I've had two Sumo Samson subs and the Delilah electronic crossover for some time now, but the Samson's were loaded with JBL E140 15" woofers instead of the proper JBL 2235H woofers. I bought a very nice pair of 2235H's from my best friend in New York and received them yesterday 
.
For those unfamiliar with Sumo products, they are very high quality pieces. The Delilah crossover is small, but weighs quite a bit for it's size. It has machined aluminum knobs, with a silky smooth feel. The Sumo Samson sub's are basically a JBL B380 clone. They have 2"x4" internal bracing and thick MDF panels.
My system consists of a pair of JBL L220 Oracle's with the LE5-9 cone midrange replaced by a JBL 800hz 2312 conical horn and a JBL 2421 compression driver. They are mounted behind the L94 lens. I have a pair of JBL L222 Disco's with rare 800hz McCauley elliptical mouth horns and JBL LE85 compression drivers in place of the stock LE5-9 cone midrange.
Other upgrades include JBL LE14H-1 woofers in place of the stock LE14a's in the L220's and LE14H woofers in the L222's. These two pairs are triamped via JBL DSC260 Digital System Controller. Preamp is a vintage Yamaha C-70, LF power is a Yamaha MX1000u, MF is handled by a nice EL34 based VTL Stereo 45, and the HF is powered by a 4ch Yamaha M35. My main source is a Denon DCD-1560 20bit CD player. Augmenting the midrange is a pair of super-rare McCauley 800hz large format elliptical mouth horns/slant plate lens combo with JBL 2441 compression drivers. Crossover points are 800hz and 8khz, with a 18db per octave Butterworth HP rumble filter set at 19.9hz
The addition of the twin Sumo Samson's/Delilah is a bit of overkill, but I'm sure there are many of you that know the feeling of "if you can have it, why not?" My listening room is fairly large and has very high vaulted ceilings. With the side by side pairs and equipment stand, there is only enough room to lay the Samsons on their sides, with the ports firing upwards. I power the Sumos with a Yamaha M80 250wpc SS. This amp has almost 3db of clean dynamic headroom capability.
The Yamaha C-70 preamp has an extra pair of outputs, which are phase inverted to allow for bridging amplifiers that do not have a built in bridging feature/dedicated bridged input. I use 24db per octave L-R slopes on the DSC260, so I chose a 12db slope via the Delilah's front panel. I cross the Sumo's @ 50hz for now. I tried 63hz, but the L220/L222 pairs have such awesome LF output, I really only need just the bottom octave and a half, if at all. The woofers are wired reversed phase to compensate for the C-70's inverted phase output pair being used.
I've got to tell you, those 2235H woofers are wonderful LF transducers!! Effortless, DEEP bass. Nice, tight and musical. I have an Energy MicroStar 12.1, 1500 watt beast in my HT set up. These Sumos have much better SQ for music, than that Energy ever had. I played The Eagles Hell Freezes Over disc. WOW! At the beginning of Hotel California, there is some really nice percussion and bass drum kicks. The Sumos resolved them right on the money! At least the harmonics below 50hz. No boom, no port huff, just big powerful, realistic drum/tom-tom strikes. I'm very pleased with them. With two of them, the small amount of power it takes to get nice, loud SPL's is suprising. I like that. I've spent 30 plus years seaching for my own personal idea of audio nirvana, it feels right, at this moment. Here are some pictures. I have to re-think my gear rack. For the time being, it's going to have to kinda just stay where it will fit. Thanks for letting me share my system with you all, regards, Steve G.
