Quick question guys. I just built my first ss15 and have a 3015LF arriving on Friday. Glue is curing as i type (on my hands too). I plan to try it out this weekend with a Bash plate amp from OAudio. Here is my concern. It only has a subsonic filter that goes up to 25Hz and I worry it may even give a little EQ around this cut. It puts out 325 watts into 8 ohms. I'd hate to kill my brand new 3015lf on the first go.

I'm struggling with hornresp to find out what the max power would be assuming no high pass filter whatsoever. I assume all is ok at 1 watt but when would I run into excursion issues?

Not familiar with the SS15, but the amp only boosts down low when PEQ is turned on assuming it's still configured like my older one............

Oaudio and the partsexpress Bash are the same. Use the above to change the resistor values.

The bass boost is really a sallen key filter. When the Q goes above 1.0 then it also proves a bit of boost as well as a 12db/oct high pass.

The 3db boost, 36-40hz should be about right on a ss15.

This is my amp for my indoor HT sub so this weekend is only temporary until I find a dedicated amp. Don't really want to modify it just for a couple days.
Do you happen to know when I would run into excursion issues (wattage) without any high pass filter? 100 watts?

100 watts is fine all the way down low. However if you stay away from dnb, trance, dub, etc... kind of music, you should be fine up to the power of the amp.

Just be sensible and there shouldn't be an issue.

Really? Is the HR input screen on your website accurate? Cause I don't get good response (let alone down to 30Hz) w/the 3015LF using the numbers there or in the file "furysub_2009_try_dwg.pdf". Maybe there's another update..?

And maybe throw jbell's Stadiumhorn in there!

Though big, those may be my best bet for my dubstep/dnb shows. I won't have enough $ for more amps for a few months, so I gotta wait on the 18" THs and work w/what I've got for now (six 3015LFs and just enough to power for them).

Why not just put a high xmax (and suitable T/S 18) incher in your stadium horns?
They are more than big enough!

I don't currently have any stadiumhorns. I have the 6 drivers, however. 2 are currently in SS15 enclosures, 2 are in BFM T48 enclosures and 2 are still new in the box. Right now I'm looking to put all 6 in same enclosures (instead of mismatched) in a system that can reach down to 30-35Hz.

Default Now I understand!

What are your aims - maximum SPL and minimum frequency requirements?

Regards, Ben
