Is this going to sit on a table or a desk? If so, you might not need much BSC. I had Madisound design a crossover for the first first (decent) speakers I built many moons ago. I didn't know enough back then to ask them to include any BSC. They sounded a little thin as a stand mounted design, but they sound much better on my desk, raised up on little risers.

It's going to be portable and I plan on selling it. I'm just learning so will trust your guy's judgment and will play around with whatever is necessary.
That's a good sim, as far as that goes. But... It doesn't look like baffle effects are accounted for.
Well shit..... what do I do for that? I didn't see anything about doing that....
If you press the button in PCD for "raw driver response", you can see what the woofer series inductor is doing. You will typically want about a 3dB difference - but that depends on the placement of the speaker and your preference. I often will "knock out" a quick sim in PCD to get me in the ballpark, but my process ongoing is to then measure the drivers in the intended box at about 26 inches or so, and import that into Xsim for tweaking. But there are many different process variations in our community.
But Chahly - Stahkist don't want speakers that look good, Stahkist wants speakers that sound good!
Awesome! Thanks Don! I think I'll fiddle a bit and then make the xover. I'm not crazy concerned but want to learn and make sure it's pleasant sounding. If these were bookshelves/towers I would definitely be more picky.
Build in a hump from about 800 and below rising about 6db in the response... That's for about a 8-9 inch baffle. Smaller baffle in width, you need to start higher.
Using a baffle step simulator like the edge or Jeff's boundary simulator will help you understand what's it doing...
6db is full Bsc, while for a desktop speaker or something closer to the walls 3-4 db is good enough
6db is full bsc, speaker out in the middle of the room (4-6 feet from the back/side walls), tweeter at ear level - this is what the usual floor standers made for DIY event auditions go for - I don't have that kind of space, so i aim for about 4db. On the desk, might be tad lower say around 3db or use the EQ to compensate for bass (lower it for on Desk application or where it sounds good and not overpowering).
full BSC, but doesn't matter, as there will be no bass either way.... Outdoors is a different matter altogether, you need some sort of a room for bass enforcement
But let me also clarify by saying my experience of speakers outdoors have been underwhelming and i have not done or explored outdoor speakers much....
Hey Joey, if you're leaning towards the LD22, we still have some of the plastic faceplate versions on clearance on our website for $45. If you end up ordering them, and you want them disassembled, shoot us an email at [email protected] and we'll make sure the faceplates are separate.

Awesome! Dan, lmk how to proceed, when I go to the website it shows them sold out. Thanks!

Well, my helium based BT doesnt do too bad of a job and I'm guessing that has full bsc..... guess maybe go with it...

I pulled some strings and there's a couple more in stock now 😉.
So confused about BSC in PCD.... why is my summed response going down for the woofer? Shouldn't it be going up?
BSC takes away from the raw driver SPL. So 3dB of BSC makes an 87dB driver into 84dB. Not sure about your summed response question. Can you post the graph pics?

You don't need a separate BSC filter. Take it out completely and just play with the lowpass inductor until you drop the highs sufficiently to be in line with the 200Hz-ish mark. Then play with your shunt cap to get the knee you want. A single inductor and cap on a woofer is very versatile and usually sufficient for BSC and desired rolloff.

Thanks!
1. How do I know the attenuation necessary?
2. Where in PCD am I adding this in?
3. Is it necessary for this?
Thanks!!

(Well, with 2 more paper riavels)
Seriously take care of your crew first. Appreciate you being a part of the community
