Which REL sub, R528 or B2

A few years back I had an opportunity to audition a REL Studio III, JL Audio 113, and a Velodyne DD 18.

Your description of the REL is what I heard along with the difficulty of integration. Running it through the Velodyne I was able to EQ out the bloat between 35-45hz in my room. Still, its presentation lacked the leading edge speed of the others. Using JL's onboard EQ alone I was always aware of its presences in the room.

The Velodyne completely disappeared until I turned it off. This was a huge difference from the REL. I've since replaced the DD 18 with two DD 12+s. As a working Bassist I have many raw track recordings on tape and digital files and I have never encountered any timing, coloration, or timbre issues with any of the Velodyne subs I've owned.

The ability to adjust phase, volume, and EQ presets on the fly with the Velodyne's remote control takes sub ownership into fun status.

[" If you are increasing the level from recording to recording, something is wrong,"]

It's actually a matter of taste. Many LPs from the early eighties can have a great deal of compression applied during the mixing process. Or maybe one just wants to hear more bass for the hell of it.

I can increase my subs bass volume with only a very minor affect on the rooms EQ using either the subs remote volume for a slight increase or one of the many of its custom presets for a substantially EQd increase.
