Lilmike's Cinema T-6 - Page 4

I let it run up to 90Hz with 48dB cut, wonderfull....thx to Mike and all his work on it that let me make building a pair!!!! Astonishing, such a small driver in a big housing. Great sounding, amazing.

What is an acceptable range for the various t/s specs. I am just looking to see if there are other drivers I can use in this config. I have some 10" rockford p1s in mind, but the specs vary from some of the subs listed earlier. Thanks

LilMike,
first I would like to say thank you for taking the time to share your knowledge with the forum. I am a long term lurker, and have decided to build both one of your F20s and T-6 subs for different applications. The T-6 is going to my daughter for a simple 2.1 system. I saw that the Infinity Reference 1060w is on sale for $48 on Amazon. Would this driver work for the T-6?

How would this T-6 with a Dayton Pro-10 or TC Sounds Epic 10, compare to a sealed 3.5 cubic foot sealed enclosure with a TC Sounds Epic 10, if I build 3 of them to go under my LCR's (bookshelf speakers) connected via the speaker level outputs on the back of a Bash 300 watt amp? My goal is to be able to make my front stage sound more like a large tower setup, even though I have small bookshelf Ascend Acoustics Sierrs-1's.

What size driver are you using? I am trying to build a 10" version. Did you have any fitment issues?

Thanks,
Dave

Thanks Mike,
for ~$40 I am willing to experiment. I can always swap out the driver if I need to.

This looks like a nice design, I'm tempted to give it a go with the JBL 10" driver as this is available to me in the UK.

I was wondering if it's possible to use it with a 12" driver if I make the box a little wider?

I have a few Pioneer TS-W305C drivers that I would quite like to use here:

Now I tried to model it in hornresp, but I wanted to check that I had all numbers correctly before starting to cut the ply. I've aimed for a 13" internal width, so in order to model this I've divided all the SD values by 11.75 and then multiplied by 13. I've also done this to the VTC and ATC values.

Here's my input screen:

There is an error, "Atc < SD", is this of great concern?

And the SPL curve:

Pioneer drive in black, Tang Band driver in grey.

Now it seems to model pretty well, is there anything I have got wrong here at all as I'm still getting to grips with hornresp.

Also I'm planning to use 1/2" inch ply and also extra bracing as this box will be wider.

Thanks

Anyone have any thoughts on using this as a car sub? Joansing for another build but not ready to jump into quad 18"s for my room.
I really know very little about what's different between HT subs to car subs.

I have seen it mentioned several times that the tuning of this sub is probably perfect for a car.

Any random info/thoughts on using this in a car would be appreciated.

Seems like it would be hard to beat for <$200.

Thanks, an 18" internal depth does seem to sim well, even if it does make the box quite a bit larger.

Inputs:


JBL GTO driver in grey in 11" wide box, Pioneer driver in black in 18" wide box:


I was planning to build a pair of these, so if I can find enough room for them then I'll have to start making some sawdust. I've got quite a few offcuts already so I'll use plenty of bracing and good quality wood.

Looks like I'm getting ready to build a t-6 or two based on the Dayton Audio DC250-8 10" Classic Woofer and a Dayton 100 watt plate amp. Buddy finally wants to pull the trigger. The Dayton SA100 should be enough to drive this or do I need to bump up the wattage?

ok thanks

What do the hornresp inputs become for a box 10-3/8"?

Trying to model the JBL GTO1014 to figure out how much amp to really look for. Going to finally start my car build soon.

Seems like the JBL GTO1014 has more output than the tang band or 10" dayton for the same price.

I want to make one of these with the dayton classic 8" and a dayton SA100 plate amp. Does anyone know what the high pass filter is on this amp?

Another question, how much of a difference would the 10" dayton classic make over the 8" dayton classic?

I have been looking at building a cheapo pair of horns for my patio. They will be primarily covered and I will likely incorporate some sort of stand to get the mouth off the ground. Thinking Baltic Birch and using a spar type varnish. Can someone recommend a 6.5"-8" woofer for the T6 that MAY stand up to the rigors of being outdoors for a couple years between replacement. I'm thinking paper woofers are not going to enjoy the humidity swings in GA.

Also, anybody ever power a set of small subs like these with a Truepath kit or similar (as on 41Hz or similar)? Thinking it would be neat to integrate the amp into one of them.

hi i have a Boston Acoustics G510-44 DVC and i was wondering wether it would work in this enclosure. i would love to model this but i have yet to find a way to run hornsrep on a mac

thats great! would this also work in paralel? just asking because i intend for it to go in a car if not its not a dealbreaker just means im going to have to get a beefier amp

yes im very excited to try it out! ill be specifically looking for a car that can fit this comfortably! will this negatively affect my power handling?

Hi Mike,
I've read the thread of your tapped horn T-6. I've drawn your design on plywood, just to see if I can manage. I succeeded! I' m going to build the horn with a Jbl gto 1014. (bidding on internet, don't have them yet). You 've said earlier that: " JBL GTO1014 (make the cabinet 10-5/8" wide internally". You mean it should be narrower than the original width?
I did not draw your tarted version. Should I? What is the advantage?
I wil include a picture of my drawing. Thanks for your great work. I enjoyed working with it.
With kind regards
