T/S parameter search engine?

toenail · 23rd April 2003, 11:13 PM

I'm trying to find specs for a Boston Acoustic 5.4 LF woofer. I've found the 5.0 LF, the 6.0 LF and the 6.4 LF, but can't seem to come up with the 5.4. I e-mailed Boston Acoustics and got a reply stating that they do not publish those specifications for the public.

Anyone know of a place I can find these specs?

Why not measure them yourself? It would be way more accurate than depending on manufacturers specs.

If I owned any measuring equipment I would. I'm in the infancy of learning about DIY audio and have yet to purchase any. I'd just like to plug the specs into some software to see what it spits out. My hope is that this would be more accurate than a WAG.

It's really not that difficult, maybe you're under the impression that you need lots of equipment. Read through http://sound.westhost.com/tsp.htm all you'll need is a multimeter, sine wave generator and an amp (other assorted resistors and wood etc)...

As stated previously- I don't own a multi-meter, a sine wave generator, or any assorted resistors. I will eventually own these things and test speakers myself so that I can determine their specs. In the interim, it would be nice to just plug some numbers in to a pre-existing software program to see what I have to work with.

Nobody out there can recommend a place to find these specs?

would an analog multimeter work? or is it not precise enough?

If you can't find the info on the web, maybe it ain't out there. Ask Boston acoustics for a recommended enclosure instead.

A cheap Multimeter (analog or digital but should have a low voltage scale of 200 or 400mV) might run you $20-$50.

You can use your soundcard as a signal generator and frequency counter by downloading a program like "nchtone".

A couple resistors costs a couple bucks, tops.

Go to google and search for: dick pierce impedometer
to find out how to measure T/S parameters.

Thanks for the tips. I had long since gotten a recommended enclosure volume from Boston Acoustics, though not without some serious prying. I finished these speakers some time ago.

Just so happens I have seen this driver in a speaker database from Audio Nova Magazine, in fact a ton of drivers are on this site.

That's exactly what I was looking for. Now I'll have to see if there are improvements to be made he he he.
