My personal criteria require higher output with low distortions, and preferably better control of directivity at lower frequencies, than what current coax speakers (drive units) can provide. As usual, it is a compromise, and we all choose depending on what matters to us individually.The Coax from Genelec Ones and newer KEF minimised these trade offs (e.g. no edge reflections and very wide and smooth tweeter radiation).
Thanks! i did my best on the paint.The cabinet looks well finished. So you’re running only one sub?
Nice setupA DIY high end subwoofer is not that complex if you want to learn, use good woofers and amps with dsp.
It looks fun to me to make a closed dual opposed subwoofer with 12 inch Scan Speak discovery drivers and FA501 Hypex amp.
The sub has a way better sound, spl and looks than i was expecting when i started the project, i compared it to the SVS SB2000 in REW.
Red line is the SVS (with peerless XXLS driver) 23hz+-3db, and green the dual Scan Speak tuned 22hz+-3db
The sub looks a lot like the Arendal 1723 2S but smaller in al directions.
Making a sturdy box was easy for me i have a lot of tools and experience, the paint job was the hardest part to do for me.
I think for a DIY subwoofer only dual 12 or single 15 or better give you more bang for buck than brand subwoofers.
Its hard to make a better DIY sub than an SVS sb3000 or Arendal 1961 S / 1723 1S for way less money.
To make my sub with new components it cost only in that 1250 euro, without MDF, paint, wool and a calibration mic.
It cost almost the same as the Arendal 1723 1S and it has the same SPl when i put my sub in speakerboxlite with 400 watt@2ohm.
But for me it was worth it, i enjoy the whole proces and the sound of the subwoofer even more.
Speakerboxlite says my sub with 60 liter and 400 watt has 8.3mm one way cone displacement @20hz, with 2 woofers in one box its the same output as one 12 inch woofer that has 33,2mm one way cone displacement thats insane for a 12 inch driver.
The JL Audio E112 has 38mm one way cone displacement and need 1500 watt to do that.
Dual opposed design is a good way to make a DIY subwoofer, even with not that much amp power.

Thx, i like Arendal speakers a lot i have a 1961 series atmos 5.1.2 setup from them, only the sub is DIY.Nice setup
Speaking of which, I own two Arendal 1723 Subwoofer 1 subs. I wanted to build 15" bass legs between my 2-way mains and the subs, to give more performance below mid-range and above subwoofer range. So I got a pair of 15 inchers, put them on 80 l boxes and fired up the DSP and some NC400's. The total cost was a little more than what went into the Arendal subs.
Even expensive speakers have cut corners (lol not an Arendal pun) to save costs. When you put some money into where it counts, you get best results. In subwoofers I'd recommend looking at large pro drivers. I bet your system will best any similarly priced commercial. At least I was surprised what these Eighteen sound woofers can do. And my Arendals are now for sale.
Yeah but that's super uglyView attachment 340577
Chimaera double 15 1 used as active reflex 1 mid hornloaded 1 tweeter
Quadriamplification powersoft with dsp 1000w x Chanell 4 Chanell per speaker, 125db+ of output with low distortion, what do you want more?
Looks like a stackable washer/dryer, with a microwave oven on topYeah but that's super ugly
design me a speaker like that i want to see where you put the horn and the double 15Yeah but that's super ugly

I'll pass they all look ugly.design me a speaker like that i want to see where you put the horn and the double 15
Horns are not mend to look nice but DUOs were never about looks.Avantgarde Acoustic showed how to package something like this nicely 30 years ago.
The DUO PRIMO XD with the horn-loaded bass range with 2 x 12" bass drivers should put the 2 x 15" in the shade.
Endgame, but unfortunately not DIY.
"Horns" vs. "hORNS"?Horns are not mend to look nice but DUOs were never about looks.
Finish and the rest are really good but looks was never mend to integrate with nice living rooms.
hORNS on the other hand is an entirely different story,I know people that would put them as a unit in their rooms.just for the looks,without music.
