Did you look at alternatives to the Trinnov - any knowledge of the DEQX stuff?
Cheers, I demo’d Trinnov but chose a Lyngdorf unit - a long time ago though and much kit has come/gone. Am using an Integra 8.4 Dirac as a stop gap at present. The dealers I use have Lyng, Trinn and Storm products on demo, not heard any DEQX and am curious about it as I’d heard their new kit was on the way.
One of the demo rooms is a £quarter mill Trinnov with tiers of seats, had a quick listen last visit, I‘ve been using another simpler room recently cos I was upgrading my Hi-Fi not AV. Last year they put on a couple days to show off the Trinnov unusually with old B&W Nautilus flagships.
Serious stuff. I heard the Trinnov in a studio control room, B&W801s and some subs (do not recall what), and a properly acoustically treated space. What the Trinnov did was quite remarkable in tightening up the sound and getting things ‘right’, and there was no low hanging fruit acoustically to correct, it was already a good room.
When she asks you for something, negotiate for a second sub
They only went and sent the wrong colour lol. Opened the box, took off the protective cover and thought to myself that looks quite shiny. Checked the box and it's Piano Gloss Black and not Black Ash. Contacted the shop and they will arrange for DPD to pick up and swap over, but not till Wednesday
SPL depends on volume displacement of the driver, and if excursions are the same, it comes down to the effective area of the cone. So two 8 inch drivers will have roughly the same area and, therefore, SPL as a 10 or 11 inch driver, assuming identical excursions. You need four 8 inch drivers to equal a single 16 inch, assuming X max is the same. Typically, however, larger diameter drivers have larger X max values.
Trinnov has the best off the shelf DRC. Tact, Lyngdorf, DEQX, Dirac are not as user friendly and

Agree
Bass extension by itself, i.e. -3, 6 or 10 dB points, is meaningless unless the woofer can produce useful output at those frequencies. So a compact dual 8” woofer may well go down to 23 Hz, - 3 dB, but is not likely to produce very much distortion free output. To produce reasonably loud deep bass requires a lot more SPL than folks think. Have a look at the Equal loudness curves here:
Yes , I haven't mentioned at what SPL level -3dB point was , 23-240Hz +/-3dB @90dB , 2m ground plane and I'd expect measurement being taken at reasonable distortion levels but when choosing adequate subwoofer one need to consider average listening levels and room size and what is the purpose of the subwoofer in specific application as in my case subwoofers were used to flatten frequency response and minimize decay times rather than reaching lowest depths and opening another Pandora's boxBass extension by itself, i.e. -3, 6 or 10 dB points, is meaningless unless the woofer can produce useful output at those frequencies.

James Larson’s reviews on Audioholics are the best, perhaps only, source of subwoofer data.
yes but @40Hz is 60dB@1000Hz
