Thanks Mike! I'll be making more subs/speakers with this style of construction, it's relatively simple to finish, no veneering, etc. However I do need to work on my gluing and finishing skills, in person it's not hard to find flaws
I had a chance to turn them up yesterday. With the nearby wall and floor vibrating, the cabinet itself had hardly any movement. So the dual opposed configuration does work - mission accomplished
More importantly, how does it sound?
It sounds good...! "Solid", if you know what I mean. It's gone straight into the HT though and is connected to the sub out on my inexpensive AVR... sorry
Having said that I'm becoming increasingly convinced when it comes to subs that as long as you have good quality ingredients, it's all about location, location, location. (Mixed metaphor...
)
Beautiful! I like the way you mounted the woofers from the 'inside'
Thank you
I was originally intending to mount them from the outside but I just decided they looked like they would be better inside. Having done it, I think I prefer it and will probably do it this way in future unless there's a reason not to. BTW I'm not sure if it's clear from the diagram but the bottom/plinth is removable, there are bolts between panels F and G.
Measurements when you have time, this sub should really give you some kick in the >50 Hz range!
Sure. Bearing in mind that as I said the box is smaller than I would have done if I'd not already had most of the panels cut for a single driver, red is the nearfield response. The early rolloff in the response from 80 suggests a fairly high VC inductance - seems consistent with about 3 mH in the model. BUT! Blue is the response at the listening position. With
no EQ. I kinda knew how that location in the room (for the sub) behaves - bit of a boost in the 30s, dips around 60-80 - but I wasn't expecting it to work out that well! Anyway, so once I get my HT EQ back online I'll tweak it a little bit, but there really isn't a lot more that needs to be done.
