Adding sub(s) to Belle clones (version 2)

Recommended Posts

I do like the idea of using the MiniDSP HD 2x4 to get more control over the room since I have the amps needed.  May go that route.

Have you tried it yet? I just bought one yesterday. 

I had been doing some renovations at my home and when I put my basement system back together this week, the SA1000 Dayton amp fried. It had been temperamental for a while now so it was not a huge surprise. I really like the convenience of it and like the high pass filter as most of the speakers down there are small (except for a set of Belles that don't mind being cut off at 80hz since they don't do much in that range). I was going to get a new SA1000 but thought they were a little on the pricey side for what you get. So i got the miniDSP 2x4 on the way. I will use a small Crown amp (which has a lot more power than the Dayton does) for the two subs i have down there.

I will report back when up and running.

With all the experience in this thread I thought I would ask.....

Could you put two Tuba HT's between the mains and place a Plasma TV on top ?  and if so how should they be placed ?

Yes that will work and I used my one very large tuba sub as a tv stand for a few year until I got this Yamaha speaker for a center speaker, first off make sure you have the driver that inside the box as close to the ground. I also placed a thin peace of rubber material under it and under the tv. Not that it needed it as the tuba when built the right way, will not vibrate or rattle any, the tube sub box I had , I built using 1” mdf and it was close to 110lbs with the Dayton Audio mkII 15” driver. So she was a heavy B!!!!!
What ever box you use and if possible, just make sure the driver is a fair away fro
The tv and that it does not vibrate
Good luck and post some pics
I’ll look and see if I can find some of my old tuba sub, but for now here’s a pic of the Yamaha center speaker I use as a tv stand

Yours if you want it. I wont be messing with anything until my mini DSP gets here and I am out of town next weekend. Once I get everything broken down, I will give it a once over and send it off to you.

It's size isn't hard to work with at all...but don't want it to be a coffee table, though. 

As the guy who promoted the "coffee table sub" which was a LAB 20 sub from another forum, I only called it "coffee table" because I had to lay it down in my small basement condo room.

 

I just designed longer version of it that goes down to 13 Hz. That being said, I would NOT recommend either one for your application, since you really need to cross at 100 Hz.

 

For the lowest distortion possible with, I would recommend any of the Bill Fitzmaurice designs, the F-20 (yes you can stand it up), or, for infinite headroom (I say this because, if you plug the THIS TH sub DIRECTLY into your AC outlet, you will bet over 140 db of 60 Hz. before a 30 Amp breaker will trip), the OThorn from Josh Ricci at Data -Bass. You can Email him for free plans. I own one and it's the lowest distortion bass possible in that type of cab since it uses either one of two B&C 21" drivers. The slighly cheaper one models a little bit better in that cab than the more expensive one I have, but Parts Express doesn't carry it, so here's mine:

Finally pieced the system back together with the MiniDSP HD 2x4. It works like a charm. After a couple missteps, I got it dialed in and it is exactly what I was looking for. I have never used one before so I cannot compare it to anything, but it did what it said it would. It was fun boosting the bass and adjusting the frequency for the boost, plus adjusting the crossover on the fly. I am sure I will play with it some more, but got it to a point that I like what I hear (currently)!

Finally had time over the weekend to replace 8 main power supply capacitors on my Sunfire 12" sub and hooked it up with my Belle clones.  It had developed a constant buzz and I emailed Bob (Carver) about it and he had let me know which ones were suspect to change out.  I had emailed him January of last year and already ordered, and received,  the capacitors.  But, with the new house build, that got put on hold and things were in storage.

 

Ok, I can live with this for a good while now. Having no low end to speak of was making these speakers less enjoyable to listen to and I had preferred listening to the CV VS-150's and Infinity Quantum 3's which had bass.  So at least now I have "something"...albeit not perfect, it's way better. I have it crossed over around 60hz so far which seems to blend pretty well.
