SpeakerPower recently released a new line of rack mount and plate amps that are geared toward the DIY crowd. While their amps used to have strictly SpeakOn, PowerCon, and XLR with no user-controllable EQ, crossovers, or phase control now have binding posts, NEMA-15 power cords, RCA inputs, and all the aforementioned signal controls.
Also making things more appealing is a recent price drop across the board!
I know Brian frequents most of the forums out there, so I’m sure any questions here will be answered.
My first experience with SpeakerPower amps was when Jeff Permanian (JTR Speakers) brought his highly acclaimed Orbit Shifter LFU to my first AVS GTG in 2013. I couldn’t believe a plate amp (SP1-4000) could bring a single enclosure to such immense SPL levels (tested by data-bass.com to exceed 130db).
These amps are also used by Seaton Sound, Danley Sound Labs, Power Sound Audio, and Deep Sea Sound to name a few.
I purchased my first SpeakerPower amp (rack mount SP2-12000) at the end of 2014 to drive a pair of Othorn tapped horn subwoofers (designed by Josh Ricci of data-bass.com) loaded with B&C 21-IPAL drivers. These drivers have an unusually low Re of 0.7ohm, and even though the impedance drops to ~1.1ohm while loaded in an Othorn, the SP2-12000 has effortlessly drove these subs all while remaining cold to the touch. In the last ~1.5 years I’ve only seen the fans actually turn on two or three times. I’ve measured SPL levels just north of 139db at the seats in my HT room with just these two subs and a single SpeakerPower amp!
I recently purchased another SP2-12000 to power my latest project of (8) sealed 21” drivers and I’m thrilled with the results. I encourage anyone else using these amplifiers to post their experiences here!
