I am new to the forum and wanted to say hi. I am slos about to pull the plug for 2 subs for my music only system. I have 2 ACI Jags with LFM modules. The only experience I have with subs are form ACI (They are out of business) and Velodyne. How would Rythmil measure up against Velodyne in terms of difference in sound? I would be considering the Optimum series (probably the 12) from Velodyne
