A couple more builds finished during down time due to the corona virus. One done for a buddy who wanted something for his small man cave. Needed it to be done for as cheap as possible as part of the goals along with being able to cover a wide range of frequencies so it would sound good for movies as well as music but didn’t have to be too loud.
I already had some Dayton sd270 dvc 10s I picked over a year ago open box for 20$ a sub. These subs like a BIG box. 4.0 cubic foot net @ 26 ish hz. Obviously this sub can’t move a ton of air but it has a nice fairly flat response in his room down to the tuning frequency.
For the mids and highs I went to the buyout section at parts express and got the 4ohm 6.5 6$ a driver and the t-25 paper tweeter @ 3$ a driver. Speakers are crossed @ 3.5k around 16$ in each 2way xover
For amplification Dayton 2.1 mini amp 80$
Counting the wood it’s just a tad over 200$ but could’ve used cheaper wood but I had most of it already and gave him a deal.
the outcome was very good considering price. Anyone would be hard pressed to buy anything for the same price with the same range and it actually gets fairly loud in his room.
The bookshelf speakers are .42 net. With poly fill they get pretty close to 80hz before rolling off.
Second build for personal use. Pretty much a toy. Tang band 6.5. .5 @35hz. Port 1x a tad over 7” This should be good for a near field application bedroom,computer etc. just got done last night 1st impression it has a very impressive response for its size and does a very nice job of filling in lows. Obviously not going to get that loud but there’s something cool about a sub this size playing well into the low 30s on a 50 watt amp at best
