I've been looking at the non-SEOS wave guides for their radiation pattern and am having no luck. Anybody with that information? I'm really looking for a 60x40 constant directivity horn with a 1 inch...

Another vote for NOT using the 10X. It is horrible for a speaker covering. Like someone mixed sand and glue.

Most people with reasonable hearing can hear a little below 20hz. With even a moderate bass signal I can hear 15hz. Below that, the debate is ongoing. In some rooms it can be felt, such as wooden...

Any body try the Dayton PA380 in a 2 way?

Looking at the FR graph on Parts Express, it seems to be able to do 1Khz with little trouble. There is a huge peak where I assume the breakup occurs leading up to 2Khz, but if the FR is accurate it...

I'm going to answer my own question...yes plugging the port makes the bottom end roll-off more THX like. No more peak at 120 Hz, just a smoother bottom end. Losses a bit of the boxy sound I hear from...

Has anybody tried blocking the port on either the 215s or 212s? Just wondering if it would produce a more THX-like roll off. I have a 212 coming my way that I am going to use with an active crossover...

I would like to use this coaxial with the Selenium DT220ti...would there be much of a change to the crossover? I already have the CDs, so why not make use of them?

Thanks,

I like overkill...and for reference, the FTWs will only do 127 db at 1m at 20 hz. That is exactly 115 db at LP. Just a little more headroom, for redirected bass, that's all ;)
