My system lacks deep bass response—below approximately 65Hz—while the speakers have dual 10” woofers per cabinet; Braun LS200. The amplifier is an integrated amplifier Braun atelier A2. I normally don’t use Loudness button and tone controls (both bass and treble knobs).
In fact, the Braun LS200 were launched with their own amplifiers which would be attached to the recess at the back of the cabinets modeled Braun PA1. The PA1 literally has a deep bass adjustment knob which allows user to boost or cut deep bass output by +/-3dB. The deep bass is referred to 25Hz frequency according to the user manual. Nevertheless, there’s an alternative choice for amplifying these speakers. It’s a separated component launched for them as well which are Braun CC4 and PA4, preamplifier and power amplifier, respectively. The CC4 also has deep bass boost adjustment where deep bass is referred to 20Hz and level is 0-6dB range.
As you can see, it’s likely that the LS200 speakers were designed to have deep bass assistance by electronic. And, I couldn’t agree more with this idea. As mentioned earlier, I use an integrated amplifier, A2, with linear mode operation—never use Loudness and tone controls.
I’d like to ask how can I get deep bass assistance with the lowest cost, except using anything cosmetics the signal such as Loudness, EQ, and Tone Controls?
Actually, I also have the answer in my mind that is using a subwoofer. However, the question was initiated because my subwoofer is now being repaired, Lol. And I thought I already have four 10” bass drivers in my hands, so is there any way to maximize outcomes from them?
I would love to hear everyone’s thoughts.

Any cheap analog simple 31-bandEQ can do the job and, in addition, you can correct most of room mode issues.
I use a very simple "EQ231 31-Band Soundvoice" sold by Amazon and other online retailers - check if it is delivered in your region.
I've paid U$160.00 in Brazil with all the taxes and freight.
Speakers close to the wall behind them and your place of listening in the opposite wall.
These are the places where maximum pressure occurs and standing waves tend to sum rather than cancelling out.
Anyways, you do need an eq to remove the excess boost caused by standing waves in certain frequencies.
Worst place for listening bass is far from walls in the middle of the room, where big bass deeps will occur and there is no eq or subwoofer that will correct that since anything times zero (the null point) is zero.
Along the walls many bass irregularities will occur, but since they sum, you can attenuate them.
Remember: standing waves interferences are made of sums and subtractions.
Equalization/amplification is based on multiplication (amplification) and division (attenuation).
Division is not the inverse of sum and subtraction is not the inverse of multiplication.
But, any sum can be reversed by a division.
Not all the subtraction can be reversed by multiplication. since if the subtraction results in zero there is no way to reverse.

Braun use eq so why won’t you? You can only boost in a controlled way with eq.
If you want deep tuneful bass 18Hz and up build a pair of Volvotreter type tapped horns.
Power them with an amp that can do low pass XO and the odd room mode PEQ to control things and integrate them into your existing, job done.
