Overnight Sensations MT Speaker Kit Pair

When Paul Carmody first listened to the Overnight Sensations speakers that he designed he exclaimed, "I wish I had a time machine. I would go back to my bedroom when I was in Jr. High or High School and give these to myself. These are the little bookshelf speakers I imagined I had: huge soundstage, deep bass, and tiny box. In reality, back then all I had were some impish Minimus-7s."

The Overnight Sensations are designed to be a quick, economical build that could put out a surprisingly-big sound in a small box. Could be a weekender project for an addict, a gift for a teenager (see above), or—in Paul's case—a set of small, full-bodied monitors that he could listen to while grading papers.

To start a do-it-yourselfer off right, this kit includes a pair of high-grade 1/2" Baltic birch cabinets that have been precisely CNC cut and rabbeted for perfect fit-and-finish when assembling the cabinet, as well as perfect driver fit.

For the Overnight Sensations' driver arrangement, Paul selected the versatile Dayton Audio ND20FA-6 3/4" neodymium silk dome tweeter and mated it to the attractive HiVi B4N 4" aluminum midbass woofer. To extract as much bass as possible, Paul decided upon a cabinet size of roughly 0.16 cubic feet (4.5 liters) and is tuned to 53 Hz using a 1-3/8" diameter port that is 6" long.

This kit includes nearly everything you need to build a top-notch pair of speakers in no time flat, including: a pair of knock-down cabinets, drivers, ports, and crossover components.

Note: Screws, binding posts, and speaker wire are not included, but recommendations are featured in the Related Products section on the right.

Overnight Sensations MT Speaker Kit Pair is rated 4.7833 out of 5 by 60.
Rated 5 out of 5 by from Nice!This is my first speaker project and I'm fairly happy with the results. The kit is very well thought out and an extremely good value.Take your time, especially on the woodwork and you'll have an awesome set of small speakers.For the glue squeeze out, my suggestion would be to go sparingly and scrape the excess off after it dries just a bit. This way you won't risk smearing the excess wet glue into the grain of the wood where it won't accept stain. Google around a bit and you'll find tutorials on that.The finish I put on - medium stain and sprayed on Shellac, is not all that smooth...may tweak it a bit by coating it with something else.Everything already mentioned about outstanding sound quality is absolutely true - they are astounding for such a small inexpensive kit speaker.This set is for surrounds in my main music/media system.I'll be ordering a 2nd set soon for extension speakers in another room.

Rated 5 out of 5 by from Great sounding little speaker...This speakers set is the best kit you can buy to start in the speaker building hobby. For new comers, it will take you all the way from gluing, sanding, preparing wood for painting, all the way to soldering the crossover and adjusting the bass response and much more... It doesn't have step by step instructions (unless you look into the website) so you have to be very creative and be prepared to read and educate yourself to become "speakers builder expert". In my case I finished the wood with gloss black auto paint, the crossover was soldered into a proto board with euro connectors and the front face board is removable for future access and sealed with black rubber(this is an acoustic experiment from my part) and stainless steel screws. The final product looks and sounds as good as more expensive sets, giving you a good reason to be proud of your project. I recommend this kit for its value and sound, my recommendation is to place them in a bookshelf, office areas as well as in bed rooms, kitchens, etc. I'm including some photos of my finished project. Enjoy...

Rated 5 out of 5 by from Great KitI had a lot of fun building these. I spent a lot of time on the cabinet; sanded it smooth as glass with a random orbit sander and stained the boxes with red mahogany to match my office furniture. I then put several coats of satin poly on, sanding in-between coats. These boxes are furniture grade; very pretty.Assembly was pretty easy. I have an electronics background, so building the crossover was a piece of cake. And I'm an experienced woodworker, so the cabinets were east too. Anyone who is fairly good with tools should be able to handle this project. Needed tools are a power sander, soldering iron, hot glue gun, and clamps for gluing up the boxes. The trick is to take your time and not rush them.For speaker terminals, I used some terminal blocks from Micca speakers that I installed the crossover upgrade in. They worked fine.These really sound excellent, with much better bass than the size would suggest. They sound fine for music even without a sub. They are small speakers and are not going to get super loud; but great for a bedroom, office, or small living room.I have attached a couple of pics so you can see how they turned out. They go to my office tomorrow.

