I've been lurking on this forum for a while. I saw that REG had
requested freq responses from the members here, so decided to post
I have Spendor BC3s that I've tweaked. In addition, my listening room
has been treated with Real Traps..
The Spendors are run as a multi-way passive/active hybrid. The
tweeters and midrange are run through a rebuilt passive crossover, the
woofers are run actively via a Behringer DCX2496 (up to 700hz/24db),
but rolled off on the low end at 110hz/24db slope to dipole Celestion
6000 subs that are run through their equalizer. Above the subwoofer,
all crossover points and slopes are as stock. I end up using a lot of
I do a little EQ between 100hz and 300hz to flatten the dips and peaks
in the measurements, via the Behringer. I need to do more to tweak the
speakers' FRs, and will be attempting that once I figure out the
I have my own MLS setup, but have never quite learned how to use it. I
have a Behringer mic, a DIY mic preamp, going to an M-Audio Transit to
a laptop. I'm trying both ETF and ARTA, and I use this to play around
with my minimonitors. However, whenever I need real measurements, I
ask one of my CT Audio Society members to come over and measure with
his IMP system and calibrated mic.
Here are some system pics, and measurements. If you are in the NYC or
Stamford area, you're invited to come over for a listen.
If I remember correctly, the FR measurements are for both left and
eight speakers (third letter of file name), BASE = from 1m, 300hz and
up, while LF = 300hz and below from the listening position.
The main weakness with the system is loudness - the BC3 midrange
starts distorting if one goes too loud. The Celestion subs also dont
like to go too loud. Still, it can get over 100db easily, which is
more than enough.
If someone knows how to use ETF or ARTA, and can guide me through what
options to use, and what to measure, I'd be happy to do more detailed
measurements if you are interested.
I also have numerous other systems around the house. More on those
later. One has Quad ESL63s. Some of my audio club friends prefer my
Quad room, some prefer the Spendor room. Personally, I prefer the
As an aside, a number of other Quad ESL63 owners have commented that
mine make more bass than theirs. I'll attribute that to the amps I am
using with the Quads: Musical Fidelity MA50. With other amps I've
tried, the speakers don't generate the same amount of bass, nor the
overall quality of sound either. So, amp selection is also important
with the ESL63s.
