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. Binding posts and speaker wire are not included, but recommendations are featured in the Related Products section on the right.

Rated 5 out of 5 by from Fun Project - Well worth the journeyIt took many months to see this to the end but it's a fun project that let's you learn a lot about many different aspects of the craft. Well worth the journey.I learned that I can't even put a pre-cut box together straight. That I can't solder worth a darn, and my sanding and finishing skills are adequate at best. BUT I HAD FUN THE WHOLE TIME.I also made the awesome choice of asking my wife to customize my speakers and after discussions we decided on the designs you see. The are a variant of Pakistani Henna (I though it looked cool) and she used a hobby lobby wood burning tool to burn the designs for me. They are the envy of my office and it's a great conversation starter. I get a chance to brag about my awesome wife all the time now :)As for the sound, I'm not really an audiophile but they do good enough for my office with a lepai amp.Look for threads in the forum for information on how to build these as there is a ton of information there.Hope you enjoy.

Rated 5 out of 5 by from Office never sounded betterOne of the best beginner DIY projects, hands down. A ton of fun with the assembly, even more now with them entertaining me at the office. These are a must-have, but be warned: this kit will be the "gateway" into other DIY projects.

Rated 3 out of 5 by from no schematicsThey sent me all of the parts but no schematic for the crossover. What goes in a series and what goes in parallel? Also the ports are variable and I don't know how long to make them.

Rated 5 out of 5 by from Exceeded expectationsWell, it took me a year to get around to it but they're finally done, except for the finish. Bass response and overall sound quality far exceed what I expected from the price and they sound much larger than their actual size. Construction was fairly straightforward although I wish I had consulted the video before assembling the boxes with the backs glued in place and the faces going in last. Plywood had a stain and a couple of dings and voids, but not a big deal at this price. They're for a desk in a room no one sees.

Rated 5 out of 5 by from Excellent sound, fun build.I bought these speakers for my workshop, but they really belong in a listening room. The range is incredible given the size of the cabs and drivers.

Rated 5 out of 5 by from NiceThis was my first speaker project.  The hints in the reviews and forums were very helpful.  I'm very happy with how they turned out, the sound is much more than I expected.

tweeter sound?

A big duh question here from a total newb. I am putting my crossovers together and wanted to test before installing. Somewhere along in internet research on this crossover build it was suggested to test with a 1.5V battery if one was worried about damage. So, that is what I did. But, I don't hear a pop or any sound out of the tweeters.So, I wire them up to a small amp and all I seem to hear is very high end sounds. Nothing "musical" if you know what I mean. If I only have tweeters connected I don't hear music but just some sounds.Woofers sound just fine. Plus, the volume from the tweeters is way down. Same on both set ups. Is this what to be expected or have I messed up my crossover wiring?I don't want to put them in the cabinets and such until I know they are right on.Thanks in advance.
Asked by: bigpix
You generally won't hear a pop from a tweeter with this test. 1.5 volts DC directly into many tweeters can damage voice coils. The best way to test a tweeter is simply to hook it up in the design and verify it works unless you have test equipment and a proper high pass filter on the tweeter itself. If you have the tweeters wired directly to an amplifier with no protection from low frequencies they are very suseptible to damage and they will sound much quieter than a woofer at the same volume level. 80% of the sound you hear comes from the woofer/midrange, the rest is harmonics and sibilance from the tweeter. I recommend getting the whole crossover together as the schematic shows and see how it sounds. Listening to tweeters alone will most definitely raise question if you are not too familiar with speaker design.

Do these sound good in different listener spots in the same room?

This looks ideal for my needs, which are to get decent sound into a 15 x 18' living room and adjacent 14 x 12 dining area. One thing though that concerns me is the description of the OSs as "near field monitors", which to me implies speakers meant to be listened to from very close, and which often have a tiny sweet spot. For example, I own a pair of Samson Media One 4a monitors, which sound pretty good when I am equidistant from them, but moving even a foot or two to one side sharply degrades the sound and soundstage.So, are the Overnight Sensations adequate for music listening in a room where I'd be sitting in various places? Thanks for any advice.
Asked by: bookmatch
That's a complex question. If you are designing an audiophile system - you'll carefully place your speakers in the perfect spot in the room - looks and furniture layout be damned - and then place your favorite chair in the perfect position with no concern for family or friends. At the other end - when you go to a public place - look a the ceiling - the speakers are almost placed like sprinklers to evenly distribute audio like watering a lawn. So if you want to have background music all around your room - you need 4 in ceilings in the living, and 2 in the dining. Or you could put a 5.1 surround in the living room with your TV and the spill over into the dining would be fine. But - will a 4" 2-way sound the same everywhere in that environment - no. It's not possible.

Tweeter polarity

In the crossover diagram it shows the tweeter "-" connection on the top. Is this correct, or is it mis-labelled and it should be "+"?
Asked by: Delongacre
Yes the tweeter is wired in reverse polarity, so "+" goes to "-" and "-" goes to "+".

Pair these with low power tube amp?

Due to the low sensitivity of the Overnight Sensations, could one still power these with an integrated tube amp like the Miniwatt N3 which is only rated at 3.5 watts per channel?
Asked by: Marksas
Big amp or not, these speakers won't rock the walls... They are designed to sound really good within a reasonable volume level. And with a tube amp - and the high current it has which transistor amps rarely have - it will make these sing like beautiful music. You will hear a 3D sound stage and air unlike you can imagine.

wondering what " nearly" all items needed means?

does it mean the finish on the wood, the grilles, ??? what or is there hardware needed to finish them??? I'm so corn fused..LOL
Asked by: step
You'll need to provide your own shop materials, such as glue and sound deadening material.Also, according to the product details, "Binding posts and speaker wire are not included, but recommendations are featured in the Related Products section ..."

Relocating the port hole.

Is it possible, without significantly changing the speaker design, to move the port from the back to one of the sides (or the bottom)? I understand I would have to plug the hole on the back and make a new hole where I needed it.
Asked by: Doug4.7
In many designs the placement of the port does have an impact on sound and in some it simply make a small box exhibit qualities of a larger volume box. If you choose to relocate the port to the bottom and they are sitting on the port then you will impede the velocity of the flow and significantly decrease performance.If is necessary to move it, then sides would be best but some decline may be experienced.
