About the Cabinet

This particular cabinet is designed specifically for the Dayton Audio 18" Reference Series High Output subwoofer, but works for any subwoofer with an overall diameter of 18-3/16" or less, and a cutout requirement of 16-3/4" or less. The sealed enclosure design creates a subwoofer system with a Qtc of 0.644 and an f3 of 40 Hz when used with the Dayton Audio RSS460HO-4 and minimal fill. Adding five pounds of Acousta-Stuf will create a critically damped subwoofer system.

During the CNC manufacturing process, rabbets dadoes are cut into the back panel for precise panel alignment. A unique two-piece brace adds superior rigidity without affecting the subwoofer's performance. Both side panels feature 3/4" rabbeted extensions with recesses to perfectly install the first piece of the two-part, double thick baffle. Plate amplifier installation is made easy by following the scribed interior guide with a jig saw and by modifying one of the braces.

The end result is a resonance-free, sealed subwoofer cabinet that is purpose-built to extract the best performance from Dayton Audio's 18" High Output Reference Series subwoofer. All that's left to do is finish it to match your décor or paint it to stand out. When your friends ask about it, you get the pleasure of saying, "I built it myself!"

Specifications: • Panel thickness: 3/4", front baffle is 1-1/2" • Panel material: Medium Density Fiberboard (MDF) • Finished net cabinet volume (subtracting the double thick baffle and bracing): 4.0 cubic feet • External dimensions: 23" H x 20" W x 20.75" D • Subwoofer recess: 1/2" • Weight: 62 lbs. • Made in the U.S.A.

About the Subwoofer

The Dayton Audio Reference Series subwoofers take the quality and performance of the much acclaimed RS line into the subwoofer realm. As with the rest of the Reference Series, the main focus of these subwoofers is ultra-low-distortion. Second, third, and intemodulation distortion are kept extremely low by utilizing three short-circuit paths within the motor structure.

A durable aramid fiber spider and extensive venting throughout provide quiet and uniform excursion. The black anodized cone, rubber surround, and custom basket give this driver a unique, high-end look.

Dayton Audio 18" Reference Series HO Subwoofer and Cabinet Bundle
Dayton Audio 18" Reference Series HO Subwoofer and Cabinet Bundle is rated 4.7143 out of 5 by 7.
Rated 5 out of 5 by from 18" Sun bundel. "Heavey Hitter"The package only took 4 days to get here and I had it together in a few hours. Sanding and painting took a few more. I let everything dry over night and installed the "beast" 18 the next morning. I used 4.5 pounds of audio fill because I wanted it to be somewhat over damped so it would be fast enough to keep up with my Magnepan 20.1 full range ribbon system. Long story short this 18" beast is fast, musical and high detail. It fills the last octave down to the lowest note. I am not looking for kick you out the window bass buy it will do just that if you have a big enough amp for it, I do and I did test it on some very heavy rock to see what it could do. I moved all the walls in my 19 ' x 26' x 11' room. I have it crossed over at 30 Hz at 12 db slope. The Magnepans are 2 db down at 24 Hz and the "beast" takes the sound to the basement from there. If you need big bass and have the room for it, you can't go wrong with this sub. You could not equal this sub in a factory built unit for less than $5000. That is the truth as I was a high end audio dealer for a number of years and the only sub that could keep up with this one was a JBL B360, 18" proted 11.5 qft box. It was the size of a small refrigerator and tipped the scale at 345 lbs. If you need top quality bass and are willing to do a little work this bad boy has your name written all over it. Sound systems are not "one size fits all". Audio has gotten so pricy that the only way to put together a first class sound system is to build it yourself and the money you save you can put into music to listen to. DIY is the American Way and Parts Express can make it happen.

Rated 5 out of 5 by from Great project, great bassTitle says it all, the flat pack is really well cut and goes together very nicely with minimal sanding to make it perfectly smooth. 24" clamps fit fine, 6 to 8 is ideal. I used regular LePage wood glue and 1.5" brad nails w/ air compressor. Finished it with a textured black and white spray paint.I'm using the sub with a miniDSP 2x4 for crossover and eq, powered by an old Carver power amp. The sub is in a big open room in my basement on concrete floor and the bass out of it is incredible, it's super deep and solid. Great project!

