Default Can I make my speakers' bass better?

I want to buy these speakers, marketed in the US as Sinclar Brighton 460T: Roth OLi 50 review | from TechRadar's expert reviews of Hi-fi and av speakers
But I agree with the review that the bass is not well defined. The speakers are great in other respects, and reasonable.

Can I buy them and put in different bass 6.5" drivers to tighten the bass? Or fill them with stuffing? Or change the crossover (scary!)? Or just hook my amp to the high end of the biwire terminals and leave the low end unconnected and get a sub? Or put the speakers (already huge) up a foot or two on stands? Maybe glue little lead fishing weights to the woofer cones to knock them down a bit?

Just kidding on that last bit :-). I think.

Any help appreciated...

Thanks.

Hi,

Line the ports with open cell foam, about 3/8" thick, cut into a rectangle
port diameter times its length, fold and insert into the ports. It will deepen
bass and make it tighter, as well making upper bass somewhat lighter.

rgds, sreten.

Default yeah, but....

These are $750. There is nothing remotely close for twice, three times the price. so it's a valid question.

Besides, I want to know for pedagogical reasons too.

I suspect you could DIY something better for less money.

Have you heard many DIY designs?

No, Chris, I haven't, and this is exactly, exactly what I'm wondering. I can never get much idea of how good DIYs come out. People say lots of superlatives but I never hear anybody say "I put my Response 2.5 clones next to the real ones and they were identical" or "my DIY speakers completely blew away the Focals/Dynaudios/Sonus Fabers/pick your brand...."
I'm interested in DIY but in the near future won't have the time, tools, or place to build something like this. Ergo my question:

Can I fix the one problem with these otherwise great sounding speakers? Can it be done? How?

Thanks.

I don't know if this is worth the time or the expense, but bi-amping with stereo subwoofers???

fakeout, not sure if you are faking ME out, but I thought about just not connecting the amp to the bi-wire bass end, just the top. Then use a powered sub.
???

This speaker would appear to have a few good things going for it. Have you considered the possibility that the designer was aiming for accuracy, and the reviewer may not have had the time or the ability to integrate them properly in his room, so he could detect something lacking?

I would suggest you run them full range as intended and find the right place to put them that gives you good upper bass. Then get your powered subwoofer and experiment with putting them in different places, changing the volume, crossover point and polarity (leaving the mains alone), until you can fill the holes in the bass.
