TLs over this type of speaker, anyday. Driver cost of mine, including the supertweeter and XO for the supertweeter, is a whopping $35 or so per. But, there's a lot of work, and you can run up the bill on cabinet materials and finishing easily enough.
But, like I say, that might not be to your taste. There are a number of designs like those at Zaph Audio that are as mature. The B&Ws hot tweeter would be an easy fix, a little extra padding. The upward tilt indicates a tuning that would stand out in a hifi shop, a very common failing of commercial speakers- they're made to sell, not to satisfy (duh!).
Hi,
Yuo have to take some toime ans effort on the cabinets and possibly
a little inventive for lowest cabinet colouration and then carefully
choose what sort of design you want.

the B&Ws are solid speakers, but they're certainly not perfect. It's a very standard 2nd order crossover fairly solidly in the middle of the vocal range, and I think this is their greatest weakness. The couple full-range speakers I've built outshine the 602s dramatically in the vocals.
In other aspects, they're pretty fantastic all-around speakers. They're ported, which I don't really like, but as far as ported boxes go they're well tuned. The cabinets themselves are very ho-hum. cheap chip-board without a lot of bracing. B&W speaks of lots of their cabinet technology in their promo vids, but very little of it is to be seen here.
So.. there's a lot of directions you can go obviously depending on what your listening preferences are and also what levels of loudness you're looking for. Care to give us a little more input in those regards?

I usually listen to classic rock, blues, jazz, metal, classical, indian classical in that order. these would be used in a home theater system also for movies. I already have a sub, so low end is not a problem. Currently the amp is yamaha rxv-663, but some time later I am going to get an integrated amp for music. My focus is speakers for music, movies dont matter, i will live with however it sounds for movies. I would prefer neutral to warmish speakers, non-fatiguing. Dont blast too often, so excessive sound levels are not needed.
I am already planning to use some sort of full ranger (maybe with some cheapo tweeter) for my desktop system. this one i want it to be a 2-way, preferrably bookshelf (can be a large bookshelf like 602). Some time later, when I have more cash, I want to make some really good speakers, in the mean time, looking to better these at not too much of a price. I am looking to invest the most in the drivers at this point. I can try to make a crossovers with cheaper capacitors and resistors available locally, these I can easily upgrade to better ones later when budget allows. inductors are i think expensive everywhere in the world🙁
I have zero woodworking skills, and I dont think my current carpenter can handle anything more than a sealed or ported, so horns and TLs are ruled out.
