Another Peerless woofer Question (CSX-10)

[LageB]

Hello folks and experts,

I have difficulty to decide on a good woofer/subwofer to match with pair of Fullrange Fostex FE168S drivers (XO around 160Hz)

Has anyone experience/opinion on Peerless CSX "10 driver (CSX 257 H - Order ID: 850146)

Above driver looks interesting to me and I plan to use it in a 50-80L sealed cabinette.

Any opinions is much appreciated!

Thanks in advance

LageB 🙂

I've been using them to fill in the lower freqs on some B&G RD50s. I have them Xed at 350 Hz in sealed .8 Q enclosures and they sound very good. My only negative would be the stamped steel basket. So used to seeing cast these days, the stamped kind of feels cheap.

Pete,
I am glad to read you are happy with the sound of your CSX 10" in a sealed box.

You have them in sealed Q=0.8. Does it mean Volume around 33L (1.2 cu.ft) ?

If so, what was the reason for that particular volume? I am quite new to this Loadspeaker DIY thing, but, I got myself a speaker software (LspCAD) and when I set Q=8 I get 33L. With this volume I also get some limitation to the cone excursion. Was it because of cone excursion you decided on your Box volume, or was it other reason ?

Regards
Lage

I made a fully stuffed 1 ft^3 enclosure to put it ~.8Q. I always intended to use these with a sub, but as you can see from the pic, they do just fine on their own. This is from the listening position using them full range.

An externally hosted image should be here but it was not working when we last tested it.

Nice curve you got there Pete!

It seems you have a steep High pass filter for the CSX that is Xed around 40-50Hz !?

I had hoped to use the CSX 10" only with a subsonic 2nd order active filter as low as -3dB at 25Hz....
