Subwoofers & DSP or nearly bye bye room
Ebay very kindly supplied me with some vouchers recently that gave me 15% off of anything over £100 & up to a maximum of £100 reduction :cool:
This happened to cover six categorys & luckily for me one of them was "consumer electronics" :eyebrows: So naturally i went looking about on the off chance that i might see something interesting & oh boy did i just...
Cutting a not too long story down to the bone i found a DSP device that is designed to be connected between a pre amp & subwoofer. This device feeds the sub with swept test tones & listens to the results & then modifies the output to the sub to get rid of room modes & tighten up the transient response. Or if you like it near as damn it gets rid of the room :) Now this is only suitable for active or if you like powered subwoofers which operate below 150Hz.
It can't be used with a standard pair of passive speakers, though it could be used with a passive sub if you found a suitable power amplifier or plate amp if building your own...
Introducing the Antimode 8033c Subwoofer EQ...
Now while i haven't installed the pair of them yet (yes Mark needs two of them with two active bass units) i have absolutely no doubt that these are going to make a real difference to proceedings. These things do not boost output at any frequency (though they have an overall 3Db of gain), they only cut & cut out room boom by EQing in the digital domain where a lot more can be done than with any analogue filter ;)
As soon as i'm strong enough to change out the Behringer CX3400 for the pair of DCX2496 i'll install these as well & see what they do, they should eliminate the room mode i have at about 40Hz & tighten things up nicely :eyebrows:
