Your hi-fi (or not!) history...from the beginning

Any kind of model number? Where did you buy them from? May yet be able to find those TS parameters and I can plug them into WinISD for you ;)

Thanks for the offer :D

The serial number is: 8900-6140-0
Size: 10"
Impedance: 4 Ohm
Power rating: 250W (Although this could be just for the amp of the sub they come out of? )

The model of the sub is Kef PSW 2010

Are there any good free programs, or books on the subject of building speakers? I did internet research but ended up going in circles with a program I had no clue how to use :p
 
No luck finding the parameters unfortunately. Only way is if you're willing to measure them!:

But that's pretty in-depth. A device like this simplifies it greatly, but is expensive:

So, I would recommend you install the drivers in a reasonably large sealed enclosure. Don't write off sealed as having no bass extension, I personally think they sound fantastic, very smooth and controlled. They do roll-off higher than a ported equivalent but they roll-off slower too (approx 12dB/Octave against 24dB/Octave) and this compliments the room gain much better.

For software, I use the free LinearTeam WinISD:

The Pro version is a bit more tricky to use, but it's worth getting to know. Input parameters of a driver according to the guidance in the programs help section. It auto-calculates many parameters so you shouldn't enter different ones over them, that's the reason it tells you to enter them in the specific order. Give it a whirl with a driver from Scan-Speak or any manufacturer who gives full TS specs.




Sorry to be OT! My Hi-Fi was originally a Pioneer Mosfet amp and 5-disc CD changer, can't remember models, I bought it all off my brother. The CD player wasn't bad, used a Delta-Sigma converter and sounded decent. The amplifier had pretty bad highs. Worst was the Eltax (!) speakers, no bass at all without the loudness button on! Sold all that to a local brewery a couple of years later for about what I paid for it, so not bad!

Went to Rotel RA-01, NAD C521BEE and B&W 602S. Nice speakers, a bit bright with the Rotel though and gave a bit of a boomy response in a smaller bedroom. That CD player was a nightmare, it wouldn't pick up CDs so I took it back to the shop where they sent it for testing. 2 weeks later they say there's no fault but unsurprisingly it still won't pick up many discs properly! Still got the damn thing, might hack it into a DAC for my PC...

Currently a big 3-way tri-amplified all DIY setup using PC and FLAC as source. Good, but still not finalised. Amplifiers are ESP P101 and SymaSym 5.3 designs. Hi-Vi M8a, Dayton RS52 and Hi-Vi RT2E-A drivers.
