I want to look up the vintage drivers in Thiele-Small Loudspeaker Database

BentMike

I don't see Polk Audio in the Thiele-Small Loudspeaker Database. http://www.thielesmall.com/database.asp

:question: Who manufactured the vintage woofers and radiators in the Monitor X series?

If you know that these drivers are NOT in the database that'd be good information for me.

Thanks,

Welcome to Polk. The mid-woofers and PR's were manufactured by Polk Audio as are most of their drivers. A few exceptions are the Peerless tweeters used in the 70's-80's and the Vifa tweeters used in the LSi series. If you have the model number of the mid-woofer (ie. MW65xx) I may have the small parameters.

It's not extremely difficult (and frankly more accurate for any given driver - especially a vintage one) to measure most of them oneself.

Two ways to go:

The easy way (maybe too easy; takes all the hobbyist fun out of it):

The fun way (and one may use s/w and a computer sound card in lieu of a signal generator - i.e., "audio oscillator"):

Nice replies guys. I am heading towards making my own measurements, but I am currently trying to understand some of the theory and tools.

Maybe you can recommend a good book or two?

I have access to a nice Tek TDS 540 (4ch 500MHz digital storage), and an FFT spectrum analyzer Stanford Research SR760. What I don't have are microphones or sound generators. I have some simple function generators. I have the impression there are CDs with useful sound files, but I haven't gotten into that yet.

I was expecting to see listings for Polk drivers along with all the usual suspects, but not so. That made me wonder if they spec'd them for someone else to build. No Polk listing in the T/S database.
