What would be your ideal sub?

[coreysinger]

Is it ported or sealed? single driven dual passive
What size? 15
How much power? 2400w
What type of finish? Like the rest of the ER line
Features and such. meh... it will sound good
Last but certainly not least, how much? (please keep it realistic ) $2000 a piece. I'll take 2 please.

Lonnie's looking for new projects to work on. This is the second new product he's asked for input about in the past few days

Hmmm...he must have all of his other big projects completed and in production.

You obviously didn't see my post in "The Man from Emotiva" thread in the News and Updates section of the Lounge.

"I had a chat on the phone this morning with my old friend Dennis Burger. I mentioned what a nice article he wrote about our leader, Big Dan Laufman. He confirmed what a nice guy he was. However, he wanted to know if by any chance I knew who the guy was who he saw doing wheelies on his Harley in the Jade/Emotiva parking lot?"

Apparently Big Dan thought it was time he gave Lonnie something to do like the sub survey.

I wish I had time to do wheelies in the parking lot! ;D Truth is, at any given time I have between 20 and 30 projects in the works. But hey, you never know I might get a wild hair up my @$$ one day and give it a try. ;D ;D

I think there are two different customers for a sub. There are guys like me who have full range speakers that play quite low and have no need for a sub for music (unless you are a total bass head or are into house or rap. Even still..) My sub is just for HT.

Then there are guys with monitors and even with floorstanders that don't play that low that need it for everything. Those guys seem to prefer the sealed sub for speed but I'm not sure you really do. My SVS does everything well with the plugs out...

[Chuck Elliot]

I have a couple of comments on the plug selectable sub. The enclosure volume for a sealed sub and a ported sub are usually quite different given a particular driver. So, an enclosure that can be used both ways would be a compromise. Go one way or the other. I prefer the sound of a sealed sub.

I would like to see Emotiva make a completely passive sub where you could select your own amplifier to go with it. This would open a number of avenues. The primary one being that Emotiva could also design a sub power amplifier with a bunch of features.

[jdskycaster]

^ +1 on minimizing the compromises. If this is to be really competitive it needs to fit the mold of current Emo products and deliver more performance for the dollar and approach DIY performance but with commercial fit and finish combined with better reliability. Currently I have only ported subs - MFW15 and two CHT VS18.1's. Have yet to have anyone hear them in my system and say they are not fast enough. I just think commercially a high output sealed design will satisfy a larger audience if the compromises made are minimized and it delivers solid price performance numbers.

+1000 on the passive design with outboard amp as this creates flexibility and would be a niche for Emo over others offering only fully packaged subs (of which there are already a ton out there).

alksfsdfhkjhhthis is where I type


It's interesting to see comments about price needing to be lower than other ID sub makers. I would assume that the pricing would be pretty comparable. And that they might need to do something to make their sub solution different.

For instance, maybe a simple TACT implementation. I say simple, not because TACT is simple, just that it would only have to work for 15-100HZ or so. Just plug a mic into the DSP and let it sort your room out for you. That would definitely appeal to me.

Or a separate sub amp/dsp, with a variety of enclosures. 10", 12" 15", 18"? Maybe with the goal of having sub diversity, for people who are only looking for HT LFE information, then 15", for those who want to help out their speakers, a 12+15. And have the DSP sort each sub separately.

harri009 I definitely hear you on all the comments from other members about the Rythmik subs. I would think that Emo would need to do something to make theirs different. But I do think that those could be good targets.

roadrunner I agree, the ERS-112 and 212 are defintely the model for what I'd envisioned for my subs.

Porscheguy I couldn't agree more, regarding 2 separate "groups" of users. Those looking for support for their mains and those looking for LFE.

All of this actually makes me wonder whether the questions that should be asked are not about the "design or what you want" but rather having people describe their system and what they think they want the sub to add to their system. As an engineer, I often find that the customer/user often doesn't really know what the best solution for them is. They have some ideas about what they might want, all valid, but that sometimes gets lost. We have this printed very large on the wall at work:



For instance, I would say that I want my sub to have a DSP/PEQ to make sure that I get a nice flat response, but my system will have an XMC-1 in it, and the TACT in the XMC-1 might handle all my sub DSP needs, in which case I'd rather not pay for the DSP twice.

