Open Letter To REL, SVS, Hsu, etc., et al


Why don’t you include a cd that will actually enable your customers to properly set up their purchase from you? Telling me to choose something with ‘low bass content’ and put it on repeat is pathetic at best. There are very specific and very limited numbers of tones needed to dial in a sub. One of the above companies tells me to use track 4 from ‘Sneakers’, a 29 year old movie, as an aid in dialing in a sub. Maybe in 70 years the track will be in the public domain and they can just rip it for free to whatever medium is current in 2091.
Test tones, as far as I know, aren’t copyrighted, and would cost very little to put on a cd. 50 blank cd’s cost 15.00 retail. Include one with tones and instructions in the box. Tidal, Spotify, Qobuz, etc., etc., would also qualify as a place to put your sub setup tones, along with detailed voice instructions. 
I know many people now use automated setups in their AVR’s, but I’d bet many reading this on Audiogon don’t- most two channel systems are behind the times in this regard.
Or am I missing something?

I purchased a pair of REL S2 SHO subwoofers and I still don't know if I have them set up right.
With the rudimentary REL controls, one would have to be very lucky to integrate properly for 2ch music.

It's almost a certainty they might need placement in a non-WAF location

Download REW, buy a UMIK or Dayton EMM-6 microphone, learn how to use them and do it up right.

Failing that, well recorded material trumps test tones 6 ways to Sunday. My fav is a large pipe band recorded out of doors. When the sub is right, it slaps you right up side the head. Ditto Underture from Tommy, The Who 1969 version. A well recorded [in a cathedral with good pipe organ] Bach's Toccata  & Fugue in D in D Minor could get you by as well.

IMO, test tones on CDs are next to useless, but I've only been in this game 50+ years.

Once again, if your 2 channel speakers such so bad in bass that you need to "Dr" it with a sub, you bought the wrong set of 2 channel speakers to begin with and they should be replaced Pronto. All my opinion, some may object lol....

Pray, do tell, what perfect HiFi speakers do you own?

Adding a sub properly, i.e. with a crossover to roll the bottom from the mains, reduces amplifier load thus increasing headroom and reducing woofer distortion.

Look at the low end impedance curve of many highly regarded [by some] speakers. With tube amplification, a sub is almost mandatory.

"An articulate, extended and veracious low end adds realism out of all proportion to the numbers." - me
From REL T9/i web page:
"Because the additional speed and impact of the new drivers requires greater control or the benefits can be lost before they get to the listener."

This kind of Nonsense by REL is pure malarkey for them with $$, no skill and compromised hearing.

Do the Math!!!

It’s bleeding near impossible to integrate a sub with only a crossover control.

As a composer once remarked "Every other subwoofer I’ve heard just boomed."

Don’t equate More with Better.

Martin-Logan includes ARC with their x series. It can be setup from a smartphone. Better results obtained with the Perfect Bass Kit. It uses 5 positions. Well worth the investment.

I’ve tried setting up a few crossover-only-sub for pals and the best position is rarely friendly.
