This thread needs some life smile.gif . Wondering what anyone thinks of my idea of using side subs midway up the rooms length on both left and right walls..
I want to use dual 1200ci drivers with a HX800 amp. Build two sealed boxes that are 2.1cu and place one at the left side & one at the right side, the cabinets will measure 40.5" tall by 14.5" wide and 7.5 deep. The reason for such odd dimensions is so they fit into the side columns in my room, had the columns been wider I would use 15" drivers but they are only 17" wide. The drivers will direct sound forward from the sides toward each other across the room, the drivers will be placed low in the column. I've done cabinets that are narrow before for my rear rythmik subs with excellent results, as long as the internal volume is correct it works. I have to decide how I want to connect the side subs to the denon 4311ci, both outputs sub1 and sub 2 are being used for the other 8 drivers (in 5 kits). This will bring up the subs too 6 kits for a total of 10 drivers . Would appreciate any input /ideas on the best way to approach
Connectivity for overall balance of the subs.

Sub ci kits presently 5 will add another total after 6
2. 600 watt f25
2. 370 watt f15
1. 800 watt f25

Here is a picture of the way I incorporated the rear subs into the back wall and one of the column I will place the 1200ci cabinets.

Floyd Toole thinks it's OK.

I've wanted to explore building a DIY Rythmik sub but I am not sure where to order the parts. I'd like a couple 1510 drivers and PEQ600 amps. Do I contact Rythmik directly for a quote?

I built two of the rhythmic subs your looking at and couldn't be happier. I have built a total of 3 subs over the last three years, and Enrico and Brian have answered every question I had. There support and product is top notch. Just give them a call or shoot them an e-mail, they get back to you pretty quick.

These are my latest DS1510 with peq600xlr3 amps.

Good idea. Even better if you can centre the driver at the midpoint of room height.

Interesting, why midway up height of room? Please elaborate I am open to ideas and yes I can do if I want.
Thanks

Same reason for placing subs "midway up the rooms length". There are big peaks & nulls at the midpoint of any room dimension. Peaks can be pulled down with EQ, but it is impossible to similarly boost your way out of a null. However, placing subs in those nulls can minimize their effect (hence the suggestion).

I did give this some thought, same reason for having subs at the rear all to minimize or eliminate peeks/nulls smoothing out the frequency . Thanks for pointing it out, I'm glad you brought this up. In the case of my room, I'm hoping it works out as I intend to put the sub in the column that is closest to the mid length of the room which is 24'. The columns middle is
13'.6" from the front wall, not quite the mid which should be 12'. I suppose I can do it at 12' but that would be more work. If you look at the photo showing the columns the one closest to The seats is where I will install it. In that column,high up is a JTR T8 side channel, i have two rows of side surrounds all JTR T8's, below is where the sub cabinet will go. And the other sub driver across the room in said column. I like how the HX800 plate servo amp has this flexibility of separating the dual drivers. If you look at that same photo between the columns is where I could place the sub with a lot more work,and then instead use the 1500ci drivers. What do you think? Then I have to decide how best to connect the side sub.eek.gif
Thanks for any input.

When you said "midway" up the room length, I thought you really meant mid way, not 18 inches from that location. IF you can put the subs at the midpoint of room length, then that will be help smoothen out peaks & dips around 24Hz and 71Hz along the length of your room (i,e., make the bass more consistent between your two rows).

Then I will do it right. Sometimes it takes a little bit of thought and re-think things, i needed to hear it so thanks for the frank input. Also I will use the HX800 amp with the 1500ci drivers and not the twelves. What are your thoughts on connecting the sub. This will be a different location from sub1 (front subs), sub2 (rear subs). I know I can hookup the side subs at either the sub 1or 2 output but then they would just be sharing the output and balanced the way Audyssey does a single output unit. I'm thinking of connecting the sides to the rear sub2 output and see how it goes from there. The 1500ci drivers are out of stock according to the Rythmik website. I'll call Brian about availability .
Thanks

Could you also let us know what is in the works and options available in the near future?<br><br>
This will help many of us that want to save money or have an custom finished enclosure made.
This is awesome. I was going to start a new post asking if anyone built one of these sub but decided to do a search first. I love this forum.

Hello everyone, I am glad to meet you all. Now that I read this thread I have some idea what I' m up against. Most of it I understand, some I don't. But I will. Any way. I want to build two dual 12" DIY boxes, for my HT. I think i should have four boxes, but that's just me. I also want to build a sub box for my center channel. I'm not sure of the size yet, but I will have one. I have been using a center channel sub in one form or another since 2004 and it make a great difference to me. My room is 14 x 22, and I have had as many as 8, 10" subs in here. Any thoughts?

If it doesn't kill you...it hurts like hell.

The 1510 driver is designed to be used with the H600 amp. That's what the "factory"-finished F15HP has in it. The regular F15 (non-HP) has the 1501 driver and A370 amp. Because of the higher powered amp and greater maximum-excursion driver (1510) in the F15HP, it puts out a little more SPL than does the F15. In addition, if you build a DIY F15HP, you can make the enclosure 4 cu.ft. instead of the 3 cu.ft. of the finished version, which will give you still more output. The F15 DIY plans on the Rythmik site are for a 4 cu.ft. enclosure.

thanks bdp24, i'll go for 1510 + hp600 and make around 4 cu ft box.

Good choice, I made a pair last year and have not regretted it one bit. If you have enough room and funds I would suggest you build a pair of them. Three years ago I built a single sub consisting of the 1501 and 370-PEQ3 and it is now residing in the wife's music room which is smaller than the main theater room. I built mine using the front firing plans from rythmiks website and finished them in Grade AA cherry veneer to match my Klipsch speakers.

DIY is a lot of fun and very addictive BTW

Yeah, it's a great way to go, just what I did. With the cost of materials (MDF or Baltic Birch plywood, finishing, etc.) it might end up costing as much as a finished pair (at least for us U.S. residents!), but you can make them any dimensions you want (as long as the internal volume is around 4 cu.ft.), finish them any way you want, brace the Hell out them, make a "sandbox" version if you want!

Brian Ding's collaborator at GR Research (the "G" in the F12G model sub refers to GR Research), Danny Richie, has plans on the GR Research website for a sealed enclosure with an inner and outer box, the space between them filled with sand. The sand absorbs the vibrations in the MDF walls of the enclosure. The plans are for the 12" paper-cone woofer, but the sandbox idea can be replicated in a 4cu.ft. box.