To start that off, my system is/will be:
XMC-1 (as soon as I can get my greedy little hands on one)
IPS-1 (though the mains might get upgraded to nCore amps)
R&L - Magnepan 3.6's (34-40Hz)
Surrounds - Magnepan MC1s (80-24kHz)
And I may get a center CC5 - (200-24kHz)

For two channel listening, I'd like the sub solution to be able to get my speakers to be flat from 20-20k. So it would just need to be able to go from 20Hz to say 40Hz.

For HT, it would need to help out the center and surrounds, and have enough grunt to do the LFE justice.

Hi Lonnie, I feel that any sub you guys design and sell will be a very good sub. The best driver, amp and enclosure you can use at the price point will make the best sounding sub.

Now what I would like to see in your next subs are multipule connection possiblities similar to the REL subs.
Their high level speakon connection from the amp or reciever speaker outputs makes 2CH integration easy and effective. Plus the LFE connection for movie sound tracks. This combination makes for the best of both worlds. I really can't think of any other manufactures that uses this method of dual connections.

Thanks

Interesting. I did not know that. Do you use both connection methods? How do you like the integration with the fronts for music?

Thanks
Mark

[traider79]

I would say15" or dual 12"
Sealed or ported either works as long as it goes down to 20 preffered 18
Watts the more the better. Knowing how you guys like a lot of power like I do I would say atleast 2000 with dsp. I would also like to have the amp seperate from the sub if possible. I know it eats up rack space..
The finish matte would be nIce Since the piano finish reflects light.
Pricing for this would be around 1000 to 1200. Well 999 to 1199 it just looks better on paper.

[ÈlTwo]

Wow, no love for the SVS .
Is it a compromise, or just well designed. Either way, I love my sub, one port plugged.

[GTPlus]

I am excited to see the comments for passive sub/separate amp.

Shameless plug for the standalone sub amp poll, in case any one missed it ;D

emotivalounge.proboards.com/index.cgi?board=amps&action=display&thread=27570&page=1

[jony1600]

Is it ported or sealed? Definitely sealed( love the sealed sound)
What size? 12
How much power? more than the x ref 12
What type of finish? doesnt matter
Features and such.- my main concern is to have a subwoofer that has a detailed, transparent and reference type of sound... if its possible sub 20hz would be phenomenal, although again quality over (SPL/Hz)quantity. oh and the GUI that was talked about with the mic would be nice also.
Last but certainly not least, how much? 1000-1500

[jony1600]

Actually, this just came to mind... what if the sub woofer has a front firing 12 inch woofer and a down firing passive radiator

I've yet to have one friend over and not be wowed by my dual ported SVS PB12-Plus subs and I'm talking music and movies. I won't be changing them out anytime soon. As for Lonnie's question, I'm like RoadRunner, the original ERS-112/212 subs that were proposed a while back would definitely get my attention for a two channel room.

[Gary Cook]

My current sub is 17" front firing with 2 vertical ports and I am very happy with it. Except (well, we always want more) it needs a better/bigger/more powerfull amp. With the amount of air it moves it's fantastic for HT and, utilising the USP-1 base management, it's not too shabby for stereo either. So I don't mind what the speaker or its box is, I'm sure it will be fantastic. I just want a separate Emotiva sub amp, with the usual Emotiva power/qualtity for money ratio.

Cheers
Gary

My wife complains about the bass now, and I only have 600watts, 3 ports (2 pluggable) with 2 12" downfiring drivers.

An ideal sub, for me, would be something similar to what porcheguy posted, but I'm leaning toward 13"

[Topend]

Sealed
15" driver/s (option for single or dual)
600+ watts
PEQ
Timber veneers (Jarrah)

Aim for great SQ, not super high SPL.

Cheers,
Dave.

[Topend]

Maybe sell them as a user assembled kit to keep shipping costs down.

Just don't forget that the sub has to reproduce the LFE channel that is +10dB's versus the other channels and that is 115dB's at reference level.
