On my desk at my work I'm using a 2.1 PC speakers F&D A510.
The set consists of 6.5" subwoofer and 2 satellites which are 4" full range drivers in a plastic shell. I don't know if this can be called speaker enclosure. It is just shell.
According to the specs the woofer is rated 20-120Hz and the satellites are rated as 4ohm 16W 120Hz-20KHz.
In fact the woofer kinda drops at 140Hz and the satellites start to pickup at around 230-240Hz.
There is huge dip in sound level between 150 and 230Hz. It is effectively missing around 180Hz.
I would like to upgrade the satellites with some DIY project for a reasonable price.
I am searching for a driver and enclosure plan which is easy for execution and the goal is to build a speakers which can go down to 120Hz or even 100Hz.
As the title suggests this is used on my desk so space or at least the footprint is somewhat limited. I suspect that sealed box will not do the job.
I'm placing the topic in the FR section for several reasons:
1. I'm fan of FR speakers
2. I expect the budget for 2 FR drivers to be less than 2 woofers + 2 tweeters and 2 crossovers.
3. I can't hear a s**t over 14KHz because of my age and hearing
Currently my number one candidate for the job is MA CHN-50 4ohm. It is reasonably cheap (17EUR/pc + shipping) and there are plans available from MA web site.
The designs that fit in my space are Fenlon 50 simple vented box and Markaudio CHN-50 Slot Vent Box
Do I have any better options?
Maybe some of the variants of Visaton FR10 4ohm at 12.5EUR/pc + shipping
Or Faital Pro 3FE25 4ohm at 14.4EUR/pc + shipping
Or Visaton FRS8 or FRS8M at 12.7EUR+shipping
And what would be suitable enclosure for them?
