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.

Rated 5 out of 5 by from Well worth the time and effort, amazing tight bassAfter salivating over this kit for at least a half year, I took the plunge and ordered it in January. I really took my time with this DIY kit, partially due to waiting for some new speaker front panels because of the condition of the ones I received and my desire to use a natural wood stain on the Birch. I am including some pictures of my journey along the way. The first set of front panels I received had a "knot patch" on the side of one, and a deep gouge on the edge of the other. If I had planned on paint these a solid color, I may have just kept them. I contacted Parts Express and they quickly sent me replacements along with a self-addressed UPS label so I could send back the original front panels. New ones were PERFECT and came within a week's time. I had already started work on the crossovers, used a thin piece of plywood and drilled holes so I could solder everything underneath. I used a combination of some photos in the review section, Soundfreak's thread in the forum section, and the instructions that came with the set. Used a hot glue gun for all components and zip ties in addition to the glue for the air-core inductors. I connected everything to my amp for testing using alligator clips to ensure it was all wired up properly and it was. For gluing the top, bottom, sides and back, I bought 4 long wood clamps and one ratcheting strap clamp. I glued one with the wood clamps first, let sit for several hours, then transferred the ratcheting strap clamp to that one and glued the second one with the clamps. I cannot stress how important it is to get your edges to line up as best as possible as it will minimize the amount of sanding later. I sanded the partially assembled boxes while I was waiting for the new front panels to arrive. I sanded and sanded and sanded and sanded. Used a palm vibrating sander for the most part, went through a lot of paper as the plywood is extremely strong. I may have gone a tad far through the veneer in some spots, but you can barely tell with the end result. Decided to wire up the binding posts and install crossover into cabinet before gluing on the new front panels so I did not have to work through the woofer hole. I fashioned up two triangular pieces of wood and used silicone to fix the crossovers inside the cabinet at an angle so I made sure I had perfect clearance for the rear of the woofer. This worked rather well since all that was left to do after stain and poly was to solder the woofer and tweeter wires. Regarding the adjustable ports, I found that they would indeed be able to be inserted fully through the back of the box, even though the fit was tight, so I glued them with horribly expandable gorilla glue and then inserted them into the cabinets and screwed them in once the stain and poly was done. I used Minwax natural stain, only one coat with a few touch ups here and there after a quick sand once I glued the fronts on. Used a hand rubbed Minwax poly after this, 3 coats, with a light sand of 220 grit in between coats. Hung them from the basement ceiling with string so nothing would touch the poly while it dried. Final assembly was the most rewarding part! I took care of the ports first as noted above. Next, I test-fit the woofers first and drilled pilot holes for them. Then I pulled wires through woofer and speaker hold, cut tweeter wires a little shorter and soldered everything up tight. I did the tweeter first as that is an extremely tight fit into the hole, mostly went in with hard pressing of my fingers, but I did use a large socket that fit in the right spot to tap them in flush. Before soldering the woofers, I made sure that I had the rubber gasket affixed to the front panel as if you forget this part, you will need to un-solder and re-solder in order to get the gasket in. I tossed a handful of white fill I bought from parts express into the box behind the woofers, that I had pulled apart as noted to create more surface area. Screwed everything up tight with the Pan head screws I ordered here and was finally done! I hooked these up to an older, but adequate Sony receiver, using an Ipod attached to the head phone jack via an RCA cable adapter for the music. Pretty much right away I could tell that the sound quality was such that I'd never heard before. The sound stage remains in between the speakers, almost as if it's coming out of the receiver, no matter where you move your head. What I was most impressed with however was the tightness and accuracy of the bass, in addition of the speaker's ability to produce excellent mid-range frequencies all while these woofers are working up a sweat. These overnight sensations really do turn songs you have heard hundreds of times over into a brand new song just because of all the bass notes and frequencies that were absent on other speakers. I'm in love, and now completely addicted. Thanks Parts Express!

Rated 5 out of 5 by from Fun ProjectReally enjoyed the process of building these and enjoying the results even more. This was my first time building speakers and can say that with careful planning and patience, anyone could build these. Also, being my first time, cabinets could have turned out with a better finish, but will easily be able to make the needed adjustments next time. And yes, they are so good that I plan to build more.

Rated 5 out of 5 by from great speakersThey punch much higher than their price or size class. Very impressive. Watch the video, it makes assembly much easier.My only gripe is: Include 16 of the wood screws! It doesn't make sense to sell them separately in a pack of 100 when it would cost less than a dollar to include the 16 that are needed.

Rated 5 out of 5 by from Amazing speakers. Rocking my office!These are the second set of speakers built from parts express. I built the Tritrix MTM as well. These were much easier to build. I finished these with a wipe on indigo stain and am not completely happy with the finish results, but that is my fault. They sound really awesome. I just hooked these up to the Dayton Audio 150 watt amp in my office and am listening to Miles Davis. I think these speakers really do well with jazz. They just nail that warmth and mid tones.

Rated 5 out of 5 by from Better than expectedI really like the Overnight Sensations as did others. Here are some things I want to share with you:• I had somebody else do the crossovers as my hands aren't steady.• The sound did not disappoint on an inexpensive SMSL Q5 amp. The speakers responded well to audiophile equipment especially when playing female vocalists such as Holly Cole.• During assembly of the cabinet, I left the back panels off until I had glued the crossovers inside. Good idea for putting the crossovers in but a bad idea for matching up the panels to the rest of the glue dried cabinet. It made for some ill fitting cabinets and extra sanding to fix.

Are these loud enough for a large living room? Hows the bass on these? 

Asked by: Cowdy
Everyone has a different idea of loud so that is somewhat difficult to answer accurately. I would consider them loud enough personally but since they do use small drivers you may need a subwoofer to fill in the bass. They do well for their size, but with them being small speakers the bass could be improved, especially in a large room.

Are there any ribbon tweeters that are compatible with this system? Specifically circular and similar in size - for future upgrades and such. Also what damping material would be recommended with these, or any at all? Just fyi, I am a newby.

Asked by: Slightly Nordic Andrew
Changing the tweeter would also require redesigning the crossover and it would really be a completely different speaker. We do not recommend substituting any drivers in a kit for this reason. I use acousta stuf personally but you can use either that or acoustic foam in this type of speaker. Either way is fine.

What else do I need besides the kit?  What kind of amp should I buy?

Asked by: corey6378
You would need some sort of speaker connector, speaker wire and an amplifier capable of driving 8 ohms loads. Just about any of the parts in each category would work for this setup

Good Afternoon, Do you have an estimated time when the Overnight Sensation MT kit will be available again?

No soundproofing or blanketing inside to dampen the cabinet ?

Asked by: Oddiofile
None is included in the kit, but you can still add fill if you would like. Lightly stuffing the cabinets would be a good place to start but you can add or take away amounts until you get the sound you like.
