SPL Roomsize Calculator

**-justin-** · 05-03-2002 12:39 PM

I made a nifty tool, an online calculator (with valuable help from Brad Starobin -- a Polk Engineer) that recommends a subwoofer choice based on your room size and type of main speakers used. We would like you polkies to test it and make comments and suggestions prior to making it public on the website. It's located here:

http://www.polkaudio.com/home/toolbox/splroomsize/

Play around with it -- is it useful? Easy to use? How 'bout the title? Getting an error? Anything that pops in your head!

Email me directly (webmaster@polkaudio.com) with any feedback you may have, or post it here.

Thanks for your help guys!

I'll be damned. One of the recommended subs was the one I bought. Polk didn't have the 550 back then, but I do have the 350.

No errors or problems for me. I couldn't find the SDA 1.2's listed though.

It seems to be coded in PHP.....

Peace Out~:D

It's a nice way to do it.
But my question is when are we going to see the replacement sub for the pws1200.
Can we expect a new sub that can play solid down to 20hz??Or lower??

Very nice! :)

Now what can you do about my other settings like Surround Delay, and reverberation levels (BTW, I have a Yamaha)?

In reply to:
"i think i want to shoot for the performance of my car it is past 126 db"
You are going to find it VERY hard to hit 126 dB in a normal sized room. You could do it in a closet or something similar in size to a car interior. Remember, sustained exposure to that kind of SPL WILL damage your hearing permanently. You don't want to be wearing a hearing aid when you're 35, do you? It does NOT help in picking up babes.

Very nice program, but I'd feel better if you didn't abandon those of us with vintage Polk SDAs. Your Polk subwoofers will work just as well with the vintage stuff as the new stuff, right? Why limit your potential market unneccessarily?

Yea, my sentiments exactly with the vintage Polks...............................come on Justin, break out your spec sheets and calculator again and get us that info..............................:D

To all those asking about adding SDA and more models to the sub calculator. It will be done. We are trying to avoid having a pull down menu that is a mile long with every conceivable model Polk has ever made. That will take a little time (a few weeks) but we will get it done.

Paul:

Thanks very much.

**cgravil** · 05-29-2002 09:55 AM

just one thing.... I've selected my little rm6200 package... and it matched the psw450? or DUAL psw450's!!!! Damn I like bass, but um...

**"Polk" Paul DiComo** · 06-05-2002 02:24 PM

Ooops. That is a mistake. I fixed the database. Try it again. Thanks for pointing out the error.

**rskarvan** · 06-05-2002 04:18 PM

Very nice !

**cgravil** · 06-13-2002 01:56 AM

Paul.... life is good... You are recommending 250 now.. and the DUAL 450's are listed as "Stupid Loud" Rock on!

I'm still thinkin about gettin a dual 450 on....
