Stereo Integrity TM8 - Midbass SetWelcome to the TM8 loudspeaker. A completely new low distortion driver designed in Finite Element Analysis here in North Carolina. Our TM8 uses our custom tooled cast aluminum basket with an integrated rain shield and a very shallow mounting depth of only 2. 3. Twin shorting rings lower and linearize inductance for an Xmax: Le ratio only found in significantly higher priced loudspeakers. With good sensitivity and 7 mm of Xmax the TM8 effortlessly
Welcome to the TM8 loudspeaker. A completely new low distortion driver designed in Finite Element Analysis here in North Carolina. Our TM8 uses our custom tooled cast aluminum basket with an integrated rain shield and a very shallow mounting depth of only 2.3″. Twin shorting rings lower and linearize inductance for an Xmax:Le ratio only found in significantly higher priced loudspeakers. With good sensitivity and 7 mm of Xmax the TM8 effortlessly provides pant-leg-slapping midbass. Power handling and linear inductance characteristics are accomplished by its 50 mm voice coil with solid copper windings mated to the pure aluminum cone body. The pure aluminum cone body was carefully designed with the best strength-to-weight ratio to allow for proper frequency extension and strength for midbass / deep bass extension. Perhaps most importantly is the combination of the copper voice coil, CZA former, and aluminum cone also offer tremendous thermal advantages as they all work in tandem to extract and disperse heat from the voice coil which increases thermal power handling.
We designed our TM8 with a higher-than-average Qts. The main install location for our TM8’s is in a vehicle door. A vehicle door is a very lossy enclosure that closely mimics an Infinite Baffle alignment. To achieve the most performance from an Infinite Baffle alignment you want your Qts to be close to a 0.707 Qtc alignment of a sealed enclosure, which is why our TM8’s Qts is in the 0.8 region. With our Qts close to a 0.7 it yields the best combination of low-frequency extension and natural output capability. Our TM8 is for those of you who want a plethora of midbass capability without sacrificing mounting depth and/or price.
Our TM8’s primary purpose is for use as a midbass driver. Its on-axis frequency response does extend up to 4,500 Hz so it can be mated to our M3 Carbon midrange and M25 mkII tweeter for a 3-way setup or mated up directly to our M25 mkII tweeter for a 2-way setup.
In-vehicle frequency range is 27 Hz to 7,000 Hz. We recommend a high-pass crossover frequency of 40 Hz or higher. Recommended high-pass crossover slope is equal to, or greater than, 24 dB/octave. Recommended crossover frequency for a 2-way setup is 3,000 Hz. Klippel measurements can be viewed by clicking the images above.
