I am currently designing a Ported\PR enclosure & I'm concerned about overexcursion below 20Hz...
I'm using WinISD & the plot is decent, but below 20Hz there's a leap in excursion which, if I cut using a high pass filter kills the response at 25Hz(which is what I'm focused on having prominent)...
So, do I have to worry about subharmonics - notes that play around\in concert with the main frequency being played - emanating from a 25Hz(or so)note causing my sub to bottom out below 20Hz if I design the box to allow lots of excursion below that frequency?
Let me know please - I'm scared(ripped a JBL surround already & don't wanna do that again)... o.O
I finally got my SWAGs. Hooked them up in series to one channel of my 100w Sherwood for a few hours while I had some other projects to work on. Once the tweeters "warm up" they are nice. Not as nice as my JBL's, but I digress. A/B'ed them against my Polk audio db's...sure they are louder, but don't sound as good. They get that horrible voice resonance fart-out at high volume, when the Polks keep going. Tried messing with the EQ and curves... Guess they're not going in the Jeep doors - I'll keep my water-logged $60 Polks in there.
The baskets are HUGE and won't fit into any OEM 6.5" location, so fabrication is to be expected. I figured I would put them into the rear shelf in my Corolla...not without cutting, even with the JBL/Infinity adapters! Seriously considering 'glassing a whole new panel just to make them work somewhere.
These definitely need power, not just a head unit. Still haven't gotten parameters from EMF, but .6 cubes should be enough for each driver, right? I can probably get a little more with an enclosure the size of the panel. I can really use more midbass.
Disclaimer: this is not a bashing against EMF - I'm not done yet, and I need to make these work. I'm sure it's just me, or the speakers haven't fully broken-in yet, or something silly.
I recently purchased a pair of hertz mille 3 way components, the mlk3 pa I only have a 2 channel amp for my in cars a bmf 300.2 I was wondering if there was a way to hook this set up with only a 2 channel. the crossover is only for the mid and high. I have done an active setup in the past but in my current vehicle I don't really have the room for another amp and I really don't want to spend the money on a 4 channel amp. I was wondering what would happen if I ran the amp to both the mid-bass driver and the crossover, the bmf 300.2 is 2 ohm stable, so the impedance load shouldn't be a problem. any input or personal experience would be much appreciated, thanks in advance.
