Product Details

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 4.7719 out of 5 by 57.
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.

Rated 5 out of 5 by from Great sound, great look!I am so glad I found that kit. As a beginner in the speaker design it truly helped to have a design already made. I can wait to do it by myself now! I added damping inside and am using an amp to give enough power to the speakers.Also the tweeter is connected with a different polarity than the woofer.Don't forget to buy screws if you haven't done it already because they are not included.

Rated 4 out of 5 by from Ver goog set of speakersI bought all the pieces separately and build my own cabinets, when I first listen to them I was really impressed, deep bass and clarity, I hear the voices between the speakers, and one can locate the musical instruments in some songs, the scenary is there, definitely for the quality sound these provide, you would have to spend much more money, buy them, you got nothing to lose

Overnight Sensations MT Speaker Kit Pair

I saw the overnight sensations and I am really interested. My questions is do you have something similar but bigger. I was thinking maybe 20hx 12wx 8d. I was also thinking about an 8" speaker. 

Asked by: DanNyg
We do not have anything that uses an 8" woofer in kit form. We have many different kits available which you can see below.http://www.parts-express.com/cat/speaker-kits/286?N=19888+4294967118&Ne=10166&No=16&Nrpp=16&Nrs=collection%28%29%2Frecord%5Bendeca%3Amatches%28.%2C%22P_PortalID%22%2C%221%22%29+and+endeca%3Amatches%28.%2C%22P_Searchable%22%2C%221%22%29%5D&PortalID=1

RE: Mono speaker project. Hi again, Just a thought... The 2x50w board amp suggested is a stereo amp. Wouldn't this be a problem if I am to make one single mono speaker? I read in a thread here that if I bridge the two channels I might get a distortion a

Asked by: Newbiz

I'm thinking about bying the parts list without the cabinet just to make one mono active speaker. What amp board is suitable for this?

Asked by: Newbiz
Something like the amp below would work well for that application.http://www.parts-express.com/2x50w-tda7492-class-d-amplifier-board--320-301

Hello, I'm wondering how the output would be like? I don't know much about sound hardware but is it the analog green wire that you can put into your computer or is it the ones that the surround sound systems use that you have to wrap around the back?

Asked by: seppy50
These are passive speakers so they will require a separate amplifier in order to work. A surround receiver will work for this, as well as many small table top amplifiers for applications such as use with a computer. These will have relatively limited output and won't shake the house, but for close range applications they will work well.

I'm a newbie building this speaker kit for the first time. I'm looking at the cross over schematic and see that the negative input is going to the positive terminal of the Dayton treble. Is that a typo, or is that by design? If by design, why?

Asked by: SteveInRingwood
This is by design. The type of crossover used causes an acoustic shift in phase which is corrected by electrically wiring the tweeter in reverse polarity.

I will be putting these in an entertainment center with fairly large cabinet style openings with closed backs. Would it be wise to relocate the bass port to the front of this speaker so the low frequencies aren't just bouncing around behind the speaker?

Asked by: Bassman969
Yes that would be advisable in this type of application. Be sure to seal up the opening on the back for the best results.
