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 Crossovers FinishedNo one will ever see these but I'll know what a good job I did!

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.

Rated 5 out of 5 by from Great Speakers!I finished these two weeks ago and have been enjoying them in my bedroom system every night. This was my first kit and I am quite pleased. The speakers have such a clear musical quality to them and sound well-balanced across the spectrum. They have a nice soundstage and instruments can be easily identified in the classical music I usually play.I picked up helpful pointers from several other reviews and found the PE staff very helpful when I needed extra help.The finishing took awhile, partly due to staining and varnishing in the Houston heat and humidity. I used several coats of poly to get a deeper finish, with light sanding between coats. I bought my first wood clamps(4) and find them a must to get a really good solid assembly. The written instructions and PE video were pretty easy to follow. I am thinking whether to add grills but they look pretty good now.I see why others have been pleased with these. They offer top musical pleasure and a sense of pride in building them.

Rated 5 out of 5 by from Perfect bedroom speakers!I recently purchased this kit as a gift for my teenager to listen to vinyl on in her bedroom. Only issue I had was the baffles seemed off a little bit, like 1/16th no more than that much better than I probably would've done!. That tweeter is a tight fit! Crossover wasn't too bad I did quadruple check it before soldering.Otherwise a excellent project the cabinet panels fit together very well. I've only used MDF on my other projects working with the birch ply gave me a reason to try out staining. I went with minwax water based stain "Deep Ocean" & water based polycrylic with duplicolor truck bed liner on the baffles. Turned out pretty good for a first time. The sound quality on these is pretty remarkable given their size. Hats off to Paul Carmody for sharing his endeavors & to PE for providing the kit!

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

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!

Overnight Sensations MT Speaker Kit Pair

Considering these kits for a senior project for our 11 graduates. Anyone used/modified these to make portable amplified single speakers(to plug a phone into)?  One kit / two girls. I'd need a mono amp board and lipo pack / student. Seem doable? Thoughts?

Asked by: Scott_PdP

Is there a way to test the crossovers?

Asked by: Pablo88

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.

I know that the ratio of port length to the port crossectional area is a constant.So ,for the port can I use a pvc pipe that has 28 mm inner dia instead of 32 mm as requested by design without any problem? (Air turbulance noise, distortion etc) thanks

Asked by: portisheader
Yes that diameter will work fine but the length will need to be shortened to 113mm to maintain the same tuning frequency.

What does Mike apply to the crossover before gluing them to the cabinet with the PVA glue? Sounds like water or something. Around 6 minute mark into the video. Thanks

Asked by: Sergei971
Yes this is just water as the video explains. Gorilla Glue requires water to be applied to both surfaces in order for it to work properly.
