Bass Issues

I have an Arcam SA-20 integrated amp, B&W CM5 speakers and an SVS SB1000 sub. I previously had 20 yr. old B&W DM602 speakers. I sold them. The 602's 7" drivers were great with bass but lacked in other areas. The CM's (6.5" driver) are much better in midrange and treble but I'm having trouble getting the bass dialed in. They can get a little boomy and lack a clean drum punch like the 602's had.

I've got them 26" from the rear wall and am using the outer foam plugs in the ports. You can plug the entire port or take out the middle part and just use the sleeve. I've spent days inching the stands around, toed in, not toed in. I was using an AVR as a preamp with the 602's so I had crossover capability. With the Arcam I don't. I'm a little lost without that feature. The CM's sound best when I can cross them over at 80Hz. Do I have options to manage bass like an outboard crossover or something else?

you need to run a room freq plot as your system is currently configured and see what the speakers and sub in the room are currently doing. Once you have that data, you can determine what you need to adjust to get a flatter response.

Dont be surprised to see some pretty wild swings in SPL  output level vs. frequency. Few rooms are flat.

DBA. Do a search. Read the comments. Especially mine, noble100, audiokinesis. (In reverse order- Duke is by far the most experienced of all)
