DIY 2.1 System - Eekel's Mini + Dayton Audio RSS210HF-4

meira007 · 13th February 2012, 06:31 PM

Hello All

I will start here to present my current status of this DIY project: Eekel's Mini + 8" RSS210HF-4 Subwoofer.

The plan is to go all active. Thus, I will make my own version of thee Eekel's Mini with integrated Hypex AS2.100 amplifier (master + slave). I will have to change the port configuration from round to rectangular in order to accomodate the plate amplifier. Also I plan to put polycarbonate covers on the XOs so I can see them directly from the outside... niiiiice

The subwoofer I get a preliminary design of 17,6 liter closed box with a QTC of 0,634 and F3 of 48,77Hz... I would appreciate if you could comment on this also! All of you who are far more experienced than me for sure...

I will start next weekend and I will put the photos here so I can share my work.

Best Regards
André

News on the construction!

crossover parts arrived!

meira007 · 16th March 2012, 07:42 PM

So I made a template for each crossover, treble and bass, in order to study best component placement and this is the final result!

Nice, will you get to listen this weekend?

Hello Cal

I still have to make all the connections... Also I still don't have the drivers with me :S

But I am pretty curious on how will it sound... also with the Hypex AS2.100 plate amplifier.

Work goes on... soldering crossover components (bass section)!

meira007 · 19th March 2012, 03:12 PM

Both Crossovers finished 2 pairs of tweeter and bass section

I have measured 2 of the RSS210HF-4, ad here are my measured numbers.

That should help you refine your simulation. FWIW- I use it in 1ft^3, with a 2.5" D x 10.5" L port. Fb/3/10 = 30/26/19 Hz, and good for about 70-100W mechanically.

Later,
Wolf

Thank's a lot Wolf... I see that there is considerable difference between each driver, although being the same. I generally assume this to be a fail e quality control, no?

Meanwhile I have been searching a few other options for the subwoofer and it appears that the SEAS D1001-04 L26ROY would be also a good choice, which also fits my budget!

I am using UniBox to model the sub and I come out with a closed box:
Design by Vb and QPhysical Vb24,2lAbsorption, Qa20Leakage, Ql30Alpha, a3,389Vb25,7lFb46,05HzF350,12HzQtc0,649Response peak0,00dBPeak atnone

WHat do you guys think? I want a "stiff" bass but still have some little boominess... Generally I tend to like subwoofer with great "kick" but that can go low without being to boomy...
