Low-Cost PMC-inspired TL Monitor with DC130A and DC28F

[xrk971]

I was inspired by jmascreen’s efforts and installed the passive crossover from my Vanguard speaker into the foamcore TL. It went inside without a hitch and now using RST28F tweeters with DC130A-8. The speaker sounds great. Very nice balance overall and great bass.

This definitely deserves to be made in wood.

Hi Jmascreen,
Do you have some more photos of the build of your speakers showing how you did the j get al TL channels etc? The speakers look great. Also, a shot showing the details of the front baffle. Did you recess the driver plate on the tweeter and woofer? Also, are you using the passive XO or doing this actively?
Thanks,

Sorry for the delayed response, got busy listening to them Here are the images

Thanks for sharing. They look great and I like your attention to details like the radiused exit vent, the rebates, and the internal damping foam. I bet they sound great.

Yes they sound brilliant

Trying out a new woofer.

SB13PFC25-08 sounds very good. Great bass extension.

Can I swap the drivers directly without any changes to enclosure also any changes to crossover?

I’m using a different XO but you can try. It might be close because similar 8ohms and sensitivity. Sorry I can’t help with anymore details as this will be a commercial product soon.

Congratulations and best luck for the commercial version of it. I am sure this will be going to sound fantastic

Do you think that the Mark Audio CHP-90 could "play" in this enclosure ?

The TS parameters are similar in Fs, Qts, Sd, but Vas of CHP-90 is a bit bigger. It would probably work ok but I can’t guarantee if it will be optimal. Of course, you are on your own with the crossover.

One good thing working on your favor is that it’s a wideband driver so the breakup behavior is very controlled and the crossover should be simple.

I intend to try it as fullrange widening the enclosure a little ( to 7" maybe) and I will see. So = 35inch 2 and maybe it works .

That might work - give it a bit more volume.

I don't get "encouraging" results . I dug these out of my closet. I'll probably install them (new baffle of course) & see what I can do with the crossover

Do you have a TL cabinet built and you tested the woofers in them? How do you mean you are not getting encouraging results?
