New speakers - masses of boomy bass

[Mikeandvan]

I should add that this problem wasn't as bad when I had the Epos es11. I'm now considering Spendor S3 or AVI Nuneutron, any experience with these and a olive Naim set up? MY amp system is nac72/140 (with Avondale minicap)/Teddycap.

Have you considered the Totem Arro Mike? They're nice sounding little things and don't boom.

I was thinking stand mounts, in the belief this would stop boomy bass, or is that very ignorant? Can anyone tell me whether my 140 (has the Avondale minicap upgrade) would be enough to drive the SPendor s3/5r? I have a Teddycap to power my 72.

An easy load but low sensitivity (81db) so depends on what levels you want to play at and how far from the speakers you sit. Bass is already down 6 db at 76hz so there will be no deep bass to cause any room issues. At the same time this might mean the speakers will sound 'small'.

just an idea mike,i had ditton 66's and the bass tended to be boomy if sat straight on the floor,i made some mana sound bases for them and that tighten up the bass a lot.

That is very low. Gonna need some power to get those cones moving usefully to room filling levels.

Thanks everyone, some useful info, even though I've owned Naim kit for a while, I'm still very ignorant on hifi technical terms!

Hi Mike, I run mine ('2 version) with a Quad 306, rated at 50 watts, room is 13 x 12, I find I have plenty of volume. BTW, the sensitivity is 84, not 81. The sealed cabinet really helps bass control I find, really surprising the firmness and depth they can do, I had larger ported ones before and much prefer sealed cabinet bass.

I was going off the independent measurements from 'Stereophile' rather than the manufacturer's claim.

I live in a 1st floor flat, so suspended floorboards, as yet I haven't tried anything like stone slabs, for now the Talisman just sit straight on the floor as they seem to have different size holes for the spikes to the Templars, so will need to get some new spikes to try that. Room is sort of L shape - well not so narrow, but lounge with kitchen off lounge in same room and carpeted. I suppose filling the front ports would foam would dampen the bass a lot? Any thing else to try before I go back to stand mounts?

^^ This.

Lots of good advice so far, Mike, which you should follow. However, unfortunately the problem will not go away (or be lessened) until you address the issue of isolation, and in that respect, install something effective.

No loudspeaker with a decent bass response I've ever used on a suspended wooden floor, has failed to boom, simply plonked on the floor with no spikes or stands/isolation platforms. Therefore, no matter what else you do, until you fix that, your room will continue to 'sing along' with the music, but not in a good way!

Also, if you can, posting a couple of good, clear pictures of your set up, from different angles, might help us advise you in some other way of how to optimise things, perhaps with speaker positioning. Mains (and cable) issues can often also contribute to boomy bass.

Is all your kit, for example, simply plugged into a cheapo 'B&Q mains block'?
