A friend of mine wishful thinking. Monkey coffin.
18”,8”and tweeter. The 8” is not gonna make the cut.
Duuuuuddddeeee! That is flipping awesome! This is such a weird coincidence, recently I have been in a super nostalgic car audio mood (happens to me from time to time but man I love to reminisce..) and just obsessing over 90s fosgate stuff. Looking at old ads, pics, installs, just falling in love all over again. Super cool!
I see you have some raw woofer parts on eBay. Seems there is really a market for people building their own subs (I find it a blast!) but the parts are hit and miss on stock at places like LOB and PSi.. with your far east connections any plans to maybe stock a whole line of that stuff? I know it’s not your target market but just curious.

It’s funny you should ask. I was just going over some of the samples I got in in the last few months. Yes I will be making a page on my website for actually speaker building. Right now I think a lot of people are doing big subwoofers for car audio SPL and I would kinda like to maybe import some stuff, so people like us can build more higher end speakers of our own.
Yes that is awesome! Biggest hurdles to that I’ve found are of course smaller baskets, but small non-sub motors, and despite several attempts in my garage, no ability to do a copper sleeve or shorting rings. Also non-sub spiders are hard to come across.
I’ve gotten some of my regular speaker cones off eBay from a place in Michigan but I think they may have folded, haven’t looked in a while..
Short story is the ability to build high end mids and woofers would be so cool and really open a whole new aspect to diy speakers! I had a lot of fun building mine, even have a pair that I wound my own coils on titanium formers from titanium sheet. They are the 8” in my avatar. Super fun.
Oh and new high end drivers are so effing expensive now that it even could be financially beneficial for the builder.
I used a different part number for the mid in my Faux Pas build (Heresy clone, but as a tower and on the cheap) crossed ~750-800hz (swapped the included horn for the Celestion H1-9040P/ Dayton H812 instead). But the response graph on the spec sheet looks identical so I'm 99% sure it is the same CD just with a different horn for the new part number.
I've got some of the PE buyout giant $4 b-52 waveguide horns (BL-409). I should see how these CDs do in those. They are certainly cheap enough to mess around with.
Used the p.audio pht-409 for the tweeter in the above mentioned build. Polyimide diaphragm, and the horn looks identical to the tweeters in the Klipsch heritage 3-ways (though Klipsch changed the phase plug in recent versions). I measured HD in the -50s. I got it as a b-52 buyout off ebay. But ZXPC.us looks to be the only US, non buyout, source for it that I can find. There seem to be very few people importing p.audio stuff.. so maybe another gap to take a peek into.
Myself being a rather uninformed outsider to PA. There seem to be no 18" monitors. Probably since folks like to have em up on poles. Though one thing I find local bands tend to lack is a sub/s. 12"/15" monitors are not tuned for that so the bass guitar barely gets heard unless there are venue subs to use. I wonder if there would be a market for a horn box with amp built in to plop on top of, and power the 18". The horn box would be smaller than a 12" or 15" monitor so maybe a band would be more open to transporting it along with 18" cabinets.

Looks like some copper on the motor. I never read that in the specs.

3rd bullet point on the feature list
TW030WA11/12/13/14 are very good performers.
I read copper clad and just assumed CCAW. I might have to keep a set for myself.

My own measurement at 2.8V aligned reasonably well with what Hificompass shows for TW030WA11.
Came in early and finished these up.

I need that access panel on my next build. Any tips for fitting the panel?
I used a poplar trim ring on the inside so screwing to it would not wear out so easy like MDF and did a 1/16 inch recess on panel for thin foam tape.

Some bracing today.

Looks like a big subwoofer nest . . .

Sub cabinet done. On to some big MMT or MTM’s.

Modifying another horn. For testing purposes

The SB CD that were $22 at madisound.
https://www.jfcomponents.com/
It looks bigger than I thought. I'm still not sure how they can build & ship that thing for under $25. Hope it measures well.
Added a little OB low-end.
https://www.jfcomponents.com/
Do you get any useful bass extension with so little baffle?
I think it does really good. Almost as good as the the Big OB’s I brought to Iowa 2022.

What drivers are you using?
MCM 55-2985 21”
https://www.jfcomponents.com/
Wow! Cool!
Remember the cone area is like 8-8’s per Subwoofer.

Check out the MCM 53-1245.

I have some horns and CD sample coming since I already have a 18” driver.
