Hi mike, on my 1250 i like the dsse10's , i dont have the dss9's. Now on rhe other hand on my 1980 i like the 150's . I have heard the hpm900's but not the 1100's. If your looking for a good speaker i would pick up a set of hpm 100's or a set of jbl l100's. Sence both speakers were designed by the same person thay are very compareable. To my ears anyway. You may want a different sound . Good luck on your search. James
