Overnight Sensations TMM Speaker Kit

Product Description

Overnight Sensation 2.5 Speaker Kit – TMM Version  by Paul Carmody

Back when Paul designed the Overnight Sensation MTM, he knew some folks were going to want to make towers out of them–and there are plenty of excellent examples out there. However, his mind would always play around with the cabinet shape, wondering what else was possible. For some reason TMM towers are almost always more pleasing to his eyes than MTM towers; maybe they create less visual impact in the room, maybe they look less like they might tip over, maybe he could just sense the Spouse Approval Factor.

Why The Tweeter Choice?

Paul did the original TM design with the Dayton Audio tweeter. When that tweeter was out of stock for an extended period, Paul did a quick design using a similar Hi-Vi tweeter.

Which tweeter do you pick?  If you have an existing Overnight Sensation build with the Dayton tweeter, pick the Dayton to match.   The downside to this tweeter is that there are no screw holes in the mounting flange. You will need to glue it in place.  That makes it hard to remove.

The Hi-Vi tweeter has a 4 hole mounting flange and is less expensive.  I think Paul said he actually preferred this tweeter but they are really a toss-up.

There is a cabinet design for both 1/2″ material and 3/4″ material.  The 3/4″ one is 38″ High, 6″ wide and 9.5″ Deep.

Paul did not specify any particular “Brands” of crossover parts, so we provide what we think are the best value.  We are happy to substitute any brand you prefer at the price difference. Please give us a call or email before ordering.

How do they Sound?

Everyone who’s heard the original Overnight Sensations always thought to themselves, “Well, the bass is pretty good, especially for a speaker this small.”  So what happens when that same speaker isn’t quite so small anymore?  What kind of bass do you think you could get?  Yeah, the bass is pretty sweet on this.  The F3 is around 39 Hz, but I voiced it with a just a hint of the extra boom in the low bass because it kind of kept with the same sound as the rest of the Overnight Sensations family.  You will be pleasantly surprised when a synth bass line comes in and you feel it.  Personally, “I wouldn’t feel the need to use a sub with these unless I was watching a lot of action movies.”  The mids and treble are right in-line with the rest of the Overnight Sensation family.

Paul says, “I only regret not putting this design together sooner, because over the years I’ve seen people wish to build something from the Overnight Sensation series, but wanted something floor standing, or with just some more bass to fill a medium-sized room.  For everyday listening in a small space on a budget, I think this thing is a home run.”

If a slim tower DIY speaker kit has been our your wish list, I encourage you to build this one.  It is almost certain you will impress your friends and relatives.
