No .. there's no concensus.
If your listening room is small a separate subwoofer can give more flexibility in placing the main speakers for imaging and the sub for optimum bass loading.
Either way good deep bass is quite expensive. If you get a separate sub then these cost $1000 up. If you want deep bass from the main speakers you'll need a much more powerful amplifier and physically large speakers.
