Hi Ryan, impressive response for such an economical design! Another great video, your analysis of the measurements is second to none and really educational and insightful. A couple of requests: a) what resolution/db increments are you using on the vertical of your graphs? On my screen it's difficult to read the vertical axis. b) would you mind presenting the horizontal measurements using a Geddes style polar map please? The Omnimic software which is free to download from Dayton Audio is easy as to import your horizontal plots and with a single click present the polar. I find these very revealing of the off axis performance. Keep up the great work! Cheers.

Maz 4bz I use 5db increments. The red horizontal line is 80db. I do like polars and do find them useful. It’s an extra step I normally don’t bother with because it’s the same info, just presented differently. It is a better presentation though, so I’ll consider that in the future. Good suggestion!

Another reason for no port is the gradual phase change in bass relative to ported. When using an electronic crossover, not ported will crossover smoother due to smooth phase shift.

I remember when you tested the midwoofers they were a bit off in T/S parameters and one rolled bellow 300Hz when you measured them free field - maybe good idea you put them in the closed box. So, the tweeter isn't as good as, say SB ring dome, which is a 10-15 bucks more, and the dip at 4k is even in data sheet. Inefficient, ya small, sucky midwoofer, well, maybe other ones would have 2dB more. But, the enclosure looks really good, shape is nice, no square edges - no way you could get something close to them at BB or other store even at twice the price, not with cabinet like this, so don't complain. I know, we all do that. It's OK speaker - many factory made ones measure worse.
@pliedtka
5 жыл бұрын
I forgot to add something - some two months ago I did free field measurements with my old Clio, well I can say that the ring dome SB is toughest tweeter I ever used. Forgot to limit the low frequency limit and the sine sweep started at 10Hz w/o crossover. My eyes almost popped out when I saw the the dome moving some 3mm p-p. It survived the sweep no problem - no demagnetized neo motor, everything measures and sounds fine. So, adding to your tweeters test - it's a good product, other than some Fs and other inconsistencies in production samples.

It's sad those Dayton Audio drivers did not perform so well because the end result otherwise turned out really great. I really like the woodworking you did on the cabinets. It does leave me with one question, what are good budget drivers? I myself have used SB Acoustics drivers (nrx woofers) in the past in a more budget oriented build and got great results. My units measured ruler flat apart from some baffle related anomalies. So for a future build I recommend having a look at some of their drivers.

Martti Innanen no it’s not. That XO type only makes it in phase in one spacial location. Outside that location the drivers slowly go out of phase. Doesn’t matter what type of XO is used. The only way to avoid it is to XO sufficiently low and/or place the drivers sufficiently close together. Which is basically impossible.

Brian Steele I don’t generally practice the idea that closer to a wall means less baffle step compensation. I do my best to flatten it down to the same level as the bass, and find this sounds best with all speaker applications. Maybe a little less with nearfield applications. This was a very simple XO though and I didn’t get it razor flat. Not bad though for 5 cheap parts.

Hi, sorry I have a question unrelated to the video I'm new to speaker building and I couldn't think of someone better to ask. I've been looking online for hours and hours now and haven't found a concrete answer. How do you determine the proper port diameter? My project uses two Dayon Audio ND105-8 on a 0.70 cubic ft enclosure and I've got a 1.75 in diameter port I want to tune to 45Hz, but after doing a lot of research im not sure if it's the proper diameter. I've read about proper port surface area, length, tuning frequency but couldn't find information on how to connect that to each other to figure out the appropriate port diameter. I would truly appreciate any help you could give me with this. Also, keep up the good work! I really like your videos since it goes more into the technical aspects of speaker building.
@ImpulseAudioSpeakers

Javi J No problem about an off topic question. I haven’t done a video about box design yet, maybe I should. Generally my advice would be to use a box model program like WinISD or unibox. You can input all the driver parameters and then model the port size and tuning. WinISD is not very user friendly, but unibox requires excel. There are some other program options though. And I’m pretty sure there are some videos available how to use them. I have a few other things on my plate but I may do a tutorial or something.
