Soprano MTM Loudspeaker Kit

The Soprano MTM by Jeff Bagby

A small driver, two-way kit using the fine drivers from SB Acoustics.

This kit follows a typical path.  A TM is designed, becomes successful and then the MTM is requested.   This system is every bit as good as its little brother with the added output of 2 bass units.  The woofers are wired in series so it is an amp-friendly, 8-ohm system.

Please note, that this system is priced as a single unit, for those who would like to use it as a single channel or purchase 3 pieces for an LCR.

The full kit includes everything you need except the cabinet:

• 1 x SB26STCN, Neo tweeters
• 2 x SB12NRX25, Mid Woofers
• 2 x Crossover parts, with MDL XPP / NPE caps and specified Inductors
• 2 x Add your choice of Terminals
• 2 x Port tube
• 2 x 18ga twisted-pair Hook up wire
• Internal Damping (not pictured)
• All mounting screws
• Build plans

A Bare Bones kit is also available and includes:

• 1 x SB26TCN Tweeters
• 2 x SB12NRX25 Mid Woofers
• 2 x Crossover parts
• Build Plans

As always, substitutions of terminals, capacitors, etc. are welcome.  If you have a favorite cap brand or like other terminals, we are happy to price the kit accordingly.

Not good at soldering?  choose the “assembled crossover” option and we’ll build and test them for you.
