my D-Box loveseat was a 2 axis seat before I upgraded it to 3 axis.
Unfortunately, I only used it briefly with the 2 actuator/front pivot configuration, before I removed the two actuators/syndrive and sent it to D-Box to have it reprogrammed and upgraded by adding a 2250i.
Motion and vibration was still good in two axis, as far as I remember, but as I was previously using an UMP-200 (now SRP-230) under a Ligne Roset sofa and that was 3 axis, I didn't want to downgrade on the new love seat.
What I learned when moving to the loveseat was that it is advantageous to don't have the feet on solid (=non-moving) ground, which used to be the case with the "old" sofa/UMP-200 combo.
Anyway, I have a quite different challenge. Actually, it's kind of a luxury problem. I am plannung to have a dedicated home theater in my new flat that I have acquired a year and a half ago. I am still in the process of remodelling but one day, there will be the dedicated home theater room on the lower floor.
I do have the 3 axis love seat and that one, I want to keep definitely. I also have an UMP-200 and a SRP-530.
- The UMP-200 is nice as it can be integrated into a seat and the load capacity of 700lbs/328kg is good for a one or two seat configuration. When combinging two seats, however, I expect they have to be in a row. Having them in an angle might make it harder to hide the actuators in the armrests. The distance between the two actuators in a module is fixed (as long as one does not disassemble the modules), which also has to be taken into account when drafting an application. Vertical lift of the actuators is 1 1/2".
- The SRP-530 on the other hand can handle up to 2000 lbs/907 kg, which means that up to 6 people can be put on the motion system. The horizontal actuators are invisible under the platform. One is free to mount whatever seating fits onto the platform, i.e. Home theater seats, even in an angle, standard movie theater seats, maybe even in a two-row configuration. The SRP-530's vertical lift is 3/4".
While the UMP-200 is easier to accomodate, as it can be put wherever a one- or two-seater fits, the SRP-530 has its advantages too.
Well, I will keep contemplating on the advantages of one or the other config and finally make a decision... and the "surplus" will have to go on the European flebay...
