Hi
I haven't read all the replies in this thread, a few come out has extremely important foe the OP to read and re-read. In particular post #4 a from
@Willem and post #5 from
@DonH56 ... Their latter posts were as usual very informative. My own post will simply rehash what these people and others have said. ZIt bears repating.
However good your speakers are in the low bass, however extended and distortion-free, they could be in the bass. Oncein a room , many strange to and bad things can and usually happens. The bass response is a mess with peaks and nulls.. You can equalize the peaks but should't or can't EQ the nulls. These are as said earlier black holes : Null suck power for no results.
Conclusion: Don't try to EQ nulls.
What to do then? It is a mystery to me why this has not become the de-facto standard for audio enthusiasts? Use at least 2-subwoofers. 3 preferably. It is usually better to use 3 less expensive subwoofers than one superior for the same cash outlay.. Say, the audio enthusiast has a #1500.oo budget for bass? The best advice is to get,
for the same budget a Umik-1 at $100.oo, a miniDSP 2 x 4 for $125 (The 2x4
HD is the better model but for bass purposes and most consumer subwoofers, expecting 1.0 volt input for full output, the 2x4 although limited, does work) , a $20.oo donation to REW although you could go ungrateful and download REW for free, a $20,oo donation to MSO (Multiple Subwoofer Optimizer), although you could also go ungrateful ... and the balance, about $1250, for 2, preferably 3 less expensive , likely smaller subs.. And they don't even have to be all the same ... It will take a while to get there and a lot of learning and a bit of frustration but the results are usually glorious.
Seriously. Bass require subwoofer. ideally subwoofer
s as in 2 or preferably 3. Regardless of the low end extension of your mains. You want to deal with peaks and/or nulls? Get a sub. Then get another , now with 2, you are getting there...3 ? with time and care in setup using REW, MSO with a miniDSP_ 2 x 4 HD? Heaven!
Peace.
