On the CNC issue, what controller and software are you using for the gcode? I had a random estop issue appear and go away, and it started happening after I swapped out the battery on the motherboard of the comp. It turns out I had a corrupted Ma…

Thinking about outdoor speakers as well. Saw these. Got me wondering if they'd be worth a try for $500 a pair. 10" woofer +1-3/8" Ti compression driver. https://www.harmanaudio.com/jbl/TOWERXMARINEMT10HLW.html

I have the X3600H, and about a month ago, after some power outages happened, the receiver has gone randomly into protect mode when listening to any source. I've had to "reboot" it to get it to work, and it would work for 2-8hours over the…

So here is my distortion measurement. Never done this before, so let me know if I should do anything differently. Also, 1.8kHz 4th order on tweet and 2nd 1.8kHz on woofer for reference. (Image)

I bought mine off Vance so I actually have this pair in test bench... Obviously distortion graphs available in the article. https://audioxpress.com/article/test-bench-the-new-6-wf152bd09-04-midbass-driver-from-wavecor Second distortion source.... …

Washington DC area. Happy cinco de Mayo to all. Thank you Augerpro....this is your TW29tx step file cut on the cnc.

Went the waveguide route, all wavecor. Really wish I was close to someone that could measure this combo. (Image)

(Image) Of course I had to find this combo.... https://www.hifitest.de/test/lautsprecherbausaetze/lautsprechershop-neo-kyma-23145

I do have two pairs of TW030WA03_04 OEM tweets if I want to keep all Wavecor. Thought about a shallow waveguide in the front baffle and rear mounting them. I'm looking at directivities. I wonder though, do I need to worry about a waveguide at 22…

So I decided to tackle a project to make a plant stand woofer box, or possibly the bottom end of a 3way. I wanted to compare sealed, ported, and bandpass arrangements before finalizing the design, but I didn't want to build a bunch of boxes, so I d…

I noticed the new LW5004 measurements. Couple of observations. The directivity looks very wide out to 3kHz. Is it that big dustcap making for a wider directivity at the upper frequency range? Also, I'm thinking that the 2.83V annotation in this…

RESTOCKED Wavecor SW270WA01 10-1/2" Balanced Drive Paper Cone Subwoofer 4 Ohm Part #88-298-1072 Per item price : $88.00 - $75 with code.....going to kick myself for not buying it I bet. https://www.parts-express.com/RESTOCKED-Wavecor-SW270WA01…

Relatively easy experiment for anyone to try. Take a 2 litre bottle and put a 3-4" speaker on the big end. Measure with bottle cap on, cap off, and balloon inflated inside using up 1/2 the volume. You should have a 2l ported, 2l sealed , and…

Yes, you effectively have two springs. If the bladder is inflated to 1 psig, and the box is pressured to 0.001 psig, the bladder volume will change very little. It's like a ballpoint pen spring on top of a car strut spring. Compress the ballpoint s…

JR, you know you need matching subs for the 3-way right? (Image)

Here are my thoughts. The air volume inside the cabinet is a damper, like a shock absorber. While sound can pass through the rubber membrane, the air itself cannot, therefore it will effectively reduce the air volume needing to be compressed by th…

Check out Michael C. He has done 4 8"/3" variants, one with the Hivi sealed. Hits 51hz F3 sealed... Based on DATS https://ampslab-spk.com/

FWIW, the sealed in-room response graphs are shown in the thread....in-room response graphs look to be getting pretty close to 50 Hz. (Image)

rs225 is lauded as "special" in this WAW build thread. https://diyaudio.com/community/threads/10f-8424-rs225-8-fast-waw-ref-monitor.273524/

Two thoughts: Find the manufacturer of your current coil, and see what the DCR is on a 0.6mH coil by them with the same awg, and if you have an ohm meter, unwind until you hit that DCR. use a calculator to approximate the number of turns needed af…

Hey Nick....How does the ESS sound? Would you elaborate on why you picked front mounted PR and rear port over the other possible combos of locations?

How about monoprice encore t5 tower for $89 and free shipping? https://www.monoprice.com/product?p_id=43152

What CAM software are you using? Does it automatically make the tabs?

I picked up 6 about three years ago at $21.21 each. Then they went OS and came back. They seem to drop the dynavox prices on occasion, at steep discounts.

How bout that Dynavox LW5004 for $26.26 over at Newark. Two with the Aerial Seas Tweet in a MTM? https://www.newark.com/dynavox/lw5004pmr-nm01/5-25-pp-mica-woofer-80-watt-6/dp/78Y7663
