If you own quality monitor speakers you want to read this new review

I think I’m at the point now where I don’t believe any first-person reviews of anything unless they are comparing A back-to-back with B and they have some pluses and minuses for each.

I wish you and some of the others posters would read the details in the review regarding the differences between regular sub-woofers, like your 

OP LOL no one reads anything they just spew opinions, right or wrong. Welcome to the machine.

@dbphd asked, " What’s quasi-anechoic mean?"

Usually the term refers to loudspeaker frequency response measurements taken with a "gated" measurement system. This is a system which turns on the microphone long enough to capture the output from the speaker and then turns the microphone off before the first reflection arrives. This way the reflections are effectively excluded from the measurements without the room actually being anechoic, hence "quasi-anechoic".

The technique is only good down to the frequency where a whole wavelength can be captured before the first reflection arrives. So a different technique has to be used to get good data at longer wavelengths. John Atkinson of Stereophile close-mics the woofer(s) and port(s) at these longer wavelengths and then splices the curves together, and this is the most common technique.

Well, their speakers seem to have some very positive reviews. They are very attractive to boot.But I’m not totally understanding why that sub would be superior to a couple of carefully set up conventional subs.I would love to compare and listen for myself though.

I did for MANY years. Look at my page you will see the "Band Pass" speakers (SAT "stack and test") right next to GRs servo SUB system. The 8" Band Pass MB (mid base) enclosures work PERFECT. It can go 3 tiers high with 9 drivers per column, for 10 foot or higher lids.

The difference with my set up it is VERY directional. 100hz to 300hz is VERY musical. It’s also VERY directional. It is not OMNI present like 80hz and below, SUBS.

THAT is the difference when you separate the two. I been preaching this for over 4 years HERE I been doing it to one degree or another for over 25 years. NO BASS of any kind in the monitor enclosure. Separate the Mid Bass from the Sub system, ALSO.

MB and SUB do not do the same thing or ACT the same WAY...

The actual distortion is BELOW 5% in the bass region 300 hz <. NOW
Mids and highs, will NEVER hit 1%. NOW

With Narrow baffles, phase plugs (to eliminate BACK WAVE distortion), narrow planars with ZERO enclosure issues (like cone driver), we can time align the enclosures to the room with height, location and to each other at the drivers seat. We’re talkin’ The Pinnacle of Precision and flexibility in just about any environment. up to 25,000 cubic feet. Total Immersion, not just a frontal assault so to speak. :-)

Did I mention a reduction in room treatment by 1/2 and 1/2 again by going kitty corner..

It eliminated BASS everywhere in my case the neighbors swimming pool. It went from WAVES to a little trimmer every now and then..:-)

I suppose IF I went with a single PS and a VERY good ribbon with a NARROW baffle I could get very close in a small room (less than 10 ft in any direction) and fewer drivers in the band pass. 1 driver per side could work, BUT the height of the BP driver is directional.. WHERE do you want it pointing? At your feet, your chest or your head.. It does make a BIG difference..

A small room (less than 10 ft in any direction) with BP enclosures is now a single 10" servo sub room.. No kidding it will smooth right out at the seated position.. THE HOUSE quits shaking because of so many sub enclosures, I think at one time I had 12 12" active drivers and 6 passives. I use a pair of dual 12" OB servo, its over kill, one would do it.. WITH MB columns and DSP.. I use 12K directly coupled to the drivers.. NO passive XOs. All active..
Cone control actually takes place NOW. It can't with passive XO.. Anything in the path.. NO CONE CONTROL for the overshoot.. only springs on the drivers..

It’s a good idea.. One of the better ones for the money and what they claim they do.. They actually WORK.. It was the 90s before British speaker new what BASS was much less SUB.. It didn’t exist their, did it?
Just kidding, kinda..

Tejay, in your review published review you mention that you had jumper cables made to connect the monitors to the sub.  So would it be correct to say that you connect your monitors to the sub and then connect the sub to your amp.  You set the crossover frequency, phase, volume in the sub.  If so, I can see why it is so easy to integrate.  Great review.  The only issue I can see is having the veneer of the sub not match the veneer of your speakers if your using another brand of monitor....could bother some people.
