First off I'll start by admitting I built a project without doing my homework and reading though all the great resources provided on this message board. I completed the build, listened to my speakers and was dissatisfied with my results. With that said I'll give you guys all the info on what I used in my build and see if you guys could offer up any advice on tweeking my design, its my first ever project for wood working and speaker building, so I guess part of it is the cost of learning.
I had a pair of Optimus LX5's and the woofer blew on one of them, I wanted to re-use this tweeter because the speakers always had crystal clear highs and sounded much better than anything else I've ever owned. I also like solid hardwood. My original idea was to build two solid hardwood replacement cabinets and find a woofer that was close to the original 5" spec and size wise and use the Linaeum tweeter and the optimus crossover. After disassembling the LX5's to extract the tweeter and XO I realized how dinky the supplied XO was and how nice and beefy the pre-assembled Dayton XO's were on PE (PE# XO2W-2.5K) . So I bought a dayton crossover, then while looking for a sutible woofer I came accross the Bravox 12Ohm 5.5"
My thought was 12+12+12 in parrallel = 4Ohm which would work with the Dayton XO, so what turned into a small project ended up being a 50" floor standing speaker.
Now for my results, I calculated the internal volume to around .68 on my cabinet, slightly less than the recommended .78 and my enclosure is sealed, no port. My speakers sound crystal clear, impressive detail and imaging, I don't have any measuring tools but I would say I have nothing below 175hz, the woofers move, you just don't hear any boom what so ever. They are stuffed with .5 lb of acosta stuff in each cabinet, would adding a port to my build fix my problem? Take a look, any advice is greatly appreciated.
Thanks, Keith
