    Which is why I restrict the back wave on my Heils. It really helps imaging.

    If you've been listening to the 2225, the 2235 will suck the life out of your vocals.

    I've never been happy with the 2205s reconed as 2235s with factory kits in my system.

    BTW, when they were...

    I had initially figured 60 degrees based on the acoustic wedge foam. But that actually has 10 wedges per 30 centimeters, so is a bit off (wider than) of 60 degrees

    Actually, turns out that when...

    You are hearing correctly. There is ~1-1.5 dB peak at ~1kHz. I've "voiced" the speakers to be a bit hotter in this area because it brings out intelligility and is hard to totally mitigate from the...

    Would you know L200/300s if you heard them? If I did a video of the L200/300 vs the Mermans, A/B, at the same volume level in the same room, would you still find a way to fault it? :confused:

    You...

    Certainly you hear differences in the room acoustics. But if you can't hear the difference in the clarity, presence, microdetail, and enunciation in the two videos, maybe try different headphones.

    Obviously some money invested here.

    Rob,

    I came up with a new concept for the Heils that you may want to try. I've found that it increases the volume by ~0.5 (measured on a Quest 2900 Type 2 meter) and adds clarity and...

    JBL does this on a lot of stuff now, including the new L100 classics (butyl rubber), though it would seem than much of this technology has trickled down from their "professional" automotive line.

    You would want to use the N1200 crossover and replace the existing N2400 with an N7000 between the horn and the tweeter.

    But know that the D130 was not used with the 175/horn. It was the 130A...

    Mounting Screws for a 2241

    I'm doing some work on the Merman cabinets and noticed that builder used wood screws to hold the 2241s. :eek: I want to change these to Allen keys/Tee-nuts. What is the better fit 1/4-20 or 10-24?...

    Knocked His Block Off

    The Mermans do females great, but there is a suck-out at 250 Hz, with a dip below and peaks above and below the dip that affects male voices. I attribute most of this to the cabinets that are made...
