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.

Rated 5 out of 5 by from Great project!I bought this as a first time speaker builder and was a little intimidated by it at first. But the instructions were thorough and the video helped a bunch. The final product is excellent and I really couldn't be happier
Date published: 2015-06-28
Rated 5 out of 5 by from great valueI assembled these a few months ago and love them more every time I listened to them. Assembly was fairly easy and straightforward, though finishing them probably took the most amount of time. You end up with quite a bit of high sections on the ends that need to be sanded down considerably to get the edges nice and smooth. I choose to go with a sanding sealer and satin clear coat. In hindsight, I should have gone with a thicker gloss finish, but not a big deal.I use them for desktop computer listening through a line out signal from my imac to a sherbourn PA2-50 amplifier. They're sitting on a pair of small isoacoustics stands with the tweeter perfectly at ear level. I could not be more happy with the sound. Music jumps out from my screen. Center is smack dab in the middle of the screen with great stage width & depth. Instruments are distinctly placed and every nuance is clearly heard. They can be a little mid-bassy, but I think that's more from the lack of rear wall treatment.I first listened to them in my living room sitting on tower speakers powered by my HT receiver and they are definitely capable of medium size room duty. They put a deceivingly huge sound with very strong bass.The kit arrived without a pair of the resistors. I emailed PE and they immediately sent me the parts. Great customer service!All in all a very fun project. I can't wait to get started on larger monitors for my living room!

Rated 5 out of 5 by from Great speaker kits for the money!I can't be more pleased after finishing this kit. All materials were made well and great quality and would recommend this as a great gift for the DIY person.

Rated 4 out of 5 by from great sound, built my own cabs and crossover boardThese are great sounding speakers, and as others have commented, they need a good amp to power them since the sensitivity is low. It's better to have extra power to avoid clipping the amp, and also avoid damaging the drivers with square wave signals from a clipped amplifier.I encountered some (minor) problems with the ONS cabinets and how some of the components are mounted. Even though the Birch plywood cabinets were supplied with the kit, I decided to make my own cabinets from ½” MDF using spline joints. I have made dozens of cabinets this way with excellent results. They almost assemble themselves!I also developed a good technique for making the crossover boards which really should be included to make this kit complete. There are many photos and illustrations on line of how to make the crossover board assemblies. I made mine using heavy (1/8” thick) perf board available from Watts Tube Audio. This material has 1/8” holes on 3/8” centers and is used primarily for guitar amp circuit boards which use point to point wiring. Watts also sells the eyelets which fit into the holes and a small staking tool. Once you figure out where you want the crossover components to go on the board, the eyelets can be installed at all the tie point locations for soldering. Where necessary, the extra lead lengths for the components can be routed on the back of the board to form jumpers, for connecting everything together. Additional holes already in the perf board can be used for the mounting screws to fasten the board inside the cabinet. This arrangement worked very well.If you send me an email I will send you all the documentation and photos which are too much to list here on the review.Here are a few pics of my project. I will definitely make more of these speakers.

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...

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.
