Very nice. Any specs (weight), or sound comparisons with the other models?
Ok--
The 109 is meant to offer the Big E sound and presentation at a much lower price point. The compromises are
a bit bigger than the 110 sub--it's 28 tall, 13 wide and 15 deep
The bigger size allows us to get every ounce of low end out of the driver
a bit heavier--about 40#.
I'm using 3/8 Baltic Birch. Baltic Birch is really the best sounding and most durable plywood.It's also half the price. It's just a lot heavier than the Italian Poplar or Okume. The 3/8 Baltic is about as strong as 1/2" Okume and stronger than 1/2" Poplar.
again--as far as ultimate volume---we have to look at the Vd of the driver ---or the amount of air moved. The BP 102 that we're using has a VD of 200 cc's. For electric bass with the Big E technology I can safely say that we'll get twice the Vd due to the vortex. So let's say 400 cc's. This is still pretty conservative.
The 10's used in an SVT are only about 113 cc's. (according to Bill Fitzmaurice).Most 210's these days use drivers with longer excursion.
The other Eminence electric bass speakers might do 150 cc's. So 300 cc's for a 210.
Most of the best 210's out there don't have bigger vd's than the BP102. So if you look at the higher end 210's ---they might be 400 on the high side.
The Kappalite 10 that we use in the Flex's and 110 sub has a VD of 300 cc's. So these cabs would be more like about 600 cc's.
These figures for the MAS cabs are really conservative. The Big E guys find that for PA and subs they're more like 2.5 x the Vd. But the transients are so crazy for EB that I've backed that down.
Efficiency is about 97db. The BP102 goes VERY low. The resonant frequency of the BP102 is 35hz. The Kappalite 3015LF is 44 hz.
The sound--
A bit different than the Flex's. They are taut and punchy with just enough warmth. The 109 is warm and punchy with just enough tautness---if that makes any sense. The two 3" mid/tweets are pretty cool. The BP102 doesn't go high enough. Just using a regular horn tweet wouldn't go low enough. These 3's are really cool. Cheap and great sounding. They go from 100hz to 20khz. We're not going very low---just low enough to fill the slight dip of the BP102. I was going to post a graph but I realized that it's changed. I brought up the mids a bit. It measures +/- 3 db from 48hz to 18khz.
Oh---it's also designed to be in the vertical position. That's why it's a bit deeper. There is a deeper "scoop" in front which gives better integration in the vertical position. One of the tweets faces up toward you and the other fires down. If you're on a harder surface it gives a bit more "spread" to the highs
( I think I'm getting better at taking pictures)
