Risers for short floorstanding speakers?


Hello,

I purchased a pair of Spendor 5se here on Agon about a month ago.  The speakers sound fantastic in my room, but they are short (30" high).  There are a few different chairs/loveseats/sofa that I have used in my music room, but being 6'2", and the height of each seat, leaves my ears anywhere from 6"-1ft above the tweeter of the speakers.  

Everything I've read on this forum about tweeter height levels, say at ear level or above is best.  I can achieve this by sitting on the floor, and the speakers do sound better when I'm on the floor, but I don't want to do this all the time, naturally. 

Has anyone used any type of riser/stand/block/slab/etc.. to raise a floorstanding speaker?

I have a pair of Auralex monitor pads in storage that I'm going to try, but I think they're only a few inches high, and not sure how they'll do on carpeted floors.  I might have to put a tile under them too.

Any suggestions from those whom have had this issue would be quite helpful.

Thanks

Before you buy anything you should try tilting them with the rear lower than the front. That just might do the trick!  
@yogiboy 

Good idea.  That thought had crossed my mind.  I have blocks of wood, or longer spikes I could put in the front.
Build your own stands that will allow the speakers to be tilted as stated by yogiboy. Speaker would set onto stands with stands spiked to floor. With the slant stands need not be too tall. 
I dug up the Auralex monitor pads from storage. The box still had some slanted foam wedges that I wasn’t using previously. I put the wedge and pads on top of a tile square (the pads don't rest well on bare carpet), removed the speaker spikes, and placed the speakers on the pads. The Spendors fit perfectly on the monitor pads.

The top of the pad has some type of synthetic rubber material that keeps the speaker from moving. The speakers don’t move or wobble unless I really try. Not quite as stable, of course, when using the spikes in the carpet, but pretty solid.

The wedge angles the speakers high enough now that the tweeter is pointed just slightly above ear level. Almost an inch above.

So far it sounds better than without the Auralex pads and slanted foam wedge, maybe a little lacking in the bass when I turn the subs off compared to spikes in the carpet (and subs off).

I still need to do more listening. I’m thinking I need to use something else than tile squares, but that’s all I had in my garage. Maybe something heavier for a base like granite or marble. Maybe a heavy wood that I can install spikes into the bottom.

Anyone use a similar setup?

How much more height do you need to add to the speakers to get them to your desired listening position?
@lak 

I needed to raise them about 5 inches.  I have done this (temporarily) as I mentioned above, as they are slightly slanted upwards and elevated about 3 inches.
To look classey, how about something like this either purchased or made by you?

Those look great.  Thanks for the suggestion.  I would probably go DIY though, as those are quite pricy for my budget.
I have found that the smaller bedrock stands, made for monitors, actually work quite well with small floorstanders.  I've used them with Vienna Bach Grand and Dynaudio Focus 220 mkll...I had the exact same issue as you...ultimately I bought Salk SongTowers which are both taller and have all the drivers on the top third...
Will change the time and phasing of speakers .
I previously related my search for reasonably priced solid stands for the Gallo Ref 3.5's.  Many of these enhanced maple stands cost upwards of $1000.00, for common wood of all things.  Searching the internet, I discovered a material used in shooting ranges to stop large caliber high velocity bullets.  I gave some thought to the high energy absorption required of such a material.  I thought the characteristics required for that application could be easily transferrable for use as loudspeaker stands.  The website is the following and the product is described in detail:

http://www.blackironrubber.com/ballistic_rubber.html

I ordered two blocks of vulcanized ballistic rubber.  They measure ideally for the Ref 3.5 platform:  8" x 8" x 16" and are very heavy and solid at 41 pounds each. 

I would never have believed such a dramatic transformation in the sound of these speakers.  The overall impact is tremendous.  The resultant bass is the equivalent of adding two high quality subwoofers without the expense and complexity.  The bass is not only fuller and deeper but has greater layers of detail and tone color.  There is more range and nuance.  The mid and high frequencies likewise have a three dimensional quality with subtle cues previously masked by the lower profile of the speakers directly on the floor.  Horns are not anemic sounding but very full with the appropriately realistic sound pressure levels.  You can hear the individual notes on each string of a guitar.  What especially amazes me is it seems I have gained more efficiency.  The Ref 3.5's play louder at the same volume setting I previously used.  The soundstage is much wider and deeper with the instrumentalists moving farther into the room without a loss of depth of field.  Also, overall clarity is substantially improved and the experience seems cleaner overall.

These loudspeakers absolutely need to be raised at least 8 inches off the floor.  The tweeters are now at my seated ear level, 8 inches higher than stock.  I previously had them slightly toed in but this is no longer necessary.  I moved them about 6 inches closer to the center line and pointed straight ahead.  They are positioned 10 feet apart and I sit about 12 feet away with the woofers facing each other.  

There are two minor cautions.  These blocks are priced at $41.00 each but the UPS ground shipping is costly due to the total 82 pound weight, or about $1.00 per pound.  They are made of vulcanized rubber and have a pronounced oily rubber smell prevailing in the room when you first take them out of the box.  I helped to disperse this by leaving the window and door open all day with only the fan on the HVAC operating (my dedicated room has its own HVAC).

This is the best $158.00 I have ever spent.  Seriously, this is like getting an entirely new music library and loudspeakers at once without spending exorbitant amounts of money on high end audiophile approved products.

doesn't break anything to try raising them but most good speaker makers will design and voice them intending a certain position.  KEF for example specifies that stand height for the LS50s should not exceed 24", well short of ear level tweeters for most listeners.   The have designed them to yield the smoothest frequency response in that position.
The intended position (which is defined by default for floorstanders) assumes a tweeter height and position from the floor for bass reinforcement.  You should assume that they voiced the crossover design to yield their intended frequency balance at the listening position for the speakers placed directly on the floor.    in other words, don't get hung up on tweeters below ear level because chances are has already been compensated for.  
@kodak805 
thank you for detailed response.  I will definitely look into this.

@avanti1960
That's a very valid thought, and I agree one would assume as much.  Why would Spendor manufacture a speaker so short without making the necessary adjustments?  However, lowering my seating position/and raising the speakers have yielded in noticeable improvements in sound. 


If you decide to pursue this some additional thoughts.  With the open window and the HVAC fan on all day it still took approximately a week for the smell to disperse.  If that is too long a waiting period and the smell is offensive, I understand outdoor sun exposure can shorten that time considerably.  In any case after a week there was no longer an odor.

The other issue is possible stains on pile carpeting or a wood floor.  I have porcelain tiles over concrete so I had no issues.  Until the rubber completely dries, I would put a sheet of wax paper or clear wrap cut to the proper dimensions between the bottom of the block and the flooring material.  You would not see it and your floor would be safely protected.

I hope this helps and wish you success with whatever course you choose.
I took a look at the soundocity outriggers online. They look like just what I need.

Anyone use these before with floor standing speakers? Looks like some of them are adjustable and you can tilt the speakers as desired.
