My father-in-law always comments on how good my audio system sounds, so I decided to build him a set of speakers for Christmas. I went around and around on what to build, and finally decided to give it a go and build a design of my own.
The system will consist of 2- dayton 6-1/2" treated paper cone woofers in a ported enclosure, a 5-1/4" mid woofer that I have a bunch of from a parts express buyout, and a Morel MDT-20 tweeter. I just received the woofers and tweeters yesterday, and did a lookover to see what was what. I must say that the Dayton drivers seem to be well made, especially considering the price. They have heavy magnet assemblies, a vented pole piece, and the cones aren't even all that flimsy. They are definitely much better quality than the 8" MCM 55-1190 woofers I have used in the past.
I hooked up the tweeter in place of the MDT-33's in my main system. The lesser efficiency was noticeable. They also sound quite a bit brighter than the mdt-33's, and lack detail in comparison. They did hold up very well against the Vifa PL tweeters that I used on a friend's bookshelf system. They were noticeably smoother and more musical, less harsh. Overall, I would say that they are a great value, and have the same basic tonality of the MDT-33's for about $175 less (in my opinion, the 33's are worth the extra $175- I love these tweeters).
The plan is to use these drivers in small floor standing enclosures. I was trying to balance bulk against efficiency and bass extension. I feel that this will be a good compromise for the intended use.
The plan is to use a fairly narrow baffle, and use the extra efficiency of the woofers in parallel for baffle step compensation. I plan to cross them over in the 500Hz region to the midbass, which will run up to about 2400Hz to the MDT-20. This system should have an overall efficiency of around 88db/1W, and should get down to around 48Hz.
Any comments on the design would be appreciated. If there is any interest, I will document it as I go along and post some pictures.

The process of designing and tweeking a 3 way crossover would be of particular interest to me. I've not tried that yet so understanding what methods are successful would mean a great deal.
Thanks.

Thanks.

Tim,
I will be "flying by the seat of my pants", so to say. I haven't tried a 3 way yet either. The plan was to build the enclosures and mount all the drivers, measure their in-box impedance and frequency response using Speaker Workshop, and then try to design something that works. It should be interesting, to say the least!
😀
Time is my biggest limitation right now. I have a feeling this project will take it all up until Christmas. Thanks for the interest.
