Are you interested in the new generation of "old school" design loudspeakers?


 

So is Danny Richie of GR Research. Though known for his open baffle loudspeaker and subwoofer designs, as well as narrow baffle sealed loudspeakers, Danny has received in for analysis and possible upgrades a number of the new "old school" design loudspeakers that have been recently introduced by the likes of KLH. Being a good businessman, he obviously realized he could offer his own version of such a design, free of the "problems" he found in those of others.

 

In this 30 minute video Danny discusses the design of his newest offering: the "Brute". Even if you’re not interested in this specific topic, you may find the video of value in general loudspeaker terms. He has made many other videos, all addressing either a specific topic, or a specific loudspeaker. There are easy to find: Go onto YouTube and do a search for GR Research.

 

To dispel any suspicions, no, I am in no way affiliated with Danny Richie and/or GR Research, other than being a very satisfied customer.

OLD STYLE!

As many of you know, I am a fan of level controls, as most vintage speakers came with.

So, I immediately checked, and the KLH Model 5 comes with a 3 position Acoustic Balance Switch. It is preset for: ’normal’, ’live’; very live’ (no position for dull).

download manual here:

 

Pre-set positions control the changes equally, so balance between L & R is easily maintained, however pre-set limits the changes you can make for your individual space.

Both my Electro-Voice and Acoustic Research AR-2ax come with 2 level controls: L-Pads, Changes relative to the unchanged woofer: 1 for the mid and 1 for the tweeter. Each: Center is normal; up any amount for dull rooms/down any amount for live rooms.

Using L=Pads with no pre-positioning, you have to work hard to get the L & R to match. SPL meter with test tones helps, then your ears on very familiar content with excellent imaging.

Independent L and R, and freely adjustable can help with irregular spaces

By the way, the prices mentioned in the video are per pair, not per speaker.

Big, I get the name, that seems like a great price for that much speaker and building them would be fun.

@thespeakerdude , why not order a pair, build them, and do a review for this thread? Seems right up your alley.
