Electrovoice Phoenix

Giacomo Galassi:
Hi everybody. What do you think about Electrovoice Phoenix PX2181?
I have a JBL Vrx rig (4+4 cabinets) and I've tried:
jbl srx 718
jbl srx 728
proel edge 121sp (with B&C 21'' woofer)
acoustic line B118

None of them had the sound I like. I've just bought, after years of tests, four PX2181.
What a SUB! Even at low volume..
I drive them with a pair of QSC PL380 (instead of Itech 8000 which were used with SRX).
Anyone with experience with these subs?

Tim McCulloch:
At the 2007 NYC sub shootout, we did TEF sweeps of ~16 subs and decided which models we'd audition the next day.  Neither the Phoenix nor the L'Acoustics 218 made the cut.

What, exactly, is the sound you're looking for that nothing else has/had?

The Phoenix 2181 hasn't seen much discussion around here so you might have to wait a bit before someone has comments.

The PX2181 has a lot of upper sensitivity, and with the presets it will play fairly low (at low level), but will run out of output in the bottom at less SPL level than the other subs you mention.

It is already 3 dB down at 50 Hz, and drops at 24 dB per octave from there.

That type of response works OK for some program material, I used cabinets in the 1980’s with similar response.
Edit: Looking at the response, again, I never used any cabinets for bass that rolled off that steeply, and high, other than Yamaha 4115H, but that was in the 1970's, for side fill.

Hi,

The PX2181 subs do pack a lot of punch for 18" subs, but as in previous posts and the frequency response shows they do not play very low. The EV preset has a +5db boost at 45Hz Q2.0.

One massive flaw with these subs is that they have a 2.5" voice coil. I was rather annoyed with EV when I had to replace a driver! They are certainly not a sub that can be abused with some monster amplifier!

On a more positive note, they do fire a long distance when coupled together and do sound rather musical.

Giacomo Galassi:
You're right, EV settings have a boost at 45 hz and a cut at 100 hz (i think to shift the phase).

And yes, they don't play very low, but for "hi-fi" applications (eg. jazz, soft rock, lounge music) i still have JBL srx718 that sounds great at lower volumes.

But all that I want from them, was a big punch at high volumes and at far distances (up to 40 meters)..
