is the Eden EX210, 4 ohm, 300 watts, loud enough?
« on: September 12, 2018, 07:28:30 PM »
Let's say the club is under 500 capacity. My amp is a Peavey Minimax. Reason why i brought up the Eden EX210 (4 ohm) is because I've seen it for $200 brand new. The reason must be because everyone would rather opt for the 8 ohm version, which is why the 8 ohm version cost about twice as much.

I would probably want one additional cab for that size of a club.  I was in such a club and the Bassist was using an Eden Metro (210XLT) and had a D112XLT as an extra cab.  Filled that big club just fine.  Not sure it would have with just the 210.  Of course if you are running through an FOH and only using your cab for your stage monitor, then the single 210 should work fine.

If you look at the EX210, which comes both as a 4 ohm cab and as an 8 ohm cab, their power handling is 300-watts rms.  The SPL (sound pressure level) rating on it is 101db@1W/1M (1 watt/1 meter distant).  That's a good sensitivity rating.  About the maximum SPL you can get out of it, if everything is perfect, is going to be about 126db (pain threshold is 120db, chain saw is 110db, loud power tools are 100db, lawnmower is 90db).  126db is very loud 1-meter away from your amp, but you lose volume quickly the farther away you get from the amp.  So the size and configuration of the room itself becomes a factor. 

Everytime you double the distance form the sound source, you lose 6 db of SPL.  So here's how that goes presuming the cab actually can hit that theoretical 126db limit:

1 meter (3.28-ft)         =  126 db
2 meters  (6.56-feet)   =  120 db
4 meters (13.1-feet)    =  114 db
8 meters  (26.2-feet)   =  111 db
16 meters  (52.5-feet) =  105 db.

As far as the  4 ohm vs 2 ohm goes, the 4 ohm cab allows you to use more of your amps power by itself than an 8 ohm cab does.  For instance with my amp WT500/800, it will do 400 watts per channel at 4 ohms.  If I put an 8 ohm cab on that same channel, I will only get 240 watts out of it because of he higher resistance of the 8 ohm cab.

A LOT of amps on the market have a minimum ohms load of 4 ohms.  That means that if you have a 4 ohm EX210, you can only ever run one cab from that amp regardless of how powerful their amp is.  If you plug in a second cab, then the ohms load goes down to 2 ohms, which is well below that 4 ohm minimum rating.  That causes things to break, burn up, and release the magic smoke, if their protection circuit doesn't shut down the amp in time.

Since most people want to be able to add another cabinet for a larger club, they typically buy 8 ohm cabs. That's why the 8 ohm version is more popular.  If your amp went down to 2 ohms, then you could run two 4 ohm cabs.  Looks like your Peavey Minimax has a 4 ohm minimum ohms load rating though, so you can only ever use the one cab on your amp if you buy the 4 ohm one.
