Someone here should grab these.

@zerodeefex too bad I missed meeting you when you were here.

@Poleepkwa yeah, the new cabinets are way more “domestic” :)

^^^ @shotgunshane? Bueller? :)

PM sent. I owned the zx2 way too long ago for a reasonable comparison but sent you some general thoughts.

For what it's worth, I did not like PAW 5000.

Only one or a pair?

I think this is going to @spwath. I was assuming no one would want the busted one of the pair (see the FR graph a ways down at https://imgur.com/a/w0gTNxC).

Oh man that's pretty bad

Link isn't working for me

Looks nice. Some time I'll build new cabinets for my speakers, they are a bit too small, and carpeted speakers are ugly.

Looking great, nice job!

Please show some pictures how it turned out.

Cat is more of a planar fan

@Poleepkwa will do

@bixby Had a similar experience. Dude shipped me a 30+ pound commercial coffee grinder in a box that was too big with only crumpled up newspaper around it. When I received it the top was sticking out of the torn box.

@philipmorgan Bummer, man. Always so disappointing to have to deal with stuff like that.

Whelp, the damage is definitely more than superficial damage to the one driver's magnet. FR plots: https://imgur.com/lsHKPDQ

Yours?

Yeah

You get used to it. Everything under 12" feels "petite".

Chi-fi is not cheap

Might be overpriced, look at Audio Nirvana classic ferrite 12 inchers.

I find it interesting how much more expensive the 10’s are than every other speaker in their line. It’s the same on Taobao. They are actually more expensive than on Amazon US. $330 USD each!

EH6922 is a nice new tube. Can’t beat it for its $20.

Thanks Bazeleo. Bought ‘em.

I'm a big fan of the GE 5670 which are adaptable to most 6922/6DJ8 applications, especially the older D getter ones. Not quite as tight of a low end as most NOS 6922 but really lovely air and soundstage, and can be found cheap with a bit of patience

No, sorry. Otherwise I woud have been more than willing to let you borrow it.

I have one you can borrow. Never used it yet.

Thanks JK!

@spwath thanks in advance! I'll PM you about that in a week or two.

My life is boring. I just took a picture of a barcode.

Is this for that Decware amp?

Yeah, it is for that amp. I've got the board fully populated, now just waiting on the transformers to arrive.

Prolly will start a thread for the build when I've got more to show since there's not much info out there about this amp.

I thought you finished your system

Got a bug to make different bass cabinets. Going low and fat with the shape instead of tall & skinny. And sealed...

Gateway drug, isn't it? Before you know it I'll have $200 worth of Jupiters on a $300 amp. :-|

When you want reliable results (esp in case of high mech Q bass drivers with some impedance swing) you'd be better of with scope than DMMs. A current probe inline (just a resistor can do), voltage across it and voltage bw terminals. You need two channels. Then you can get phase difference out and calc real and reactive power in each freq point.

When using scope be sure that the amp output is either truly floating or (-) is ground referenced, where you connect your probe ground. Otherwise: white smoke!

I think I’ll try a DMM for now, but a picoscope is in the horizon. Hopefully without white smoke :)

I haven't encountered any finished DIY designs which I would consider repeatable. The theory behind a successful implementation seems very complex.

I'd also recommend reading up Earl Geddes stuff on horns/waveguides, he has some plausible points on horn implementation negative points.

Thanks for that pointer @Hrodulf http://www.gedlee.com/Papers/papers.aspx

@Cspirou the avegant glyph is quite good for the "bit screen anywhere" use case.

@zerodeefex - thanks! I'll read up on it. I see they are $200 on Newegg right now

@Cspirou that is the right price. More would be too much given the limitations. If you do pick one up, experiment with ALL the nose pieces and settings then take a while to dial in each eye. Once it's set up it's like a portable projector beaming into your retinas.

I thought signups were disabled again because when it was lifted, a rando made a poop in the thread literally about randos making too much noise?

Return of the dislike button may have something to do with it as well.

Also employment of extra sarcasm and mockery was quite amusing. @JK47 thank you for the extra entertainment.

Did NOT know this was a thing until you posted, looks awesome!

Would anyone agree this is a good project for someone with, er, basic elective-level DIY skills and too cheap to get one prebuilt from Decware?

If you understand the risk of dealing with potentially heart-stopping voltages, then I'd characterize it as a pretty simple build. I haven't actually built it yet, but from reviewing the docs I'd rate it at about 2 on a 5-point difficulty scale. No surface-mount components, relatively relaxed component spacing, etc. In US prices, the BOM totals to $285.26, so a pretty strong value if the sound is decent.

The low BOM and corresponding high-value potential is exactly why this caught my eye, haha. Other hobbies + school mean that I can't quite splurge on audio as much as I want, but given how many people love (the) Crack, I'm tempted.

As for the voltage thing... aye, this is gonna be fun :P
