I am looking to buy a good quality sub. As I have no experience with subs, I thought it would be a good idea to have one on home loan before committing to buy. Based on threads in this forum I was keen on trying a BW ASW750. So, this lunchtime, I went to two of the dedicated audio shops in the town (no names) to enquire after the 750. The first shop didnt have the 750 but did have some lower-end BW subs. The second shop did have a 750 in stock. The advice I got from both was very interesting & surprising. The first shop told me that because the lower-end RELs were so good, they were going to cut back on their BW subs. Effectively, I was advised to try a REL the 750 would have to be special order so a home loan was difficult. The second shop enquired as to what I was going to use the sub for (music & movies) and then went on to say that although the 750 was very good for movies, I would be much better going for a REL as this would allow me to use high-level inputs which would provide a much fuller bass for music. Again, effectively, I was steered to the REL range I must admit, based on this forum, I had the impression that the 750 was an excellent sub able to compete with the best at its price point (SVS excepted, possibly). Or, might there be another reason why I was being steered to the RELs .? Was I given good advice? Was the dealer opinion reasonable? My room is 2700 cubic feet and I listen to music at -15 to -13db to reference on my system. Also, does anyone know how good the electronics are in the 750? Would it be a good idea to take the line-out on my stereo pre-amp and feed it into the 750 and then take the line-out from the 750 and feed my power-amp for stereo? Would the quality of the signal be preserved after using the 750 for filtering out the low frequencies? Any thoughts or opinions gratefully received.
