XSD Speaker Flatpack GB

[xrk971]

Parts Express 095-522 seems to be the correct crimp connector (no plastic sheath). Nicely made with tin plating I think.

Just finished wiring one side of woofers. Used a 1.5v battery to check proper polarity by looking at motion of all cones with excitation.

Drivers installed and crossover connected.

I forgot to update this thread to show that I listened to this new XSD and it sounds great. Here is video of mono speaker played with Warp-1 Class D amp.

Measurements of the XO response shows pretty consistent with previous speaker - there is a small peak in the woofer output near the XO frequency. Probably driver to driver variability. The mid range also has a little more structure at the top end.

But overall, the sound is very lively and dynamic. Distortion is low and speaker is clean sounding. There is a distortion peak around 370Hz but level is low - it’s probably related to a cone breakup mode for this batch of drivers.

I gave the speaker a test tone (sine) at 370Hz and monitored the FFT spectrum and it shows dominant even order harmonics and circa 0.11% THD for 2.0Vrms. The even harmonics are at least pleasant sounding vs odd order.

As promised, the packing is progressing nicely but is a lot of work. You can see how carefully the pieces are packed in foam and strapping and then a nice box and then strapped on the outside.

Folks should be receiving tracking numbers soon.

"X", What is the approximate box shipping size? I live within 100 miles of Leoanard, TX and would consider a direct pickup with my little car - if possible.

 

[xrk971]

If you come in a car no box needed as it is oversized. Longest piece is 45in I think. So all stacked up about 4ft x 2ft x 1ft volume. It weighs like 50lbs though.

Are these still available with walnut?

I mentioned the other day I had picked up on sale, another pair of the midranges "just in case" right? I just did the same with the tweeter. I'm fooling myself, I'm getting ready to build another set aren't I? Oh brother....

[Bearforce One]

Yes, yes you are

 

[xrk971]

Are these still available with walnut?

Russellc

Yes I think so. Let me check. But we can get an order set cut if there was interest.

 

[xrk971]

Yes, we have a walnut xsd flat pack in stock.

Where would you put the second set? That’s a nice testament when someone wants to build a second set.

It´s sad I can´t get the flatpack here in Europe

 

[Russellc]

That is. Without the flat pack, I would still be staring at the parts!

[xrk971]

You can. A member in Denmark had me ship them to him using a freight service I mentioned earlier in the thread. It was very reasonable.

 

[Quirepace]

Hi, How do i place an order to be shipped to the UK?

 

[xrk971]

@dawa : what was the carrier service you used to ship XSD from USA to EU?

Thanks.

@Quirepace : we sold the last walnut flatpack but can make more if you are serious.
