When considering modern receivers, you should get one which includes room equalization software. Room EQ compensates for limitations in speakers and room acoustics.
In the mid-priced range, the versions of equalization software provided by Yamaha and Pioneer do not EQ the subwoofer channel. Except for their introductory (low end) models, Onkyo, Denon, Marantz and NAD all provide versions of Audyssey which include subwoofer equalization. You'll have to evaluate their other features to find one which fits your usage best. You should be able to find one that's appropriate for about $500 or less. Often refurbished units can be very cost effective.
