Overnight Sensation MTM Loudspeaker Kit

Product Description

Overnight Sensation Speaker Kit – MTM Version by Paul Carmody

Looking for a low-cost home theater kit with big sound?  Paul Carmody has done it again. Now there is an MTM version of the popular “Overnight Sensation”.  Adding the second woofer increases efficiency (about 85dB)  and power handling.  I encourage you to make this build.  You will be pleased with the results.

Please note that this is a nominal 4-ohm system.  Be sure your amplifier can hand this low impedance.

Please note we have priced these kits as “Each” to allow the purchase of 1 (Center) or 3 for LCR combinations.  2 channel lovers can simply buy 2.

Why The Tweeter Choice? 

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

How Do you choose?  If you have an existing Overnight Sensation with the Dayton tweeter, you should choose it to match.   The downside to this tweeter is that there are no screw holes in the mounting flange – the tweeter needs to be glued in place making 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.

How do they Sound? 

The sound quality of the MTM version of the Overnight Sensations is the same as the original TM.  The sound is big, and they sort of pick up where the TM version leaves off.  Where the TM version does its best work in a small room, the MTM version can easily rock the walls in such a room… and might be better suited to a medium-sized room.  They work as desktop speakers and will have a nice, immersive soundstage.  Please be careful with your hearing–and be respectful of those whose desk is near yours.  These things pack a bit of a party.
