Hi Guys, This forum has given me lots and lots of information of several owners so thank you all for sharing your insights and most of all pictures.
I would like to build a speaker based on the interface D. I ran into a nice set of two VMR and ST350b speakers and suddenly images from my youth popped up. I have been an Electro Voice fan since my teens end 70's and have actually I build a copy of the Sentry III in that time frame. The Interface D was lost in the dungeons of my brain ready to pop up after seeing the VMR.
I have the luck that my nephew has a great wood shop with CNC machines that was owned by his father (my uncle) and his father (my grandfather), so building speakers has been a passion for over 35 years and I have build many models in the HiFi and PA space.
I am not an absolute vintage geek, love those old designs but I don't need to actually recreate the original. I do want a good sonic reproduction of the design so I am looking for the original stuff.
What I want to change is the geometry of the enclosure. I want to give it a slightly more modern appearance but still remain truthful to the original design. This means that I want to make the unit the same height but a more shallow front panel but deeper. This will give a width of about 15" with a depth of 22" with the original height of 32". (this is actually the enclosure 90 degrees turned). I don't want the passive crossover in the open on the bezel, but keep that clean.
The advantage is a nice speaker to look at in the living room (higher WAF) with a better dispersion as there will be less interference from the front panel.
Volume will remain the same so the LF properties will remain unaltered. I need to find a 12" speaker that will be up to the task (thinking on a Sentry 500 driver).
I am also considering making the unit powered with a dual amplifier module and keeping the VMR/ST350b combination passive.
A few questions that maybe some of the forum members who own an int.D can answer;
1. What is the distance between the bezel and the enclosure (the height of the gap)
2. What is the size of the port? I have seen a round one that seemed to have no depth, and I have seen a square one in two parts that had a dept of something in the range of 8" to 10".
3. I have the schematic of the very straightforward crossover but some of the values are unreadable.
Can anybody help me with these questions?
Thanks.
