Adventures in HomeCinema: Audio /3 Bass woes

As stated in the last post about my cinema, for me there are two concrete possible solutions for my bass problems, a
  • (Parametric) Equaliser (PEQ), and an
  • additional subwoofer.

After having implemented one, I will also doing the other. Not because it is bad or not working, but there are now other… “problems”.

Because of the immediate cost, und potential future additions, the chosen solution for now is the PEQ.

Parametric Equaliser: minidsp 2×4 HD

The minidsp 2×4 HD box was very easy to install: just plug the audio wires and power in, and then connect per USB with it.

I choose this PEQ because of the apparent easy and fast setup in conjunction with REW and a measurement mic. And it really was easy to quickly get good results in a timely manner.

Setup with REW

REW has a module to generate PEQ configurations, among others for the minidsp 2×4 HD.

The procedure is pretty simple:

  • measure the subwoofer at your preferred listening position
  • start the REW PEQ module with this measurement
  • configure your target curve, how you would like to have the subwoofer responded
  • let the REW PEQ module calculate the parameters for the 2×4 HD.
  • load the parameters into the 2×4 HD.
  • profit

A subsequent control measurement with the PEQ versus the target curve shows a very good approximation.

Further improvements

Bass at the main listening position is now pretty good. The control measurement shows only a small dip now, but it is not as significant.

A remaining problem now is way too much bass in music at my second listening position at my desk.

Because if these I will definitely add a second subwoofer to eliminate the remaining dip, and hopefully also get to lower the bass while listening music. Another improvement could be to use the bass from the tower speakers, even though most sources don’t recommend this.

Lettering the plates

I always like the look of colored plates, regardless if the are actually completely colored like competition plates, or just classic black with white lettering.

Therefore I grabbed some paint and did just that.

Thing learned: space efficiency is not great, if your goal is to reach everything…

After two hours later, and two rounds of color for each plate, they look great. Much better than it seemed while painting.

My Personal Budgeting

A (personal) budget is just like a plan, or a calendar: it shows things that are, things that have to be, and things that could be.

Being free to spend money on the things that matter to you as much as you can is the goal of a good budget.

There are apparently many different named “categories” or “types” of budgets. I am not going to even try to distinguish if there are different types in my approach.

For one, it seems that there are multiple, overlapping names of different things by different parties; meaning there is not really a standard naming scheme. And secondly, how you personally achieve your money goals depends on how you personally have to handle money — it doesn’t matter if it works for me, if it couldn’t work for you, but maybe you understand the idea, and adapt it to your needs.

A budget is the sum of finances allocated for a particular purpose and the summary of intended expenditures along with proposals for how to meet them. It may include a budget surplus, providing money for use at a future time, or a deficit in which expenses exceed income. [1]
I am assuming that income and expenses are already in some form allocated and are tracked. I personally use GnuCash[2], but there are many other programms, or you can use spreadsheets, or even track it with pen and paper.

General ideas

  • Income budgets are slightly smaller than the real income.
  • Expense budgets are slightly higher than the real expense.
  • Cashflow at the end of the month has to be positive.
  • Always have at least one month income buffer
  • We are interested in the overall picture. Every week could be different, but over the year it should make sense.


I have some categories for were my money is allocated, in order to easier see were something can be adjusted.
  • Income: Everything you earn at your job, gifts, dividends, …
  • “Hard” expenditures: Rent, utilities, … everything you have to pay, that is basically out of your control.
  • “Soft” expenditures: Food, gifts, … things you need, but are more under your control.
  • Long Term Savings: personal retirement provisions
  • Short term savings: bigger financial spending (vacation, bigger subwoofer, …)
  • Buffer savings
  • Fun Stuff: Books, Games, Music, Movies, …
After writing it down this way, this is basically my budget.

Income and Expenditures are at least predictable and can be budgeted. Just check what always has been, and think about what is going to happen. Gifts can also be budgeted: you know when people have birthdays, and what gifts are expected.

Long and short term savings can be automated. For short term savings just use a suitable second account (for example “Tagesgeldkonto” in Germany). If you do not want to automatically invest in your long term savings (you should), then you could also just transfer this temporarily to a different account.

Buffer savings don’t need to be much. They are just there, to get to a positive cashflow every month. If there is enough buffer savings, this budget can be removed for the time being, and spend on other things.

Which leaves the remaining budget for fun stuff. This fluctuates a bit, because peoples birthdays are not regular, or some other expenditures are not every month. There are two ways to deal with this: use what you have for the month. If it is less, then it is less. Or calculate the average for every month.


Don’t be too hard on yourself, if not every budget is working every time. Life happens. If you spend too much one month, then spend less the next month. Or adjust the respective budgets.

There is a reason you should have a buffer on your main spending account, and under-budget income respectively over-budget expenditures, and have dedicated buffer savings.

At the end of the year, we want to have maximized our goals in term of savings and fun money, while also don’t have to be stressed about paying the bills.
