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 Small Bookshelf Speakers Pack a Big PunchI bought these because I needed small bookshelf speakers to fit in a custom cabinet. These were the perfect size plus they got great reviews so I went for it. Let me tell you right now, these speakers rock! I couldn't be happier! It took me about 3 days from start to finish. I will admit, I've never built speakers before and never soldered so I was a little intimidated by building the crossover.For others that have no experience, have no fear, just follow the video and the wiring diagram. Once you get the general layout from the video, go to the diagram, it's much easier. Then think of each "dot" on the diagram as a metal post you want to tie the connections to. Make sure your soldering iron is clean, or else your solder will not "wet" properly. And the most important thing you can do is to TEST your speakers before you glue the back on. I also decided to put Poly-Fil stuffing into the box because it will keep the wires snug and seems to enhances the bass (I have no data to back this up other than my ears).One of the other great things about these speakers is you can finish them however you want: stain, paint, glaze, antiqued, etc. I've done my share of woodworking in the past so the cabinet assembly and finishing was very straightforward.

Rated 5 out of 5 by from Fun Project - Great SoundGot this kit for a desktop system, after reading the reviews, and am very happy! Had a great time putting the boxes together, soldered up the x-over, a little stain, a handful of acoustic fill, and bam. Quality components + great design = excellent sound.

Rated 5 out of 5 by from UPDATE: Can't wipe the smile off my face!!Seriously, if you are reading these reviews and mulling over- just stop and buy the kit and whatever else you need to build them. You can go crazy with all the reviews and audiophile malarky, but these speakers simple sing to you. Music is fun to listen to and believe it or not they sound great paired with that cheap little Lepai 2020 amp.Just do it! Plus you will have a great time building them!

Rated 5 out of 5 by from I want another pair!I bought these to use with my workbench system. I'm impressed with how well they sound for such a small speaker! I now want to build another pair in a MTM configuration for the bedroom. You can't go wrong with these, pretty easy and fun to build.

Rated 5 out of 5 by from Wow! I am blown away by the sound! Really FUN too!This was my first build after getting great advice from the forums. First of all, it arrived in less than 48 hours for free-SWEET!So the build was pretty straight forward. Box requires some sanding to really clean it up, but it goes together very easily.Not wanting to spend $$$ on clamps, I used masking tape to help me hold it together while I glued and then used cargo straps, with foam pipe insulation cut up to pad the corners when cinched up. Worked like a charm and cost me 1.87 for the foam :)The crossover seemed daunting at first, but after pausing the above video at just the right place a few times and finding some photo examples by searching, I was able to get it together fairly easily, but I have to say it is the sloppiest thing I've ever done.I've only ever built models and a few handyman jobs, but never soldered.anyway, I put the whole thing together and patiently waited for the rear panel glue to dry overnight...........WOW!!! I hook these bad boys up and am immediately in shock at how great they sound.And the BASS- the PERFECT speaker for my 10x11 room. The floor shaking bass is unbelievable. Everything sounds crisp, life-like and very authentic on live recordings. And to top it all off, I am proud of how nice they came out and had an absolute blast out in my garage over course of a few days.Do it NOW- spend a few bucks for soldering iron, glue, etc and you will have an AMAZING set of speakers and sense of accomplishment. I've been listening for HOURS and they keep getting better.

Overnight Sensations MT Speaker Kit Pair

Did you use any sound dampening foam in your build? Is it not recommended in a knock down cabinet?

Asked by: kjacksonaudio
Sound damping is optional in any build, we just do not include it in this kit. Lining the walls with foam or stuffing the cabs with poly fill is recommended but not required.
Answered by: MattP

Is there a maximum power recommended for the speaker set? I'm contemplating what receiver to buy for my set-up and don't want to damage the speakers.

Asked by: Same
The maximum power handling for these speakers is 50 watts each.

Is there a missing '500' Hz between the high end of the midbass 3000 hz and the low end of the tweeter 3500 hz?

Asked by: pshop
Paul designed this speaker based on actual in box measurements and came to a final crossover point of about 4.1kHz. There is no gap in the lower midrange in this design.

Date published: 2014-06-19

I recently got these and have just assembled the crossover to what I think is correct (after looking at similar online pictures). However upon testing, the sound is limited, but it seems that the low/high pass filters work. Has anyone had this problem?

Asked by: engsbro
I would recommend contacting our tech support for help with this. It may be best to email detailed pictures of the crossovers to tech@parts-express.com.

So if I buy two pair, can I use them as front left and right, and rear left and right, as part of a full 5.1 surround system? I would still need a center channel and woofer, but would this be a good starting point?

Asked by: dkline201
This speaker would be an excellent start to a home theater system
Answered by: Chrisf

What is the approx. frequency at which this crossover operaters? I'd like more info generally about how to select tweeters + crossover frequency. Thanks

Asked by: SpinCycle
The crossover point in this design is roughly 4,200 Hz. I would suggest a book we sell called Speaker Building 201 which you can see below.http://www.parts-express.com/speaker-building-201-book--500-044