Rated 4 out of 5 by from Evil BassI bought two of these kits and have installed both in a ford explorer. Its loud and sounds good. It feels great, but too loud to be good for ears. But so addicting to turn up loud, its an evil combo....
Date published: 2015-06-24
Rated 5 out of 5 by from Love it!I purchased this combo. The CNC box is very nice almost no sanding at all. The subwoofer is a beast. Still dialing it in with the stuffing and the Crown XLS-1000. I had to get the art box line leveler to get any volume out of it though so be warned if ur using this pro amp in a home theater setting. Otherwise lovin it a lot. Glad I wEnt 18 instead of 15 inch. Never been unhappy with PARTS EXPRESS OR DAYTON AUDIO.

Rated 5 out of 5 by from Fun to assemble and EXCELLENT result!My first DIY sub, if I can really call it DIY, because the hardest part is already done by Erich, the supplier of the cabinet flat pack.No need for cutting panels or even trimming edges, this cabinet is precision CNC cut so just glue it up and your golden.I stuffed a polyfill pillow inside the finished cabinet before I fastened the 18" driver in (flush mounted, no less), connected it to my Behringer iNuke 3000DSP (also from PE) and this combo hits, and hits hard.I've had several quality internet-direct subs in the past and I would estimate that you'd need to spend $1000+ to get this kind of performance.And it was a fun project!(And yes, you really can assemble this sub with wood glue and masking tape.)

Rated 4 out of 5 by from Nice. And heavy.I bought this as an upgrade from the 12" reference series powered sub from P-E, which is a very clean sub. I like how it sounds, even though I don't have it 'dialed in' yet. I will be using this with the P-E TriTrix speakers in a tri-amped configuration with this one mono sub, a Behringer 2496 digital x-over and some Crown DC300a amps for hi-mid and a McIntosh MC2200 in mono mode for the sub. (I eventually hope to upgrade to the Sure IR 250 class-D modules for power).The box pieces fit together almost perfectly thanks to the CNC precision cuts. I quickly ran out of gluing clamps and improvised a strap clamp. This box takes a lot of glue, and it has to be applied and fitted quickly before it begins to dry. I used Gorilla Wood Glue.I was disappointed that the front baffle is not a one-piece 1.5" baffle, but is actually 2 x 3/4" pieces that have to be glued together. That's a lot of surface area to glue and clamp in a hurry. The glue began drying before I could get everything properly coated, and so my baffle has some minute gaps between the 2 layers, but it seems to be solid and rattle-free. I wish this kit had screws like the TriTrix kit. That would make it easier to assemble and glue, and reduces the need for clamps. I'm not a woodworker, but I managed.Mounting holes for the 18" driver have to land where there is no interference from the internal braces, leaving room for a T-nut at all 8 positions. A couple of test fits and a pencil took care of this. I used Scotch 77 Spray Mount for the fiber filling. I drilled a 1/4" hole for a 14-guage cable in the middle of the back plate.I am currently powering this with one channel of a Crown DC300a and it really kicks. When I play some of my home studio recordings through it I can feel and hear the accidental footsteps that were recorded along with acoustic guitar. Very realistic. No rattles or whistles or anything but clean and full low end. I like it and I am glad I bought it.

Will this kit allow enough room to install the 1000 watt dayton plate amp in the back of the enclosure 

Asked by: gridlock
Yes this has room to install a plate amp in the back.

What amp do I use to power this? I will use it for home theater. Can I use this? Yung SD300 300W Class D Subwoofer Plate Amplifier Module No Boost Part # 301-508

Asked by: cjtuason
The SD300 will power this, but you really want some headroom for a subwoofer this big. I would recommend no less than 500 watts RMS, and 1000 watts would be even better.

Is there much difference between this and the Ultimax 18" knock-down bundle with the same cabinet, for general audio/video use at home? Would they sound pretty similar?

Asked by: RJCC
There will be very little difference between the two in terms of actual in-room response. The Ultimax will have a slight edge with output and extension, but it is still negligible.

Is clamps necessary to build this cabinet? If I need clamps how many, and what size is necessary?  Also, is a speaker terminal cup included?

Asked by: Adam112
Clamps are recommended. I would recommend a minimum of two 24" clamps, but you can use as many as you want depending on how quickly you want to assemble it. Terminal cups are not included.

Would stuffing the cabinet with ~ 4lbs polyfill stuffing bring the Q down to around .5?

Asked by: starhopper
A heavily stuffed enclosure will have a Q of 0.56 in this case.
