I would appreciate feedback from anyone familar with both models. Is there a significant difference? Thank You.

Kclone I can only speak for the models I owned which were the 1sc, response 1.5 and response 2.5. I had several amps with them tubes and solid state and always found them very enjoyable. Perhaps I should clarify my statement about the Spendors, this again is based on the Spendors I have listened to, I have not heard every model in either line so perhaps take my opinion with a grain of salt. All I can say for sure is that Proac and Spendor make very musical speakers.
Interesting revival of a thread from 2010. I have owned quite a few Proac speakers including Tablettes, Response 2, Response 2.5 and now Response D40r.

All have been fairly easy to drive with great natural sound. I would not call the Proac sound lean or bright.

I have used various tube and solid state amps. 
Actually, the Proac 1SC has a 0.75 inch tweeter, while the DB1 has a 1.0 inch 
tweeter. Both speakers are equipped with 5.0 inch main drivers. I own the 1SC's,
the Response 2's, Response 2S's and the Response D2's. I like the 1SC's best.
Hi, given your experiences with ProAc monitors, which model would be a logical choice if I were to replace my Response D15's due to moving to a smaller room. I'd like to keep the same basic sound of the D15's. Thanks for any opinions. YBA amplification.
