How are these subs with just a simple 80hz XO like what is typically in receivers? Do the higher frequency resonances cause too much issue, requiring an EQ?

you really need a HPF to cut below 20-25Hz on these per the OP

the receiver LFE setting should take care of everything else above 80 or wherever you set it

Agreed- these little THs do a good job to surprisingly low, but will make decidedly unhappy noises if you don't protect them from the deepest LFE.

Nicely done Sibuna.

Does anyone know if I can use the minidsp to limit the amount of power that my speakers receive? I'm looking at possibly getting an EP4000 now for some future upgrades, but wondered if I could run my 2 anarchy tapped horns off of it...without melting them of course.

The Behringer iNuke DSP models will do voltage limiting.

yea im using one for that reason, I got the 1000 DSP which does 150x2 @ 8 ohms, i have it set to ~120 right now

if you wanted to grab a 3000 or 6000 DSP model for future proofing you could do the same limiting with them on these guys without fear of killing them

Not a bad idea, I just hate the idea of getting another DSP having just bought the minidsp not all that long ago. Would the NU1000 (non dsp version) at ~150w x 2 still be too much?

Well, not long signed up to this site, been looking for a while tho. I'd like to be able to build this horn as my first foray into all this but i dont have the permission to download the pdf. Never mind. Just like to say ive tried hornresp, and it is getting on my goat, very frustrating. Tried to input my driver specs but still get confused. I aint stupid but it sure feels like i am. Anyway, i plan on a horn build for my tv system, and will surely be getting plans for some Bill M stuff for outside. i take my hat off to all and sundry who have built horns and admire those who can use hornresp. If i could, i'd love to be able to model a woofer i have just to see if it could work in a horn. Please, can anyone tell me if i need to use hornresp to model the driver, then use this sketchup to design it? is that the way she goes? Sorry, just trying to clarify, im doing my best and will not be happy at all until i have a grasp on all this. I know this is off topic so my apologies to the old faithful. I admit i am getting desperate lol. And if anyone is interested the driver i have is a pioneer tsw 309 d4, have 2 actually, sittin around doing nothin, would love to put them to use doing something, anything. Thanks and apologies once again.

Does this horn need a steeper low pass filter than 12db/octave? I am concerned about the big peak near 110hz, here's what Hornresp shows:

I love these subs so much I purchased a second pair. The first pair is operational, but unfinished. The second pair, also operational, is near to being finished in Duratex. At that time, they will be switched for the first pair so that pair can be finished in Duratex.

With help from "Lilmike" I modified two used Dayton 240 plate amps. One worked flawlessly, but one did not work properly. A call to Parts Express (PE) brought advice to send it to PE, which I did. An accompanying note described the history and requested help, authorizing the tech to dispose of it if not fixable or worth fixing.

Shortly thereafter I received an email advising the unit was repaired. I need only pay $11.46, the return shipping cost. The amp now works perfectly.

PE is a great company with which to do business. Send most companies a defective, discontinued, modified product that had been purchased used and they would suggest an unnatural act for you and the product. PE is a great asset to the DIY fraternity.

What is the cost on the drivers for these?

Total cost of the project?

I need a sub for my PC.

Driver: ~$74 from diysoundgroup.com
Sheet of 1/2" Plywood (sandply): ~$40 from HD
Glue, Stain/paint, finishing: ~30
Amp: Dayton SA100 $90 here at parts express
HPF for 20 HZ: $25 from parts express
Total: 258

I don';t have any experience with the FMOD's yet. Maybe someone else will chime in regarding a HPF option.

The spa 100 plate amp should already have an hpf built in I believe

I can't seem to find any info on whether it does or doesn't. I don't think it matters for most setups, but the guys here are strongly recommending a HPF for this driver.
