I was hoping someone might have some good tips for upgrading the bass on these speakers. I love them but the bass was awful. I stuffed the boxes with some damping material and closed up the port and it’s much better but still a little wooly. I feel like if I could just get the bass dialled in they would be awesome. Does anyone have any suggestions?
Wow that is one very cool loudspeaker! Keeping the box closed and use some modern eq to adjust the response to your liking could work i guess
I’ve tried room placement adjustments. They are sitting way out in the middle of the room. I also have an antimode dsp to tame the peaks. It’s still a little muddy in the bass region though.
Interesting frequency response curve on the speaker, i wonder if this one is correct? it looks there is room for improvements
Grab your measurement gear and show us what the frequency response looks like at the listening position. 🙂
Preferably both with and without antimode.

The first line is 50Hz on Technics. The flatest one seems to be the SB6000 model.

I thought muddy bass was a frequency response issue, apparently not. Is the bass still muddy if you listening around the room?
Yes, that one looked much more linear. I also wonder what is going on in the graph above 1khz for the other speaker, it is not very clear
I put a 1 ohm resistor in series with the woofer and the bass is excellent now on HPM-900

Maybe the rubber surround or even the spider has stiffed up over time?
There are 2 electrolytic caps in the crossover for the woofer that might be worth testing also?

It's the dips that are your problem. You can see the processor doesn't want to touch them.
looking at the graph in Allen's post #6, the LF hump is usually symptomatic of a box that's too big. The internal construction is shown here: Technics 7（SB-7000） | Technics Chronicle
Perhaps it would be worth trying to block the internal vent between the upper & lower chambers?

They had a couple of versions. My version just has a single port on it and the box is one piece so I can’t block it.
I guess my question is can I drop another woofer in to replace it? Well it turns out it’s a 14” woofer so the answer is likely no.
That being said the bass isn’t terrible, in fact it’s quite decent. I don’t notice the dip in the frequency. But if there is one thing I would improve it’s the bass.
