Have been reading and learning so I assume not a lot of you will know me but here is my first attempt on building a sub...
Finally coming to a point in the renovation of the house, that I can work on the corner with the gas, electricity and water meters.
This corner will accommodate a closet from floor to ceiling but needs to pivot open to read the meters.
This will be done by hinges on the left side and two wheels under the right side of the sub-woofer, which will function as a TV-stand and all other equipment.
The front face of this bottom part for the sub measures 114cm wide and ±60cm high.
so, with x height = 3.74 ft x ±1.97 ft
The net volume will be at least 400l / 14ft³
There is room for three 15" or two 18" woofers, how to choose? Are smaller ones better? etc.
(I also plan on building two smaller subs to put next to the sofa as side stands)
Although I didn't decide on the type of enclosure, I thought a bass-reflex would be best suited¿
I don't know enough about PPSL but it seems this would lower the frequency in case of a sealed sub¿
The ever lasting discussion about 'how low should it go' is always a problem with HT-subs.
Can I assume 16hz is needed or what do you think about it?
Room size is about 10m x 4.5m x 2.5m or 32.8ft x 14.8ft x 8.2ft
I prefer a bit of efficiency, since I have a couple of old amps that I'd like to use.
One is A-656 Pioneer, dynamic output at 4Ω 2x190W, damping factor 70
The other is from Velleman RMS 2x155W @4Ω, damping >600
Are these or one of them fit for a HT-sub?
If there is no choice, I consider buying an amp.
What about filters? My receiver is a Cambridge Audio azur 540r.
This is not intended to be a reference sub, but how loud should it beat to give good HT experience?
Another thing I like is what I read some time ago on another forum about closing the BR-opening to go sealed in an instant for music.
Please consider I'm from Europe and have not the same options on the driver(s) as in the US, unless the shipping is reasonable.
I also can get 40mm multiplex ( a bit over 1.5") but that might be overkill and reduce the net volume unnecessary...
Anyway, I finally can design for real now, instead of running in circles, but I've learned a lot from forums.
