Hello, I'm looking for a new pair of speakers to match a similar in price AV receiver. Speaker list: Dynaudio DM 2/6 (Neutral), Monitor Audio Silver RX1 (Warm), B&W 685 (Energetic) and the KEF Q300 (Clinical). What speakers do you recommend for £400? Hope you don't mind the questions: Does the sound of the MA RX2 justify the price? Since the driver is larger, the bass response will be better than the others. However, will it produce a finer level of clarity? Does the smaller RX1 driver result in less sound quality than the others? Can the DM 2/6 compete with the others? It has the smallest driver. Distinctions in technology – The B&W to KEF's contain flow ports while the MA includes a rear port and in tweeter terms, there's a new Nautilus tube (B&W) plus a Uni-Q, C-CAM (KEF) and a traditional Gold dome tweeter from MA. All of them are the same size. I see that with a rear port the speaker will have to be further away from the wall. How do these technologies translate to sound? Thanks for your replies in advance.