Rated 5 out of 5 by from You will need a real amplifierSpent many years in a previous life working in major studios, was looking for a budget version of the Yamaha NS10 for my home studio. I'm very happy with these speakers. I'm very comfortable with woodworking and electronics so no issue there, but I wonder how many buyers have on hand the big clamps shown in the video to glue the panels together.Another reviewer mentioned the Lepai 20-20 as a good pairing but don't waste your time or money on it. I'll be testing the PE "no hassle return policy" on that little toy. I'm a big PE fan and I trust their judgement on most things, but the laws of physics still apply. You're not going to get 40 watts (20 per channel) out of an amp that weighs about as much as my iphone with a power supply the size of a cell phone charger.I hooked up my Carver PM 600 to the speakers and got exactly what I hoped for. Yes I know that's way more power than the OSs are rated for but if you know how to attenuate properly the speakers will handle it just fine and the headroom is a beautiful thing. Replacement drivers are $15 and PE gets me what I want usually next day even with standard shipping.I actually had to stuff some foam in the ports to reduce the bass response. These little guys fill my music room really well, my wife is complaining already.

Rated 5 out of 5 by from OutstandingI built these about a month ago and they are wonderful. I did an A/B test with a pair of Klipsch B-10 speakers which are almost exactly the same size and these killed it.In a nutshell, the Overnight Sensations were able to resolve the difference between a CD (44.1 kHz / 16 bit ) ripped to a FLAC file and a (96 kHz /24 bit) FLAC download in such a way that it I now have to replace my entire audio collection with Hi Rez downloads. Thanks a lot, Paul.Audiopath: NAS>JRiver>Audioquest Dragonfly v1.2>Mac1700>Speakers.

Rated 5 out of 5 by from Sound better than they costI put these together a few weeks ago, and they sound great. The build is pretty intuitive. Make sure you do some reading before purchasing these, you'll need to order a few extra things, binding posts, speaker feet, acousta-stuf, etc... I'm happy with the final product, like the title implies, they're a much better speaker than the $120 that they cost. I'm powering them with an AudioSource AMP 100, and using a 12" sealed sub I put together.A few notes:They're small. I think they definitely need a sub to compliment them and take some of the pain off of those poor little drivers. I am, however, using them in a small living room as mains which obviously isn't the recommended near field desktop use they were designed for. That said, they sound really nice with a sub I threw together.They're inefficient. I do wish they had a little more oomph. I really recommend you push them with the full 50 wpc that they're capable of handling, otherwise you might be disappointed with the volume they put out.TIPS: Sand a bunch-- I used a small orbital sander to square up all of the edges, and I'm happy I did. Also, I found wipe on poly to work really well; you'll need to do a good amount of coats, but it makes for a nice finish. Do your research, read up on the crossover design. After you assemble the crossovers, triple check your connections so you don't have to pull these things apart to fix them.Overall, I'm really happy with them. It was a great first project, I learned a bunch putting them together and have the DIY itch now. Despite a few cons, for the price, these speakers absolutely deserve the 5 stars.

I was thinking of getting this kit and incorporating it into an outdoor bar Im building. I was thinking of powering it with the Lepai LP7498e so I would have a blue tooth source for it. How well would that setup work?

Asked by: kram38
These speakers would be a good match for that amplifier. If it is going to be outdoors, make sure the speakers and amplifier are not out in the elements.

can i use one of the silk dome tweeters instead, will it fit?

Asked by: soundbob squarepants
We do not recommend using different tweeters in this design. Not only would cabinet modifications be required, but the crossovers would need to be completely redesigned.
