    Another Helium build. Very happy with them, thank you Scott!

        Using Minimus7 Enclosures, needs a few more finishing touches.

          I brought the Heliums to my friend gtg in Plainfield, il. A bunch of avs guys were there. A great time had by all. All the guys were very impressed with the Heliums. With lots of high sensitivity designs there, they of course could not play as loud but they sure did sound really nice and clear and really threw out a wonderful image, they disappeared into the room. The only other speakers that had this disappearing effect (the sound stage and image are there, but don't seem to be coming from the speakers themselves) as I call it, were Jeff B. designed Fusion 8 towers.

              My friend Mike's. He's Eng-399 on AVS. He's got a thread on the gtg which doubles as his theater build thread too. Those are 4 Stereo Integrity HT18's tuned to 16hz. His mains are Behringer B215xl's. It definitely rocks!

                I love those pictures of the Heliums getting to hang out with the "big kids". Sounds like a fun weekend!

                  Did you have a sub? They really need a sub to make up for what they're missing on the low end.

                    We played them with and without the subs on the wall that you see in the pics.

                      Re: Helium - a true micromonitor

                      I recently installed my Heliums on the wall next to each side of my TV which is also mounted pretty high up on the wally. As I expected the baffle step circuit greatly increased the bass all the way into the mid-bass about 200hz. I was impressed to have a solid response down to 60hz! I employed a great little app called equalizer apo on my laptop along with REW to flatten it all out. After doing so, these babies sound even better!!

                      Here is my REW file. https://www.dropbox.com/s/alwh7ae5un...%202.mdat?dl=0

                      I don't have a HPF set so i suspect they'll sound better once i get a proper receiver. I have so far eq'ed flat across the lower octaves. I noticed distortion rising towards 60hz so i'm going to need to re-eq when i get a chance.

                      hope i'm doing all this right. all measurements were at the MLP using a mic stand. I can't help but wonder if i should take measurements within a foot or so directly in front of the speaker in order to better flatten the response?

                        Re: Helium - a true micromonitor

                        If your listening position is pretty well defined, equalizing there should be the best choice. It might be worth moving the mic a few feet in each direction as a sanity check to make sure you aren't over equalizing a localized room-induced cancellation. The more sophisticated room correction algorithms average multiple mic positions.
                        Keep an open mind, but don't let your brain fall out.

                          Thanks Scott. I will try a couple more spots on the bed to take measurements. I guess I should consider what my wife hears also... Ha!

                            Another helium build. I went with solid walnut on these so we will see how they hold up. Thanks for the design Scott.
